Silicon nano technology reforming graphite cathode lithium batteries       Cathode technology of the existing lithium batteries has reached the limit. In order to meet the needs of a new generation of energy, the development of new cathode technology of lithium batteries is imminent. Silicon cathode, with the ultra-high specific capacity and rich reserves, has become one of the most representative new technology.     Compared to the traditional graphite cathode, a major obstacle to the Silicon cathode technology on the road of industrialization is that low gel content cause unsatisfactory effect of electrode mixing.     On account of this, some researchers integrated graphite cathode technology and Silicon nano technology and have developed a new and can be mass-produced C- nano Si- graphite composite cathode materials. During the lithiation process, Si nanoshells can be expanded as the volume change. No matter nano-Si hollow shell in the graphite , or a nano-Si intermediate layer between the graphite and carbon, it can keep the shape intact and not be broken or left over between Si and graphite. This special structure, on the one hand to ensure compatibility between the Si and natural graphite, on the other hand avoid the severe side effects caused by traditional mechanical mixing graphite powder and residual Silicon particles.     Silicon Nano Powder is generally immediately available here with particle size 30-50nm,100-200nm,300-500nm,1um. Chinese Hongwu International Group LTD with HW NANO brand can produce most materials in high purity forms and ultrafine particle size.

Zero-valent nano iron magnetic powder for wastewater/sewage treatment     Hongwu International Group Ltd offer a highly diverse range of powder grades with average grain sizes from approx. 20nm to 150nm. We provide technical support in the selection of the powders suitable for specific applications and for questions regarding process optimization.     Zero-valent nano iron powder have certain magnetic, and under the action of magnetic field can be separated easily and quickly from the wastewater solution, can effectively remove chlorinated hydrocarbon, diphenyl ether, aromatic nitro and polycyclic aromatic hydrocarbons fluorene, etc.  The decontamination mechanism of nano iron: 1. The reduction of nano iron     the iron is active metal with reducing power, thus it can directly reduce dye into amino organic matterin in the partial acid aqueous.Because amino organic color looks light, and easy to be oxidized decomposition, so the chroma of wastewater can be reduced. Some heavy metal ions in the wastewater can be reduced by iron. 2. Micro electrolysis     Iron has electrochemical properties. Its electrode reaction product the new ecological [H] and fe2+ can make the oxidizing reduction with many components in wastewater, dyeing assistant agent can be damaged, broken, loss auxochromic ability; It can make the macromolecular material decompose into small molecule intermediates, and make some difficult biochemical degradation of chemical material become handle easily to improve the water biological properties. 3. The coagulation adsorption     Under the condition of partial acid wastewater it will produce large amounts of Fe2+ and Fe3+, when the PH value to alkaline and aerobic,ferric hydroxide hydrogen and ferrous hydroxide floc form, iron hydroxide hydrolysis could also generate ferrous hydroxide complex ion, which all have very strong flocculation performance, so original suspended solids in the waste water, and insoluble substances produced by micro electrolysis and chromaticity of insoluble substance can be adsorption condensation, hence the wastewater got the purification.     Thus, Zero-valent nano iron powder processing wastewater a comprehensive effect of reduction, micro electrolysis, coagulation adsorption.

Zinc Oxide nanowires/ZnO NWs, as an ideal material for the preparation of a Schottky contact type devices. Hongwu nanometer is professional manufacturer, supplier and exporter in china for nano materials in china. Our ZNO zinc oxide nanowires specification as follows: 1. D<100nm,L>5um,99.9%                2. D:100-200nm,L>1um,99.9%                          As nucleic acid detection is more and more widely applied to genotyping technology, clinical diagnostics and biomedical research and other fields, the traditional optical detection and real-time PCR technology have some disadvantages, such as high cost, no longer can meet the demand that the devices require the testing with high cost-effective, high speed and high sensitivity. By contrast, the one-dimensional material represented by the unmarked detection device, because of a high specific surface area, can offer the possibility for low-cost, simple and effective DNA testing. FET based on semiconductor nanowires is such a great potential device. Wherein, changing the metal - semiconductor interface of Schottky barrier height(SBH)can modulate device performance, which is a hotspot for researchers.        Zinc Oxide nanowires/ZnO NWs with excellent semiconductor and piezoelectric performance, is an ideal material for the preparation of a Schottky contact type devices. Researchers of the National Center for Nanoscience and other institutions made use of exerting external strains on Zinc Oxide nanowires to produce piezoelectric potential. Then on the basis of piezoelectric effect, the potential can be increased or decreased the effect of SBH link interface the carrier transportation, so that change the properties of nanowire-based devices. In addition, making specific hybridization between probe complementary target cDNA and nanowire adsorbed single-stranded DNA (the ssDNA), the device can achieve selective detection function.       The experimental results of this work showed that, when the compressive strain applied to the Zinc Oxide nanowire-based DNA sensor became -0.59%, the relative value of the current response increased by 454%. This fully illustrated that the modified method using a piezoelectric device electronics effect can significantly improve the detection performance of the Schottky contact type ZnO nanowire based DNA sensor.
