Infrared spectroscopy: It looks at how much light has been consumed. When a molecule absorbs light of a specific wavelength, we know what functional groups are inside it. Raman spectroscopy: It looks at how much light has been deflected. A laser beam is applied to analyze how much the light bounced back has changed, in order to determine the molecular structure.

​As a leading provider of high-quality PVP-coated nanoparticles, SAT NANO understands the need to remove PVP coating for various applications. PVP or polyvinylpyrrolidone is a polymer widely used to coat nanoparticles due to its superior solubility and stability. However, the PVP coating can interfere with the nanoparticles' surface reactivity, causing challenges in some applications. This article will discuss the different methods to remove PVP coating from PVP-coated nanoparticles.

Antibiotics refer to drugs that can inhibit bacterial growth, damage their living environment, and effectively and continuously exert their effects. Antibacterial agents are divided into two categories: organic antibacterial agents and inorganic antibacterial agents. Among them, organic antibacterial agents include natural and synthetic types, while inorganic antibacterial agents mainly include metals, metal ions, and oxides. The commonly referred to antibacterial measures include inhibition, killing, elimination of toxins secreted by bacteria, and prevention. Due to the strong thermal stability, long-lasting functionality, and safety and reliability of inorganic antibacterial agents, coupled with the development of ultra-fine technology in recent years, nanoscale inorganic antibacterial agents can be mass-produced and blended or composite into chemical fibers, ensuring the industrialization of antibacterial chemical fibers.

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.

Scanning electron microscopy can be divided into thermal electron emission type and field emission type according to the different ways of electron generation. The filament used for thermal electron emission type is mainly tungsten filament electron microscopy. Field emission type The distinction between hot field emission and cold field emission.
