TPU chemists convert plastic bottle waste into insecticide sorbent

 E-Mail Scientists of Tomsk Polytechnic University proposed a method to create a sorbent for imidacloprid insecticide removal from water. The sorbent belongs to metal-organic frameworks, a class of non-conventional materials. The TPU chemists grew such a framework right on polyethylene terephthalate (PET) used to produce regular plastic bottles. The method is quite simple and allows converting used materials into a useful product. The research findings are published in Applied Materials Today academic journal (IF: 8,352; Q1). Metal-organic frameworks are substances with a three-dimensional structure, where clusters or metal ions are bridged by organic ligands. The result is a porous material with the properties of both metals and organic compounds.

Chronic stress? Zebrafish to the rescue

Credit: Natalia Arefieva/MIPT Press Office A team of researchers led by MIPT s Allan Kalueff has studied chronic stress in zebrafish and determined that the animal can serve as a valuable model species for research into the associated brain diseases, complementing research currently done on rodents. The paper was published in Scientific Reports. Translational model The zebrafish, also known as Danio rerio, is a freshwater fish from the minnow family. It got its name for the stripes on its body. Zebrafish are widely used as a translational model in genetics, molecular biology, embryology, pharmacology, and more recently in neurobiology. Their use as lab animals was pioneered in the 60s by U.S. biologist George Streisinger.

Russian universities and scientific organizations approve projects of three nanosatellites

Russian universities and scientific organizations approve projects of three nanosatellites A consortium of Russian universities and scientific organizations to create a constellation of nanosatellites for studying the Earth s ionosphere was set up in 2018 © Samara National Research University December 8. /TASS/. Members of an association of Russian universities and scientific organizations approved the projects of the first three nanosatellites of the future orbital consortium created within the consortium. The satellites will help in the study of the ionosphere, the development of the Arctic and Antarctic, the identification of sea vessels, the press service of the Samara National Research University said on Tuesday.
