Based on a simple model, we extract spin- and energy-dependent probing depths from experimental polarization spectra. For grazing impact of protons the probing depth strongly depends on the energy of secondary electrons.doi:10.1016/S0039-6028(01)01109-8R. Pfandzelter...
The enzyme is grouped into three classes based on the metal cofactor present at the active site, namely [Fe-Fe], [Ni-Fe] and [Fe] hydrogenases. In general, hydrogenases catalyze the reversible conversion of dihydrogen to protons and electrons through the reaction, H2 ↔ 2H+ + ...
Fe atoms in Fe/Cu-HNG transfer electrons to Cu and slightly reduce Cu as compared to Cu-HNG. Such a trend obtained by the absorption spectra is in agreement with the XPS analyses. The k3- weighted Fourier transform (FT) from Cu K-edge EXAFS spectra (Fig. 3e) show that the major ...
Subsequently, the Se atoms on the outer surface of the PS-NH2@FeSe2 catalyst readily ligate with metal atoms to capture protons during the activation of K2S2O8. The formation of Se vacancies directly exposes the active sites of the metal and accelerates the electron migration, effectively ...
The elimination of organic compounds in the MFC is carried out by their microbial decomposition, the products of which are carbon dioxide, hydrogen protons, and electrons, the acceptor of which is the electrode. The decomposition of organic compounds can be illustrated by the example of acetic ...
During this stage, light energy is used to split water molecules into oxygen, protons, and electrons. The oxygen is released as a byproduct, while the electrons are transferred along the electron transport chain, generating adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate ...
Specifically, adsorption formation energies are approximately -2.5 eV for both octahedral and tetrahedral coordinated Fe²⁺, while for Fe³⁺ they are about -1.2 eV. Proton Transfer Mechanism: Upon adsorption onto the surface, a proton transfers to the NiOOH layer along with electrons, lead...
γ-iron, which is much softer in nature. it melts at 1536°c and boils at 2861°c. being a metal is magnetic in nature. why is iron different from other elements? the difference is the number of protons found in the nucleus of the atoms. the number of protons makes each element ...
Scaling of cross sections for multiple electron transfer to highly charged ions colliding with atoms and molecules For collision energies below 25 keV/amu cross sections for the transfer of up to 4 electrons in single collisions between multiply charged ions and neutral... A Müller,E Salzborn -...
The energy deposition in the absorber and deep-dose distribution produced by the transmitted primary particles and secondary electrons, secondary neutrons, secondary protons and secondary gamma have been analyzed. All produced secondary heavy particles and energies from four kinds of shielding materials ...
