Significant heat transfer issues associated with four alternative hydrogen storage methods are identified and discussed, with particular emphasis on technologies for vehicle applications. For compressed hydrogen storage, efficient heat transfer during compression and intercooling decreases compression work. In addition, enhanced heat transfer inside the tank during the fueling process can minim...

Hydrogen is recognized as a potential and extremely interesting energy carrier, which can facilitate efficient utilization of unevenly distributed renewable energy. Furthermore, hydrogen has an extremely interesting chemistry and form compounds with most elements in the periodic table and with a variety of different types of bonds. Metal hydrides has recently become very interesting as new clas...

A modern view of the properties chemical elements has confirmed theory hot origin Earth. The next step in developing this was hypothesis initial hydride In work, we attempted to find additional evidence for and show effects that flow from it. effect physical atoms ions on their behavior during formation Earth studied. maximum contribution distribution made by those whose content original protop...

Anodes for Li-ion batteries are primarily carbon-based due to their low cost and long cycle life. However, improvements to the Li capacity of carbon anodes, LiC6 in particular, are necessary to obtain a larger energy density. Stateof-the-art light-metal hydrides for hydrogen storage applications often contain Li and involve reactions requiring Li transport, and light-metal ionic hydrides are ca...

Noble gases are mostly known as inert monatomic gases due to their limited reactivity with other elements. However, the first predictions of noble-gas compounds were suggested by Kossel in 1916, by von Antropoff in 1924, and by Pauling in 1930. It took many decades until the first noble-gas compound, XePtF6, was synthesized by Neil Bartlett in 1962. This was followed by gradual development of t...

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...

Fumigation with phosphine gas is by far the most widely used treatment for the protection of stored grain against insect pests. The development of high-level resistance in insects now threatens its continued use. As there is no suitable chemical to replace phosphine, it is essential to understand the mechanisms of phosphine toxicity to increase the effectiveness of resistance management. Becaus...
