With the development of nanotechnology, tungsten disulfide nanomaterials (WS2NM) have become a new choice for optical biosensors.

Gold nanoparticles or AuNPs are only a fraction of the size of human hair and are less than 100 nm in diameter.

A lubricant is a substance that helps to reduce friction between surfaces that come into contact with each other, resulting in a reduction in the amount of heat generated as the surface moves.

Chinese researchers have recently reported an innovative mechanical process for controllable stripping of hexagonal boron nitride nanowires (h-BNNSs). This method is called "water ice triggered stripping process".

Silicon nitride ceramic is a kind of synthetic material with strong covalent bond force between silicon and nitrogen atoms in its structure, so it has the characteristics of high strength, high hardness, corrosion resistance, oxidation resistance, wear resistance and good thermal shock resistance.

Silicon nitride is considered to be a very important engineering ceramic because it is suitable for many different forms, each of which has unique characteristics.

Silicon carbide is used to make bulletproof armor.

Scientists use monolayer molybdenum disulfide (MoS2) to create a flexible sensor that solves the problem of real-time temperature detection sensitivity, which can sense temperature changes in a few microseconds, about 100 times faster than commonly used thin-film metal detectors.
