the behavior of nanoscale energetic materials is quite different from micronsized energetic materials inmany ways. recently, some techniques such as sol-gel method, high speed air impaction and vacuum codeposition have been employed to obtain nanoscale energetic materials. however, only few attentionswere paid to nanoscale energetic materials because of the fabrication difficulty. in this paper...

Phase inversion cellulose acetate propionate membranes showed low permeability to hydrogen peroxide aqueous solutions. Their permeability was increased by alkaline hydrolysis of the ester linking units. However, the permeability remained lower than that of an unsubstituted cellulose membrane. The inclusion of hydroxypropyl cellulose in the membrane formulation, followed by an alkaline hydrolysi...

A new scheme is presented for the preparation of 3~(4-chlorophenyl)5,7-dichloro-l-methylnaphthalene, from which, four derivatives, 3~(4-chlorophenyl)-~-di(n-butyl)aminomethyl~5,7-dichloro-l-naphthalene, ·, methanol hydrochloride, 3-(4-chlorophenyl)-5,7-dichloro-~-(2-piperidyl)1-naphthalenemethanol acetate, l-[3-(4-chlorophenyl)-5,77dichloro-lnaphthyl]-3-di(n-butyl)aminopropanol hydrochloride, a...

The title compound, C(14)H(19)N(3)O(3), was synthesized by the reaction of 3-meth-oxy-propionitrile, tert-butyl bromo-acetate and eth-oxy-methyl-enemalononitrile. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into chains propagating along the b axis.

The aim of this work was to compare hepatocellular toxicity and pharmacological activity of amiodarone (2-n-butyl-3-[3,5 diiodo-4-diethylaminoethoxybenzoyl]-benzofuran; B2-O-Et-N-diethyl) and of eight amiodarone derivatives. Three amiodarone metabolites were studied, namely, mono-N-desethylamiodarone (B2-O-Et-NH-ethyl), di-N-desethylamiodarone (B2-O-Et-NH(2)), and (2-butyl-benzofuran-3-yl)-(4-h...

Distribution coefficients of acetic acid between aqueous phase and solvents (water-C6-C10 alcohols, butyl acetate, ether and benzene) were studied. Synergetic effect was obtained for alcohol and ester systems. A slightly positive deviation was obtained for benzene–ester mixtures. The best distribution coefficient was obtained for hexanol-butyl acetate systems. The coefficients of Redlisch-Kiste...

An exhaustive migration study of eight corks, made ethylene–vinyl acetate, was carried out to identify any non-volatile and volatile compounds using an untargeted approach. The challenge associated with the structural elucidation unknowns undertaken both ultra-high-performance liquid chromatography coupled ion-mobility separation quadrupole-time flight mass spectrometer gas spectrometry. A tota...
