The crystal structure of the β-polymorph of metal free phthalocyanine (β-H2Pc) was redetermined from single crystals to obtain precise placements of the hydrogen atoms and a precise model for the X-polymorph (X-H2Pc) for which only limited data fro

Small-angle X-ray scattering (SAXS) and solid state CPMAS l3C NMR were used to describe the crystalline morphology of a series of bacterially produced poly(β-hydroxybutyrate-co-β-hydroxyvalerate) copolymers containing random distributions of 3-hydr

The blends of the water soluble polymers, PEO/HPC and PEO/CMC show crystallization of PEO over a wide composition range. The crystallinity of the PEO fraction decreases drastically beyond an HPC concentration of 70%, whereas it persists throughout th

SAXS and WAXD data were used to establish relationship between the degree of crystallinity, melting temperature and lamellar thickness for the copolymers. It was shown that the predictions of Sanchez and Eby that lamellar thickness increases with bot

Small-angle x-ray scattering (SAXS) and wide-angle x-ray diffraction (WAXD) data are used to establish relationships among the degree of crystallinity, melting temperature and lamellar thickness for random copolymers of poly(β-hydroxybutyrate-co-β-

The possibility of the existence of multiple helices in various homopolysaccharides has been explored by the calculation of conformational-energy contour maps. The structures include homopolymers of d -xylose, d -glucose, d -mannose, and d -galactose
