Physical and Nuclear Chemistry

Physical Chemistry deals with the structure of matter and the energy changes that occur during physical and chemical changes of matter. This field provides a theoretical basis for the chemical observations of the other subdivision of other subdivisions. Analytical chemistry is concerned with the identification of chemical substances, the determination of the amounts of substances present in a mixture, and the separation of mixture onto their individual components.

Special subdivisions of chemistry are now recognized the account for knowledge at the interface of chemistry and other physical sciences. For example, recent research has involved the chemical origin of life, reactions between simple molecules at low pressures to form such complex organic molecules as proteins found in living organisms.

Astrochemistry is the interdisciplinary physical science that studies the origin and interaction of the chemical constituents, especially interstellar matter, in the universe, Geochemistry is concerned with the chemical aspect of geology, for instance, the improvement of ore processing, coal utilization, shale oil recovery, and the use of chemicals to extract oil from wells that are considered dry by ordinary standards.

Nuclear chemistry deals with natural and induced transformations of the atomic nucleus. Studied in this field now center on the safe and efficient use of nuclear power and the disposal of nuclear wastes. Radiochemistry deals with radioactive isotopes to further the understanding of chemical and biochemical systems. Environmental chemistry is a subdivision that has as its subject the impact of various elements and compounds on the exosphere.

Removing Iron Rust Using Electrochemical Process

One way to remove iron rust is by electrochemical process. The iron or metal that will be rusted is given a negative charge and the other electrode means that it is positively charged, so the rust will be released from the metal because negative ions will come out of the metal and go to the positive electrode. If the process is continued, the iron may become shiny, not because it is coated in therapy because the surface is partly faded. This is because the iron functions as a negative electrode, where the ions on the surface of the iron will decay and dissolve into the chemical solution. To give an idea of this process, see the following video:

Viscose Fiber Production Process

Viscose fiber is a base material for textile industry. The first production of this kind product is in Indian than spread over the Europe and United States also in South Asia Country like in Indonesia. Viscose fiber is produced to anticipate the shortage of natural yarn for raw material to produce yarn in textile industries, beside synthetic yarn as replace natural cotton to produce fabric. This one is a simple drawing of viscose fiber production process . Viscose fiber is used to substitute the using of cotton as raw material for textile industry. Beside of cotton availability will not enough to supply market demand in the future, also cotton just available on harvesting season. If people just depend on cotton to produce textile then people will shortage of raw material to produce textile. Using viscose fiber to fulfill of textile industry will not any shortage raw material, beside the price is lower than cotton, viscose fiber also have better quality compare with synthetic fiber fo
