  • High-quality single-layer tungsten disulfide powder achieves low-cost large-area production

    High-quality single-layer tungsten disulfide powder achieves low-cost large-area production

    January 7,2019.

    Recently, Ren Wencai, a researcher at the Advanced Carbon Materials Research Department of the National Institute of Materials Science, Institute of Materials Science, Chinese Academy of Sciences, has made new progress in the preparation of large-area high-quality uniform single-layer WS2 and flexible electronics applications. Based on binary phase diagram analysis and theoretical calculations, they found that gold is the only metal that does not react with sulfur at high temperatures to form sulfides, and gold has catalytic activity, which can effectively reduce the barrier of tungsten trisulfide vulcanization process, and gold at high temperature. The solubility of the tungsten atom is extremely low. On this basis, they proposed a surface-catalyzed atmospheric pressure CVD method using gold as a growth substrate to realize the preparation of high-quality, uniform single-layer millimeter-sized WS2 single crystals and large-area films. It is found that, similar to the growth of graphene on copper, the catalytic activity of gold and the extremely low solubility of tungsten in gold make the growth of WS2 on gold follow the self-limiting surface catalytic growth mechanism, thus ensuring a uniform single layer of high quality WS2 crystal. Growth. In addition, the single-layer WS2 prepared under normal pressure is weakly bonded to the gold matrix, so the electrochemical bubbling method can be used to achieve high-quality transfer of WS2 without damaging the gold matrix. The single layer WS2 produced by this method has a high crystalline quality and exhibits optical and electrical properties comparable to those prepared by mechanical stripping (far better than materials grown by inert matrix CVD). In addition, they use the characteristics of gold foil with good flexibility and chemical stability, and propose a non-destructive transfer method combining roll-to-roll and electrochemical bubbling to realize large-area single-layer WS2 film without destroying the gold matrix. Low cost continuous transfer to flexible transparent substrates such as PET, PEN, etc. Through the layer transfer, a large-area flexible transparent double-layer, multi-layer WS2 film and a WS2/graphene laminated heterostructure functional film can also be prepared. Using the roll-to-roll electrochemical bubbling lossless transfer method, they also realized the fabrication of a large-area flexible transparent single-layer WS2 thin film transistor array. The electrical properties of the flexible device are comparable to those of the SiO2/Si substrate and are bent. After 100 times, the electrical performance does not decay. The low-cost, large-area preparation of high-quality uniform single-layer WS2 single crystals and thin films lays the material foundation for their applications in flexible electronic/optoelectronic devices and valley electron and spintronic devices. The results were funded by the National Natural Science Foundation of China's Outstanding Youth Fund, major projects, i...

    Chinese scholars have developed a new nanowire catalyst with a diameter of only 1 nanometer.

    December 17,2018.

    The University of Science and Technology of China was informed that the research team of Hefei Microscale Materials Science National Research Center, Professor Zeng Jie and Professor Huang Hongwen of Hunan University have developed a new type of nanowire catalyst with a diameter of only 1 nanometer. According to reports, the proton exchange membrane fuel cell cathode catalyst has excellent catalytic activity and stability, and is expected to significantly reduce the optimal battery price of electric vehicles in the future. The results were recently published in the Journal of the American Chemical Society. The proton exchange membrane fuel cell has the advantages of zero emission, high energy efficiency and adjustable power. It is the most ideal driving power source for electric vehicles in the future and has broad market prospects. However, the kinetics of the oxygen reduction reaction at the cathode end of the proton exchange membrane fuel cell is very slow, and a large amount of noble metal platinum nanocatalyst is required as an electrode catalyst to maintain efficient operation of the battery, which makes the cost of the proton exchange membrane fuel cell very high, which Limiting its large-scale commercial applications. At present, many reported platinum-based catalysts have excellent mass activity, but most of them are not stable enough because the structure on which high-quality activity depends is thermodynamically unstable and develops high-quality and platinum-based catalysts with excellent stability. Extremely challenging Faced with this problem, the researchers developed ultrafine platinum-nickel-niobium ternary metal nanowire catalysts by fine-tuning the size, size and composition of platinum-based catalysts. Since the nanowires are only 1 nanometer in diameter, the surface platinum atoms account for more than 50% of the total platinum atomic ratio, exhibiting an extremely high atomic utilization rate and providing a structural basis for high catalyst activity. Tests have shown that the mass activity of the nanowire catalyst is 15.2 times that of the current commercial platinum carbon nanocatalyst. At the same time, after the catalyst was recycled 10,000 times in an oxygen atmosphere, only 12.8% of the mass activity was lost. Zeng Jie said that compared with the current commercial platinum carbon nanocatalyst, the carbon-supported ultrafine platinum-nickel-niobium ternary metal nanowire catalyst has significant improvement in mass activity and catalytic stability, and has good application potential. SAT nano Technology Material Co., Ltd. supply series of nanowires with different specification, such as copper nanowire, silver nanowire, copper oxide nanowires, copper hydroxide nanorods, please feel free to ask us the details.

    Nano-pigment on plastic spray becomes

    November 15,2018.

    Rose gold, champagne gold, green gilt, snow silver... These beautiful and shiny "metals" are actually plastic products! The ultra-dispersive color aluminum pigment products developed by the most advanced "nano-micro coating technology" were unveiled at the high-tech fair yesterday. The core technology that makes plastics look beautiful in metallic texture is “nano-micro coating technology”. In layman's terms, it is to put a layer of "clothes" on these pigments so that they can swim in the water like swimming in the water, and the colors are very scattered. The beautiful colors can be achieved. Metal plating is even the same as high-gloss paint, and the variety of aluminum pigments is very rich, including rose gold, champagne gold, bright silver, bright gold, green gold, red gold, blue gold, black gold, bronze, ancient silver and so on. In addition, another highlight of the “paint-free color aluminum pigment” is the world's first “paint-free” technology. Traditional oil-based coatings require multiple processes and are applied to the surface of the product. The “spray-free” technology allows the ultra-dispersive color aluminum pigment to be blended with plastic particles in a certain ratio before entering the blow molding, extrusion or injection molding process, which saves the process, saves energy, and because the pigment is "Fluid" in the material, even if it is bumped, "can not paint." According to reports, the current "free-spraying color aluminum pigment" has been out of the laboratory, industrialized, used in automotive manufacturing, small appliance manufacturing and high-end packaging. "In the future, the main application range of spray-free metal pigment technology is non-metallic parts for automotive interior and exterior body. It can also be applied to computers, mobile phones and home appliances, collectively referred to as 3C appearance parts." The person in charge said, for example, in the field of automobile manufacturing. In the future, the car will have more colors and can even be customized. With the spray-free technology, not only can the complex spraying process be reduced in the process, but the pigment is “melted” in the body. Once the vehicle is paralyzed, there is no need to worry about the problem of the touch up. At the same time, the future car body may also use a large number of spray-free pendants to achieve lightweight, which can reduce the energy consumption of the entire car.

  • Nanotechnology is also a

    Nanotechnology is also a "double-edged sword"

    November 4,2018.

    In our daily lives, nanotechnology will bring unexpected surprises to people. With nanometer (nm) coating, the refrigerator can be made into antibacterial, can be made into sterile tableware, can be made into self-cleaning glass and tiles without scrubbing. Using nanotechnology to make a micro drug delivery device, it can accurately reach the lesion site and reduce the adverse reactions of the drug. Nanomaterials are made up of ultra-fine particles of less than 100 nanometers (nm) and are unique in size and function beyond imagination. Nanotechnology is also a "double-edged sword". While bringing convenience to life, it also has potential risks. Environmental ecological risk of nanomaterials Researchers have used nematode model organisms to find that nanomaterials that enter the environment can be transported along the food chain, accumulating in high-level organisms and exhibiting toxic effects. It not only causes damage to the parents, but also damages future generations. In addition, physical, chemical and biological transformations occur when nanomaterials enter the environment, which changes the physicochemical properties and ultimately affects the toxicity of nanomaterials. Studies have found that ionic strength in the environment can dedicate nanosilver to release smaller nanoparticles. This small particle size nanosilver is more toxic than the original nanosilver. The pH in the water environment and the natural organic fulvic acid have similar effects. "Aging" is another major change in the release of nanomaterials into the environment. Nano-zinc oxide undergoes morphological changes and changes in composition during the aging process of the water environment, and flakes appear around the particles. The research team used the latest technology to analyze the physicochemical transformation of nano zinc oxide in the water environment, and found that the newly formed material mainly contains basic zinc carbonate and zinc hydroxide. At the same time, the study also found that the water environment aging process affects the toxicity of nano zinc oxide to chlorella. Researchers say that aging zinc oxide has low toxicity to chlorella, which is due to the physical and chemical transformation of nano-zinc oxide during the aging process of water environment, gradually producing low-toxic basic zinc carbonate and zinc hydroxide, which reduces the small The toxicity of chlorella. Using mammalian cell model studies, it has also been found that the cytotoxicity of nano zinc oxide decreases with aging, but it is surprising that its neurite outgrowth is significantly enhanced. Studies have shown that the transformation of physicochemical properties of nano-zinc oxide with the aging time plays an important role in the induction of mammalian cytotoxic effects. Nanomaterials combined with contaminants can produce complex toxicity Due to the high specific surface area and unique surface chemistry of nanomaterials, when it enters the environment, it can be co...
