In this talk I will cover the latest advances in nanofabrication and multifunctional surfaces and coatings developed in my group. In particular, I will discuss nanostructured surfaces that possess anti-reflective, superhydrophobic, anti-dew and anti-bacterial properties fabricated in glass, silicon and polymers. I will also discuss how to convert those into efficient solar gain regulating surfaces by coating with phase change oxides (vanadium-dioxide). I will then move to active surfaces based on luminescent solar concentrators that can be used to harvest solar energy and convert it into electricity, while may also act as high data-rate communication channels for transmission of information. I will finally conclude with some examples entailing biomedical devices and applications.

Short Bio
Ioannis Papakonstantinou received his undergraduate degree in Electrical and Computer Engineering from National Technical University of Athens and his PhD in Optical Interconnects from University College London in 2008. In 2008-2009 he worked for Sharp Laboratories of Europe on nanotechnologies for optical displays and between 2009-2011 he was with CERN-European Organisation for Nuclear Research investigating optical fibre communication systems for the Large Hadron Collider. He joined the Department of Electronic and Electrical Engineering at UCL in 2011, where he founded the Photonic Innovations Lab. He is currently Professor of Photonics and Nanofabrication and holder of the European Research Council starting grant IntelGlazing. His group’s core research interests lie on light-matter interactions at the nanoscale.
