Water is able to maintain its local structure for unexpectedly long time - VIDEO PDF Print E-mail

Ultrafast lasers have helped the German physicist to figure out that the water is able to maintain its local structure for unexpectedly long time, in particular explains its unusual properties as the "universal solvent," according to an article published in the journal Nature Communications. "Approximately 71% of the Earth's surface is covered with water, and almost all biological and chemical reactions on the planet occur in the water or on the boundary between water and air in the ocean or in the clouds. Understanding how water behaves on a molecular level, it is imperative for us . We found that the water can not be considered as a whole, and that inside it there are special local structures, "- said Michael Bonn (Mischa Bonn) from the Institute for the study of polymers in Mainz (Germany). Bonn and his colleagues found that the water is similar in structure to a mosaic of relatively stable and ever-changing local "groups" of several water molecules, having studied the local structure of the water with the help of a set of ultra-fast lasers and infrared spectroscopy. As explained by scientists, physicists for a long time know of the existence of local structures - a relatively stable association of several molecules of water, but so far all the researchers believe that they have, in fact, no "memory" and that they fall within a very short time - a tenth of a picoseconds (a trillionth of a second). Observing the changes in hydrogen bonds between single molecules of water, a group of Bonn found that in fact these structures retain their shape and memory on the order of longer - for more than one picosecond. This finding, according to physics, radically changing the way scientists look at the water - a long "memory" of water should greatly affect how it behaves as a medium in which chemical reactions occur. This, according to Bonn and his colleagues could explain why water is the "universal solvent" and has a number of unusual properties.
