  • Ni2O3 Nickelic Oxide Nanoparticles Application
    Ni2O3 Nickelic Oxide Nanoparticles Application
        We, Hongwu Nanometer, are offering different shape & size metal oxide Nanoparticles and Nanopowders including high quality Ni2O3 Nickelic oxide nanoparticles. Stock#: S672, particle size 20-30nm, 99.9%. 1. Nickelic Oxide Catalyst     Ni2O3 is a kind of oxidation catalyst with good catalytic effect.  2. Ceramic additives and colouring agent of glass     Nano Ni2O3 powder is used to improve the impact strength of ceramic products. When adding NiO (O.02 (wt)%), the electrical properties such as piezoelectric properties and dielectric properties can be improved greatly. The addition of NiO nanoparticle to the glass mainly controls the color of the glass, and a small amount of NiO is contained in the transparent brown transparent glass which can absorb ultraviolet rays. Transparent glass mirrors and decorative glass are added the moderate amount of NiO nanopowder as a coloring agent. 3. Battery electrode material     With the continuous development of communication and information technology, the capacitor has also achieved unprecedented development. Nowadays, supercapacitors have become a research hotspot because they have much higher energy densities and much higher power densities than traditional ones. Research showed that ruthenium oxide is currently the most studied and the best performance of the electrochemical capacitor electrode material. However, its very high price hindered its large-scale applications. And the large internal resistance of activated carbon makes people look to the transition metal oxides. With quasi-capacitive phenomena, transition metal oxides become the super capacitor electrode materials. At present, the use of Ni, Mn, Co and other oxides with the small internal resistance, low cost and large capacity and other characteristics for battery electrode material attracted concerns a lot.As cathode of carbonate molten salt fuel cell, nano NiO, with gas or natural gas as fuel, produced clean energy with higher power generation efficiency than the traditional thermal power generation. Moreover, compared with the ordinary NiO battery, the nano NiO battery owns obvious discharge advantages,  the is obviously increasing discharge capacity, and the greatly improved electrochemical performance of the electrode. 4. Sensor material     Ni2O3 nanopartilce has received more and more attention recent years as gas sensor materials. At present, nano NiO has been made into the formaldehyde sensor, CO sensor, H2 sensors used in the actual production. In short, with the rapid development of science and technology, more and more properties of Nickel Oxide nanoparticle woud be dig out and applied in wider fileds. If you are interested in developing  some application, please get in touch. thank you. by Corrine

  • Magnesium Oxide nano particles antibacterial 20-30nm
    Magnesium Oxide nano particles antibacterial 20-30nm
    Magnesium Oxide nano particles antibacterial 20-30nm         Magnesium Oxide nano particle(MGO) with a wide band-gap is an important inorganic material. MgO nano powder is a promising antibacterial agent because of its high resistance to harsh environment.  For the antibacterial ablity of MgO nano powder is related to the particle size. The antibacterial activity was increased with the decrease of the particle size of MgO nano. For particles in the size range 50-70 nm, the bactericidal efficacy of nano-MgO increased slowly with decreasing particle size. When the size under 40 nm, the bactericidal efficacy of MgO nano increases a lot and could kill more bacteria. This proves that the particle size is smaller the antibacterial efficacy of MgO is stronger. MgO nano particles penetrated the bacterial cell wall and cell membrane. For the size is smaller, and then killed more bacteria. Also MgO nano particles with large specific surface area increase as the size of the nano particles decreases. For the large surface area with lots of reactive groups on the particle surface and high antibacterial activity will be obvious.       Hongwu International Group Ltd is committed to provide high-quality Magnesium Oxide nano particles(20-30nm, 99.9%) with the most reasonable price for customers who are doing nanotech research and have formed a complete cycle of researching, manufacturing, marketing and after-sale servicing.
