leads up through the stem to the nozzle in the button. This allows the product
to be forced up the dip tube by the gas pressure in the can. The nozzle is
shaped to give a spray or a continuous stream.
To produce a fine mist, a propellant is used which mixes with the
product. The two leave the nozzle together and the propellant evaporates a soon
as it reaches the air, breaking the product in to tiny droplets. The same
technique used with a more viscous liquid and a wider nozzle results in a foam.
For a continuous stream of liquid or more viscous material, a nonmixing
propellant is used, and the dip tube reaches int .....

Lasers 3
Number of words: 809 | Number of pages: 3.... interested in the idea of building an optical maser, which soon received the name laser (light amplification by stimulated emission of radiation). Townes paired with Arthur Schawlow, two Soviets, Nikolai Basov and Aleksander Prokhorov, as well as Gordon Gould were all interested in developing a light-amplifying device. All of them knew that there were three essential ingredients in making a laser; a florescent material that would emit light when stimulated by radiation from an external energy source, two facing mirrors on the sides of the florescent material, and external energy source.
Theodore Maiman was the first to success .....

The only difference between these two sugars is that deoxyribose contains one oxygen atom less than ribose. Pentose sugars are essential because they are involved in linking different nucleotides together by condensation reactions.
The Nitrogen-Containing Bases
There are two types of bases found in nucleic acids. The purine bases have two nitrogen containing rings, while the pyrimidines have only one. In DNA the purines are adenine (A) and guanine (G) and the pyrimidines are cytosine (C) an .....
