The volumetric mass transfer coefficient of hydrogen for the systems of hydrogen-methane-tetralin and hydrogen-ethane-tetralin at temperatures up to 650 K and pressures to 7 MPa were studied. Experiments were carried out using an automated hydrogen probe. The volumetric mass transfer coefficient ...
The energy transfer and storage processes in our cellular power stations were comprehensively understood by careful electron and mass balance analyses of the redox species involved in energy conversion. Owing to the dual function of the platinum in catalyzing both the hydrogen evolution and the oxygen...
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...
and functional features of various mechanoreceptor cells (e.g., Merkel cells, Meissner’s corpuscles, Pacinian corpuscles) found in human skin. Although natural skin mechanoreceptors vary in shape and structure, they share some common structural (i.e., existence of plasma membrane, ion channels)...

In some cases, e.g. operation at low temperatures, or in presence of gaseous impurities in hydrogen gas, kinetic factors may become decisive [48]. Thus, heat-and-mass transfer modelling of H2 charge/discharge flow rates in the MH should incorporate a reliable and verified kinetic expression ...

As displayed in Fig. 7, a Ru SAC with the Ru1-N4 configuration anchored on nitrogen-carbon support displayed an exceptionally intrinsic activity, the mass activity could reach 3571 A gmetal−1 and a high turnover frequency of 3348 O2 h−1, as well as a low overpotential [60]. More...
Hydrogen, which has the highest naturally-occurring phonon frequencies due to its low mass, could be the best candidate material for high-temperature superconductivity4,5. Although the realization of superconductivity in pure hydrogen has been hindered by the extreme pressures required to reach the ...
△1 (△2) in the inset of Fig. 1, the inclusion of the vibrational free energies does not alter the phase transition sequence, but shift down the two transition points in pressure (see explanation later). It is worth noting that the small proton mass may induce significant quantum ...
