Erythritol ((2R,3S)-butane-1,2,3,4-tetraol) is a sugar alcohol (or polyol) that has been approved for use as a food additive in the United States and throughout much of the world. It was discovered in 1848 by Scottish chemist John Stenhouse. It occurs naturally in some fruit and fermented foods ... Read more

Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, ethylene cracking tar, and a small amount from vegetable oil. Carbon black is a form ... Read more

Cholesterol, from the Ancient Greek chole- (bile) and stereos (solid) followed by the chemical suffix -ol for an alcohol, is an organic molecule. It is a sterol (or modified steroid), a lipid molecule and is biosynthesized by all animal cells because it is an essential structural component of ... Read more

Aluminium powder is powdered aluminium. This was originally produced by mechanical means using a stamp mill to create flakes. Subsequently, a process of spraying molten aluminium to create a powder of droplets was developed by E. J. Hall in the 1920s. The resulting powder might then be processed ... Read more

Polyurea is a type of elastomer that is derived from the reaction product of an isocyanate component and a synthetic resin blend component through step-growth polymerization. The isocyanate can be aromatic or aliphatic in nature. It can be monomer, polymer, or any variant reaction of isocyanates ... Read more

The-amino group often participates in hydrogen bonding and as a general base in catalysis. (The?-amino group (NH3+) is attached to the fifth carbon beginning from the?-carbon, which is attached to the carboxyl (C=OOH) group.)

Lysine is an amino acid (building block of protein). It ... Read more

A lubricant is a substance introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces. The property ... Read more

Copper powder is finely granulated copper that has many metallurgic functions. The powder is cheaper than regular cast copper, so engineers can save money on supplies, and it often helps conserve materials because less copper will be needed. Copper powder also can be made to have different ... Read more
