Lecture topic: Optical methods used in hematology

Abstract: Different optical equipment such as: microscopy, flow cytometry is widely used in investigating blood cells biology and pathology, in medical laboratories and clinics, providing the physicians with a powerful tool in their work. During the lecture some optical methods (flow cytometry, nanoparticle tracking analysis, TEM) will be presented, which are used in research and in daily routine practice, when dealing with blood cancers and anemic patients.

He has also earned a B.S. degree in Pharmaceutical chemistry from Hebei University. In 2018 he was selected as a highly cited researcher in the field of cross-field by Clarivate Analytics. Three years earlier he was awarded the “Thousand Talent Program” Young Outstanding Scientist Grant by the Organization Department of the Central Committee.

Dr Dachi Yang
Institute of Solid State Physics

Dr Dachi Yang attained a PhD degree in Materials Physics and Chemistry from the Institute of Solid State Physics, CAS, China and a Bachelor degree in Materials Science and Engineering from Zhengzhou University, China. In 2014 he has received the “Thousand Talent Program” Young Outstanding Scientist of Tianjin City which was granted by Tianjin Science and Technology Commission. Dr Yang is engaged in the design and preparation of a functional nanomaterial. He took part in developing high performance sensors based on nanomaterials such as intelligent gas sensors (focusing on hydrogen, inorganic gases, VOC gas detection, etc.) in the fields of Internet of Things, human health, home life, industrial production. He was exploring new hydrogen energy conversion (fuel-cell electrode catalysis, electrochemical hydrogen evolution and oxygen evolution) and energy storage (supercapacitor).

Topic: Improving the Stability of Palladium-Based Hydrogen Sensors Working at Low- Temperature

Abstract: The stability of hydrogen sensors is of great importance to devices working over a wide temperature range such as those in aerospace crafts working in low temperature environment. For conventional bulk Pd and Pd nanowires, the instability in both sensor baseline drafting and recently reported temperature-driven “reverse sensing behavior” is still limiting factors for the applications. To enhance the stability in material perspectives, we developed superlattice-structured palladium and other metallic nanowires (such as PdCu, PdBi, PdCo NWs) with random-gapped, screw-threaded, and spiral shapes achieved by wet-chemical approaches. Sensors built with these modified NWs show lower critical temperature (259.4K and 261K) for the “reverse sensing behavior” than those with pure Pd NWs (287K). Moreover, response and the recovery time of the PdCu NWs sensor were of ~9 and ~7 times faster than those of the Pd NWs ones, respectively. To further enhance both the stability and sensitivity, we have developed porous NWs, and porous NWs with spiral and meshy topologies. Immediate benefits are demonstrated in hydrogen sensors as examples, we observed that hydrogen concentrations as low as 0.2% (v/v) were detected, the critical temperatures of “reverse sensing behavior” as low as 239.9K were measured, and better baseline- stability was confirmed compared with those fabricated with pure Pd NWs.

Topic: Superconductivity and superconductors. The promise for a future?
Abstract:The compounds in which electrical resistance suddenly disappears and magnetic field is expelled from the material (below certain temperature) are called superconductors. Superconductivity in Hg was discovered more than 100 years ago, and although we know hundreds of superconducting compounds, this phenomenon remains a hot topic in solid state chemistry and physics. 
In this lecture I will go through the history of superconductivity. Will show you several examples of superconducting materials and a way they were discovered. Finally, I will try to convince you that superconductivity remains the promise for a future.
