Eleventh Scientific Session “Young Scientists in the World of Polymers”

The eleventh scientific session “Young Scientists in the World of Polymers”, dedicated to the 30th anniversary of the Institute of Polymers – BAS, was held on 10.09.2020. For the first time the forum was held in the open, in front of the building of IP-BAS, due to the imposed emergency safety measures in connection with the epidemic situation. The session is organized every year in June. Despite the three-month delay, 29 young scientists took part presenting a total of 27 poster messages. Most of the participants were students in the Student Internships-Phase 2 program as well as young scientists from institutes of BAS (IOCCPC, IPC, IGIC, IEES, etc.) and from various Universities (FCP-SU, UCTM, FP-MU and more).

New materials for orthopedic implants are being developed at BAS

Laser-induced micro-foam of chitosan as a tissue-implant interface for application in tissue engineering. Laser processing of biocompatible polymers and ceramics for use in surgical interventions will be performed by scientists from the Institute of Electronics of BAS. The goal is to create antibacterial surfaces that will help patients recover faster after surgery. Laser-treated implant materials will accelerate cell development and postoperative wound healing. A cell attached to a layer of collagen that has been laser treated. The research is part of a project under the Marie Skłodowska-Curie Program, Innovative Training Networks. Scientists from 18 organizations across Europe are joining a network to create materials with antibacterial properties that are suitable for use on orthopedic implant surfaces. New coatings will be applied [...]

Scientists have taken rare images of the northern subspecies of reed cat

Camera traps captured rare footage showing Felis chaus chaus, the northern subspecies of the reed cat (or swamp cat) in the Korchay and Turyan-chay reserves (northern Azerbaijan). The cameras were installed as part of a joint study by the Institute of Zoology at the Azerbaijan National Academy of Sciences, WWF-Azerbaijan and the National Museum of Natural History-BAS. The study, which began in 2018, involved three Bulgarian scientists and one Azerbaijani scientist. The condition of rare and endangered predators in the Transcaucasia is being studied and also includes the leopard and the striped hyena. The reed cat is an Asian species that weighs up to 16 kg. It inhabits mainly wetlands overgrown with dense vegetation. Northern Azerbaijan is one of the northernmost parts of the range [...]
