In this thesis, first-principles calculations based on density functional theory have been employed to investigate metal hydrogen interaction in transition, p-block and rare earth metals. Furthermore, the accuracy of the stochastic quenching method was tested in describing the structure of amorphous Fe (1-x) Zr x. The investigated systems of transition(More)
Metal hydrides (MHx) provide a promising solution for the requirement to store large amounts of hydrogen in a future hydrogen-based energy system. This requires the design of alloys which allow for a very high H/M ratio. Transition metal hydrides typically have a maximum H/M ratio of 2 and higher ratios can only be obtained in alloys based on rare-earth(More)
Both the Japanese and Hawaiian archipelagos are both completely devoid of petroleum resources. Thus the coauthors of this Editorial live in societies that feel an urgent need to develop alternative energy sources. The utilization of hydrogen as an energy carrier in the form of metal hydrides has long been proposed as a key component in strategies for the(More)
Activated carbon has been synthesized from local palm shell, cardboard and plastics municipal waste in the Kingdom of Saudi Arabia. It exhibits a surface area of 930 m 2 /g and total pore volume of 0.42 cm 3 /g. This pristine activated carbon has been further anchored with nickel, palladium and platinum metal particles by ultrasound-assisted impregnation.(More)
