Brewer intermetallic bonding theory interrelates the average electronic configuration of hypo–hyper-d-electronic combinations of transition metals with their crystal structure (bcc−dn−1s, hcp−dn−2sp, fcc−dn−3sp2, where n=d+s+p, the total number of valence electrons) [47], [48...

where ptot is the total pressure and pi is the partial pressure of background species i. The ion mobility coefficients μj are calculated similarly. First, the ion mobility of ion j in background neutral i is calculated using the low-E-field Langevin mobility expression [219]. Then Blanc’...
Also, at 1 mA cm−2, the overpotential is frequently called the onset potential, which indicates the intrinsic activities of electrocatalysts in order to trigger electrochemical reactions and affects the total performance remarkably. The current density on which photovoltaic cells are generally active ...
boundaries.115Because space-charge effects are also likely contributors in blocking proton conduction across the grain boundaries of hydrated perovskites (as previously discussed), it may be possible to leverage an optical approach similar to that of Defferriere et al. to enhance total proton ...

This is because the wavelength of light absorbable by the semiconductor materials such as TiO2 and ZnO is short; that is, these semiconductor materials can only absorb light having a wavelength of approximately 400 nm or less, so that the proportion of utilizable light in the total sunlight is...

Theoretical calculation was performed with the Vienna Ab initio simulation package (VASP) based on the density functional theory (DFT) methods [26,27]. The projector-augmented wave (PAW) method was used to describe the interaction of the core electrons and nucleus with the valence electrons [28...
