作者: A Lodder 摘要: The amount of screening of a proton in a metal, migrating under the influence of an applied electric field, is calculated using different theoretical formulations. First the lowest order screening expression derived by Sham [ Phys. Rev. B 12 , 3142 (1975)] is evaluat...
Using semi-local density-functional theory as well as hybrid functionals and embedded correlated wavefunction methods as higher-level benchmarks, we show that the effective charge of a solvated proton in the electrochemical double layer or outer Helmholtz plane at all levels of theory is fractional,...
A protonpositive chargeand electron a negative charge but a neutron has neither. 质子带正电,电子带负电,而中子既不带正电,也不带负电. 互联网 Where atom is losing some of its electrons is said to be apositive chargeexisting. 在原子失掉一些电子的情况下,可以说是带了正电荷. ...
