Ultra fine high-purity alumina is a cornerstone material in fields such as electronic information, new energy, high-end manufacturing, and biomedicine. Its application value lies in the precise control of purity, particle size, crystal form, and morphology. Purity determines the upper limit of performance, particle size determines sintering/dispersion/activity, and crystal structure determines functional characteristics. With the development of 5G, solid-state batteries, third-generation semiconductors, and biomedicine, the demand for 6N grade ultra-high purity, monodisperse nanoscale, and spherical alumina will continue to grow. This article discusses the practical applications of ultrafine and high-purity alumina powder.

The 16th China International Powder Metallurgy & Hard Alloy Exhibition, also known as PM CHINA, is the flagship event of the global powder metallurgy industry. Since its establishment in 2008, it has grown at an astonishing rate of 30% annually, from a few hundred square meters to a massive 40,000 square meters in 2023. With its extensive international reputation and global influence, PM CHINA has become a must-attend event for companies worldwide.

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.

Iron oxide nanoparticles are extensively studied for their use in medical applications due to their unique magnetic properties. However, one of the major concerns with the use of inorganic nanoparticles is their potential biotoxicity. Inorganic nanoparticles have a slow clearance kinetics that can pose a potential threat to their in vivo application. The clearance of nanoparticles from the body largely depends on the surface physicochemical properties rather than their size and shape.

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.

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.
