The growth of Nanotechnology Applications in the World

الملخص

Nanotechnology is the science and creation of materials at a molecular level. Nanotechnology applications are used in medicine, chemistry, the environment, energy companies, and communication. Whether it is through nanotechnology education or nanotechnology application, this science continues to evolve and find more uses in everyday life. The use of nanotechnologies in medicine has provided many medical breakthrough. Some of the medical nanotechnology applications are for diagnostics. These are used to assist in identifying DNA and helping detect genetic sequences.  Other uses of nanotechnology in medicine are in drug delivery and tissue engineering. Drug delivery can help in cancer treatments by
administering drugs via implant versus the traditional injections. Tissue engineering is a new nanotechnology and involves repairing or artificially reproducing damaged tissues.Using molecular nanotechnology in chemistry and the environment has already resulted in positive benefits. Chemical catalysis is a process of reducing pollutants using a reagent or catalyst. This can be especially helpful if used in vehicle fuel cells or catalytic converters to reduce car emissions. Filtration is another field of nanotechnology applications that can help the environment. Extremely small holes in the filtration, known as nanofiltration, remove ions for wastewater treatment or air purification.   . The main objective of the filter is the ability to hold dust filter so efficiency is a key factor in its choice, especially in the ability to hold a very small particle filter as well as the age factor and the environment on the other. There are many sources of dust including dust resulting from manufacturing processes of cement that harmful to workers and the surrounding environment. Technology is the use of filters of
effective techniques in the types of dust collectors, known especially after the use of nanotechnology in various fields and applications to achieve the advantages of saving energy and costs. This paper discusses the process of manufacturing nanofibers, and the performance of the filter in terms of efficiency and design specifications and variables. The primary
function of filtration systems is to reduce the rate of emissions, both gaseous or solids where the greatest possible efficiency standards by adding materials such as carbon, glass, and Kevlar fibers to the polymer composed of composite materials that have superior structural characteristics of the most important high modulus and strength to weight ratios and mechanical properties. In this paper the use of reinforced materials using nanocarbon fiber is investigated where improvement of the efficiency of nanofilters by more than 20 ℅ is achieved. Keywords—Nano Technology, filter efficiency, nanofiber filter media, dust collectors, high modulus and strength.
