Aportaciones cientificas que han dado un gran impacto a la sociedad

LEO HENDRIK BAEKELAND
 I reach one of the first plastics made from synthetic components (although phenol can be extracted from biological sources), Bakelite was used for its electrically nonconductive and heat-resistant properties in radio and telephone casings and electrical insulators, and also in such diverse products as kitchenware, jewellery, pipe stems, and children's toys.

This contribution of cracked petrol consists of aliphatic hydrocarbons obtained by the fractional distillation of petroleum, enhanced with iso-octane or the aromatic hydrocarbons toluene and benzene to increase its octane rating. This contribution has been of great help since to facilitated the displacement in means of transport to the human being

The first thermal cracking method, the Shukhov cracking process, was invented by .William Merriam Burton developed one of the earliest thermal cracking processes in 1912 which operated at 700 - 750 °F (370 - 400 °C) Insulin is a hormone that is central to regulating energy and glucose metabolism in the body. Insulin causes cells in the liver, muscle, and fat tissue to take up glucose from the blood, storing it as glycogen in the liver and muscle.

Neoprene in general has good chemical stability, and maintains flexibility over a wide temperature range. It is used in a wide variety of applications, such as laptop sleeves, orthopedic braces (wrist, knee, etc.), electricalinsulation, liquid and sheet applied elastomeric membranes or flashings, and car fan belts.

Alexander Fleming



Penicillin antibiotics are historically significant because they are the first drugs that were effective against many previously serious diseases such as syphilis and Staphylococcus infections. Penicillins are still widely used today, though many types of bacteria are now resistant.


This scientist I contribute the sulfamia that
 It is a chemical substance derived from the this sulfonamida uses as antibiotic in the treatment of infectious diseases for his action bacteriostáticas
Cortisone has been a great contribution since it has helped many persons. It is used to treat a variety of ailments and can be administered intravenously, orally, intraarticularly, or cutaneously. Cortisone suppresses the immune system, thus reducing inflammation and attendant pain and swelling at the site of the injury

These scientific contributions have been helpful to human being. Thanks to this there have arisen innovations that have changed and facilitated our lives. We can observe some of the scientists' images that they offered to us a big contribution that has impact to the job of people so that they have contributed with the socioeconomic development giving employments to thousands of persons and improving the quality level of life of all us.
