Abstract

This is a student seminar (from the group of Ilana Bar).
The seminar will be given in Hebrew.
Abstract: Nanoparticles (NPs) and nanomaterials attract much attention due to their structural diversities, high surface areas and nanoscale sizes, which lead to unique physical and chemical properties. Motivated by NPs functionality and purity demands in various applications, pulsed laser ablation/irradiation in liquid (PLAL/PLIL) were discovered as promising¬ simple approaches, gradually becoming irreplaceable techniques. In this seminar I will focus on two sets of experiments that investigated alloying of colloidal suspensions of mixtures of copper and palladium by collimated and focused beams and the development of a new simple strategy for enhancing NPs production by ablation, which faces one of the major challenges in PLAL. The resulting NPs were characterized by state-of-the-art methods and were used together with the results of the particle heating–melting–evaporation model to control and interpret their characteristics.
