Scientists have found in a Siberian coal materials that do not exist anywhere else in the world.
Currently, a team of researchers from Canada and the Russian Federation has determined the crystal structure of zhemchuzhnikovita to find it in the mines in Yakutia, and even created its synthetic analogues.
This discovery suggests that porous polymers – not synthetics in its purest form.
So, at the time of detection and zhemchuzhnikovita stepanovita crystal structure of these materials was unknown, while Soviet scientists have identified only by their formula.
Stepanova and Zhemchuzhnikova veins are thin translucent crystals or glass-green substance found in the form of inclusions in the coal-bearing strata and the remaining sediment, rich natural acetic acid. Scientists note that it is a single deposit in the world of natural IOC, t. To. They are created only in the permafrost and in the presence of natural acetic acid present in the composition of sedimentary rocks.
Their composition and X-ray crystallography data prompted Guskisa Frishchisa and the idea that they are very similar to the so-called “metal organic frameworks” – complex polymeric materials which are identical in structure to the honeycomb, which have a very high porosity and strength. Synthetic polymers by people who possess high strength and are used to create filters that absorb carbon dioxide or hydrogen. It was found that the formation of skeletons derived from compounds of various metals ions in permafrost. It turned out that intended for industrial purposes “metal organic frameworks” (IOC) exist in nature. Due to its structure, these materials are able to accumulate substantial amounts of these gases, but scientists did not expect that the nature of significant scientific developments ahead. In the last century chemists discovered that the composition of minerals include sodium, iron, magnesium, aluminum, water and some organic acids. The ions present in the crystals do not allow the minerals to absorb carbon dioxide and hydrogen. Discoverers zhemchuzhnikovita stepanovita and were able to determine its composition, but could not determine its structure.
