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 »

Materials science, together with the science of chemistry, examines many interesting materials. One of the most commonly used and most well known is a material known as steel.
Steel is a basically a material that, in most cases, contains up to 5% of carbon that, in the combination with iron, forms a very hard iron carbide. 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.

Chemistry behind matches
Posted by Admin in Uncategorized on January 3rd, 2010
I know that today not many people use matches any more, but some maybe ask themselves: What is the chemical side of matches and their ignition? Today’s matches are so-called safety matches because they tend not to ignite as easy as the original ones. The coating on a match contains glass powder, and red phosphorus.

Chemical substances that can change coloration
Posted by Admin in Uncategorized on January 2nd, 2010
In chemistry as a science, compounds that change color in relation to the amount of water that they contain in themselves are quite common and very well known (often this type of water is called water of crystallization because it is basically incorporated in the crystal lattice of a substance). Among others, we’ll list the example of cobalt chloride. When it is dry it has a distinct blue color, and when it absorbs enough water, the color changes from blue to pink.
