Physical Review E, 2017 Experiments in several laboratories have demonstrated that identical materials brought into repeated contact generate unexplained and growing surface charge domains. Here we show that the growth of charge from these experiments can be fitted to a previously developed first-principles model for contact charging based on feedback of random surface ...

The influence of surface currents on pattern-dependent charging and notching [PDF]
, 1998 Surface charge dissipation on insulator surfaces can reduce local charging potentials thereby preventing ion trajectory deflection at the bottom of trenches that leads to lateral sidewall etching (notching). We perform detailed Monte Carlo simulations of

Effect of cathodic hydrogen charging on the surface of duplex stainless steel [PDF]
, 1993 The effect of cathodic hydrogen charging on the mechanical properties of steels has been extensively investigated (1-5). There is a general agreement, that cathodic harging during a tensile test leads to reduction in ductility, and embrittlement (5-7 ...

The Journal of Chemical Physics, 2022 Electric double layers are ubiquitous in science and engineering and are of current interest, owing to their applications in the stabilization of colloidal suspensions and as supercapacitors. While the structure and properties of electric double layers in electrolyte solutions near a charged surface are well characterized, there are subtleties in ...
