Nanosized aluminium powder is an innovative wonder material that has various unique properties that make it useful for many industrial applications. Its enhanced mechanical, thermal and catalytic properties offer opportunities to develop new materials and products with better performance. The synthesis of nanosized aluminium powder is now a developing field of research and promises bright prospects for the future.

​Why are d10, d50, and d90 key parameters used to describe the particle size distribution characteristics of particles in slurries (such as silver slurries). Here is a specific explanation:

With the development of integrated circuit (IC) technology, the scaling of silicon-based metal oxide semiconductor (MOS) field-effect transistors (FETs) is approaching their fundamental physical limits. Carbon nanotubes (CNTs) are considered promising materials in the post silicon era due to their atomic thickness and unique electrical properties, with the potential to improve transistor performance while reducing power consumption. High purity aligned carbon nanotubes (A-CNT) are an ideal choice for driving advanced ICs due to their high current density. However, when the channel length (Lch) decreases below 30nm, the performance of single gate (SG) A-CNT FET significantly decreases, mainly manifested as deteriorating switching characteristics and increased leakage current. This article aims to reveal the mechanism of performance degradation in A-CNT FET through theoretical and experimental research, and propose solutions.

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.

As a researcher with over two decades of experience in material science, I have seen firsthand the challenges that come with synthesizing consistent, high-quality metal oxide nanoparticle suspensions. The struggle is real—agglomeration, where those tiny, powerful particles stick together, can ruin the very properties we work so hard to achieve.

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.
