Cu2ZnSnS4 films with Cu-poor composition prepared by spin coating from a nontoxic methanol-based solution: the effect of annealing temperature

Journal of Asian Ceramic Societies, 2020
In comparison with the stoichiometry and Zn-rich/Cu-poor compositions of Cu2ZnSnS4 (CZTS) photovoltaic material, the properties of Cu-poor films have not been explored adequately.

The Electrical Properties of Tb-Doped CaF2 Nanoparticles under High Pressure

Crystals, 2018
The high-pressure transport behavior of CaF2 nanoparticles with 3 mol% Tb concentrations was studied by alternate-current impedance measurement. All of the electrical parameters vary abnormally at approximately 10.76 GPa, corresponding to the fluorite ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
