Synthesis of oxides and determination of uranium concentration in uranyl nitrate compounds using irradiation by double laser pulses
TLDR
In this paper, the surface of a porous solid containing micro amounts of uranyl nitrate hexahydrate using irradiation by two sequential pulses with pulse-to-pulse intervals in the range 4-12μs was studied.Abstract:
Spectroscopic studies of the surface of a porous solid containing micro amounts of uranyl nitrate hexahydrate using irradiation by two sequential pulses with pulse-to-pulse intervals in the range 4–12 μs have shown that laser chemical synthesis of uranium and uranium oxide nanoclusters within the interior of a porous solid is a promising technique, with the possibility at the same time of determining the uranium content with good sensitivity (~10–10 g).read more

Structural and electronic properties of UnOm (n=1-3,m=1-3n) clusters: A theoretical study using screened hybrid density functional theory
Yu Yang,Haitao Liu,Ping Zhang +2 more
TL;DR: This work is the first one on the screened hybrid density functional theory level studying the atomic and electronic properties of the actinide oxide clusters, and it is found that the formation of U-O-U bondings and isolated U-U bonds are energetically more stable than U- U bondings.

Designing oxidation catalysts
TL;DR: In this paper, a simplified approach is described for the design of oxidation catalysts, which is based on three components and for selective oxidation the approach involves identifying catalysts that do not catalyse the oxidation of the required product under the reaction conditions to be tested, activating the oxidant and activating the substrate.
