As a key precursor for the formation of new particles, sulfuric acid (H2SO4) plays an important role in the formation of aerosols and clouds in the atmosphere. Gas-phase sulfuric acid molecules can easily form molecular clusters at the beginning of nucleation through hydrogen bonding and other interactions. Therefore, study on the structure and spectroscopy of H2SO4 and the sulfuric acid–water clusters is of great significance for revealing the nucleation mechanism of new particles.
Recently, the group of professor ZHANG Yongsheng, working in the research laboratory of computational materials science at the Institute of Solid State Physics, Hefei Institutes of Physical Science, identified the orbital characteristic of conduction band edges in their new research, which provided novel insights into further thermoelectric enhancement of half-Heusler materials through.
A huge plume of ash, steam and gas rising up high from the underwater near Tonga has captured attention around the world on January 14 just two weeks later from the beginning of 2022. The communication to the outer world has been cut off immediately after the volcano eruption, the devastating explosion was still captured by the satellite orbiting the earth. The explosion may not be the one impacting the planet the most, “but to witness it with the modern array of instruments we have is truly unprecedented”, just as Lori Dengler said, an emeritus professor of geophysics at Humboldt State University in California.
Smart Machining Systems: Modelling, Monitoring and Informatics, an English monograph written by Professor ZHU Kunpeng from Hefei Institutes of Physical Science, Chinese Academy of Sciences (CAS),was published in January, 2022 by Springer.
In 2014, a theory showed that the electronic structure of iron-based superconductor has topological properties due to the multi-orbit characteristics under certain conditions, which is similar to the case in topological insulator. Science then, the subsequent theoretical and experimental studies on topological matter in iron-based superconductors have progressed rapidly. Recently, new progresses have been achieved in measuring the response of the topological defects (single iron impurity, linear defects and magnetic flux vortices)
