Colloidal dispersions of Athabasca asphaltenes in toluene were studied at room temperature by small-angle X-ray scattering (SAXS). Both 5% and 15% dispersions were found to be polydispersed spheres with the main distribution peak at a concentration-independent average radius of 33 A. The main distri

The radius of gyration and "persistence length" of ply-L-alanine, calculated from small-angle x-ray stattering daia, have values of 56 A and 44 1, respectively, in dichloroacetic acid, and 78 A and -30 A in a 1 : 1 v/v mixture of trifluoroacetic acid and trifluoroethanol. This can be interpreted to
Carbon forms different oxides, of which carbon monoxide and carbon dioxide are among the most widely studied chemical compounds. The most stable oxide with more than two cumulative double bonds, known as carbon suboxide C 3 O 2 (1; Scheme 1), was synthesized for the first time nearly 100 years ago.
