Hof University of Applied Sciences is always involved in high-level global conferences: The International Conference on Advanced Materials for Societal Applications (ICAMSA-2021) was again hosted this year by J. C. Bose University of Science and Technology, Faridabad (India) from October 26-28, 2021 as an online format. In addition to Indian, US and European universities and institutes, Hof University of Applied Sciences was also represented by Prof. Dr. Nico Behrendt. He was invited as an honorary guest to give a one-hour plenary talk on his former research field of polymer electrets and piezoelectrics.
ICAMSA is a conference at which groundbreaking, future and, above all, socially important technology topics are presented and discussed without setting a technical focus. This results in a very wide range of topics, which makes this conference particularly varied.
Broad spectrum of topics
The conference therefore attracted a large number of interested scientists – at its peak, over 140 online participants followed the conference. Speakers from the University of Twente (Netherlands), the National Physical Laboratory (India), the University of Southern (Denmark), IIT Roorkee (India), the University of New South Wales (Australia), the University of Delhi (India), IIT Mandi (India), the University of Leipzig, Florida Polytechnic University (USA) and other institutes gave presentations on various scientific topics. In addition to studies on semiconductors and superconductors, modifications of battery materials at the atomic level, graphene, rare earth glass ceramics, nickel oxide modified solar cells, photooxidation of ethanol, electrolysis processes and the development of new membrane materials, global challenges such as the generation of “clean energy” were also intensively discussed. The Indian hydrogen program was also presented.
Effects for sensor applications
In his presentation, Nico Behrendt discussed polymer materials with specific cavity structures that exhibit piezoelectric activity after suitable electrical charging. If a mechanical force is applied to such materials, measurable electrical charges are generated in these materials. This effect can be used for various sensor applications. Conceivable applications include, for example, measurements of intraocular pressure in the context of early glaucoma detection, where particularly “soft” sensors are required. In this context, it was particularly gratifying that the lecture was also attended by several scientists and a doctoral student who are also involved in measurement technology with these materials and therefore showed great interest.
India’s immense progress
In his closing speech, Nico Behrendt highlighted India’s immense development in the field of science and technology in recent decades. He has been associated with the Department of Physics at India’s Maulana Azad National Institute of Technology in his field of expertise since 2007, and has therefore been able to observe that India has become an increasingly important nation in solving global challenges such as climate change. Also, the many outstanding Indian scientists now working in the U.S., Europe, or other parts of the world at prestigious universities and institutes are encouraging evidence of India’s strong and positive development in the field of research and academic education
