Biography:
Prof. Alla Zak, is a Dean of the Faculty of Sciences and Head of the Laboratory for Synthesis and Investigation of Nanomaterials in the Holon Institute of Technology (HIT), Israel. She is also a Scientific Adviser in the Department of Molecular Chemistry and Materials Science in Weizmann Institute of Science (WIS), Israel. Alla Zak is involved in the field of nanoscience and nanotechnology since 1996, including 6 years of Ph.D. study in Weizmann Institute of Science, Israel; 10 years as chief scientist (CSO) in NanoMaterials, Ltd. company and academic research in HIT from 2012. Recently, A. Zak successfully developed the synthesis of WS2 (2009) and MoS2 (2020) nanotubes in pure phase and with perfect crystallinity, that was enigma for many laboratories around the world during 17 and 25 years, respectively. The availability of WS2 nanotubes in significant amounts allows wide investigation of their unique properties during last years.
Currently, the research of A. Zak is focused on fine-tuning of the reaction parameters for preparation of MoS2 INTs, which synthesis so-far possess 100% of 1D morphology with high aspect ratio, but their crystallinity leaves room for improvement. The investigation of MoS2 nanotubes, having mechanical, electrical and optical behaviour superior to that of WS2 INTs, will result in interesting properties and applications in the forthcoming future.
Among the goals of A. Zak’s lab - to study the synthetic routes for nanospheres and nanotubes of transition metal dichalcogenides with modified properties via varying tubes’ diameter, number of layers and layers’ chirality. For example, by doping and intercalation, we hope to get nanotubes with tuneable band gap energy and carrier concentration, towards various electro-optical implementations.
Alla Zak is an inventor of 3 patents and an author of 78 scientific papers.
