[1] Methyl chloride concentrations were measured in the upper 200 m of the water column of the NW Atlantic during three cruises along the same track in spring, summer and fall of 2003. Distinct seasonality was apparent, with the surface waters being either undersaturated or close to equilibrium with the atmosphere in spring, but with supersaturation of the warmer waters in summer and fall. Cool...

Glycophorin A and its isolated transmembrane region (GpATM) are each known to form sequence-specific dimers in SDS micelles. Whether this behavior accurately reflects behavior in red cell membranes or lipid bilayers, however, has remained unclear. Resonance energy transfer between labeled GpATM peptides has been used to observe dimerization of GpATM in bilayers. Separate populations of GpATM pe...

Simple, easy to use and selective method of Al(III) sorption-spectroscopic (SS) determination was proposed. For this purpose, silica modified with tridecyloctadecylammonium chloride(SGII) using adsorption technique and glass slide modified with thin silica-poly(dimethyldiallyl-ammonium chloride) (SGI) composite film obtained by sol-gel technique were worked out. It was shown that lumogallion (L...

In the title compound, C7H11Cl2NO, the piperidine ring shows a chair conformation and the bond-angle sum at the N atom is 359.9°. The H atom of the di-chloro-methyl group is in an eclipsed conformation with respect to the carbonyl group (H-C-C=O = -5°). In the crystal, inversion dimers are linked by pairs of C-H⋯O hydrogen bonds between the di-chloro-methyl group and the carbonyl O atom, which ...

In the title thio-phene derivative, C13H18N2O3S, the dihedral angles between the thio-phene ring and the [(di-methyl-amino)-methyl-idene]amino side chain (r.m.s. deviation = 0.009 Å) and the -CO2 ester group are 3.01 (16) and 59.9 (3)°, respectively. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R 2 (2)(16) loops. The dimers are linked by another weak C-H⋯O i...

In the title compound, C(16)H(12)FIO(2)S, the O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane through the benzofuran fragment. The 4-fluoro-phenyl ring is rotated slightly out of the benzofuran plane, as indicated by the dihedral angle of 7.43 (6)°. In the crystal structure, pairs of short I⋯O [3.074 (2) Å] contacts link the mol-ecules into cent...
