Epitaxial chemical vapor deposition (CVD) growth of uniform single-layer graphene is demonstrated over Co film crystallized on c-plane sapphire. The single crystalline realized the sapphire substrate by optimized high-temperature sputtering and successive H2 annealing. This enables formation graphene, while a polycrystalline deposited SiO2/Si gives number flakes with various thicknesses. Moreover, an epitaxial relationship between as-grown lattice observed when synthesis occurs at 1000 °C;...
Abstract The maximizing daily freshwater yield on the ocean surface necessitates all‐day water harvesting technologies and materials. This is realizable by taking advantage of natural sunlight humid air, which can drive daytime solar desalination nighttime fog collection, respectively. To this end, two types hierarchically porous microneedle array structures, demonstrate superior capabilities for efficient capturing photothermal evaporation, respectively, are prepared. gel‐forged arrays with...
Size, orientation, and boundary of graphene domains are the current focus chemical vapor deposition (CVD) growth because they closely related to graphene's physical properties. Here, we study domain structure single-layer grown by ambient pressure CVD over heteroepitaxial Cu(111) Cu(100) films. Low energy electron microscope measurements reveal that film gives uniform whose orientation is consistent with underlying Cu lattice for areas 1 mm2. On other hand, on exhibits clear multidomain two...
Abstract As a promising electrode material, Ni‐based nanomaterials exhibit remarkable electrochemical catalytic activity for nonenzymatic glucose sensors. In this paper, Nickel–Iron layered double hydroxide (NiFe‐LDH) film with ultrathin nanosheets and porous nanostructures was synthesized directly on Ni foam (NF) by one‐step hydrothermal method. The as‐obtained NiFe‐LDH adopted detection without further treatment. an integrated binder‐free sensor, the NiFe‐LDH/NF hybrid exhibits superior...
The Lancet Commission on Global Surgery established the Three Delays framework, categorising delays in accessing timely surgical care into seeking (First Delay), reaching (Second and receiving (Third Delay). Globally, knowledge gaps regarding for fracture care, lack of large prospective studies informed rationale our international observational study. We investigated hospital admission as a surrogate explored factors associated with delayed admission.
The development of nonprecious electrocatalysts with high hydrogen evolution reaction (HER) activity for water splitting is highly desirable but remains a significant challenge. Molybdenum disulfide (MoS2) has been demonstrated as good candidate; however, insufficient active sites along poor conductivity significantly hinder the overall efficiency MoS2. In this work, we present method to activate commercial MoS2 by concentration nitrogen doping via facile high-temperature treatment routine....
Abstract The conflict between high sensitivity and wide sensing range greatly limits the extensive application of flexible pressure sensors. To produce a sensor with both is still challenging work. Herein, highly sensitive piezoresistive sensors are developed by combining alkali‐treated 3D crinkled MXene microstructured polydimethylsiloxane (PDMS). Sensors different‐roughness PDMS films as substrate unprocessed conductive material prepared to clarify geometric design for ultra‐wide (0–800...
Single-layer and high-quality graphene was synthesized over Cu foil by atmospheric pressure chemical vapor deposition (CVD) without additionally introducing H2 gas during the growth time. We compared surface morphology evolution as a function of time, with supply AFM, SEM, EBSD, Raman spectroscopy. The comparison results suggested that absence time caused orientated wrinkles, small grain size, more boundaries on surface, well high quality rapid rate. cross sectional TEM, HR-TEM, SAED...
The tailor-made transition metal alloy-based heterojunctions hold a promising prospect for the electrocatalytic oxygen evolution reaction (OER). Herein, series of iron–cobalt bimetallic alloy are purposely designed and constructed via newly developed controllable phase separation engineering strategy. results show that process component distribution rely on molar ratio (Fe/Co), indicative content dependent behavior. Theoretical calculations demonstrate electronic structure charge can be...
