catalysts is that the atomic number of central B atom should be between group VB and VIIIB, and the electron difference between central A atom and B atom should be large enough, and the selectivity of NRR or hydrogen evolution reaction (HER) could be calculated through the prediction formula...
Up to 4 Na+ ion per formula unit can be inserted during the first discharge. An intensive refinement of the synchrotron X-ray diffraction (SXRD) patterns of discharged NaxCa0.5Ti2(PO4)3 evidenced the existence of five regions depending on the sodium content while the crystal ...
However that may be, reflection on resonance hybrids, tautomerism, the “riddle of benzene,” and such like is still a relatively neglected theme in the philosophy of chemistry. With the decline of dialectical materialism as a political force, discussions on the philosophy of chemistry in Eastern...
preferably using the waste heat of the power plant. Depending upon the chemistry, chemical hydrogen approaches often are exothermic upon release of hydrogen to the power plant, or optimally thermal neutral. By virtue of the chemistry used, chemical hydrogen approaches require significant energy to reg...
The term free energy perturbation (FEP) often refers to a particular class of alchemical method7 but has in recent years been applied to alchemical binding free energy methods more generally; henceforth, we will refer to all alchemical binding free energy methods, including thermodynamic integration,...
For other applications (e.g., in chemistry or physics) in which compounds containing anions other than oxygen may predominate, a more sophisticated correction scheme may be warranted. For example, the “Coordination-Corrected Formation Enthalpy” (CCE) method of Friedrich et al.16 treats polyanions...

The pressure-dependent rate constants are also important in the development of accurate PAH chemistry. However, the existing reaction kinetic mechanisms still lack the accuracy of these types of reactions. For example, the rate constants for the most widely known hydrogen abstraction carbon addition (...
