چکیده
The defect-free structure of Mo-based materials is a “double-edged sword”, which endows the material with excellent stability, but limits its chemical versatility and application in electrochemical hydrogen evolution reaction (HER). Carbon doping engineering an attractive strategy to effectively improve performance catalyst maintain their stability. Herein, we report cross-linked porous carbon-doped MoO2 (C–MoO2)-based Ru/C–MoO2 for HER, prepared by convenient redox solid-phase (SPR) RuO2/Mo2C composite precursor. Theoretical studies reveal that due presence carbon atoms, electronic C–MoO2 has been properly adjusted, loaded small Ru nanoparticles provide fast water dissociation rate moderate H adsorption strength. In under pH-universal environment, electrocatalyst exhibits low overpotential at current density 10 mA cm−2 Tafel slope. Meanwhile, Ru/C-MoO2 stability more than 100 h initial cm−2.

All - Termination ( SCP )
We recently introduced the All-Termination(T ) problem: given a termination solver T and a function F , find every subset of the formal parameters to F whose consideration is sufficient to show, using T , that F terminates. These subsets can be harnessed by a theorem prover to locate and justify induction schemes, and are also useful for guiding rewriting heuristics and ensuring their terminati...
متن کاملImpact of SCP-2/SCP-x gene ablation and dietary cholesterol on hepatic lipid accumulation.
While a high-cholesterol diet induces hepatic steatosis, the role of intracellular sterol carrier protein-2/sterol carrier protein-x (SCP-2/SCP-x) proteins is unknown. We hypothesized that ablating SCP-2/SCP-x [double knockout (DKO)] would impact hepatic lipids (cholesterol and cholesteryl ester), especially in high-cholesterol-fed mice. DKO did not alter food consumption, and body weight (BW) ...
متن کاملThree-dimensional structure/function analysis of SCP-2-like2 reveals differences among SCP-2 family members.
Mosquito sterol carrier protein-2 (AeSCP-2) and sterol carrier protein-2-like2 (AeSCP-2L2) are members of the SCP-2 protein family with similar expression profiles in the mosquito life cycle. In an effort to understand how lipids can be transported by different SCP-2 proteins, the three-dimensional crystal structure of AeSCP-2L2 was solved at 1.7 A resolution. AeSCP-2L2 forms a dimer and binds ...
متن کاملSCP-2/SCP-x gene ablation alters lipid raft domains in primary cultured mouse hepatocytes.
Although reverse cholesterol transport from peripheral cell types is mediated through plasma membrane microdomains termed lipid rafts, almost nothing is known regarding the existence, protein/lipid composition, or structure of these putative domains in liver hepatocytes, cells responsible for the net removal of cholesterol from the body. Lipid rafts purified from hepatocyte plasma membranes by ...
