In nature, there are a lot of elements, these elements are invisible, but they have a very important position.These elements are constantly in the chemical reaction, thus building the world we see now.。
Arsenic, commonly known as arsenic, is a kind of metallic element in the periodic table of the chemical elements in the fourth cycle, VA, atomic number 33, symbol As, elemental arsenic and arsenic in grey black and yellow as the three allotropic forms. Arsenic is widely found in nature, and hundreds of arsenic minerals have been discovered. Arsenic and its compounds are used in pesticides, herbicides, pesticides, and many kinds of alloys. The compound is called arsenic trioxide arsenic is a highly toxic substance.

The Saviour of stomach-Pirenzepine
The irregular eating habits, because of various reasons, leading to gastric or duodenal ulcer, therefore, the use of Pirenzepine, can reduce gastric and duodenal ulcer pain, reduce the amount of antiacids, make people recover faster.
Pirenzepine is a selective anticholinergic drugs and anticholinergic drugs, with high affinity, and myocardial M receptor and vascular smooth muscle, low affinity, salivary glands, so the general application of the dose, not only can inhibit gastric acid and other drugs anticholinergic side effects on digestive tract secretion of students. Smooth muscle, heart, salivary gland and bladder muscle. The increase of dose can inhibit the secretion of saliva, only a large dose can inhibit gastrointestinal smooth muscle, causing tachycardia.

Development prospect of nanometer metal powder
With the development of the times, the progress of the society and the updating of the industrial materials, nano metal powder is one of the modern industrial materials.
As a new type of functional material, metal nanoparticles have unique properties and have been playing an important role in modern industry. In this paper, the recent progress in the research of nano metal particles, the basic effects, the characterization, application, preparation and surface modification of nano metal particles are reviewed.
Due to the frequent use of nano metal powder in industrial production, is a very good industrial raw materials, it can be predicted that the prospect of nano metal powder is extremely open.

Development prospects of metallic silicon
Name:Silicon
Also called silicon metal silicon or silicon, is mainly used as the additive non ferrous alloy. Silicon metal is composed of quartz and coke in the electric furnace smelting products, the principal component of silicon content is about 98% in recent years, the content of Si of 99.99% is also included in the inside, the remaining impurities in silicon metal for iron, aluminum, calcium etc..
Smelting metal silicon is a high energy consuming production, silicon metal production in China has been long-standing, with the tightening of national energy policy and energy saving, development, and promotion of new energy, metal smelting silicon has become the primary products and processes, many domestic enterprises in the construction of new energy metal silicon, polycrystalline silicon, monocrystalline silicon, circulation the solar cell industry chain and a series of applications, the next few years will inevitably affect the development of our entire field of energy and new energy.

What is the use of Aggrecanases
A lot of doctors in the Department of orthopedics when the patient medication, will appear in the proteoglycan enzyme, then why do you need this component?
Matrix Aggrecanases(polysaccharide) is the main branch of the polysaccharide, which is the main component of the covalent binding of sugar and peptide complexes. Covalently linked polysaccharides consist of a polysaccharide protein substance sketch of chitosan composite protein and sugar content. It is a major component of connective tissue, by specialized cells or fibroblasts and chondrocytes of connective tissue. Its main function is as a connective tissue (collagen and elastin) fibers embedded in the matrix or coating, can also be used as cushion tissue, so that smooth joints.
