From 11 to 13 October chemists from 35 countries discussed the challenges posed by the transformation of the energy system. Attendees of the forum "Fundamental Concepts and Principles of Chemical Energy Conversion", 172 scientists from 35 countries, have discussed which materials and technologies for energy conversion are expected to be implemented in the future. Experts have presented approaches being taken in the fields of nanotechnology and surface chemistry or used in the development of new storage materials, such as for rechargeable batteries. The Bonn Humboldt Award Winners' Forum focused also on research being conducted on superconductors as well as on light-harvesting properties of materials used for solar cells.
The Republic of Moldova was represented by Prof. Vasile Tronciu (TUM), Dr. Eduard Monaico (TUM), Prof. Anatolie Sidorenco (ASM) and Dr. Vadim Sirkeli (Comrat University).
A new optical scattering and absorbing material created by an international group, including scientists from Germany, Moldova, Denmark, and Australia, consists of microscopic tetrapods made of aerogra
phite carbon, with these microtetrapods covered with a "fur" of much smaller nanotetrapods made of zinc oxide (ZnO) crystals.1 The material dem
onstrates photoabsorption in the UV and visible regions due to the wide bandgap of ZnO and its intrinsic defects, and photoabsorption in the IR due to the architecture of the ZnO nanostructures and their doping by carbon impurities. The tetrapod mixture can be attached to stretchable substrates if desired.
Ambasada Germaniei în Republica Moldova a transmis o donație de utilaj științific Centrului Național de Studiu și Testarea Materialelor din cadrul Universității Tehnice a Moldovei. Înmânarea oficială a echipamentului laser cu emisie infraroșie și a unui boxcar integrator, procurate în baza unui grant oferit de Fundația Alexander von Humboldt, a avut loc la 1 februarie 2017.
The automotive and aeronautic industries are looking for more lightweight materials to reduce the weight of the future cars and airplanes, and ultimately the fuel they consume and pollution they produce. Among the devices that contribute the mass of vehicles are an array of sensors. in a recent Nanotechnology article, researchers from the Institute of Microtechnologies in Bucharest, Romania, and the Academy of Sciences and Technical University in Chisinau, Republic of Moldova, report on flexible, ultra-lightweight pressure sensors based on graphene aerogel decorated by piezoelectric SnO2 or GaN nanocrystalline thin films.
Cercetătorii de la Institutul de Inginerie Electronică şi Nanotehnologii al Academiei de Ştiinţe a Moldovei, Centrul Naţional de Studiu şi Testare a Materialelor al Universităţii Tehnice a Moldovei şi Institutul de Microtehnologie din Bucureşti, sub conducerea academicianului Ion Tighineanu şi profesorului Mircea Dragoman, au elaborat senzori de presiune care cântăresc jumătate de miligram, fiind de circa 6-8 ori mai uşori decât fulgii de zăpadă.
Молдавские ученые совершили открытие в области нанотехнологий. Они разработали ультратонкие наномембраны. Рассмотреть их можно только при помощи специальных медицинских микроскопов, ведь толщина их составляет миллионную долю миллиметра. О том, где можно использовать это открытие, рассказывает корреспондент телеканала «МИР 24» Ксения Яниева.
