In the current era of miniaturization of electronic devices, rapid development of the new energy industry, and continuous improvement of LED lighting power, "heat dissipation" has become a core bottleneck restricting product performance upgrades and lifespan extensions. Traditional thermal conductive materials either have insufficient thermal conductivity efficiency, poor compatibility, and are prone to settling, making it difficult to meet the needs of high demand scenarios. Nano aluminum oxide, with its unique nanoscale structure and excellent thermal conductivity, is becoming a "performance breakthrough" in the field of thermal conductivity, providing efficient heat dissipation solutions for multiple industries such as electronics, new energy, and lighting.

SAT NANO is specialized in manufacturing top-quality Zinc Ferrite Nanopowder, and their production process is innovative. This revolutionary method, known as "pulsed laser ablation" is a green and environment-friendly technique that converts Zinc Ferrite Target into powder form using a high-energy laser. Compared to the traditional methods such as hydrothermal, co-precipitation, and microwave-assisted methods, the pulsed laser ablation method is faster, greener as it doesn't produce waste and the produced nanomaterial is pure with fewer defects.

On unsaturated metal sites of metal oxides or semiconductor oxides (such as Ti4+, Fe3+), water molecules first adsorb in molecular form, followed by O-H bond cleavage, resulting in bridge or terminal hydroxyl groups (M-OH) and surface hydrogen atoms. The thermodynamic driving force of this process comes from the strong Lewis acidity of metal ions, making water molecules easy to dissociate. Both experiments and DFT calculations indicate that surfaces covered with low oxygen tend to dissociate and adsorb, while surfaces covered with high oxygen tend to adsorb molecules.

BN and AlN are both exceptional materials that offer high thermal conductivity and unique physical properties for various engineering applications. BN's thermal conductivity is higher than AlN, making BN a superior choice for space applications, high-temperature electronics, and thermal management applications.

Nano boron carbide and ultrafine boron carbide powder were prepared by variable current laser ion vapor phase method. Boron carbide, also known as black diamond, has a molecular formula of B4C and is usually a gray black micro powder. It is one of the three hardest materials known (the other two being diamond and cubic boron nitride). Hard black glossy crystal. The hardness is lower than industrial diamond, but higher than silicon carbide. Compared to most pottery, it has lower fragility. Has a large thermal neutron capture cross-section. Strong chemical resistance. Not susceptible to corrosion by hydrogen fluoride and nitric acid. Dissolved in molten alkali but insoluble in water and acid.
