Magnesium Oxide nano particles antibacterial 30-50nm         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(30-50nm, 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. Our products have been sold to many countries around the world.

Carbon Nanotubes have excellent electrical, mechanical and thermal properties and they inevitably determine the broad application prospects in the fields of physics, chemistry, information technology, environmental science, materials science, energy technology and other sciences. Hongwu Nano has manufactured carbon nanotubes with various specifications for years.

With β-Sic do electronic packaging materials, heaters, heat exchangers have high thermal shock resistance, good thermal conductivity,

Silicon nanopowders sepcification: 30-50nm 99%+, brown yellow, good spherical 100-200nm 99.9%+,brown black, irregular crystal form 300-500nm 99.9%+,brown black, irregular crystal form 1-2um 99.9+%, dark brown, irregular crystal form Silicon nanopowder properties: High purity, good dispersion performance, small size, uniform distribution, large surface area, high surface activity, low apparent density. Nano Silicon powders is non-toxic, odorless, and with active features. Nano silicon powder is a new material for high capacity lithium battery anodes. Silicon nanopowders use for the rechargeable lithium battery cathode material: Due to the high absorption rate of nanometer silicon and lithium batteries, the nano silicon for lithium can significantly increase the capacity of lithium battery (theory can reach 4000mA / h). Nano silicon powder and graphite replace the nano carbon powder as raw materials for the lithium anode material, use the mechanical milling method for preparing the best ratio of silicon / graphite composites, silicon and graphite, which is 1:9. Composition Si-C composite material, can effectively reduce the expansion when silicon absorption lithium ions, increase the affinity with the electrolytic solution, and easily dispersed and can improve the cycle performance. Nano silicon nanowires made of silicon powder used in rechargeable lithium battery anode material in or on the surface of the nano silicon powder coated graphite anode materials used in rechargeable lithium battery, rechargeable lithium batteries can be improved more than three times the capacity and charge-discharge cycles.

Treatments can enhance more performance of carbon nanotubes and make it more widely used in various fields. Some common modified types include copper, nickel coating, carboxylated, hydroxylated, amination, etc..Hongwu Nano can customized CNTs with different modification accordingly to the requirements.
