​Copper nanoparticles have attracted a lot of interest in recent years due to their interesting properties, low-cost preparation, and many potential applications in catalysis, cooling fluids, or conductive inks. In this study, copper nanoparticles were synthesized by chemical reduction of copper sulfate CuSO4 and sodium borohydride NaBH ₄ in water without inert gas protection.

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).

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.

Silver nanoparticles (AgNPs) have been extensively used as a potent reagent to enhance the Raman scattering of surface-enhanced Raman spectroscopy (SERS) due to their excellent stability and enhancing properties. In a recent publication by Nano Convergence, a more eco-friendly and efficient method of in-situ manufacturing of SERS substrates with AgNPs has been reported.

In the fields of materials science, catalysis, energy and environment, specific surface area is one of the important parameters for measuring material performance. The adsorption efficiency of activated carbon, the activity of catalysts, and the energy storage performance of electrode materials are often closely related to their surface area. The most widely used surface area measurement method currently is BET specific surface area testing. This article will provide a detailed analysis of BET testing from several aspects, including principles, sample preparation, data processing, and precautions.

SAT NANO is a leading supplier of high-quality nanoscale zinc oxide powder. Our products come in two sizes, 10-20 nm and 30 nm. Besides, we have recently developed an innovative surface modification method that improves the stability and dispersibility of our nanoscale zinc oxide powder. This method is effective in converting the surface of the powder from hydrophilic to hydrophobic, thus reducing the agglomeration of particles and enhancing their performance in various applications.
