SeO4, SO4, PO4) that are linked to one another solely by hydrogen bonds. At ambient temperatures, the rigid hydrogen-bonding network in such materials results in moderate proton conductivities (~10–5S/cm).8,18In a subset of compounds in this class, the material...
(c) Enlarged and simulated images of the white dashed line region in b and the EELS spectra obtained at the site A and B via line scan. (d) SEM images of V-doped MoS2 nanosheets (V0.05Mo0.95S2). The insets illustrate the nanosheets grown on carbon fibres. (e) TEM image of V0.05...
Mg-based hydrogen storage alloys are a very promising hydrogen storage material in terms of mass and bulk hydrogen storage density, safety, stability and convenience, and very much in line with the specifications for in-vehicle use. However, MgH2 has been limited by high thermodynamic stability,...
The use of hydrogen as a clean and renewable alternative to fossil fuels requires a suite of flammability mitigating technologies, particularly robust sensors for hydrogen leak detection and concentration monitoring. To this end, we have developed a class of lightweight optical hydrogen sensors based o...
A multichannel scaler records the arrival time to obtain the time-of-flight distributions, which we convert to energy spectra by applying the appropriate Jacobians. The detector is rotatable in the plane defined by the incident H atom beam and the surface normal allowing time-of-flight ...
Hydrogen storage level at 12 bar is quite similar to the isothermal experiment at 300 °C/26 bar presented above, but lower than at 350 °C/26 bar. Dehydriding reaction is presented in Figure 4b. For comparison, isothermal dehydriding at 350 °C/0.8 bar (red line of Figure 3) and at...
Line markers are shown as eye-guides; the ∼1070 cm−1−1 band was observed also on Pt and could be related to (H33O++)adad [26,27,28,29]. Figure 5. Dependence of the SERS spectra from the black-CuO electrode upon the potential in 0.1 M KOH solution in water H22O (a)...
They are the source of the 21-cm hydrogen line at 1420 MHz that is detected in order to probe primordial hydrogen.[93] The large amount of neutral hydrogen found in the damped Lyman-alpha systems is thought to dominate the cosmological baryonic density of the universe up to a redshift of...

line 50) should be a saturated sulfur solution such that sulfur will begin to precipitate immediately after the solution is subjected to electrolysis. Because the electrolysis in anodic compartment 42 produces more crystalline sulfur than that included in the passed charge (indicated by line 50), ...
