Flux Pinning Effects of Y2o3 Nanoparticulate Dispersions in Multilayered Ybco Thin Films (postprint)
The flux pinning effects of Y2O3 nanoparticulate inclusions in YBa2Cu3O7 d (Y123 or YBCO) thin films using (Y2O3/Y123) · N multilayer structures were studied. The multilayer films were made with pulsed laser deposition (PLD) on SrTiO3 and LaAlO3 substrates with a Y2O3 nanoparticulate pseudo-layer thickness ranging from 0.2 to 1.4 nm, and YBCO layer thickness varying from 7 to 50 nm. Scanning el...
متن کاملCharacterization of Olanzapine – Solid dispersions.
Aim: To enhance the aqueous solubility of olanzapine by using the Solid dispersion technique. Solid dispersions of Olanzapine were prepared by the dispersion method using using PGS and SSG as carriers. Drug:carrier ratios such as 1:1, 1:2, 1:4, 1:6, 1:8 and 1:10 were tried for optimization. Characterization was done by phase solubility, in vitro release, saturation solubility, permeation, wetta...
متن کاملAnalytical Electron Microscopy for Characterization of Fluid or Semi-Solid Multiphase Systems Containing Nanoparticulate Material
The analysis of nanomaterials in pharmaceutical or cosmetic preparations is an important aspect both in formulation development and quality control of marketed products. Despite the increased popularity of nanoparticulate compounds especially in dermal preparations such as emulsions, methods and protocols of analysis for the characterization of such systems are scarce. This work combines an ori...
متن کاملStructure evolution of nanoparticulate Fe2O3.
The atomic structure and properties of nanoparticulate Fe2O3 are characterized starting from its smallest Fe2O3 building unit through (Fe2O3)n clusters to nanometer-sized Fe2O3 particles. This is achieved by combining global structure optimizations at the density functional theory level, molecular dynamics simulations by employing tailored, ab initio parameterized interatomic potential function...
متن کاملSucrose synthesis of nanoparticulate alumina
The synthesis of nanoparticulate α-Al 2 O 3 at 600 • C using a sucrose-based polymer dispersion technique was reported recently by Das et al. [1]. This is of interest, as γ-Al 2 O 3 is frequently an unwanted intermediate phase in the conversion of nanoparticulate amorphous alu-mina into nanoparticulate α-Al 2 O 3. γ-Al 2 O 3 has a relatively disordered structure, but usually requires temperatur...
