Electrolysis is the process where an electric current splits water into hydrogen and oxygen. According to Kato et al.[13], hydrogen production bywater electrolysisconsumes the highest amounts of energy. However, it is considered a clean, emission-free process only when the energy used for the ...
While the majority of mechanisms assume a homolytic bond rupture, we recently showed that heterolytic cleavage is also thermodynamically viable. For a cleavage of this type to be feasible, the charge separation created upon breaking of the N–Cα backbone bond must be quickly annihilated. In ...
The shifts expected for the isolated base pairs, in particular for the G-N1 H, T(or U)-N3H protons and the protons of the amino groups of A, G c, when combined with previous computations on the shifts to be expected upon base stacking, may enable a refined analysis of the high ...
Hydrogen plasma refers to a high-energy state of hydrogen gas where the atoms have been ionized, resulting in a collection of protons and electrons that exhibit unique properties such as high energy densities, mean proton energies, and electron densities. AI generated definition based on: Fusion ...
15c,d). These observations clearly indicate the sensitivity of CPHATN-1a to HCl, and interactions between protons and weakly-basic pyrazine moieties of HATN core. Removal of HCl from CPHATN-1a resulted in recover of the original absorption and emission spectra. This is, to our knowledge, the...
Hydrogenase catalyzes the interconversion of hydrogen to protons and electrons. There are three classes of hydrogenase, ie, [NiFe]-hydrogenase, [FeFe]-hydrogenase, and [Fe]-hydrogenase (Vignais et al., 2001). [NiFe]-hydrogenase is found in a variety ofarchaeaand bacteria, and catalyzes hy...
ENDOR studies of the superhyperfine couplings of hydrogen‐bonded protons. IV. Carboxyl radical anions in irradiated glycine and α‐amino isobutyric acid To elucidate the controlling factors for the selective proton transfer from the neighboring NH3 groups to the anion across the hydrogen bridge, the...
The paper reviews the history and present understanding of protons in oxides; their defect chemistry, thermodynamics, and transport. Focus is put on correlations between hydration thermodynamics and other materials properties which may help to predict proton uptake and proton conduction in oxides. Also...
Two chemical species exist in the aqueous solution that are reducible with the potential granted by the photosystem: protons and dioxygen molecules. The two reactions, hydrogen evolution and oxygen reduction, are in competition with formal potentials of -0.41 and -0.33 V (vs. SHE), ...
The blue-light photogenerated electrons from the semiconductor, which were stored in the surface states, were then transferred to the protons to generate hydrogen. Other materials such as TiO2-graphene nanocomposites were also analyzed for photocatalytic performance of hydrogen evolution from water ...
