Hydrogen storage capacities have been studied on newly designed three-dimensional pillared boron nitride (PBN) and pillared graphene boron nitride (PGBN). We propose these novel materials based on the covalent connection of BNNTs and graphene sheets, which enhance the surface and free volume for storage within the nanomaterial and increase the gravimetric and volumetric hydrogen uptake capaciti...

We present accurate ground-state energies for the positronium atom in a Coulomb field of point charge Z (XPs!, for the positronium hydrogen ~HPs! and positronium lithium ~LiPs! atoms. Calculations are done using the diffusion quantum Monte Carlo ~DQMC! method. For XPs, the critical value of Z for binding is examined. While HPs is stable, the results show that LiPs is unstable against dissociati...

Abstract: the competition between the precipitation of cobalt ions and evolution of hydrogen gas on the cathode surface duringthe reduction process in a sulfate bath, investigation on the mechanism of metal precipitation is of great importance.In the present work, study on the kinetics of cobalt electrowinning and the mechanism of the involved reactions havebeen carried out. The obtained result...

Traditional transportation fuel, petroleum, is limited and nonrenewable, and it also causes pollutions. Hydrogen is considered one of the best alternative fuels for transportation. The key issue for using hydrogen as fuel for transportation is hydrogen storage. Lithium nitride (Li3N) is an important material which can be used for hydrogen storage. The decompositions of lithium amide (LiNH2) and...

Hydrogen, electric energy production, and metal toxic bioremediation are some of the biotechnological applications sulfate-reducing organisms, which potentially depend on sulfide produced. In this study, offshore Yucatan, capacity to produce hydrogen using microbial consortia from marine sediment (SC469, PD102, SD636) in batch reactors was evaluated. Kinetic tests were characterized by lactate ...
