The orientational distribution function of the nematic phase of suspensions of the semiflexible rodlike virus fd is measured by x-ray diffraction as a function of concentration and ionic strength. X-ray diffraction from a single-domain nematic phase of fd is influenced by interparticle correlations at low angle, while only intraparticle scatter contributes(More)
We have measured and analyzed optical absorption and x-ray absorption spectra of CdS nanocrystals grown by solid-state reaction in a borosilicate glass, with average crystallite radii from 1.4 to 5 nm. The first (CdS) and second (Cd-Cd) neighbor distances are within 0.2% of the bulk values in al l cases. We establish an upper bound for the interfacial(More)
High-purity and homogeneous YBa2Cu3Oy single crystals with carrier doping level near the AFM-SC boundary have been obtained in the oxygen content range between y = 6.340 and 6.370. The crystals are ortho-II phase at room temperature and undergo the orthorhombic to tetragonal transition at about 140°C. They show sharp superconducting transitions, with Tc(More)
