THE SYNERGETIC OF FUEL ELEMENT

PROBLEMS OF ATOMIC SCIENCE AND TECHNOLOGY. SERIES: NUCLEAR AND REACTOR CONSTANTS, 2019
The fuel element is the complex system consisting of fuel, a sublayer, a cladding, protective coatings on a surface of a cladding and contacting to the cooler and material of a contour in general. The synergetic (self-coherence) of interaction of elements of this system has to be provided both concerning high heat conductivity of fuel element, and ...

From Single Atoms to Nanoparticles: Pathways Toward Efficient and Durable Pt/TiO2 Photocatalysts

Advanced Functional Materials, EarlyView.
Platinum single atoms on TiO2 nanosheets evolve into clusters and nanoparticles under ethanol photoreforming and thermal treatments. By controlling deposition and post‐treatments, particle size and location on specific facets are modulated. The study reveals how stability pathways determine efficiency, guiding the design of more durable photocatalysts.
