    Effect of TiO2 sol on the conversion efficiency of TiO2 based dye-sensitized solar cell

    Many approaches such as coupling with narrow bandgap semiconductors, do** with metals, using TiO2/graphene/TiO2 sandwich structure and TiCl4 treatment have been taken to improve TiO2 based dye-sensitized solar ...

    Dynamical Behaviour of Compressible Homogeneous Uniformly Rotating Ellipsoids with Nonparallel Angular Velocity and Vorticity

    The study of nonequilibrium, self-gravitating, compressible, homogeneous and uniformly rotating gaseous ellipsoidal models is extended from parallel to nonparallel angular velocity and vorticity. The different...

    Effects of variations of parallel angular velocity and vorticity on the oscillations of compressible homogeneous rotating ellipsoids

    Earlier work on the oscillations of an ellipsoid is extended to investigate the behaviour of a nonequilibrium compressible homogeneous rotating gaseous ellipsoid, with the components of the velocity field as l...

    Radiation pressure effects in the oscillations of compressible rotating homogeneous spheroids

    Earlier models of compressible, rotating, and homogeneous ellipsoids with gas pressure are generalized to include the presence of radiation pressure. Under the assumptions of a linear velocity field of the flu...
