Dear colleagues,

You are cordially invited to the BioPhysLab seminar, which will be held on Friday, July 11th 2025 at 13:00h in the library reading room “Dr. Dragan Popović" of the Institute of Physics Belgrade. The talk entitled

"Development of a sensor for extreme conditions using hard x-ray photochemistry"

will be given by Prof. dr. Mike Pravica, Professor of Physics, Department of Physics and Astronomy, University of Nevada, Las Vegas.

Abstract of the talk:

By irradiating oxalate salts with hard x-rays (>7keV), we have created a novel material which we term doped polymeric CO. This novel material is very stable, similar to beer bottle glass, unlike polymeric CO which has been produced by pressurizing CO to more than 5 GPa and decomposes rapidly in a matter of days into graphite and CO2. This novel material still stores CO2 inside it even at high temperature of 500 C over a period of three hours. It has a wide bandgap of 2.5 eVs and is able to produce nonlinear second harmonic generation. Given this information, we propose to create a sensor for extreme conditions of pressure and temperature (e.g. conditions that might exist within a gun barrel or nuclear power plant)) which is already radiation hardened as it was created via irradiation

Sincerely,

--
