Methods for calibration and the preparation of thin sample films are summarized. As an illustrative example, the determination of the sorption enthalpy of hydrogen in a 25 掳C palladium film of 140 nm thickness is discussed in detail. Other examples of the operation of the QCM/HCC are ...
However, hydrogen is highly flammable and explosive hence timely sensitive leak detection is crucial. Existing optical sensing techniques rely on complex instruments, while electrical sensing techniques usually operate at high temperatures and biasing condition. In this paper an on-chip plasmonic–catalytic...
In subject area: Engineering ABE fermentation is an anaerobic fermentation that utilises carbon source to produce solvents (acetone, butanol and ethanol) and its by-products including organic acids (butryric and acetic acid) and gases (hydrogen and carbon dioxide) through the aid of anaerobes, co...
L. Kuznetsov1, E. Liberti3, A. I. Kirkland3, M. S. Alkinani4, H. A. Al-Megren4, J. M. Thomas5 & P. P. Edwards1 Hydrogen is often described as the fuel of the future, especially for application in hydrogen powered fuel-cell vehicles (HFCV's)....
A process is described for removing carbon dioxide from a synthesis gas feed stream in a cryogenic separation plant. In an example described the synthesis gas feed stream () comprises 40 to 65 mole % hydrogen and is fed to a single stage or a first stage of a series of separation stages...
of all the atoms or three quarters of the mass of the universe. It is found in the sun and most stars, and plays an important part in the proton– proton reaction and carbon–nitrogen cycle, which accounts for the energy of the sun and stars. It is thought that hydrogen is a major ...
(2-ethyl-anthraquinone) while forming hydrogen peroxide . A metal palladium or nickel catalyst is used to convert the anthraquinone to the hydroquinone, followed by autooxidation in air to generate hydrogen peroxide. The anthraquinone and hydrogen peroxide are separated; the former is recycled to ...
Endothermic reverse process of dehydrogenation according to the Reaction (1) decreases temperature of the MH leading to decreased rates of H2 evolution; this, in turn, is an additional safety feature of use of the MH, allowing to avoid accidents even in case of rupture of the hydrogen storage...
