Surface hydroxyl engineering refers to the targeted regulation of the number, distribution, and chemical activity of hydroxyl (- OH) groups on the surface of materials through physical, chemical, or plasmonic means, in order to achieve precise adjustment of surface properties. Hydroxyl groups are the most common polar functional groups that can form hydrogen bonds, coordination bonds, or covalent bonds with water, metal ions, polymer chains, or biomolecules, significantly altering the hydrophilicity, surface energy, adsorption/catalytic activity, and biocompatibility of materials.

Nano boron carbide and ultrafine boron carbide powder were prepared by variable current laser ion vapor phase method. Boron carbide, also known as black diamond, has a molecular formula of B4C and is usually a gray black micro powder. It is one of the three hardest materials known (the other two being diamond and cubic boron nitride). Hard black glossy crystal. The hardness is lower than industrial diamond, but higher than silicon carbide. Compared to most pottery, it has lower fragility. Has a large thermal neutron capture cross-section. Strong chemical resistance. Not susceptible to corrosion by hydrogen fluoride and nitric acid. Dissolved in molten alkali but insoluble in water and acid.

Adding nanoparticles to ink and paint products is becoming increasingly popular in many industries, especially those concerned with print and packaging industries. One of the significant advantages of adding nanoparticles to ink and paint products is their ability to protect against UV rays. In this article, we will explore what nanoparticles can be added to ink and paint to provide effective UV protection and introduce a reliable supplier of premium quality nanopowders.

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.

When making certain products, such as paints, coatings and electronics, it is necessary to use nanopowders. However, these powders can be difficult to disperse and can clump together, causing issues with product quality. To combat this problem, dispersants are used to effectively separate and disperse these powders. In this article, we will discuss the use and benefits of dispersants for the dispersion of nanopowders.

​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.
