The calculated Absolute GTP (AGTP) of H2is illustrated as a function of the time-horizon in Fig.1d. The AGTP shows a short-term increase and peaks after 4 years. The AGTP then falls down by several orders of magnitude, in line with the short timescale of the temperature change resp...
Moreover, hydrogen is stored at a temperature close to its phase transition point; hence, any rise in temperature leads to some of the hydrogen evaporating (known as boil-off). This evaporation reduces the system efficiency, consequently creating a significant hazard in unventilated environments [...
in a three-electrode system at room temperature. The geometric area of the CP is 1 cm × 1 cm. A graphite rod electrode and a saturated calomel electrode (SCE) were used as the counter electrode and the reference electrode, respectively. The potential of SCE vs. reversible ...
We review specific-heat and Brillouin-scattering experiments, that have been conducted as a function of temperature on different hydrogen-bonded glasses. Specifically, we have measured the low-temperature specific heat for a set of glassy alcohols: normal and fully-deuterated ethanol, 1- and 2- ...
Product descriptionHydrofluoric acid (HF) is an aqueous solution of hydrogen fluoride gas. At room temperature, it appears as colorless transparent to light yellow smoke liquid with pungent odor. It has a specific gravity of 0.98 which is slightly lighter than water. It has a boiling point of ...

Solid oxide electrolyzers, which operate at much higher temperatures than other electrolysis technologies (650-1000°C), are also being developed. These have the potential advantages of higher efficiency without the use of expensive catalytic materials given their high temperature operation. The elevated...
The static fluctuation approximation (SFA) is used to study the condensate fraction and the specific heat capacity of finite two-dimensional spin-polarized atomic hydrogen. It is found that Bose-Einstein condensation occurs in this system. The transition temperature at different densities decreases as ...
(at.%). The dimension of the cast and as-prepared ingot was 100 × 35 × 8 mm3. To chemically homogenize the as-cast alloy, the ingot was subsequently subjected to a heat-treatment at a temperature of 1200 °C for 24 h in evacuated quartz ampules, then water-...
