In this paper, we present some analytical results in the development of the classical Bower theory of Raman scattering in the partially oriented polymers. We consider more general case of arbitrary molecular orientation instead of Bower's assumption

The novel application of ionic liquids as media for radiolytic generation and UV−vis−NIR spectroscopic characterization of radical ions is described. The redox properties of neat 1-butyl-3-methylimidazolium salts and their aqueous solutions have

A polysulfone spinning solution used recently to produce enhanced selectivity gas separation hollow fiber membranes was rheologically assessed using a rotational rheometer and an optical shear cell. Effects of temperature and shear rate on viscosity,

Photolysis of benzotriazole isolated in argon and nitrogen matrices at 12–14 K has been studied by means of UV–visible and IR absorption spectroscopy. Short wavelength irradiation resulted in N–NH bond scission to give diazoimine 3 and minor pr

Polysulfone gas separation hollow fiber membranes were manufactured using a dry/wet spinning process with forced convection in the dry gap. Hollow fibers were produced using two different bore coagulants: one pure water and one with reduced water act

Photolysis of tetrachlorodiazocyclopentadiene (1) in oxygen-saturated hydrocarbon solvents results in the transient formation of tetrachlorocyclopentadienone O-oxide (3). This rapidly decomposes, giving rise to products derived from oxidation of the

Short wavelength UV irradiation of (phenylacetylene)Co 2 (CO) 6 ( 3 ) in argon matrices at 12 K results in loss of CO to form (phenylacetylene)Co 2 (CO) 5 ( 4 ). Reversal of this reaction occurs on longer wavelength irradiation. When the reaction is

Photolysis of 2-nitrobenzyl methyl ether in Ar and N2 matrices at 12 K generated an intermediate with λmax at 430 nm, and which was itself photolabile at 430–460 nm. Matrix IR spectra, as well as the UV-visible absorption, were obtained for this s

Asymmetric polysulfone and polyacrylonitrile flat sheet membranes have been produced by a simple dry-wet casting technique. Both membrane types were cast at low and high shear rate. Molecular orientation in the membranes was determined using polarize
