Amorphous Mg-sulfates: The existence of hydrous Mg-sulfates in martian surface materials has been implied by all landed missions on Mars to date[17], and has been identified by orbital remote sensing (OMEGA and CRISM) [8-10]. Well-controlled laboratory experiments on hydrous sulfates [11-19] provide the fundamental underpinning to link the surface and orbital observations, as well as to address...

In recent years, nanoscale thermal cloaks have received extensive attention from researchers. Amorphization, perforation, and concave are commonly used methods for building cloaks. However, the comparison of three effect different structural proportions on phonon localization not been found. Therefore, in this paper, an asymmetrical structure is constructed to study influence by amorphization, ...

Amorphous alloys are expected to be useful for various applications because they have superior mechanical properties such as strength, hardness and corrosion resistance. So far, the only method production of amorphous metals is quench from liquid state. When materials exposed high-energy ions, lattice structures tend metastable or non-thermally equilibrium, in some cases, lose crystallinity, re...

Kagome lattice offers unique opportunities for the exploration of unusual quantum states correlated electrons. Here, we report on observation superconductivity in a kagome single crystal Pd3P2S8 when semiconducting to metallic transition is driven by pressure. High-pressure resistance measurements show that metallization and are simultaneously observed at about 11 GPa. With increasing pressure,...

Abstract We conducted back-transformation experiments in ringwoodite, bridgmanite, and lingunite at 0.47–8.1 GPa 310–920 °C by situ X-ray observation method. Ringwoodite back-transformed to olivine grain-boundary nucleation growth mechanism. The site saturation occurred the early stage under conditions far from equilibrium boundary, we observed growth-controlled kinetics ringwoodite. determined...
