An ideal Weyl semimetal with high tunability is an undoubtedly important platform for realizing and manipulating exotic quantum properties of topological semimetals. Currently, all the existing nonmagnetic Weyl semimetals are not ideal and out of external control, namely, no couplings to an order parameter. In this work, we report with a topological phase transition diagram the successful ...

Mar 27, 2019 · As climate change becomes increasingly evident, reducing greenhouse gases including CO2 has received growing attention.

Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery metal that characteristically has a faint yellow hue. Tin is soft enough to be cut with little force. When a bar of tin is bent, the so-called "tin cry" can be heard as a result of twinning in tin crystals; this trait is shared by indium, cadmium, zinc, and frozen mercury.

There is a phase transition between Bi and Bi 2 O 3 accompanying the disappearance of peaks associated with Sb. This is owing to that antimony oxides can dissolve in the strong alkali electrolyte to form SbO 3 − and SbO 2 −. Continuing charging to 1.7 V, only pure Bi 2 O 3 phase is identified.
