Descripción general

An oligomer of polyethylene glycol, tetra (ethylene glycol) (TEG) is a transparent, colorless, odorless, low volatility, hygroscopic liquid soluble in ethyl alcohol and very soluble in water.

Aplicación

Used for the synthesis of tetraethylene glycol metha acrylate monomer.

Glow discharge plasma deposition of TEG renders surfaces resistant to protein adsorption and cellular attachment.

Precaución

Do not confuse with glycofurol, which is also sometimes called tetraglycol.

Copper nitride particles have a low decomposition temperature, they absorb light, and are oxidation-resistant, making them potentially useful for the development of novel wiring inks for printing circuit boards by means of intense pulsed light (IPL) sintering at low-energy. Here

Significant, otherwise-unavailable information about mechanisms and transition states (TS) of protein folding and binding is obtained from solute effects on rate constants. Here we characterize TS for lac repressor(R)-lac operator(O) binding by analyzing effects of RO-stabilizing and RO-destabilizing solutes on
