Nano-aluminum oxide is a widely used material, especially in the field of nanotechnology, due to its unique physicochemical properties such as high surface area, high thermal stability, and excellent catalytic activity. However, the surface properties of nano-aluminum oxide play an important role in its performance in many applications. Therefore, surface modification of nano-aluminum oxide is essential to improve its properties for specific applications. In this article, we discuss one of the effective surface modification methods of nano-aluminum oxide, which involves using a silane coupling agent (KH-560).

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.

Researchers have made a breakthrough in the development of carbon nanotube (CNT) reinforced aluminum composites by utilizing ultra-short CNTs with unique intra-crystalline dispersibility. The nanoscale carbon nanotubes are uniformly distributed within the ultra-fine aluminum grains. When compared with typical CNT/Al composites with inter-granular CNT dispersion, this intra-crystalline carbon nanotube/aluminum composite has a stronger ability to anchor and maintain dislocations, resulting in enhanced strength and ductility. This innovative intra-crystalline dispersal strategy provides a new avenue for developing strong and tough nanocarbon reinforced metal-based composite materials. The research has been published recently in a prestigious academic journal.

These nano powders can improve the biocompatibility, mechanical properties, bioactivity and degradability of bioceramics by adjusting the particle size and morphology, making them more suitable for biomedical applications. Of course, the specific selection of the types and applications of nano powders should take into account the characteristics of materials and specific application scenarios.

In conclusion, ultrafine powders offer an array of benefits, but their processing can be challenging. Surface coating is an effective solution for enhancing the properties of these powders, improving their performance, and extending their applicable scope. The methods discussed in this blog post- PVD, CVD, sol-gel, and polymer coatings- are just a few examples of the many surface coating options that are available for ultrafine powders. Whether you are in the pharmaceuticals, cosmetic, or electronic industry, surface coating could make the difference in the success of your product.

Powder dispersion is an essential process in many industries, including pharmaceuticals, food, and cosmetics. The dispersion quality of powders in liquid systems can affect their stability, performance, and functionality. Therefore, it is vital to characterize the dispersion effect of powder to ensure the quality of the final product. In this article, we will discuss different methods to characterize powder dispersion and their significance in assessing the quality of the dispersion.
