Electrochem. properties of Li+ ion insertion in nanoporous TiO2 (anatase) electrodes were studied by voltammetry. Linear and cyclic potential scans were recorded as a function of electrolyte concn., film thickness, and temp. The currents were directly prop ...
We present the resitivity and structural studies of the melt-spun Al-Mn alloys (with 10-18 at% Mn) that contain more than 50 vol% of the quasicrystalline (qX) Al//4Mn phase. The resistivity varies little with temperature up to approximately 600 K where it ...
Due to their high efficiencies and their potentially low production costs, dye-sensitized solar cells (DSSC) have attracted much attention during the last few years. The technology is based on a layer made of mesoscopic TiO2 film which significantly increa ...
The optical pumping process in IR multiphoton induced unimol. reactions was studied by measuring the pressure dependence of the reaction yield as a function of the laser energy fluence and pulse shape. The dissocn. of SF6 is taken as a model reaction. Rate ...
The methanol dehydration reaction was studied over environmentally benign, easily accessible and inexpensive K10 montmorillonite clay used as the catalyst at a temperature range between 200–700 °C. Nearly 100% selectivity towards dimethyl ether (DME) at 80 ...
Dye-sensitised nanocrystalline solar cells are currently subject of intense research in the framework of renewable energies as a low-cost photovoltaic device. In particular dye-sensitised cells based on spiro-MeOTAD have gained attention as promising appro ...
We study the electrodynamics of a superconductor superlattice consisting of layers of two kinds (wide layers with extremely weak pinning and very thin layers with-strong pinning), in a perpendicular magnetic field. The problem is treated with the nonlocali ...
