Recent Progress of TwoDimensional Thermoelectric ...

Jan 23, 2020· TMDCs have gained considerable attention as a potential thermoelectric material in recent years due to their low thermal conductivity (–1 W mK −1) and their large inplane mobility (200–500 cm (Vs) −1). Recently, several theoretical and experimental studies on the thermoelectric performance of TMDCs have been reported.


Sodium fluoride | NaF PubChem

Sodium Fluoride is an inorganic salt of fluoride used topically or in municipal water fluoridation systems to prevent dental caries. Fluoride appears to bind to calcium ions in the hydroxyapatite of surface tooth enamel, preventing corrosion of tooth enamel by acids. This agent may also inhibit acid production by commensal oral bacteria. (NCI04)

Nitroglycerin | C3H5(NO3)3 PubChem

Nitroglycerin is a nitroglycerol that is glycerol in which the hydrogen atoms of all three hydroxy groups are replaced by nitro groups. It acts as a prodrug, releasing nitric oxide to open blood vessels and so alleviate heart pain. It has a role as a vasodilator agent, a nitric oxide donor, an explosive, a prodrug, a tocolytic agent, a muscle relaxant and a xenobiotic.

Antisurge Control | CCC Global

Centrifugal and axial compressors are susceptible to surge which can cause catastrophic damage to your turbomachinery train. The Antisurge controller is one of the most critical turbomachinery control applications that protect a compressor from surge by continuously calculating the distance between the compressor’s operating point and its surge limit line.

Check Valves Comatrol

Check valves allow free flow in one direction and block flow in the opposite direction. Standard check valves, suitable for most applications, have fully guided poppets which always block flow from 2 to 1. They are spring biased closed until sufficient pressure is applied at 1 to open flow to 2. This pressure is commonly called the crack pressure.
