Recently, research teams from Sandia National Laboratories and the University of Toronto made groundbreaking breakthroughs in miniature terahertz sources, and succeeded in increasing the power output of terahertz lasers by 80%. It is expected that in industry Imaging and chemical detection and other fields have been widely used. The project is now favored by NASA to measure oxygen content to explore interstellar media components. Due to the terahertz laser source emitting laser light in the opposite direction, resulting in its actual output efficiency is low, at least half of the energy was wasted, making the application is limited. In order to solve this problem, the research team adopted a new structural design. The use of quantum cascade laser to form a "standing wave" and to add cracks in the standing wave, making the terahertz laser can burst out of the waveguide, and coincide with the opposite direction of the band to increase the laser intensity. The device successfully led 80% of the laser intensity in the right direction. At the same time, the design also solves the problem of laser synthetic loss caused by traditional mirrors and is very important for improving the efficiency of the terahertz laser. This design is used to further increase the power of the THz laser, but some of it is still wasted. The future also need to improve the overall performance of the laser beam, resulting in higher quality laser beam.
Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles, and films. It is a PVC heat Stabilizer with good lubricity and good light and heat stability. In plastic PVC pipes, stearic acid helps prevent "coking" during processing. It is an effective thermal stabilizer added in the processing of PVC films, and can prevent finished films caused by excessive exposure to sulfides.
Mainly used to produce stearates: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, potassium stearate.

Widely used to make cosmetics, plastic cold-resistant plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and others Organic chemicals.
In addition, it can also be used as a solvent for oil-soluble pigments, a crayon slip agent, a wax paper polish, and an emulsifier for glyceryl stearate.
The product is used as a lubricant, defoamer and food additives in the food industry as a raw material for glyceryl stearate, sorbitan stearate, and sucrose esters. Used as the raw material of additives and the raw material of daily chemical products.
