“Seven different solvents (methanol, ethanol, 2-propanol, 1,2-dichloroethane, water, chloroform, and dichloromethane) were used to prepare electrospun poly (vinyl pyrrolidone) (PVP) fibers. The dielectric constant, viscosity, and surface tension of the solvents essentially affected the electrospinnability, morphological appearance, and size of the as-spun fibers. Small and
uniform as-spun fibers could be fabricated from PVP solutions in solvents with a significantly high dielectric constant, low surface tension, and low viscosity. In three alcohol solutions (e.g., methanol, ethanol, and 2-propanol), the diameters of as-spun PVP fibers decreased with the dielectric constant, dipole moment, and density of the solvents increasing and with the viscosity of the solvents decreasing. Among these solvents, methanol was the best solvent, providing fibers with
an optimal morphological appearance and a small fiber diameter. Mixing an unspinnable solvent this website with a solvent with a high dielectric constant, low surface tension, and low viscosity could increase the electrospinnability of the solution. The effects of solution properties and spinning conditions on the morphological appearance and diameter of selleck compound electrospun PVP fibers were also carefully investigated. Under all investigated conditions for the electrospinning of a PVP solution in ethanol, the average diameters of the as-spun fibers ranged from 200 nm to 1.5 mu m. Well-aligned
PVP fibers were also produced with a rotating-drum collector technique. Lastly, PVP was used in the fabrication of poly[2-methoxy-5-(2'-ethythexyloxy)-1,4-phenylene-vinylene] and TiO2 fibers by acting as a polymer carrier or guide. (C) 2009 Wiley Periodicals, Inc.

“SnO2 films with a thickness around 150 nm were deposited on the (111) surface of a SrTiO3 single crystal substrate by laser molecular beam epitaxy technique in a temperature range 600-750 degrees C and oxygen pressure from 10(-3) to 1 Pa, respectively. The growth behavior was in situ monitored by reflection high-energy electron diffraction, and the epitaxial relations were further investigated by ex situ x-ray diffraction measurement in different geometries. All the films were confirmed to be highly (200) oriented showing good crystalline quality, despite the large lattice mismatch between SnO2 and SrTiO3. Based on the crystallographic model and structure analysis, six equivalent directions in the SrTiO3 (111) surface for the nucleation of SnO2 were discovered, which confirmed the existence of sixfold symmetrical domains in the SnO2 epilayer.
