    Cool Photonic and Electronic Plastics for a Greener World
    (Georgia Institute of Technology, 2019-01-22) Stingelin, Natalie
    With seabirds trapped in multipack drink rings, and mid-ocean islands of indestructible rubbish, the idea that plastics could play a big part in a sustainable future world might seem far-fetched. However, new smart photonic and electronic plastics may yet rescue the reputation of this all-consuming 20th century material. Research into such functional plastics for cars and buildings could drastically reduce the need for air conditioning and, thus, improve their energy efficiency. We will present recent efforts to design new plastics of desired photonic and electronic functions targeted for a greener world. One line of our enquiry is to explore the potential of new polymer-based systems that can offer the same flexibility, softness and light weight as commodity plastics but can control the flow of light therefore assisting energy (light) harvesting, e.g., of photovoltaic devices, or light out-coupling from light-emitting diodes. Other opportunities for such systems include photonic heat mirrors that can prevent undesired heat built up of solar cells limiting performance degradation during operation of the cells. Such mirrors also can be exploited to reduce the energy we waste to keep buildings at the temperature we want.

    Electronic Processes and Phenomena in Organic Materials: A Materials Scientist’s Point of View
    (Georgia Institute of Technology, 2013-07-12) Stingelin, Natalie
    In the past decade, significant progress has been made in the fabrication of organic semiconductor thin-film devices predominantly due to important improvements of existing materials and the creation of a wealth of novel compounds. Many challenges, however, still exist. Key to commercial success is to make it technological practice to exploit the touted potential for low-cost manufacturing of these functional materials. This requires intimate knowledge of relevant structure/processing/performance interrelations. Here, examples are given of how materials scientists ‘tools’ may be utilized to gain further understanding of this interesting class of materials and how the physical organization, from the molecular scale to the macroscale, of functional organic matter such as polymer semiconductors can be controlled. To this end, we present a survey on the principles of structure development from the liquid phase of this materials family with focus on how to manipulate their phase transformations and solid-state order to tailor and tune the final ‘morphology’ towards technological and practical applications.

    Going against the grain: the dematurity of the European textile industry
    (Georgia Institute of Technology, 2008) Noor, Fianti ; Peters, Stuart ; Stingelin, Natalie ; Smith, Paul
    The paper investigates the process of transition of the European textile industry away from being a mature industry towards a more knowledge-based one. The European industry has fallen into what Abernathy (1978, 1983) termed the 'maturity trap' due to a number of different factors; firm inertia, the fragmentation of markets, increasing competition and regional and national business cultures. However, the findings also suggest that a number of companies have successfully circumvented maturity-trap and indeed shifted their capabilities from mature businesses to ferment phase. There is now a concerted effort at the EU and national level to rescue the European industry from the maturity trap based on innovation and entrepreneurial management at the level of the firm.
