Researchers have recently developed a novel light-responsive double network hydrogel based on methyl acrylated peptide nanofibers (PNFMA) with high biocompatibility, excellent biodegradability, and multifunctionality for the modulation of cancer cells in photothermal therapy.

​Nano silver powder refers to metallic silver elemental powder with a particle size ranging from 1-100 nanometers (nm), also commonly known as nano silver or silver nanoparticles. Due to its unique physical and chemical properties, it plays a key role in multiple cutting-edge fields such as electronics, medicine, catalysis, and more. The particle size distribution range of nano silver powder is narrow, with commonly used particle sizes of 20nm, 50nm, 80nm, and 100nm. The purity of nano silver powder can reach 99.99%. We can also supply nano silver powder and aqueous dispersion.

As nanotechnology continues to reshape modern industries, Bismuth Oxide Nanopowder has emerged as a highly promising nanomaterial due to its exceptional electrical, optical, catalytic, and chemical properties. As a leading nanomaterial supplier, SAT NANO provides high-purity Bismuth Oxide Nanopowder designed for applications in energy storage, photocatalysis, sensors, electronics, environmental remediation, and advanced ceramics.

As one of the most important characterization parameters of nano powder, particle size directly affects the physical and chemical properties of the powder, and then affects the performance of the final product. Therefore, its detection technology is an important tool for industrial production and quality management, and plays an irreplaceable role in improving product quality, reducing production costs, and ensuring product safety and effectiveness. This article will start from the principle and compare three common methods for powder particle size detection: electron microscopy, laser particle size analysis, and X-ray diffraction line width method, and analyze the advantages, disadvantages, and applicability of different particle size testing methods.

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.

As an important physical property of powders, specific surface area refers to the total surface area per unit mass of oxide powder. And its size is influenced by various factors. Firstly, particle size is an important factor affecting the specific surface area of powders. The smaller the particles, the larger the specific surface area. This is because the smaller the particle size, the larger the surface area of each individual particle, thereby increasing the total surface area per unit mass of powder.
