A pine‐shaped Pt nanostructured electrode with under‐water superaerophobicity for ultrahigh and steady hydrogen evolution reaction (HER) performance is successfully fabricated by a facile easily scalable electrodeposition technique. Due to the lower bubble adhesive force (11.5 ± 1.2 μN), higher contact angle (161.3° 3.4°) in aqueous solution, smaller size of bubbles release electrode, incomparable final repellence from submerged surface ease, achieved, compared that nanosphere flat...
Layered double hydroxides (LDHs) are a family of high‐profile layer materials with tunable metal species and interlayer spacing, herein the LDHs first investigated as bifunctional electrocatalysts. It is found that trinary LDH containing nickel, cobalt, iron (NiCoFe‐LDH) shows reasonable performance, while exploiting preoxidation treatment can significantly enhance both oxygen reduction reaction evolution activity. This phenomenon attributed to partial conversion Co 2+ 3+ state in step,...
Due to the unique structural advantages, hierarchical Co<sub>3</sub>O<sub>4</sub>@NiO nanoarrays can be regarded as advanced electrodes for Ni–Zn batteries.
Sandwich-type N-doped graphene based carbon materials with a wrinkled sheet-like morphology were prepared, and they demonstrated remarkable performances as supercapacitor electrodes.
Rechargeable lithium–sulfur (Li–S) batteries, which originate from the merits of extraordinary theoretical specific energy density, abundant resources, and eco-friendly character, have received ever-growing attention. However, their practical applications are seriously hampered because poor conductive property sulfur discharging products, severe dissolution migration lithium polysulfide intermediates, huge volumetric variation particles upon cycling. Here, double-shelled Co3O4 carbon...
As a high-efficiency energy storage and conversion device, lithium-ion batteries have high density, received widespread attention due to their good cycle performance reliability. However, currently commercial lithium usually use organic solutions containing various salts as liquid electrolytes. In practical applications, electrolytes many shortcomings shortcomings, such poor chemical stability, flammability, explosion. Therefore, the electrolyte has great safety hazard. The of solid ensures...
The catalytic combustion of methane has gained much attention as a sustainable technology, due to concerns about the environmental impact unburnt emissions from natural gas vehicles. Researchers have explored alternatives precious metal catalysts for combustion, with focus on perovskite oxides known their excellent activity and sintering-resistance capacity. In this study, LaFeO3 material was synthesized subsequently subjected nitric acid etching treatment modify its surface. It found that...
Hierarchical nanoarchitecture and porous structure can both provide advantages for improving the electrochemical performance in energy storage electrodes. Here we report a novel strategy to synthesize new electrode materials, hierarchical Co-based layered double hydroxide (PLDH) arrays derived via alkali etching from Co(OH)2@CoAl LDH nanoarrays. This not only has benefits of nanoarrays including short ion diffusion path good charge transport, but also possesses large contact surface area...
Ni-rich LiNi0.6Co0.2Mn0.2O2 nanomaterials with a high percentage of exposed {010} facets have been prepared by surfactant-assisted hydrothermal synthesis followed solid-state reaction.

Current materials comprising suture anchors used to reconstruct ligament-bone junctions still have limitation in biocompatibility, degradability or mechanical properties. Magnesium alloys are potential bone implant materials, and Mg2+ has been shown promote healing. Here, we Mg-2 wt.% Zn-0.5 Y-1 Nd-0.5 Zr (ZE21C) alloy Ti6Al4V (TC4) prepare the patellar ligament-tibia SD rats. We studied degradation behavior of ZE21C anchor via vitro vivo experiments assessed its reparative effect on...
Metal sulfides are promising lithium-ion battery anode materials with high specific capacities, but there has been little in-depth discussion on the reaction mechanism of metal sulfides. In this study, a robust bimetallic sulfide heterogeneous material (Sb2S3-Co9S8/NC) based metal-organic framework was designed. The combination in situ X-ray diffraction and ex transmission electron microscopy revealed phase evolution behavior during first cycle. During lithiation process, Sb2S3 undergoes...
