Researchers from the Institute of Solid State Physics, Hefei Institutes of Physical Science (HFIPS) along with their Canadian partners from McGill University, developed a new theoretical model recently, which enables accurate predictions of nanovoid structures and energetics in metals.
Hydrodeoxygenation is a common way to reduce the oxygen content of biomass fuel. Compared with direct hydrogenation, transfer hydrogenation is safer and cheaper, as it uses a protic solvent as hydrogen source, thus avoiding the use of high pressurized hydrogen. Recently, the team of Center for Environmental and Energy Nanomaterials, Institute of Solid State Physics, Chinese Academy of Sciences, has made new progress in the study of the effect of metal support strong interaction (SMSI) on catalytic performance. They synthesized Cu/SiO2 and Cu/CeO2 catalysts respectively, and studied the effects of the SMSI effect between copper and metal oxide support or inert support on the hydrogenation of unsaturated aldehydes.
The high confinement regime (H-mode) in the tokamak has been accompanied by a MHD (magnetohydrodynamic) instability labeled edge-localized-modes (ELMs). Present researches on ELM control mostly aims at reducing the heat or particle flux. Nevertheless it is not yet clear about the W sputtering process by the ELM heat and particle flux as well as the effects of ELM control on W sputtering erosion. That will bring an uncertainty to both the control of W impurity source and the evaluation on the divertor lifetime.
Creating an efficient fusion plasma in a tokamak requires balancing competing temperature needs of the plasma – extremely hot in the core to allow fusion to occur but cool enough at the edge not to damage the walls of the device. An international team of researchers at the DIII-D National Fusion Facility has developed an innovative solution to this challenge that uses active injection of gases to cool the plasma in the edge region of an advanced tokamak plasma, reducing the heat before it reaches the walls of the tokamak. Even better, they have done this while maintaining high plasma performance in the core region.
Recently, a research group led by Prof. ZHANG Haimin from the Institute of Solid State Physics, Hefei Institute of Physical Science (HFIPS) reported a highly efficient electrocatalyst for oxygen evolution reaction by in situ generation and systematically illustrated the origin of its excellent performance, which provided a new method for exploiting excellent OER catalysts.
