Scientists from TPU, Germany, and the United States have found a new way to functionalize a dielectric, otherwise known as ‘white graphene’, i.e. hexagonal boron nitride (hBN), without destroying it or changing its properties. Thanks to the new method, the researchers synthesized a ‘polymer nano carpet’ with strong covalent bond on the samples. Prof Raul…
Scientists Discovered Where Black Carbon Comes From in the Arctic in Winter and Summer
Scientists from seven countries, including Austria, the Netherlands and five key Arctic states (Russia, USA, Canada, Norway, and Sweden) – participants of the International Arctic Science Committee (IASC) published an article on the study of the so-called sources of black carbon emissions in the Arctic in the Science Advances. Black carbon (BC) aerosols are formed under…
Scientists Improve Resolution of Powerful Microscopes
Researchers from Tomsk Polytechnic University (Russia) and Bangor University (UK) have experimentally verified anomalous amplitude apodization for non-spherical particles for the first time. This phenomenon makes it possible to boost the magnifying power of microscopes and to more effectively record molecules and viruses. The study results were reported in Journal of Infrared, Millimeter, and Terahertz Waves.…
Graphene Goes on a Magic Nanocarpet Ride
Researchers from Tomsk Polytechnic University, together with their international colleagues, have discovered a method to modify the ultra-thin conductor of current and heat graphene without destroying it. Thanks to the novel method the researchers were able to synthesize on graphene samples of a well-structured polymer with a strong covalent bond, which they called “polymer carpets.”…
Gold Nanoanntennas Help in Creation of More Powerful Nanoelectronics
Applying Advanced Non-Stable Semiconductors in Nanoelectronics
A research group consisting of scientists from Tomsk Polytechnic University, Germany, and Venezuela proved vulnerability of a two-dimensional semiconductor gallium selenide in air. This discovery will allow manufacturing nanoelectronics based on gallium selenide, which has never been previously achieved by any research team in the world. The study was published in Semiconductor Science and Technology.…

Russia’s First 3D-Printed Satellite Preparing to Launch into Outer Space
The crew of the Russian segment of the International Space Station (ISS) checked the operation of the Tomsk-TPU-120 satellite on July 24. Satellite launch into outer space is scheduled on August 17, 2017. Tomsk-TPU-120 satellite is the first Russian satellite which was 3D-printed and the advanced materials were used. It refers to nano-satellites with the…
Coatings for Nuclear Fuel Preventing Explosions in Reactors
Physicists from Tomsk Polytechnic University are creating protective titanium nitride-based coatings for shells of fuel elements (fuel rods) of nuclear reactors. Such shells can significantly reduce hydrogenation of containers in which nuclear fuel is placed, extend their service life and protect reactor from explosion like at the Fukusima radiation disaster. “In reactors nuclear fuel is…
Magnetic Stem Cells for Gene Engineering
Scientists from the Tomsk Polytechnic University’s Laboratory of Novel Dosage are developing a technology to control mesenchymal stem cells of patients. The technology will allow treating cancer more effective. To fight cancer cells the scientists suggest using the patient’s own magnet controlled cells. Native body cells won’t be rejected by its immune system and can…
