We calculate the PMV of several ethylene glycol derivatives, in particular, alkyl polyoxyethylene ethers H(CH2)(m-1) (CH2OCH2)(n)CH2OH commonly known as CmEn nonionic surfactants, in aqueous solution at infinite dilution by using the Kirkwood-Buff (KB) equation and the three-dimensional ...
water ,ethylene glycol,or other liquid not classified as hazrdous,They can be wired to energize one device or powered from the same source when liquid flow either exceeds or drops below the set flow rate. The rate of flow can be ajsutable and it is stable. Liquid temp...

Click chemistry approach to functionalize two-dimensional macromolecules of graphene oxide nanosheets A facile "click chemistry" approach to functionalize 2D macromolecules of graphene oxide nanosheets with poly (ethylene glycol) of different molecular weig... K Liang,H He,G Chao - 《纳微快报(英文)》...
Liposomes containing synthetic lipid derivatives of poly(ethylene glycol) show prolonged circulation half-lives in vivo. Novel synthetic lipid derivatives of poly(ethylene glycol) (PEG) have been synthesized and tested for their ability to decrease uptake of liposomes into th... TM Allen,C Hansen,...
N -( tert -butyloxycarbonyl)- d -allylglycine ( 2 ) and N -(benzyloxycarbonyl)- l -allylglycine ( 4 ) were esterified to ethylene glycol and cyclized via olefin metathesis to a protected derivative 7 of 2,7-diaminosuberic acid. Analogous linking of propane-1,3-diol with 2 and ...
