The compound, Cs 3 CdH 5, prepared by the reaction of caesium hydride, CsH, and cadmium metal powder at high temperature contains the CdH 2− 4 ion, along with caesium cations, Cs +, and hydride anions, H −. The tetrahedral anion is an example of an ionic complex of CdH 2. The average Cd-H bond length in CdH 2− 4 is 182pm.

2-Mercaptoethanol (also β-mercaptoethanol, BME, 2BME, 2-ME or β-met) is the chemical compound with the formula HOCH 2 CH 2 SH. ME or βME, as it is commonly abbreviated, is used to reduce disulfide bonds and can act as a biological antioxidant by scavenging hydroxyl radicals (amongst others). It is widely used because the hydroxyl group ...
Ethylene carbonate (sometimes abbreviated EC) is the organic compound with the formula (CH 2 O) 2 CO. It is classified as the cyclic carbonate ester of ethylene glycol and carbonic acid. At room temperature (25 °C) ethylene carbonate is a transparent crystalline solid, practically odorless and colorless, and somewhat soluble in water.
The computational Diffie–Hellman (CDH) assumption is a computational hardness assumption about the Diffie–Hellman problem. [1] The CDH assumption involves the problem of computing the discrete logarithm in cyclic groups. The CDH problem illustrates the attack of an eavesdropper in the Diffie–Hellman key exchange [2] protocol to obtain the ...
Following the commercial classification of chemicals, chemicals produced by chemical industry can be divided essentially into three broad categories: commodity chemicals: are chemicals produced in large quantities and in general their applications can be traced back to their chemical structure; for this reason, two commodities produced by two ...
