Having builtin compression process, monotooth rotary compressor can reach larger discharge pressure with higher efficiency and lower discharge temperature when compared with Roots blower. So it is a good alternative for Roots blower used in various fields. In order to put this kind of compressor into market as soon as possible, theoretical and experimental study of the monotooth rotary compress...

Dual-ion Na–organic batteries were provided with anti-aromatic NiNc, exposing inherent charge–discharge behavior high discharge capacity, durability, and Coulombic efficiency high-density currents.
