In last year’s Nobel Prize in Chemistry went to scientists who studied the ribosome (intracellular particles composed of ribosomal RNA and proteins). In 2008, it received biologists uncover and explore the green fluorescent protein.
Nobel Prize in Chemistry was awarded this year’s Richard Hake (Richard F.Heck), Ei-ichi Negishi (Ei-ichi Negishi) and Akira Suzuki (Akira Suzuki) for the development of the chemical agent to improve opportunities for the creation of carbon-based molecules, such as complex as those created naturally.
This year the prize in chemistry found its winners among scholars engaged in organic chemistry, which developed the reaction, allowing the carbon molecules connected together using palladium as a catalyst.
In order to create these complex chemicals, chemists had to join carbon atoms together. It should be noted that the carbon is a solid, durable material and therefore easy carbon atoms react with each other. First tools were allowed to mix only simple organic molecule. With palladium-catalyzed cross-coupling, the scientists were able to combine the carbon atoms in the complex molecule.
Method palladium catalyzed cross-coupling is used in research worldwide, as well as in commercial production, such as pharmaceuticals and molecules used in the electronics industry.
Through these chemical reactions, chemists succeeded in synthesizing anticancer drug such as paclitaxel, also known as a drug called Taxol, which previously could be extracted only from the yew tree, pesticides, such as, prosulfuron and Panama poison frog called pumiliotoksin that kill mosquitos.
The common thread in all three reactions that improves palladium combining organic compounds through formation of new chemical bond connecting the two carbon atoms. Like the chemical matchmaker, the surface of palladium "captures" both the substance and brings them so that they can react with each other.
And moving from chemical to him, it should be recalled that the Nobel Prize for Literature went to Peruvian author Mario Vargas Llosa (Mario Vargas Llosa), "for his cartography of structures of power and the powerful images of resistance, revolt and defeat personality" on NobelPrize. org Modern news widgets to help you follow the course of the global economy.
