Rough surfaces are characterized by fractal geometry using a modified two-variable Weierstrass–Mandelbrot function. The developed algorithm yields three-dimensional surface topographies representative of engineering rough surfaces. This model is incorporated into an elastic-plastic contact mechanics analysis two approaching Closed form solutions for the elastic and plastic components total normal force real area derived in terms parameters, material properties, mean separation distance....

Practical applications of lithium-sulfur batteries are simultaneously hindered by two serious problems occurring separately in both electrodes, namely, the shuttle effects lithium polysulfides and uncontrollable growth dendrites. Herein, to explore a facile integrated approach tackle as well guarantee efficient charge transfer, we used two-dimension hexagonal VS2 flakes building blocks assemble nanotowers on separators, forming symmetrical double-side-modified polypropylene separator without...

Abstract Simple inorganic salts are used to tune N‐containing conjugated microporous polymers (CMPs) synthesized by Buchwald–Hartwig (BH) cross‐coupling reactions. Poly(triphenylamine), PTPA, initially shows a broad distribution of micropores, mesopores, and macropores. However, the addition affects all porous network properties significantly: pore size is narrowed range only, mimicking COFs MOFs; BET surface area radically improved from 58 m 2 g −1 1152 ; variations anion cation sizes...

Abstract Transition metal sulfides as anode materials for sodium‐ion batteries (SIBs) have the advantage of high capacity. However, their cycle‐life and rate performance at ultra‐high current density is still a thorny issue that limit applicability these materials. In this paper, carbon‐embedded heterojunction with sulfur‐vacancies regulated by ultrafine bimetallic (vacancy‐CoS 2 /FeS @C) robust interfacial C‐S‐Co/Fe chemical bonds successfully synthesized explored an material battery. By...

Abstract Facilitating equilibrium in the nitrogen cycle, electrochemical nitrate reduction (NitRR) to ammonia stands as a carbon‐free method for synthesis. Copper‐based catalysts, renowned NitRR, face hurdle supplying sufficient hydrogen radicals (*H) efficient hydrogenation of NitRR intermediates. Addressing this, NiMoO 4 is leveraged an excellent *H donor, synergistically coupling it with copper‐based catalyst. The work introduces high‐performance /CuO nanowire (NW)/Copper foam (CF)...
