polyethylene glycol boiling point

The solar fluid is a mixture of water propylene and

Propylene glycol (one chemical) (and its very toxic cousin ethylene glycol—car antifreeze) when mixed with water forms a solution which is a relatively good heat transfer fluid When mixed approximarely 50%/50% ( really 60/40) it forms a eutectic

Polyethylene Glycol Density and Length Affects

The prospective cancer therapy applications of inorganic nanoparticles (NPs) have been encouraged by surface modifications with polyethylene glycol (PEG) When grafted at high densities PEG reduces NP surface interaction with its environment hence minimizing its detection by the immune system The drawback of high density PEG surfaces is its reduced uptake by cancer cells
