Gallium selenide, a 2D semiconductor, loses electrical conductivity in air due to oxidation, hindering its application in nanoelectronic devices. Encapsulating GaSe in vacuum-manufactured devices with protective layers can maintain its optoelectronic properties.
A new study reveals that subsea permafrost in the East Siberian Arctic Shelf (ESAS) degrades at a rate of 18 cm/year, exceeding previous estimates. This suggests that massive methane emissions into the atmosphere may occur due to the destruction of hydrates, contradicting IPCC climate model predictions.
Researchers from Tomsk Polytechnic University have developed a technology to obtain liquid fuel from coal wastes for thermal power stations, reducing anthropogenic emissions and disposing of waste efficiently. The new fuel composition shows lower sulfur and nitrogen oxide emissions when burned compared to traditional coals.
Scientists at Tomsk Polytechnic University have developed a radiopharmaceutical for advanced cancer identification, using the technetium-99 isotope. The medication targets cancer receptors and can accurately determine tumor size and location.
Scientists at Tomsk Polytechnic University create protective coatings for zirconium fuel rods to prevent explosions in nuclear reactors. The titanium nitride-based coatings can reduce hydrogen penetration, extending the life of fuel rods and protecting reactor safety.
Scientists at Tomsk Polytechnic University have developed magnetic stem cells that can target cancer cells with precision and deliver medication directly to the tumor site. The technology uses patient's own magnet-controlled cells, which are not rejected by the immune system and cause less harm.
A new surveillance camera algorithm can process high-resolution 4K videos in real-time, detecting faces, genders, and approximate ages. The algorithm works 10 times faster than existing ones, enabling automatic monitoring and emergency situation identification without operator attention.
Tomsk Polytechnic University scientists create composite coating based on diamond and cubic boron nitride to improve durability and protect against high temperatures. The coating integrates the properties of diamond and nitride coatings, making it applicable to most metals.
