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 ...
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 ...
Future space exploration will emphasize on cost effectiveness and highly focused mission objectives. Missions costs are directly proportional to its total weight, thus, the trend will be to replace bulky and heavy components of space carriers, communicatio ...
Electron traps at the nanostructured TiO2 (anatase)/aq. electrolyte interface were studied by electrochem. methods. The transient current decays at different potentials pos. of the flatband potential clearly illustrate the trap-filling process. The more ne ...
A frequently proposed solution to node misbehavior in mobile ad hoc networks is to use reputation systems. But in ephemeral networks - a new breed of mobile networks where contact times between nodes are short and neighbors change frequently - reputations ...
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 ...
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 ...
