Molybdenum rhenium alloy thin films can exhibit superconductivity up to critical temperatures of T(c)=15K. At the same time, the films are highly stable in the high-temperature methane/hydrogen atmosphere typically required to grow single wall carbon nanotubes. We characterize molybdenum rhenium alloy films deposited via simultaneous sputtering from two sources, with respect to their compositio...

In this study we have investigated the influence of hydrogen intercalation on the local atomic structure of rhenium trioxide using a new approach to EXAFS data analysis, based on the evolutionary algorithm (EA). The proposed EA-EXAFS method is an extension of the conventional reverse Monte Carlo approach but is computationally more efficient. It allows one to perform accurate analysis of EXAFS ...

fac-[Re(CO)3(dppz)] complexes of amido ligands generated in situ under basic conditions display an intense (ε = 16460 L mol-1 cm-1) absorption band between 500-700 nm which are assigned to an n(amido,RNH-) → π* (dppz) inter-ligand charge transfer band offering an extraordinarily low energy charge separating absorption with potential for imaging and energy application.

Small holes are drilled in diamond anvil cell gaskets to contain and pressurize samples. As high-pressure technology pushes the multimegabar regime, smaller-tipped diamond anvils are being increasingly utilized. Consequently, well-centered holes with diameters smaller than 100 pm need to be routinely produced in these gaskets made of exceedingly hard metals. We describe the construction of an i...
