DOI: 10.1016/j.mtphys.2020.100267
Abstract: Abstract Enriching electrocatalysts with uncommon definite functions are of great influence but remains extraordinarily challenging. Upon the excellent metallic characteristics of transition metal nitrides (TMN), the unfavorable d-band energy level severely hinders their hydrogen evolution… read more here.

DOI: 10.1021/jacs.2c10884
Abstract: Low-dimensional metal halides exhibit strong structural and electronic anisotropies, making them candidates for accessing unusual electronic properties. Here, we demonstrate pressure-induced quasi-one-dimensional (quasi-1D) metallicity in δ-CsSnI3. With the application of pressure up to 40 GPa,… read more here.
