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.

Scanning Electron Microscope (SEM) is a high-resolution characterization and analysis technique that uses a focused electron beam to scan the surface of a sample point by point, excite secondary electron SE, backscattered electron BSE, characteristic X-rays and other signals, and image them, thereby achieving the microstructure, chemical composition and microstructure of the sample surface. This article will briefly introduce common problems in the SEM testing process, their causes, and corresponding solutions:

​The core reason why surface treatment is necessary for submicron high-purity alumina micro powder (usually with a particle size between 100nm and 1 μ m) is that its huge specific surface area leads to extremely high surface energy. This physical property causes it to exhibit serious' side effects' in its untreated state. Submicron high-purity alumina micro powder is prone to agglomeration due to its small particle size, large specific surface area, and high surface energy, which is a common problem in its application. To solve this problem, it is necessary to comprehensively consider the three dimensions of physics, chemistry, and technology, and choose the most suitable depolymerization solution.

Synthesis produces single crystal grains or amorphous spheres, each of them a primary particle. Let several of them touch and bond, and they form a larger unit — an agglomerate. Agglomerates differ in how firmly they are held together. In a soft agglomerate the primary particles are bound mainly by weak physical forces such as van der Waals attraction, and ultrasound or another source of external energy can separate them again. In a hard agglomerate the contact points have been welded shut by chemical bonds or by sintering, and no ordinary dispersion step will prise them apart.

The 17th International Surface Treatment, Electroplating and Coating Exhibition will be held from May 15th to 17th at the Poly World Trade Center Expo in Guangzhou in 2024. The exhibition has always been in line with the development needs of the industry, leading the innovation of surface treatment technology and industrial upgrades.

Metal nanoparticles are small, and their properties can differ from bulk forms of the same material. One key difference that has puzzled scientists and engineers for many years is why metal nanoparticles frequently exhibit intense black coloring. In this article, we will explore this phenomenon and learn how SAT NANO is using its expertise to provide superior metal nanopowders to its customers.
