Speaker: Professor David Avnir

Time: 10:00 am, April 16, 2019
Venue:Yizhi Hall (West Campus)


The sol-gel process has opened the possibility of obtaining glasses and ceramics at low temperatures, such that enable the incorporation of organic molecules and metal complexes inside these matrices. Since the library of molecules is very large, the ability to merge any component of this library into glasses, has opened the way to many applications all accross chemistry, physics, materials sciences, and biological secinces. A particular domain that has gained from this ability is the general field of interaction with light, namely optics and photophysics. In the lecture I will describe some contributions we have made to this field. Specific examples include (as time will allow):
* Electrochemical methods for the preparation of optical sol-gel thin films

* Optically transparent, conductive, flexible sol-gel films
* Hybrid polymer/sol-gel submicron luminescent particles
* Core-[sol-gel shell] optical filter sub-micron particles
* Sol-gel optical chemical sensors
* Sol-gel photochromic and light-gate materials
* A sol-gel approach to solar light storgae


David Avnir is a Chemistry Professor at the Hebrew University where he received all his academic education.
His current scientific activities include organically doped metals, theoretical and experimental aspects of chirality, theoretical studies in symmetry, and sol-gel organic hybrid materials and biomaterials. Earlier major interests included fractal theory in chemistry and physics, and far-from-equilibrium phenomena such as chemically driven hydrodynamic instabilities. He has co-authored 380 papers, which are highly cited (ISI: h=63, ~18,000 citations; Scholar: h=78, ~31,000 citations). He was the first Chairman of the Board of the International Sol-Gel Society (ISGS). Some of his recognitions include the Israel Chemical Society Prize (2011), his placement on the Hebrew University's "Wall of the Innovators'' (2012), and receiving the Life Achievement Award of the ISGS (2013).
