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...
the number of hydrogen-bonded interactions is small, which causes the remaining hydrogen bonds to be shortened and tightened. The result is an increased average hydrogen bond energy, which leads to a reduced rate of the bond breaking–forming processes necessary for structural diffusion in the Grott...
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...
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...
where A-H⋯B is a hydrogen-bonded complex and A−⋯H-B+is an ionic pair, bound mainly by the Coulombic attraction between the charges. Proton transfer requires breaking of the chemical bond, a highlyenergetictransition compared to energies ofhydrogen bonds. Therefore, the proton transfer ...
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 ...
A technique for injecting protons directly from a hydrogen-saturated palladium-black electrode into a solid sample is described, together with the associated apparatus that may be used to measure protonic conductivity as a function of sample hydration. This technique is considered to be particularly us...

After one of these collisions, if the kinetic energy of the antiproton is similar to the electron binding energy, it can be captured by the residual Coulomb potential into a bound antiprotonic orbit [75]. The principal quantum number of the captured antiproton np¯ scales with the principal...
moment (the polarization is aligned with one of the hydronium hydrogen bonds), since this is the component responsible for the largest response of the core O–H stretch modes. Freezing specific coordinates is achieved by removing all differential operators of a frozen coordinate from the Hamiltonian...
