Enhanced dissolution rate of tadalafil nanoparticles prepared by sonoprecipitation technique: optimization and physicochemical investigation

Nanocrystals of tadalafil, a poorly water-soluble drug, were successfully prepared by sonoprecipitation technique for improving the solubility and dissolution rate. Tween80 was selected as an efficient surfactant to inhibit aggregation in stabilization of drug nanocrystals. Response surface methodology based on central composite design (CCD) was utilized to evaluate the formulation factors affe...

Enhanced magnetoresistance in Ag-doped granular La2Õ3Sr1Õ3MnO3 thin films prepared by dual-beam pulsed-laser deposition

In this article, we report our investigations on the doping effect metallic Ag on the intergrain magnetoresistance phenomenon. La2/3Sr1/3MnO3 ~LSMO! thin films with Ag doping were prepared on ~001! LaAlO3 at different substrate temperatures (Ts) by the dual-beam pulsed-laser deposition technique. Grown at Ts5750 °C, the films are perfectly epitaxial with their c axis perpendicular to the film s...

GRANULAR YBaCuO FILMS PREPARED BY METALORGANIC CHEMICAL AEROSOL DEPOSITION TECHNOLOGY

Fine-grain thin superconducting films can be prepared by metalorganic Chemical Aerosol Deposition Technology (CADT). In this paper, we present the preparation and properties of YBa2Cu307_ x films on the different substrates, Si and SrTiO 3 (100). It is shown that the zero-resistance temperature (Tc,0) of the films on SrTiO 3 substrates is about 90 K, and the critical current density (Jc) at 77 ...
