What is Chitosan?

Chitosan is a natural polymer extracted from the shells of shrimp and crabs. Chitosan is a polysaccharide (long chain of sugars) and has a known metabolic pathway. That means any chitosan left in the body is broken down by the bodies normal enzymes and converted into materials routinely present in t…

Alumina chemical compound

Some alumina is still produced by melting bauxite in an electric furnace, in a process devised for the abrasives industry early in the 20th century, but most is now extracted from bauxite through the Bayer process, which was developed for the aluminum industry in 1888. In the Bayer process bauxite i…

How Does Fluoride Protect Teeth?

Fluoride benefits both children and adults. Here's how: Before teeth break through the gums, the fluoride taken in from foods, beverages and dietary supplements makes tooth enamel (the hard surface of the tooth) stronger, making it easier to resist tooth decay. This provides what is called a "system…

Structure of praseodymium oxide

Praseodymium oxide, also known as praseodymia, is a dark brown powder which is insoluble in water and only soluble in strong acid. Praseodymium oxide is stable under normal temperatures and pressures. It is a rare earth oxide compound, which is a basic anhydride and can therefore react with acids an…

Tellurium properties

Crystalline tellurium has a silvery-white appearance, and when pure it exhibits a metallic luster. It is brittle and easily pulverized. Amorphous tellurium is found by precipitating tellurium from a solution of telluric or tellurous acid. Whether this form is truly amorphous, or made of minute cryst…

Silicon around us

Silicon is probably essential in higher plants and possibly in mammals. Diatoms, some protozoans, some sponges and some plants use silicon dioxide (SiO2) as a structural material. Silicon is known to be required by chicks and rats for the growth and development of the skeleton. Silicon is not partic…

About potassium formate

Potassium formate is a chemical compound useful in the production of potassium metal and in the petroleum and gas industry, often in aqueous solution (alone or in admixture with cesium formate), to produce a high-density brine that respects The environment that can be used Aa heat transfer fluid. Po…

Graphite oxide with graphene oxide

  The process of converting graphite oxide to graphene oxide can ultimately be very damaging to the various layers of graphene, which has other consequences when reducing the compound (explanation to follow). The process of oxidizing graphite to graphite oxide already damages the individual graphene…
