There are several techniques that can be used to test the purity of a powder. One common method is X-ray diffraction analysis (XRD), which can be used to identify and quantify the different crystalline phases in a powder.

Copper is different from metals such as aluminum and nickel in that it is difficult to form a dense and stable intrinsic passivation layer on its surface. Therefore, the exposed copper surface will be continuously oxidized and corroded by oxygen and water vapor in the air. The smaller the particle size and larger the specific surface area of copper powder, the easier it is to rapidly oxidize to produce products such as cuprous oxide (Cu2O) and copper oxide (CuO). This oxide insulation layer significantly reduces the conductivity of copper powder and hinders particle sintering connection, resulting in degradation of the performance of the conductive paste.

Our research at SAT NANO has identified several critical advantages. First, Boride Nanoparticle additives create a denser, more cohesive barrier against moisture and chemical penetration. Second, they dramatically improve abrasion resistance – often increasing it by 200-300% compared to standard coatings. Third, they maintain stability at temperatures exceeding 800°C, where traditional coatings would rapidly degrade.

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.

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.

The 14th Shenzhen International Thermally Conductive Materials and Equipment Exhibition, also known as CIME2025, is set to take place on June 4-6, 2025, at the Shenzhen International Convention and Exhibition Center. With an expansive exhibition area of 20,000 square meters, the event is expected to host 500 exhibitors, 30 academic presentations, and attract approximately 30,000 professional visitors. CIME, originating in Shenzhen in 2013, has evolved over the past decade into a prestigious industry event in the field of thermal management and thermally conductive materials, now hosting exhibitions in Shenzhen in June and in Shanghai in December.
