Materials Science – Self Darkening Materials
Posted by Admin in Uncategorized on January 19th, 2010
Self darkening glass has been and still is one of the more interesting inventions that came from the domain of chemistry as a science, along with materials science. Although today there are also lenses made of plastic, here we will mention the early versions of lenses used in optics, that were bassed on glass as the primary material.
This type of self darkening glass basically works by reacting to ultraviolet rays that come from the sun. Read the rest of this entry »

About The Process Of Cleaning Silver Jewelry
Posted by Admin in Uncategorized on January 13th, 2010
People often say that gold is the king among the elements in chemistry, but the same could be said for silver as well. Silver is a metal that has the least electrical resistance of all metals amd conducts heat best, and it certainly has a high reflectivity in the infrared and visible part of the spectrum. During the melting process, this metal absorbs a large volume of oxygen that is released after when silver is cooled. Read the rest of this entry »

The chemical side of napalm
Posted by Admin in Uncategorized on January 6th, 2010
Napalm is a thickened composition based on gasoline into which substances are added in order to get a gelatine-like substance for military uses. It has been developed by the chemical department at Harvard. According to Louis Fieser, the name of napalm derives from the first letters of the names of the thickeners (naphtenic and palmitic acids), or coprecipitated aluminium salts of naphthenic and palmitic acids.
