Direct ionization processes of hydrogen-like atoms by proton impact are investigated by Born theory. The triple differential cross sections (TDCSs) and the quantities of physical interest in the process are calculated for ionization of H, He + , Li 2+ , and Be 3+ ground-state atoms, using...
A good proton-conducting solid would be a promising material for future hydrogen energy systems. They will be of use as a solid electrolyte for fuel cells, hydrogen production, hydrogen separation, hydrogen sensors, and membrane reactors. Various kinds of proton conducting solids have been synthesize...
Proton transfer refers to the movement of protons (H+) in biological processes such as photosynthesis and respiration, as well as in fuel cells and sensors. It is closely related to hydrogen bonding and can occur along hydrogen-bonded water chains or peptide assemblies, enabling proton conduction...
Protons and neutrons have been shown to be made up of smaller particles and are classified as baryons—particles composed of three elementary units of matter known as quarks. Protons from ionized hydrogen are given high velocities in particle accelerators and are commonly used as projectiles to ...
Combining experimental results and first-principles calculations, we attribute these intriguing properties to the high proton concentration and the well-ordered oxygen vacancy channels granted by the hydrogen-intercalated brownmillerite crystalline structure. Our results open the possibility of using solid ...
5b). Eapp is chosen as Ecollector = −0.5 V vs Ag/AgCl electrodes, which is equivalent to an overpotential of ∼0.2 V vs the standard potential for the hydrogen evolution reaction. While the focus of the SECCM studies is the measurement of proton permeability via Icollector...
However, the proton transport number decreased to 0.52 because the electron-hole current increased along with protonic current according to the defect equilibrium reaction occurring under a wet atmosphere containing oxygen. During operation, the hydrogen evolution rate fluctuates over time by at least ...
In article number 1903871 , Feng‐Yuan Zhang and co‐workers report an innovative electrode design which features mesoporous nanolayer catalysts that significantly augment the accessible electrochemical reaction sites and catalyst utilization for water splitting and hydrogen production. The multilayer‐electrode...
The variation of the proton chemical shifts due to the formation intermolecular hydrogen bonds is computed for a number of complexes which can be formed between the bases of the nucleic acids. The shifts expected for the isolated base pairs, in particular for the G-N1 H, T(or U)-N3H pro...
