High power solid state laser systems operating in a pulse mode dissipate the transient and excessively large waste heat from the laser diode arrays and gain material. The heat storage option using Phase Change Materials (PCMs) has been considered to manage such peak heat loads not relying on oversized systems for real-time cooling. However, the PCM heat storage systems suffer from the low heat ...

Complex metal hydrides have recently gained interest as solid electrolytes for all-solid-state batteries due to their light weight, easy deformability, and fast ion mobility at elevated temperatures. However, increasing low conductivity room temperature is a prerequisite application. In this review, two strategies enhance in complex hydrides, nanostructuring nanocomposite formation, are highlig...

In the past few years we have developed an array of composite reducing systems based on combinations of tin or silicon hydrides with various transition-metal homogeneous catalysts such as palladium(O), ruthenium(I1) and molybdenum(0) complexes. These represent a useful family of reducing media that effect highly selective reductions of various organic functional groups, such as allylic heterosu...

A safe and efficient method for storing hydrogen is solid state storage through a chemical reaction in metal hydrides. A good amount of research has been conducted on hydrogenation properties of metal hydrides and possible methods to improve them. Background research shows that heat transfer is one of the reaction rate controlling parameters in a metal hydride hydrogen storage system. Consideri...

Chemistry and kinetics of air reactions with plutonium monoxide monohydride (PuOH) and with mixtures of the oxide hydride and plutonium metal are defined by results of pressure-volumetemperature (PVT) measurements. Tests with specimens prepared by total and partial corrosion of plutonium in 0.05 M sodium chloride solution show that reaction of residual water continues to generate H, after liqui...

A method has been developd determine selenium by hydride generation atomic absorption using nitrogen trapping technique. A series of experiments was performed to obtain the optimum condition. The results show that this method has the advantage of being sensitive, accurate, rapid and simple. Transition metal and other hydride forming elements interferences on the determination of selenium was st...

Hydrido complexes, especially of the platinum group metals, have a pivotal role in homogeneous catalysis (1). They appear as intermediates in many catalytic cycles, including hydroformylation, asymmetric hydrogenation, hydroxycarboxylation, and oligomerisation of olefins. In order to perform highly selective hydrido-mediated catalytic reactions it is essential that ligands are present which all...

β-hydride elimination (BHE), the [2 + 2] pericyclic hydride rearrangement, is a well-established process frequently encountered in organometallic reaction mechanisms. BHE is an extraordinarily prevalent reaction mechanism, and it is commonly presented in reports, 8 reviews, 11 and textbooks. 16 Despite its literature precedence, more can be learned about BHE, especially when heteroatoms are inv...
