The most powerful propriety of laser dyes is their tunability band laser emission which gives a varity of applications in many fields. Laser dyes are used efficiently in the isotope separation field. They also have applications in biology such that they modify the DNA by irradiation with ultraviolet light to prevent genetic mutations. The most successful, advanced and Continue reading »

An atomic theory is a model developed to explain the properties and behaviors of atoms. As with any scientific theory, an atomic theory is based on scientific evidence available at any given time and serves to suggest future lines of research about atoms. The concept of an atom can be traced to debates among Greek philosophers that took place around the sixth century B.C. One of the questions that interested these thinkers was the nature of matte Continue reading »

US market to double by 2011
 
 Although the hype surrounding polymer nanocomposites has been in full-throttle for over a decade, so far the market for these new materials has been relatively slow to develop. However, as commercial interest has moved beyond pilot programs and niche applications, it appears that nanocomposites are finally ready for a breakthrough in markets such as motor vehicles and packaging. By 2011, nanocomposites d Continue reading »

You breathe air made up of atoms, eat foods composed of atoms and drink water made up of atoms—with a body that itself consists of atoms. The objects you see around you are actually nothing more than photons striking the electrons belonging to the atoms in your eyes.

And what about the things you touch and feel? Those too—hard and soft, rough and smooth, cold or hot—consist of the atoms in your skin interacting on the atoms Continue reading »
