And probably where it just works here is for writers where we also have a social science managers faculty who are working on missions around our society. Herds presentations and tech serious people are here quarter results from the work with the emergence of tracking first through the literature. So I hired that group and had the pleasure of meeting colleagues in the NOW area when I was in South Africa last year. So one of them has reciprocated the visit and come to see us in a spending a couple of days on campus. So I am delighted to introduce Dr less the same way. Actually he and I shared institutional affiliation. Because although I am a full time professor at Texas I also have an honorary position at his university the twenty University of Technology which is in a city that you may have learned in your geography classes was called Pretoria. But it has been given back to its original name trunnion is the capital city so that so less he has a Ph D. in chemistry from another university in the area of the University of Johannesburg. He works on a synthesis of carbon nanotubes by nebulized spray pyrolysis and particularly works in catalytic processes which he can talk about much better than I can because I'm the professor of public policy but I do have a correct something in his but I actually think actually now that I'm living here. I think a matter of the beginning leaking here like you're right he would be here to wheel chair instead of standing actively in front of us it was eleven years of university in your hands for one hundred twenty. Right around to pick him up a scene where. They are said he's going to talk to us a little bit about his own work. I think that particularly at the. Correction Manor scientists and engineers in South Africa will come together and form the South African animation So Leslie thank you very much for coming. Thank you thank you. It's a very special reading about a microphone. Just for the room. I'm not sure whether I can really have a bet if you care and then I suppose I don't need the out of my. I made a comment to Susan some time this morning about how Cosmo pointed to the U.S.. I'm amazed at the flag in so many places as one goes into a plane from one city to another if you had to be brought to blindfolded you wouldn't be able to guess what. What country you're in and I really find it amazing and I think it's not spoken of as much as it should be quite interesting. Thank you very much everyone for coming through. My Maybe they're going to pronounce it. So it's an early summer for African languages the Zune do not wait in particular has a lot of those plagues But over the years gotten used to just heavy to pronounce just right about anyway. Really. Because even we didn't buy our own country only about maybe twenty thirty percent of the population can pronounce it properly. When I prepared the talk that I'm presenting now the brief was to give a general sense of what is going on in nanotechnology in my country. And what you'll find there for you it won't be very specific on any project that I'm involved with or any project which is going on in particular but the intention is to give us a sense of what is going on. How we got there. And where we are hoping to get to with nanotechnology. The outline of the Tom Daley is. Firstly I want to talk about the development of nanotechnology in South Africa. That relatively young field is a young field internation anybody even younger in South Africa because you appreciate you are nowhere near the stage of development that you guys are here. And give you a sense of the types of activities that are going on. It's not exhausted but I've taken a list from one of the conferences we hosted a short while ago and it does give us and some of the variety of programs or projects that are going on and out be remiss in my duty is to my employer for I didn't mention something about the university where I come from. That's one of the universe of technology and the little bit of knowledge technology which we just started at that institution. And. Finally I would say something about an organization known as the South African nanotechnology initiative which I have the honor of chair in until the next election as of who's later on in the year. For those of you who aren't familiar with South Africa the country. I'm sure you would at least be familiar with the fact that it's on the southern tip of Africa. I suppose the name data suggests that the main industrial part of the country is in that area where the two largest cities Pretoria in Johannesburg are located between it is the capital city. John is big city by fire in the country. Are referred to a few more cities during the course of this talk because the main centers of nanotechnology in the country are located in that area and there's one other major set in Cape Town. Although I must say right away that. It's not as if those are the only two centers that have. Not a technology related activity. The fact of the matter years virtually every university. Or institution of higher education in the country does have some nanotechnology activity but the main center has will be in those two places. I found this on the Internet. That's not prejudge it looks like from a distance in federal court two of the. This was taken from the laws of the Union Buildings which is our parliament in South Africa and it's a view of the city and the campus and we are come from the side of the campus of the university is located somewhere in that area or in this part of the city. I can make out one or two buildings that make up my campus in the. University is one of the smaller ones in the country. But it has approximately sixty thousand students. And it's spread over five campuses. Three of them within three or four of them within Pretoria two of them. A good distance from the end of that. Historical reasons for that which I will go into in a moment. But he's talking out of technology in South Africa. Begins effectively in about two thousand and three. But I must say it quieted clearly right from the onset that even before that there was some activity in the technology. You'd appreciate the Fed There are people who do anything anywhere on the Tallis is heavily prepared in particles that are very small size much much longer than the Americans of the area that we now know it is not a technology. So there was somebody. But up to that point it was individuals waiting on the individual projects without much. Without much synergy calling on and without the people working in the area regarded themselves as head in March in column one. In two thousand and three. In two. That there are three of them there was a time when the solid rock and nanotechnology initiative came into being. And meeting was held that we each virtually everyone who was doing any work there could be classified even remotely as being in nanotechnology at the time we came together and we had discussions about what we were doing and where we wanted to be. The main challenges we faced was firstly getting hold of the equipment. The type of equipment we need for this kind of where it's expensive a lot of it is hardly are available in South Africa and on. Most of the equipment we use it has to be sourced elsewhere from Europe. Those are the two main areas where we could become strong. But the prices are such that no individual research or research group. Could come anywhere near being self-sufficient. And the only way we thought we could get it. We could get it get anywhere near heavy equipment we needed was by coming together and getting that active part in the formulation of a nation our policy towards nine hundred Milegi and short of that. Even though. Virtually everyone was excited about hosting a World Cup. Then some fines were left aside for the poor scientists who would much rather have had research you could do with some of the fans that we used to host the World Cup. That is very popular statement I can only make it safely and freely when I'm outside the country but. There is some truth to it. Believe me. So at that point. I Wonder Con team was formed one of the first two things we had to do was just call aides. Or put together a list of what was going on and where it was going on. Who was do you want them to put together a list of the equipment that was available. And then in that way build a database of sorts. Both about the capabilities and the equipment that was available. But without involved with the. God made at that stage. Not much credit been achieved. So an important role of the organisation at the beginning then was to influence policy. And. That's why. One of the first things that did to glue deed after the workshop was to consult widely and to ensure that government wasn't ward right from the onset. And without going through all the details of that diagram. I'll draw attention to the Fed that eventually what became known as the nation had been a destructive she came into being. Later in that. And that was reviewed it was prepared by Sadly it was sent to the Department of Science and Technology who if you get there. It made whatever changes they wanted to and then in the end it became our job to head. The nation or not it is going to strategy and a ten year plan for new technology. I rose out of that. I'll give you some more details on that now. What was important then was formulating a vision of where we wanted to be right about the near twenty fourteen. Which come to think of it isn't too far. And I suppose even knowing that. When you look back unified and you didn't actually start at the time when you wanted to start. Not every deal was delivered in time. So no doubt you wondered exactly where we wanted to be right about this time. But many ways we were hit with the progress we've made one of the important things that came out of this. Was certainly key. This trying to do to cooperate. Some key ideas that the country wanted to strive towards. It came through. Right. The greatest wrong at the beginning of that. There wasn't much sense in finding in the tape research or flights of fancy it was important. Therefore there is no fundamental way it had to be done. It had to be a law. I did someone a real mission imperatives. And this tragedy therefore draws on what is considered as important in the country and provided reduction. As well as. Getting something out of the industry that we have in the country. Taking advantage of some extensive expertise in biotechnology. And putting together an advance money for it into going to strategy. As a result of that process so that it can sit in focus areas were identified and the six important ones are the ones given the. It was fair bit astronomy that whatever it is that we do or not a technology had to in some way are now to address those key problems including the provision of clean and safe water to the population. Energy is a concern and which one in the entire world I would say much more about that. And to help. One of the biggest problems we have in the country is tuberculosis and HIV which are related. So there are still there are groups that are working very hard at using about newly acquired knowledge or not or technology to provide solutions to problems or to help problems such as a Soviet AIDS and. In terms of industry the money floating of materials was deemed to be important. And it was found that we had to why we are not there. And lend some support to the mining industry which is the cornerstone of the industry in South Africa. Then finally chemical and bottle process was the last one that was identified as. These six. The core of the activities that are going on. But it's not as if there's nothing else beyond these which had. But what's important is if you want a source they are finding that in South Africa one hundred knowledge. You tell it will be viewed according to whether it's a despise any one of those if you are likely you are unlikely to get much funding. If you can prove that you and Sam will address. At least to one of those concerns. Since then. The developments have led to the establishment of what is known as the flagship projects. What idea was key individuals and groups who were deemed to have the right expertise and who had proven themselves in some way or another way given the responsibility of taking some funding and converting their into something that would serve the purpose of showing the population what the capabilities of nanotechnology. It was found that continuing for years and years of doing research would doesn't produce results immediately when we lead very easily lead to politicians who control the funds to decide maybe our funds are better off using elsewhere. And therefore that the main function of the flow of projects was to produce results quickly result that would show or that would lead to convince in the people who matter. About the necessity of continuity in this line of work. And partly why that was happening. It was hoped that not so more people would try and various aspects of nanotechnology because it's an important part of the development as well that we have to really educate much much larger numbers of scientists and bring them into the phone. To make sure that a critical mass is attained out of which something can be achieved. And two nations are now under center has been established. One of them is at a place called me and Ted. It's just outside Johannesburg. Into headquarters in early May and. Stood for a minute or a minute then technology. But it spread much wider than that. And as far as not integrity is concerned this science center or the Science Council. Frequencies or want to what the treatment and the manufacturing of sense as of different kinds. As the rest of the responsibility is was never to the same to the council for Scientific and Industrial Research which is in Pretoria. That the two main centers in which God made a grand or they got funding directly from the government. And the way they way they do their own research and houses they employ in large numbers of qualified staff. But the facilities that they are available to virtually all the educational institutions. And none of us in South Africa will be able to do much without from time to time visited I don't want to be used to do simple things like. Especially high resolution. If you want to use an X P. As in South Africa. You will have to at some stage you are not abusing the C.S. IRA because they have as far as I know only one of two working systems which are in the northern half of the country. Which is why it was so fascinating for me to hear some time in this morning that Georgia has to be as facilities. You can't help thinking as you want in a place like this. How large the people in that regard but as opposed. In time you will get there. One of the more important results of that process was that the two programs the N.E.P. and the N.E.P. it came into being. And he stands for the nation and equipment programme and N.E.P. is it is a more focused one where you stands for the nation. Technology equipment program that bit of history here is would be in order not too long ago. The higher education institutions in South Africa we had run out of racial lines in such a way that there were very few institutions maybe three four or five little evader well funded. And the rarest of which at this stage would cause you've got about ten other universities. Basically got the crimes. And they were located in both expertise and equipment as well. What was important about these programs then was not only were they intended to provide a much needed facility or much needed equipment for everyone. But they were intended to address some some imbalances of the past. And that's a process which is going to be now. So every year. We compete for some funding which is provided by these two programs. And why. They've taken to our pound fortunately is not just the way the expertise lies because a bit would be the case then. The better resources into two institutions would continue to get better and better while the other ones would be left behind. So one of the two of the key point that they are looking at is addressing these are the kind of balances. As well as making sure that there's a redistribution of expertise in all the institutions and I hope was actually didn't to make some progress in that regard as well. And I mentioned earlier that one of the important views is just getting the numbers of educated people who will man the labs who will do the actual experiment and. So an important element of their use. The page the program which draws on resources both from the private sector and the science councils as well as the individual educational institutions intention is to have a program which accelerates the chrome with of expertise. The kind of equipment which is available and said to see as I don't mean to add includes what it would look to me if you were as run of the mill star that should be are going to be in every lead really but as the THEY HAVE TO DO you can go down that list. That's generally the kind if you could make that is housed in those institutions. I can say with certainty that there was a stage where virtually most of the equipment at least was available in our new one or two centers in the country but that's changed quite a lot in the last few years and at least. Outside this terror of the university is high resolution to me still a bit of a problem using it to maybe drive around a bit before you can get your height isn't in terribly good working order. But we are pleased to have the security of knowing that what is not available at an individuality will be available at one of those two. But occasionally we do we have to get out of the country as well. Drugs as more equipment in that which is not available in a way in the country. Rather table summarizes is the nature of various kinds of technology related activities which are going on in different institutions. The first few ones on the left and side are totally educational institutions universities and colleges. I doubt if you'll be familiar with the names but one of the below ones is you city there's the University of Cape Town. And the Vance university those are the two most established universities in the country and he will see that range of activities includes virtually everything that is going on in the country from biomaterials catalyse ceramics composites drug delivery electronics. Not a particle is another point of assembly where as as you go further to the right inside you had a lot of more of the established institutions which had maybe one or two sentences that conduct some activity which may be the Internet technology. Fair on the right inside I decided to mention D.C. as odd in the meantime. But the Medical Research Council. As well as in there which is the nuclear energy facilities in the country. All of those have some activity as well. And finally. To complete the picture. If you company is one of the bigger ones the energy facility the well they're not at the end for what do they call it. Against producing petrol or what we refer to as petrol from coal or oil from coal that made a claim to fame. This is not exhaustive Mendip because it's quite difficult to get information out of the industry about what they're doing now. What a lot of companies that are doing something about nanotechnology but it doesn't make too much sense to include them in the least if you don't have details of what it is they are doing but we know for a fact that there's quite a bit more activity going on. But then this is imported as well. And I'd like to draw our attention once more to this because that summarizes the range of activities that are going on. I'll speak in more depth from now about either projects. If you compare what is going about in South Africa to the well you'll find that there's a much lower synergy in more developed countries between getting idea of developing it and getting to commercialization. Whereas we still have a camp that we need to sort out. And in addition the doctor. Well only just getting into that side of things where Commissioner lies in what we are doing. And this is the news I spoke about earlier just to give you a sense then of the kind of projects that are going on. Running out of food is based on carbon nanotubes it seems like a long time ago now by there was a time when just synthesizing nanotubes would get to your publication just making them about how you make them and how you modify their properties. It's surprising. Funny enough that even occasionally you still see a paper which is based on See this is there nothing else in general such as a car born in chemical physics in letters and in many cases those materials when used as nobel supports for catalysts the kind of companies that a company like science would use for future trouble synthesis. And this is the season of quantum dots and we are use an application. I've done a bit of this in conjunction with colleagues from the University of the way to keep using carbon nanotubes as material. Impregnating them with metal such as. Blood and I mean that and using those for fuel cell technology. Specifically and proton exchange membranes for human cells related applications. That groups are great to work. You know and containing nano composites there's a group working on the optical properties of Kate my mother's side in zinc oxide the preparation interviews going in lots of properties of porn and an accomplice it's. And I would say the same as I was about the on the facility that has the range of his age and equipment required for the measurement of those properties. The use of carbon nanotubes in photovoltaics. Biosensors networks. And this one in particular is the kind of radicals wanted me to like I said they're the ones who work with sense as the last two on something that's happening there. The nuclear energy facility. Then you get an image of us Lutie is doing some work on using public money to contain the waste or waste management and there's use of microfluidic devices in one particle so this is a lot of data property is one of them oxide reborn see in the season kind of at his age. I won't read all of them but poses for a second or two on each one of them to give you a chance to just go down the list quickly. And as I've pointed out and I did this is not exhaustive it was card fraud. I think with one or two conferences we hosted in the last day or two. Like I said the idea was to just give a sense of what it is that's going on. This one is quite an interesting one because it is a byproduct of some processes. It's always material in fact. But what group is found innovative ways of using that in the political action of wartime speech only as it might invade age which is what has been in the news quite in order lately. My suspicion is you wouldn't read too much of it but women still has conceded the country that it's predicted that the course of mining activity which has been taking place over a hundred. Or a period of more than one hundred years in the country. In many cases those mines shots are left up. They are bonded afterwards ones are limited extract and. When there's no system of pumping the water out. It rises up with the water table. And it's predicted that not too long from now could be encountered in that water on the streets of Johannesburg unless something drastic is done. So it's an area of major concern. And there's another fifty today in dealing with hazard mind drainage. I've mentioned drops in this is. And this is where we're just going on in the indicate an area on the use of nanomaterials. Point I'm a little I didn't. Put this in this is of those materials. Required to go on and I'm group metals producing and selling them so I do quite a lot of that. And it is a part of blind which is under construction somewhere and I don't think they are producing any results yet. But the intention is to produce nano titanium for use in lots of applications including sunscreens inside materials. And this is an important one as well. And then inside kid undersized carriers for drug delivery. It's pretty targeted in diseases like tuberculosis. And without going into a lot of detail I'll summarize what's shown here by explaining dead center in key indicators we identify and. So didn't reply I mean that would have to be met to indicate whether it was succeeded and what we're trying to do is in our technology society. One of the most important ones was just. Where could you see really desires that are of benefit to previously marginalized centers of the community. It's easier not to talk as research as about our finding needs about how much money should be going into research on the new technology but in a country that has. Serious challenges such as housing and food. It's not easy to ensure that you get that kind of funding but if you do get it and the onus is on you to show afterwards that it was then the money was spent well on what it is easier to. And the commitment impaired if negative energy is important as well like I said it's one thing getting the money but if you can show what you've done and what benefit has come out of it. Of that period of ten years or so. Then the entire effort to do will come into question. This is the energy which you are looking at this stage the technology transfer in the stands for black economic empowerment one of the made imperatives of the current government to ensure that a previously marginalized section of society gets to play an active role in the economy of the country. A very controversial policy as I'm sure you would have guessed. The institution with come from. Rather started in two thousand and four but I did qualify that by stating what happened in two thousand and four is that their deeds usually came into being from nothing. There was some realignment of higher education activities at the point which resulted in the manager of many smaller institutions to form larger ones. After that point about any institution known as the Pretoria technical on. And if you are in the area and day you were all brought together to form. What is now known as the University of Technology. Because of that he's done a college system as a technical. But institution only offered undergraduate programs mainly diplomas and certificates and he will realize as I show you the next few slides that research. And that is it is relatively young. The age we are used to the kind of black institution. I gave you will find it in this is that it to continue classifying institutions in terms of. The level of privilege they've enjoyed over the years because there are those imbalances to be addressed. But something which hopefully will be phased out soon. But at the moment I think this is added to make that distinction in many ways identifying the needs E.G. institution is. Tell the story in the country about where that institution is expected to be and how well hoping to develop in the near future. A very important challenge and virtually every institution in South Africa is the lower proportion of postgraduate students in the implications now here's where funding. The other time in that country where funding was based on the number of students enrolled. And therefore a good strategy for any university that wanted to get money was just going to get as many students to run as you can and then you have been covering. But that's changed in the last five to ten years. In the sense that a great time in France has been pleased to graduate students of what would have to do is post graduate students a master's in doctoral students. And it turns out that the funding model at this stage is about as much value in a city page do student is it rude or close to fifty undergraduate students. Which means if you want to have money for research. You need to change that proportion in such a way that we have a lot more postgraduate students. The ratio at this stage is really. It's a ratio is bad is maybe less than one to one hundred I would say. If you take about one hundred first year students. You would expect that you would have me. Maybe about one or two students or pages eleven. It sounds rather surprising but keep in mind when introducing that it wasn't doing any research at all just a bit more a bit over ten years ago that then it begins to make sense when you think of it that way but the idea that is let's get more postgraduate students. And unfortunately what that means is it's not just one institution. But virtually every institution in the country. The same students. Would put students in a very privileged position where they can sit down in just a little Cous often want and they decide OK I will go here and is going to head off for student accommodation spend a couple of weeks in say. And leave and go to another. And cases where students have been pulled from one institution to another not on the head of. But want to be more calm or to use their supervisor who leaves one in situation to another region to walk away with all the postgraduate students he was supervising I can feel good right now is a case where a supervisor left with about. About fourteen thousand Ph D. students. And this is fourteen out of a total of about twenty something so it was a serious setback to that institution. Where the T U two stands with regard to there is right now we have I think approximately thirty dozen postgraduate doctoral students. Which is you know but much higher than what we had probably say five or ten years ago. So the numbers are moving in the right direction but we're hoping to accelerate that and see it as improvement. And one of the measures were taken to address that. If they've been people like Professor cousins. Associated with our university. And that's doing one dies to. Stimulated. Among students to drastically clear the level of expertise. The president will be in the university. And the last point then which is quite important the institution is beautiful caused and developing that is its capacity and at this stage I would say the management would move heaven and earth to do anything that is said to to cause a change in those creatures. The nanotechnology group is as small as that it's basically four or five people. Got to that place. I've been at that institution for just over three years now. Or just under two years. And I came in I had my page D. at that stage after doing quite a bit of work on carbon nanotubes So this is in applications. And I found it easy to see that had. Eventually not been negative integers and a tad but they had been my area of interest. It was my intention to develop then. It's proving to be quite a challenge but I have two Ph D. students who are. In the second year of study already. And three masters students and I think by the time this month is over because I don't know my enjoyment begins in January. I'm hoping we're going to have another I noticed that the students. But mind you this is not deciding to turn off all the activity in the department is just the dinner to do it in area. The department has about twenty five members of staff members of the teaching staff and it's quite empty of spectroscopy and if you other areas there made a well developed groups. What spectroscopy. What is proved difficult to Study Group one hundred to. The difference Claridge. And the only way I found it possible to do so was to win to be associated with those groups that I was ready established including the group and Catullus is. A group which does some really good where want to research. There's a clue that made it difficult in our faculty and our professor more about why I think Professor cousins had the pleasure of meeting when he was at our institution. But the group would produce is about fifty percent I think of that he said publications in that in that area. And I'm a member of that group which sort of ties my hands though because it means any student that I or that I supervise in conjunction with that group have to do something on water purification or something like that. So in many ways the kind of activities that we are doing are dictated by the source of the funding that we have and. What is to be in good stead as well. John is back where I did my study is as well as because University of the area. The University of the of the verified as Ron also known as of its. And example of the kind of US Asian I have with them or do not believe I want to use they are just an ordinary day and I'm not even talking about high resolution Tim if I were to make a phone call now and say I'd like to comment is that the answer would be great. You can come in. On the second of May You would have be instrument rated for you in their day. A solution I've found today had they did search engine has a terrible cold relationship with them and I have after hours access to their labs and that meant instead of waiting until the second of May. I can just wait until their students are done for the day at about ten or so and then I walk in I can spend the entire night. Do you doing my Tim. And that's eventually the only way an institutional fall aside can survive. It's about making sure that you were. Alongside those that are established and use whatever equipment you can when time allows it. Department has a full range of under the equipment. Right. Very well pleased when it comes to spectroscopy and chromatography. But the equipment that I and my students are using is mainly in our discharge set up for super size in both civil wars in Kabul and in multiple carbon nanotubes. As well as a set up for nebulous preparedness is what I would refer to later on. We have recently acquired a T G A M. As it does the a C.M.S. as well. The lives that are much better and etc. Mainly use the T.J. for kind of that is in carbon nanotubes for determining the model of the not achieved as well as any composites that we make mainly been political opposites. And the maybe we do need the layers around one set up is a current and I've been energy of by determining the ratio of gravity to nine privatized cup on the so-called I G two ideas ratio. And the main things we do with its ideas characterize the catalysts. In the main these are supported and carbon nanotubes do we do things like determine because the clues are limited as well as determine the phases of the metals that are under support. And make an educated guess in some cases about the particle size. And the rest of the equipment which we use from time to time as I was at nearby institutions. My reason I didn't include those and you will see at the core if we do. So this is a kind of that is a shift in function as a ship. And the applications are. Include using those those not achieve that supports for metals in catalysis as well as water purification. I mentioned there to Ilya the neighbor setup which I put together this is our main source of carbon nanotubes for various projects that we're doing. It's a much smaller set up. A lot less capital intensive than other systems that I've seen and used. But at the core feed is the nebulizer it appears an electric transducer which is sitting at the bottom of that vessel. And is that of using the supported cart and is set up to use in what is referred to as a fluid in catalyst. You reach into particles the metal particles that can stream. Of course it has to be metal pre-cancer because you can bring in I don't particles that way so it has to be a prick as I like Federer's welcome to see it when you can see in depending on the metal you're interested in. So the idea is to dissolve that in a suitable solvent like tone of Eden and then the K.T. I guess it goes through that and once you get on my is this the event of a defined spray will be to find droplets which are created through to the fan. And he will lead different products and defend zones of the face where did quite a lot of work on these initially. And made it to publish by chemical physics and that as. The work was mainly designed or the main aspects of food where dividing concentrations are just changing the parliament has change and flow rates. Change in the pre-cancer that we used. Changing constantly. Changing temperature as it were able to get it made a good profile of the nature of the product that you obtain and are different conditions. And the designs you have to deal with those there are cases where you've got messy as of those nonaligned couple nanotubes. Riley in the same run who would get classed as a very poorly formed a carbon nanotubes this would be part of the same fairness. And through time we would then begin to get a sense of. The way all of the regions are specific regions inside the families they produce a particular kind of knowledge of. And by inviting those pattern to as it became possible later on to make a line to tubes and what was a good night out on a date is under the right conditions it was possible to not go down that range. You can look at that he's OK which shows you that. Close to seventy percent of the nanotubes had invaded not a dime would have ranged between fifteen and twenty nine zero meters in very little on either side of the head. And it became possible divided department as in such a way that you regulate the length of the nanotubes. In many cases since this is the last in about forty five minutes we would get about one point four millimeters and so they were quite long and they were quite a lot of the ones in here. If you look at that screen that's one hundred micro meters. I would say that's about seven hundred four point seven millimeters so they are quite a long as well but by controlling the conditions it's possible to very accurately predict what the name of the general name of the nanotubes would be. And. Again by introducing material such. Oxygen containing materials such as either hide the ketones in alcohol and. It was possible. Starting with a spread like that of damage has not only down to a much much more reasonable range by including state in concentrations of. Substances like there was once. And this is a typical result that one obtained from a T.G. a. What we learned out of these was although you can use substances like alcohol and do not regard the damage that range the quality or that there must have been it of the nanotubes suffers in the process as shown by it in the oxidation temperature in the presence of those. The standard run. Is the one that was done without any of those materials. This one of these images were taken for a sample of carbon nanotubes legally impregnated with Pal I.B.M. which we made use of what we use for catalysis. And we able to demonstrate significant a cut and it's a good carbon nanotubes supported on. The label is preparedness is carbon nanotubes. Compatible in most cases then those obtained by using other support such as activated carbon and silicon. What was interesting about some of the cartridges we prepared was they showed an interest in resistance to centering. If you compare the two diagrams. You can see what the particle size generally looks like after that he actually compared to those that were supported in carbon nanotubes which tended to maintain their smaller size. And there wasn't as much since telling of that in that case. We did quite a bit of where the citizens of carbon One is fear is using the same method. Regulator controlling the size by changing the parameters. And impregnating of them with them as well. And using them in the tallis isn't shown. That even with none as far as it's possible to obtain at his number of conversations rates. The current project which uses just to the point of completion. Is one in which we are investigating the change in structure. By preparing this series of compounds or substances in which we have learned that could be the proportions of cobalt and zinc. And we prepared have been proud of all of these and then we do measurements involving the etc and then we measure the optical properties of the material. This way it is not entirely new but what is new use the method you are using to say this out is that. And how while the particle sizes measure particle size is much smaller than previous new previously. And how the transitions range has been shown to be larger than the expected one to one ratio. We have ongoing collaboration without incident. And part of the project that I've been involved with include this in a series of carbon nanotubes colleagues that are in composites what's interesting about colleagues that in molecules is their copyright in shape. And they have extended still. Strains on either side. And if you tear that those two are lined carbon nanotubes. Then you get an interest in our arrangement where you have the cops or the colleagues I didn't want to cure and distributed among the carbon nanotubes and they're proved to be very specific in the nature of the materials that they trap. And therefore if you expose impure water to those materials were found what you get after filtration is materials that they will contain much lower concentrations of Satan Satan particles that are interested in removing. From the water and. Made mention of related applications where. Used to support. Important exchange membranes What does that in a project with mean to have when using such as enhanced senses. There's a clue that the United States only thought about that afterwards it's a universal standard which is a basic low to Cape Town as well. And they are doing. We're calling them to spin and what they're trying to do is to be five years old to make materials or math out of the carbon nanotubes. And in terms of development which sadly was not one that was produced by Michael was involved with in any way is what was in which a group from this university produced what they call in a new tea bag. And a demonstration of this by the professor and was quite interesting because what they showed even on T.V. Was he went over to the muddy as data looking water you can imagine scooped out a class full of the head and then threw a little nono nono material bag contained in a porous material just does this is as you would a tea bag you put it in there should get for a few minutes and then a huge got out of there afterwards and it's virus I've heard he is still alive and kicking. And his claim is they can be used for whatever difficulty did virtually the entire African continent because apparently one of those bags is capable of of beautifier you know up to about ten liters of water. If it really does come off with it. It provides a very quick and expensive way of purifying water and I've mentioned it's one of the key problems that we are trying to address. So we'll see how that one goes. The South African nanotechnology initiative like I said was founded in that about two thousand and three. It's mainly a stakeholder group. It was formed by people who are active in it to be in the field and the researchers and presently has about just over one hundred. Active members there are lots more members in the members group. We see some of them from time to time in conferences but the active core of the group would amount to about a hundred. And they represent which are all the higher education institutions in the country. And its own rules are to stimulate new innovation and like I said to create disengage appear to be in order to encourage and to generate are winners of negative new ideas. And to source fund to encourage new That's the participation in mainly these days. To ensure that there's a focus on their own and it is a bit risk involved with working with different kinds of not immaterial. And promoting the safe use of not immaterial. And. Finding and creating opportunities where in this area. And the activities include pay money to be seen in bold join has begun to Cape Town. As well as producing a monthly newsletter it especially D.C. you know in the South African of this out of South Africa engine of science. An example of what you see and participate in the I was there to see to it. We deny in one setting standards for the characterization of not immaterial as. Organizing the student conferences in symposia. And bringing in scientists from different parts of the world to to give talks on the new technology. And it would be really really difficult to get someone from to attend one of these days to visit become tree and share with us as part of what is happening that this is tradition. At the last conference we had about two hundred ten percent Asians. About forty percent who are from outside the country. The Middle East Europe. East. Mainly China and the rest of the continent and about ten of the presentations were from industry. And were hosting the next one in September this year. So the conclusion is there is some significant activity or not or technology in South Africa it's at the beginning stages of developing but hopefully we will have to make great strides in the years to come this and united group at the T.T.. It is the key ingredient management support and with their two are hoping to go places as well. And what do you hope will happen to us this season if we're going to get a few post dogs from developed countries they need to change since if we can get some of our young scientists to I don't know training that pleases and I'm told that they had that would be absolutely brilliant and that without broadband I will cause a CLI. And finally signed up to be promoting awareness and continuing to mean for me in the development of a coordinated vision undertaken only nanotechnology for the country. And I do thank you for taking your time to attend the talk and I want to then presidents for ensuring that my views it was successful. And I do think the wider community of Georgia for the well card would have been accorded. I've been here for just a day later quite a lot and it's been an absolute pleasure that dealing with everyone. I've made up to this point. And I will go back home and then I was when I came in. Thank you very much. And I'm not sure what people fear I wouldn't mind taking questions about it but I didn't. Maybe a bit of benefit as well from a more in-depth discussion with those individuals who want to discuss a new aspect of my talk so well OK OK but. What good is quite important about basic research is it appears to be a much larger extent. The more established countries. So there's a point to be made for not doing basic research but simply trying to continue on what has been done elsewhere but the problem with Betty is if you don't have the knowledge base to start with then it means there's no peace for the people to cut their teeth on any that way and basically said is unavoidable. And any applied research going to come out of the basic research. So there's a great value in it and is under no difficulty on. That it had been to France France lead from India you don't need to just. It institution is at liberty to make whatever connections it needs. So that's happening quite a lot. I know of one situation that built up their nanotechnology base from virtually nothing by a collaboration with a university in England they said about ten students in the last five years. Most of whom had the R.P. D's already. And because a professor Brian who runs a nanotechnology center. Became a visiting professor he was able to use a bit of time in a regular basis and show his ideas with the students and they have a thriving monetary group as a result of that and years the government is doing is doing quite a bit to fund. To fund collaboration. Which means theoretically I'm not being presumptuous here but if some good were to be reused to be project ahead. The funding for any travel that would happen between the two institutions would mostly be mostly because by the government. The government takes from scientists like I said earlier for not taking good enough care of researchers. But like I said earlier if you think about it. Really. They're much much more serious challenges that cannot be ignored. And so although we don't get as much funding as we wish we had and. I have to are going to the government is doing its behind. Hopefully that will not change or that that will continue and to give you an idea about the amount you are talking about it will sound pitiful. I'm trying to do the conversion from the rare free market it's dollars Now I'll let you do that I'll give you the exchange rate is about seven grains to the dollar at this stage. The nation our Science Foundation or the National Research Foundation allocates about fifty million fifty million South Africans which they have to compete for. And typically. About ten to fifteen projects will get the part of the funds. But through the. It didn't small institutions like the one I'm involved with able to get small pieces of equipment and at least get coverage. And we're hoping that from those smaller From those humble beginnings something more significant will probably in time to in times to come.
