Instructors/Speakers Prof. Qiuling Song College of Materials Science and Engineering Huaqiao University Zoom No.: 97895805410， Password: 072087 Abstract Organoboron compounds are a class of multifunctional reagents for the construction of carbon-carbon and carbon-heteroatom bonds in modern synthetic chemistry. The transformation of organoboron compounds is usually carried out through tetracoordinate boron intermediates, mainly including additions to unsaturated bonds, rearrangements, transmetallations and so on. Although great progress has been achieved on tetracoordinate boron species, there are still shortcomings such as sparse activation modes, paucity of reaction strategies and difficulties on stereoselective control. In the past several years, we have focused on the development of unconventional transformations of organoboron compounds based upon the design of tetracoordinate boron intermediates, including the following three aspects: 1) the ...

Instructors/Speakers Prof. Shuifen Xie College of Materials Science and Engineering, Huaqiao University Zoom No.: 97895805410， Password: 072087 Abstract Exploring active and durable Electrocatalysts is pivotal to the development of green energy conversion technologies, such as fuel cells, water splitting, CO2 reduction et al. Ultrafine 1D multimetallic nanowires are a class of intriguing electrocatalyst candidates, which present unique anisotropic characteristics and superhigh atomic exposures. Precise tuning of their elementa combination and distribution can offer great possibilities to optimize the electrochemical reactivities. In this talk, we focus on atomic-level constructions of precise surface/interface structures on ultrafine 1D multimetallic nanomaterials for electrocatalytic applications. We find that surface heteroatom pairs, oxide/metal inverse interfaces, atomic shell-thickness control as well as amorphous phase are effective strategies for improving ...

Instructors/Speakers Prof. Chengbo Tian College of Materials Science and Engineering, Huaqiao University Zoom No.: 97895805410, Password: 072087 Abstract Perovskite solar cells are promising candidates for next-generation photovoltaic technology due to their low-cost, scalable fabrication and high power conversion efficiency (PCE) above 25% Fullerenes and their derivatives can act as efficient electron transport layers, interfacial modification layers, and trap state passivators in perovskite solar cells, all of which play an important role in increasing efficiency, reducing current hysteresis, and enhancing device stability, Therefore, understanding the relationship between the chemical structures of fullerenes and their photovoltaic properties is the key scientific issues in this field. In this report, we'll introduce the progress of our recent works on the functional fullerene materials and their related ...
