The influence of microstructure and hardness on hydrogen embrittlement was determined and scanning electron microscopy (SEM) analysis was used to identify the respective operative failure micromechanisms. A significant loss in notched strength was observed when hydrogen was introduced during the tensile ...
Herein, a series of naphthalenediimide (NDI y ), possessing unique electron-deficient aromatic imides, were introduced to prepare D-A structured g-C3N4 (CN) derivative hybrid photocatalysts for photocatalytic hydrogen evolution (PHE) from water splitting. Remarkably, the modification with NDI y all ...
energy region. The absorption profile of the Pt-doped cluster is consistent with that of neutral [PtAu24]0where the Pt dopant is located at the centre of the core33. Evidently, replacing the central Au atom with Pt results in stable [PtAu24]0having a superatomic 6-electron configuration25,...
Battery electric vehicles are making headlines, but fuel cells are gaining momentum—with good reason. Hydrogen could play a vital role in the renewable-energy system and in future mobility.
The electron energy when the Hydrogen’s electron is in the quantum state n = 2, l = 1 is much smaller than μc2. Consequently, the probability functions calculated using Eqs. (2) and (5) superpose to each other almost perfectly (not shown). However, as shown in Fig. 2, ...
The energy of the emitted photon is the same as the change in energy of the electron in the transition of the electron between the given energy levels of an atom. Answer and Explanation: Identify the given infor...
Superoxide, the one-electron reduction product of oxygen is actually kinetically favored as the activation energy for simultaneous two electron reduction is considerably higher. Superoxide production occurs in mitochondria as the result of a leak from the electron transport chain that is pulled forward ...
For one-electron system, it takes two values: -\frac{1}{2} and \frac{1}{2} Fine structure and hyperfine structure As a charged particle, the moving electron generates a magnetic field. Thus, electrons with same principle number n have different energy levels because of the difference of...
Subsurface microorganisms, including methanogens, sulphate reducers, homoacetogenic bacteria and iron(iii) reducers can make use of H2as an electron donor, which may lead to an unwanted accumulation of biomass in the vicinity of the injection borehole and/or loss of H2(Ganzer et al.2013; Hagem...
transmission electron microscopy, and temperature programmed reduction. Specific surface areas of samples were also measured. The results obtained indicate that molybdenum increases thermal stability of the magnetite active phase and prevents metallic iron formation during the reaction. The oxidation–precipitat...
