Platinum Nanopowders for biomedical  Hydrogen and nano-platinum have a synergistic effect that can be used in conjunction with the treatment of oxidant stress disorders; Studies have shown that platinum nano particle-mediated photo-thermal effect in the treatment of bone metastases in nude mice can be a good inhibition of bone tumor growth and osteolytic bone destruction; Lactic acid bio-sensor based on nano - platinum black modification for rapid detection, etc.  2. Platinum Nanopowders as catalyst  Nano platinum are widely applied in catalyst part, Nano-platinum powder has excellent bio-catalytic activity, it can be applied to polymer hydrogenation, reduction and synthesis. Nano platinum also can be used as fuel cell catalyst, due to its high cost, due to its high cost, now some use nano nickle to replace the platinum, and some are looking for ways to improve nano platinum efficiency as catalyst in fuel cells to save cost. Last year Chinese researches have developed a superfine platinum nanowire catalyst on the surface of the zigzag, greatly increasing the surface activity and specific surface area of the fuel cell catalyst, increasing its overall catalytic activity by more than 50 times. 3. Platinum Nanopowders for cosmetics Platinum nanoparticles , due to its strong oxidation resistance Platinum can effectively remove free radicals in the human body. Play the anti-aging effect and at the same time to achieve whitening bright. Platinum Nanopowders can also be used for food preservative, car exhaust purification, etc. Nano platinum do have a lot of amazing functions, we cannot list its amazing functions one by one though.  If you're interstsed in Platinum Nanopowders, please feel free to contact us as hwnano@xuzhounano.com. more

    Sale Star Nano Material high quality Carbon Nanohorns
          Carbon nanohorn is a new allotrope of carbon found in recent years. It can be seen as a single layer of graphite, one end is an angular closed structure and the other end is an open structure. The diameter of the carbon nanowires is generally from 2 to 5 nanometers and the length is from several nanometers to tens of nanometers. The carbon nanowires usually aggregate into spherical aggregates of 50-100 nanometers in diameter, with one end of the pyramid pointing to the outside of the aggregate. The pyramidal hollow structure and the unique morphology of carbon nanohorn have great potential in catalyst carrier, fuel cell, lithium ion battery and drug transport carrier. Therefore, the synthesis and characterization of carbon nanohorn have become a hotspot in scientific research recent years. Carbon nanohorns CNHs have various important applications as below: (1) Adsorption and storage materials CNHs have a large specific surface area and high binding energy, can be used as a new type of adsorption materials, such as adsorption gas xenon and hydrogen, CNHs have two kinds of adsorption sites: the gap between the angle and the angle of the gap. The use of nitric acid to treat CNHs can increase the pore volume of the interior and the gap significantly and can be used to store supercritical methane. In addition, CNHs can also be used to adsorb liquids such as water, benzene and ethanol. (2) Catalyst carrier Unique structure of CNHs can enhance the durability of the catalyst. The Pd-CNHs can obtain the Pd-CNHs with an average size of 2.3 nm, and the gas phase reaction of H2-O2 and some liquid reaction, such as coupling reaction, which have good catalytic ability. The particle size of Pt particles synthesized by CNHs is only about 2 nm, and it has good dispersibility. Pt-CNHs as the electrode of fuel cell have very good activity and stability. (3) Drug carrier CNHs have a large specific surface area and numerous angular voids that can adsorb large amounts of molecules. Compared with CNTs, SWCNHs have smaller pore size and are suitable for adsorption of relatively small molecules. CNHs do not use metal catalysts to avoid cytotoxicity caused by metal impurities. CNHs are assembled into micron-like bundles or form spherical aggregates that enhance the permeability and retention of drugs under passive tumor targeting conditions, and tend to be enriched near tumor tissue to provide a higher resistance to tumor. (4) Electrochemical applications CNHs can be used as electrode materials in electrochemical sensors. CNHs modified glassy carbon electrode on the uric acid, dopamine and ascorbic acid and other good electrocatalytic performance; CNHs directly grown on the carbon fiber can be made of independent electrodes for lithium-ion batteries; through the opening of large size nano-window, CNHs can be built a high-capacitance supercapacitor in an organic solvent. (5) Other applications Tubular carbon material can absorb the light in the near infrared region so the cells can be killed by local photothermal therapy; CNHs and metal oxide composite materials can also be used for lithium ion battery anode material to improve the performance of the battery; and CNHs doped MgB2 will have magnetic properties, making it a new superconducting material. by Jemma  
  •  graphite powder
    high pure flake graphite powder, Graphite powder price
          High pure graphite powder is an important industrial raw material in industry, which is applied to lubrication, sealing, conductive, high temperature, refractory materials, chemical production and other industrial fields. What applies most of Graphite powder in industry should be high temperature resistance field. HW NANO MATERIAL SUPPLY FLAKE GRAPHITE POWDER, PARTICLE SIZE 100-200NM,300-500NM,1-2UM.99.95%         Graphite powder has a high melting point that can withstand more than 3000℃ temperature, so the graphite powder has good high temperature properties. Graphite powder for high temperature performance can be used for continuous casting graphite powder, graphite powder mold detergent, graphite crucible, graphite powder refractory bricks, lubricants, grease production. In the foundry industry, casting in the casting process is carried out in high temperature environment. In order to make the casting at high temperatures without deformation and not broken, it is necessary to join the casting graphite powder. Casting graphite powder can withstand forging high temperature and cast surface smooth, non-sticky sand to ensure casting quality.         Graphite powder crucible, graphite powder refractory bricks are added graphite powder so that they have a high temperature properties. The shortcoming of commonly used lubricants and grease is that they fail to withstand high temperatures. And they can not achieve lubrication property in high temperature. In the process of producing lubricating oil and grease, if dding graphite powder, it can not only increase the lubricating oil and grease lubrication performance, but also improve the degree of high temperature resistant.         Generally, rubber is insulated. If want for conductive need, adding some conductive materials is required. Graphite powder has excellent electrical conductivity and lubrication release. To process graphite into graphite powder, it will be with excellent lubrication and conductive properties. The higher purity of graphite powder, the better conductivity will achieve. We Hongwu International Group Ltd, with HWNANO brand, is a high-tech enterprise focusing on manufacturing, research, development and processing of nanoparticles and nanopowders. We have our own nano powders production base and R&D center located in Xuzhou, Jiangsu that can supply graphite powder available for nano size and micron size with small quantity for researchers and bulk order for industry groups. So if you have any questions or demands about graphite powder or other nano materials, please feel free to contact us. Thank you! by Jemma
