Shahar Dery is a PhD student in the Institute of Chemistry at the Hebrew University of Jerusalem. His research focuses on identifying catalytic processes on the surface of metallic nanoparticles. His experiments involve valuable metals for the chemical industry such as platinum, silver and gold. Shahar conducts measurements in particle accelerators using a technique that combines infrared radiation and atomic force microscopy in order to acquire molecular information with a spatial resolution of 20 nanometer. In doing so, more and less reactive locations on the surface of a single particle can be differentiated and mapped. Shahar hopes that the results will provide new insights into the mechanisms of catalytic reactions and on ways to optimize them. Future applications of the study could lead to a reduction in energy consumption and in the use of pollutants in the chemical industry.
