Chemistry, along with chemical engineering have given us various products based on many different chemicals that we, not rarely, use on a daily basis. Many of you are probably not aware that you use some pretty interesting compounds relatively often. Here we will mention two relatively common chemicals: hydrogen peroxide and acetone. (more…)
There are three basic states of matter that are often described in the sciences of chemistry and physics – solid, liquid and gaseous state. However, lately, there is another special state of matter that is often referred to as the fourth state of matter, thereby expanding the mentioned list.
Plasma, in the most basic definition, is considered to be ionized gas. (more…)
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. (more…)
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. (more…)
Materials science, together with 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. (more…)
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.

There are many interesting everyday situations that can be explained with the help of the science of chemistry. One of them is the common fogging of glass. Air at any time contains a certain amount of water in the form of water vapor. (more…)
