Open your mouth and align the teeth with a 3D scan, and the 3D printer can print a zirconia ceramic denture. Before the advent of 3D printing technology, people needed to bite out the dental membrane to make a denture, and then sent it to the factory for production, and repeated carving, the production cycle was longer, and 3D printing technology not only improved efficiency, but also greatly save...

In recent years, silver coated copper powder has been widely used, not only as the electrode of chip electronic components, but also in the fields of catalyst and electronic paste. At present, the electronic paste used in my country is basically micron-level pure silver powder, which is expensive and mainly imported. Micron sterling silver powder has the problem of particle sedimentation in the la...

Chemical modification and dispersion is to use the surface groups of nanoparticles to form chemical bonds with reactive organic compounds. The nanoparticles are soluble in organic media due to the branched chains or groups of organic compounds on the surface. dispersion in. There are usually two ways of chemical modification: one is to use the end groups of macromolecules to chemically react with ...

Nanoparticles have a special surface structure, which lacks adjacent coordinating atoms on the surface, and has high activity, so it is easy to agglomerate. Due to the strong self-absorption property among nanomaterial particles, the agglomeration of nanoparticles is inevitable. Aggregates can be divided into two types: hard agglomerates and soft agglomerates. The formation process of agglomerates...

Particle size: The size of the particles is called particle size, usually the particle size of spherical particles is expressed by diameter/particle size, and the particle size of cubic particles is expressed by side length. Particle size is the diameter of a particle. However, most of the particles in practice are irregular. Therefore, in order to describe the size of the particles more convenien...

Nanomaterials exhibit many exotic properties that traditional materials do not have. The first thing we need to know is that the nanometer (mainly refers to less than 100nm) of the composition of nanomaterials has four major effects: 1. Small size effect The boundary conditions of the crystal periodicity are destroyed; the atomic density near the surface layer of the amorphous nanoparticle decreas...

The size of the particles is called the particle size of the particles, which may also be referred to as particle size. Particle size or particle size refers to particle diameter. Of course, for non-spherical particles, the particle size is related to the measurement criteria and statistical methods, and the particle size can only be "equivalent". The percentage (or cumulative percentage) of parti...

Manganese dioxide (chemical formula: MnO2) is a black or brown solid, the most stable oxide of manganese, and is often found in pyrolusite and manganese nodules. Pylusite is the main mineral containing manganese; manganese nodules (submarine rock solids) also contain manganese. Manganese dioxide is mainly used to make dry batteries, such as carbon-zinc batteries and alkaline batteries; it is also ...
