A hydride ion in solid-state matter consists of a proton with two loosely bound electrons and holds promise as a fast charge carrier due to its small mass and high polarizability (or anion softness). Verbraeken et al. synthesized BaH2as the first hydride ion conductor,49and the material ha...
However, because hydrogen has a low atomic mass, it is extremely challenging to detect by most analytical methods. In recent years, cryogenic-transfer atom probe tomography (APT) of electrochemically-deuterium-charged steels has provided invaluable qualitative analysis of nanoscale deuterium traps such ...
(with a low atomic mass) in the Fe matrix (with a high atomic mass) are not resolvable in our imaging condition (using 300 kV for electron acceleration). Moiré fringes, sometimes seen in conventional high-resolution TEM images of metal carbides27,28, are absent in these STEM images ...
In addition, the Rh/GDY (274.6 A mgRh–1) exhibits a higher mass activity than that of Rh (62.3 A mgRh–1) at an overpotential of 50 mV (Supplementary Fig. 19; Supplementary Table 6). The Nyquist plots were measured and fitted to a R(QR)(QR) equivalent circuit containing...
Massardo Pages 2105-2116 Article preview Abstract Abstract This paper aims to present a thermo-economic approach for methanol production comparing different renewable energy sources. In this study, the methanol is produced from the CO2 hydrogenation in a pressurized reactor; two different plant ...
Hydrogen is a type of clean energy which has the potential to replace the fossil energy for transportation, domestic and industrial applications. To expand
"We recognize the automakers can't keep paying for fuel, and we see the line of sight to get there, but it is a volume game and we need to hit a critical mass," said Shane Stephens, principal and chief development officer at FirstElement Fuel, which runs 19 of the 39 hydrogen refuel...
A device that can detect the concentration of hydrogen in the presence of other gases would have multiple uses in, inter alia, the transportation industry. For example, in the space program, a mass spectrometer is employed to detect the presence of hydrogen in and around the space shuttle. Th...
Porous nanomaterials (photocatalysts) generally outperform nonporous counterparts, both in environmental and energy applications [128]. This is due to their large specific surface areas and the presence of numerous pores, which enable efficient mass capture and diffusion, leading to enhanced photocatalytic...
Meanwhile, the well-defined pore structure of the CNs can not only prevent the aggregation, decomposition, and coalescence of Pd–Ru alloyed nanoparticles, but also offer electron transfer and mass transport pathway for electrocatalytic reactions [37,64]; Finally, the interaction between the Pd–...
