Aerosol

humans, plants and animals from harmful ultra violet rays. Without the ozone layer it wouldn’t be possible for life on earth to exist. The cause of the ozone depletion is Cholorofluorocarbons (CFCs), Halons and Freons which are gases commonly found in aerosol cans. Many electronic appliances release these gases as well. Chlorine is the common ingredient in these gases and is the main cause behind the depletion of the ozone layer. CFC’s have accounted for about 80% of ozone depletion (Causes).…

2. Basic theories and principles 2.1 Chemical vapor deposition 2.1.1 Definition of chemical vapor deposition Chemical vapor deposition (CVD) is a versatile process which is widely applied to produce coatings, powders, fibers and monolithic components [1]. Applying the chemical vapor deposition, it is possible to produce alloy and compounds of metals and nonmetal materials. Chemical vapor deposition can be defined as the deposition of a solid on a heated surface from a chemical reaction in the…
