Abstract Alkaline hydrogen evolution reaction (HER) for scalable production largely hinges on addressing the sluggish bubble‐involved kinetics traditional Ni‐based electrode, especially ampere‐level current densities and beyond. Herein, 3D‐printed sulfide (3DPNS) electrodes with varying scaffolds are designed fabricated. In situ observations at microscopic levels demonstrate that bubble escape velocity increases number of hole sides (HS) in scaffolds. Subsequently, we conduct multiphysics...
Supercritical-pressure heat transfer of a hydrocarbon fuel has practical importance in precooling technology hypersonic air-breathing propulsion systems. Heat n-decane helical tubes is numerically studied at supercritical pressure 5 MPa, with consideration endothermic pyrolysis and surface carbon deposition. The effects curvature on temperature variations, pyrolytic chemical reactions, coking are analyzed. Results indicate that, owing to the centrifugal force secondary flows, averaged wall...
Abstract Solar interfacial evaporation is a promising method for solving the global shortage of fresh water. While 2D evaporators can efficiently localize solar‐converted heat at thin layer water–air interface, 3D solar maximize energy reutilization while maintaining effective mass transport ability, few studies are conducted to explore effect gradient porosity on performance. In this study, multifield assisted strategy based structure with high tortuosity proposed, which creates thermal...
Abstract Conducting polymer hydrogel can address the challenges of stricken biocompatibility and durability. Nevertheless, conventional conducting hydrogels are often brittle weak due to intrinsic quality material, which exhibits viscoelasticity. This property may cause a delay in sensor response time hysteresis. To overcome these limitations, we have designed wrinkle morphology three‐dimensional (3D) substrate using digital light processing technology then followed by situ polymerization...
