Abstract: A hydrogen leakage detecting material, and a preparation method therefor and the use thereof are provided. The hydrogen leakage detecting material has a color-changing substrate and an active component. The color-changing substrate is hexagonal-phase tungsten trioxide having a microstructure of a nanorod bundle formed by multiple nanorods, and the active component is noble metal nanoparticles. A starting reduction temperature of the hydrogen leakage detecting material on hydrogen is less than or equal to 100° C. The hydrogen leakage detecting material has a relatively high sensitivity to hydrogen under different conditions, and has significant color change and a shorter color change response time.

Abstract: A novel method of making a 3D-shaped 3D graphene (3D2G) is disclosed. The method involves a) 3D printing a catalyst slurry via Direct Ink Writing (DIW); b) depositing the printed slurry using chemical vapor deposition (CVD) to produce a nickel-graphene composite; and c) etching the nickel-graphene composite. The resulting composite is a porous, binder-free structure of pure 3D2G. In one embodiment, the catalyst slurry comprises nickel particles mixed with an organic solvent, a polymer, and a plasticizer. In another embodiment, the organic solvent is dichloromethane, the polymer is poly lactic-co-glycolic acid and the plasticizer is dibutyl phthalate.

Abstract: The present invention relates to a method for preparing a nano-titanate, a nano-titanic acid and a nano-TiO2 containing doping E or embedding E nanoparticles, and the use thereof. By using an E-doped Ti-T intermetallic compound as a titanium source, and reacting it with alkaline solution at atmospheric pressure and near its boiling-point temperature, an E-doped titanate nanofilm is prepared with high efficiency and in a short time. Through acid treatment and (or) heat treatment, a titanate nanofilm containing embedding E nanoparticles, an E-doped titanic acid nanofilm, and a titanic acid nanofilm and a TiO2 flake powder containing embedding E nanoparticles can be further prepared. Through a subsequent reaction at high temperature and pressure, the preparation of an E-doped titanate nanotubes and titanic acid nanotubes, and titanic acid nanotubes and TiO2 nanotubes/nanorods containing embedding E nanoparticles can be achieved in high efficiency and low-cost.

Abstract: Described herein is a nanostructured silicon carbonaceous composite material and methods for producing the same. The methods include formation of a metal organic framework/silica (MOF/SiO2) intermediate material and conversion of the MOF/SiO2 intermediate material to the nanostructured silicon carbonaceous composite material. Relatively inexpensive and/or recycled materials can be used as precursors in manufacturing the nanostructured silicon carbon composition material, which can be used in various applications, including as silicon anode material in a lithium-ion battery.

Abstract: A quantum dot including a core comprising a first semiconductor nanocrystal including a zinc chalcogenide and a semiconductor nanocrystal shell disposed on the surface of the core and comprising zinc, selenium, and sulfur. The quantum dot does not comprise cadmium, emits blue light, and may exhibit a digital diffraction pattern obtained by a Fast Fourier Transform of a transmission electron microscopic image including a (100) facet of a zinc blende structure. In an X-ray diffraction spectrum of the quantum dot, a ratio of a defect peak area with respect to a peak area of a zinc blende crystal structure is less than about 0.8:1. A method of producing the quantum dot, and an electroluminescent device including the quantum dot are also disclosed.
