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 ...
The precise control of the active site environment requires unambiguous binding motifs to enable the incorporation of catalytic active sites, well-adjustable chemical composition with specific functional groups, high surface area with hierarchical porosity for fast mass transfer, and a stable catalyst ...
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...
The extensive use of hydrogen as a fuel has many applications in pollution-free technologies which could be of every-day use in society. Examples are in transportation and power generation; other uses include chemical technology, metallurgy, effluent processing and water production. For mass ...
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...
We quantified the mass loss of SGO related to surface oxygen vacancy formation by thermogravimetric analysis. As depicted in Supplementary Fig. 28, SGO exhibits weight loss during heating, while the weight of SO remains relatively constant in a nitrogen environment. The weight loss of SGO is appro...
While the concentration of benzylamine in the reaction mixture was kept the same, we observed in all cases a strong dependence of δ on the mass of the semiconductor taken for the experiment (Supplementary Discussion 2). The higher the excess of benzylamine per carbon nitride mass, the larger ...
