Next up with Zeou Dou speaking on "Selective Ion Separation for Sustainable Agriculture". Phosphorus is an essential nutrient elements for life, is required to produce DNA. You can find it in every single cell in your body. Your cells depend on it to store and transfer energy. We're taking this neutron every day from food grown by our farmers using fertilizers containing phosphorus. However, over the past century, we've been extensively mining phosphorus from the Earth and it has disrupted the natural cycle, leading to a dwindling phosphorus supply. This continues our long-term food security, etc. Risk. Moreover, overfull realization accelerates the loss of phosphorus into surface waters, causing problems like electrification that decimates aquatic ecosystems and kill fishes. So we have this limited supply and excessive waste. What do we do? We can recycle it. But the current recovery processes based on precipitation, phase two major problems. First, a large amount of chemical input is required to recover the dilute phosphorus due to the low efficiency. And it makes the overall recovery less economically viable than phosphate mining. Second, toxic impurities like heavy metals co co precipitate with phosphorus, leading to a desk up. Sorry. So precipitate with phosphorus. Grazing safety concerns if applied in the soil as fertilizer. So my research comes in to tackle both problems through selective separation. We have developed this functionalize the hydrophilic polymer network to separate nitro NIM from wastewater and to achieve the concentrated nutrient string. And meanwhile, due to the tunable selectivity, we can remove those toxic heavy metals at the same time. So essentially we have made the smart filter to remove the impurities while living behind valuable nutrients. So after the enrichment and purification, with these nutrient string ready to be totally cycle back into food production. Than the beauty of this process is that prints the fixed osmotic pressure inside the polymer, drawing water through the network, the separation process is actually self-driven a suppose the traditional futures from systems. So by using the smart filter, we doubled the phosphorus concentration in the feed solution with a super high recovery efficiency of 95%. On top of that, 100 percent of heavy metal was removed at the same time. Looking forward, we're trying to modify the polymer structure to expand the target to other valuable resources in wastewater. With that, I hope my research with not only close the loop for phosphorus, but also facilitate resource recovery across all major industry sectors driving a sustainable society. Thank you.
