Magnesium (Mg) alloys have shown great prospects as both structural and biomedical materials, while poor corrosion resistance limits their further application. In this work, to avoid the time-consuming laborious experiment trial, a high-throughput computational strategy based on first-principles calculations is designed for screening corrosion-resistant binary Mg alloy with intermetallics, from thermodynamic kinetic perspectives. The stable intermetallics low equilibrium potential difference...
Abstract The corrosion susceptibility of magnesium (Mg) alloys presents a significant challenge for their broad application. Although there have been extensive experimental and theoretical investigations, the mechanisms Mg are still unclear, especially anodic dissolution process. Here, thorough investigation based on ab initio molecular dynamics metadynamics simulations has conducted to clarify underlying mechanism anode propose effective strategies enhancing resistance. Through...
Phosphorus-containing scale inhibitors have been widely used to mitigate CaCO3 scaling on the surface of metal device. In this work, antiscale performances two typical additives, sodium salts hexametaphosphate (SHMP) and ethylenediaminetetramethylene phosphonate (EDTMPS), were evaluated carbon steel through comparing behavior under self-corrosion cathodic polarization conditions, respectively. Results reveal that anodically released Fe2+ ions exert important influences their at steel–water...
Abstract Traditional unidirectional cold expansion technology usually generates non-uniform distribution of residual stress in the thickness direction holes, which is harmful to improvement fatigue life holes. The present work proposed a bi-directional procedure realize homogenization expanded hole, thereby further improved antifatigue performance hole. For this aim, series finite element (FE) simulations were carried out investigate effectiveness and optimize process parameters. results...
A semi-empirical model based on the mixed potential theory and first principles calculation is developed in this study to analyze galvanic corrosion of Mg-Ge alloys composed Mg Mg2Ge. The thermodynamic driving force matrix dissolution much stronger than that Mg2Ge second phase, will serve as local cathode during corrosion. combination large anode equilibrium difference between Mg2Ge, Schottky barrier across interface indicates phase can prevent grain from serving impede electron transfer...
Suitable electrode catalyst is a critical factor for the application of direct methanol fuel cell. In this research, layered double hydroxides (LDH) are chosen as supporting material platinum to improve its electrochemical activity, tolerance carbonaceous intermediates well reduce cost electrode. Experimental results show that low amount (42 and 29 mg/g) can be intercalated into interlayer LDH with thickness less than 1 nm, which effectively enhance activity reduced cost. Both MgAl-LDH/Pt...
Catalyst of Fe–Co-layered double hydroxide (LDH) prepared by co-precipitation could effectively improve the degradation pharmaceutical intermediate – p-toluenesulfonic acid (p-TSA) in water during ozonation. The experimental results showed that under condition pH 7.9, catalyst dosage 0.1 g/L and aqueous ozone concentration 6.2 mg/L, 20 mg/L p-TSA obtained a TOC removal percentage 85%. To search for mechanism Fe–Co LDH catalytic ozonation organic pollutants, hydroxyl radicals were measured...
Existing tracking methods mainly focus on learning better target representation or developing more robust prediction models to improve performance. While performance has significantly improved, the loss issue occurs frequently due failures, complete occlusion, out-of-view situations. However, considerably less attention is paid self-recovery of methods, which crucial for practical applications. To this end, we propose a recoverable framework, RTracker, that uses tree-structured memory...
