Chemistry is the science that is all about the composition , structure , properties of matter , the changes suffered by it during chemical reactions and their relation to power. Chemistry hashabituallytitled the central science because, it is the bridge between other sciences such as physics and natural sciences such as geology and biology . It is considered as natural science along with Physics and Mathematics subjects. It experienced major theoretical and methodological development during the twentieth century, especially the establishment of quantum mechanics , spectroscopic methods and methodology of organic synthesis that boosted the discovery of new drugs. The analysis of chemical structure of molecule using deoxyribonucleic acid and sophistication of existing theories has also undergone development.
Areas of study in chemistry
When it comes to the subject, it is an insight into material composition, material groups and details about how to give material processes to nature. Chemical changes in the animate and inanimate nature are also based on chemical reactions and should be recognized. Similarly, from the scientific findings, for the understanding of modern technology lead to the introduction of new products. These made a significant contribution towards the improvement of living conditions of the people. The chemistry teaching also serves to educate the students to empower consumers. It is designed for this reason, according to curricula (curricula) and pedagogical approaches.
History of chemistry
- There are two main schools in natural philosophy elaborated by the Greeks. Democritus argued that the nature was composed of indivisible particles (the atoms ) that join and separate in an empty space, while Aristotle assumed the continuous structure of the material resulting from the combination of elements of water , air , earth and fire.
- Between II and V century AD developments at Alexandria s alchemy or former chemistry retained the origins that philosophical combined with a strong esoteric . The sixteenth century took its autonomy. The branch is defined as astrochemistry. The major contributorswere from Paracelsus and Jean Baptiste van Helmont. He had set himself to correlate the processes related to chemistry that occur within the human body with disease states and possible remedies.
- The basis for the development of modernization of chemistry raised during the seventeenth century with the first definition of the reactions related to chemistry (IntyrociniumChymicum of Jean Beguin ). The gradual development of the experimental method has been the next development. Thanks to several scientists like Robert Boyle . In 1807 JÃ¶ns Jacob Berzelius was the first to use the term "organic chemistry " in reference to the subject that characterized the compounds produced from the animal kingdom. They are opposed to those from the mineral and relevance of inorganic chemistry. Friedrich Wöhler in 1828 opposed this theory to demonstrate that organic compounds can also be obtained by synthesis in the laboratory. He was able to synthesize the urea from inorganic substances.
The researcher in chemistry
The pioneer names in chemistry are Theodore L. Brown, H. Eugene Lemay, Bruce Edward Bursten, H. Lemay, Carsten Reinhardt., etc.
There are some applications of chemistry which leads to research and development listed below;
Chemistry & Industry: : The chemical industry is responsible for the synthesis of large-scale chemicals for various purposes. Optimizing the ratio cost / benefit of the entire production cycle in chemistry is vastly dependent on the industries. Particularly by providing the appropriate raw materials through a set of processes carried out in a chemical plant,one can producesemi-finished or finished products to meet the specifications and technical requirements for their practical use.
Chemistry and medicine: The pharmaceutical chemistry is the field of research for the synthesis and application of new therapeutic drugs. This is the bases of the theoretical study and the physico-chemical properties of the molecules. The patterns of drug interaction with the body also can be altered/modified though pharmaceutical chemistry.
Chemistry and Technology: The use of chemical and physico-chemical techniques allows material science to study and characterize the structure and properties of the materials. The process is carried out to ensure the adequacy of the standard usage to develop new materials or to improve those already existing. The polymer chemistry focuses its activities on the mechanisms of polymerization and on the relationship between the structure and characteristics of the polymers . The electroplating and phosphating are examples of processes related to chemistry used for protection from corrosion. These methods may be mentioned as special paints and coatings which can confer particular characteristics to the materials. The solid-state chemistry among other fields of application has been actively involved in the synthesis of semiconductor innovative. This is intended for different technological applications. The development of supra-molecular chemistry plays a fundamental role for nanotechnology by allowing the synthesis of molecular devices such as Nano machines.
Chemistry and Environment: The increasing sensitivity to a low environmental impact and the need to implement policies to sustainable development has led to the emergence of so-called green chemistry . This discipline of chemistry aims to reduce the impact of chemical processes by putting into practice concepts such as the use of raw materials derived from renewable resources , reduction of waste and waste, and the use of compounds like biosostenibili which are environmentally sustainable . On the other hand, the environmental chemistry also focuses on the study of chemistry and biochemistry. Both are environment related fields and are about the chemistry of freshwater, soil, marine and the atmosphere .
Chemistry and Cultural Heritage: The chemistry applied to cultural heritage is in charge of the materials used in the field of artistic and analytical techniques. Non-invasive are used for instrumental analysis on the works of art.
