CO2-Driven Hydraulic Fracturing Trajectories across a Preexisting Fracture

Geofluids, 2021
Defining the trajectory of hydraulic fractures crossing bedding planes and other fractures is a significant issue in determining the effectiveness of the stimulation. In this work, a damage evolution law is used to describe the initiation and propagation

Ab initio modeling of oxygen impurity atom incorporation into uranium mononitride surface and subsurface vacancies

, 2012
The incorporation of oxygen atoms has been simulated into either nitrogen or uranium vacancy at the UN(001) surface, sub-surface or central layers. For calculations on the corresponding slab models both the relativistic pseudopotentials and the method of

Electrochemistry of Uranium [PDF]

Nature, 1946
AN account of the polarographic reactions of the uranium ions has just been published1. During 1944, experiments on this subject were made at this Laboratory, the publication of which has been delayed by war conditions. In general, our results confirm those of Kolthoff and Harris.

Two-loop self-energy correction in H-like ions [PDF]

, 2001
A part of the two-loop self-energy correction, the so-called P term, is evaluated numerically for the 1s state to all orders in Z\alpha. Our calculation, combined with the previous investigation [S. Mallampalli and J. Sapirstein, Phys. Rev.

Photochemical Decatungstate‐Catalyzed Hydroacylation of Maleimides

European Journal of Organic Chemistry, EarlyView.
A photocatalytic protocol to access substituted succinimides via tetra‐n‐butylammonium decatungstate photocatalysis is reported. This direct radical‐driven hydroacylation of a variety of N‐substituted maleimides shows tolerance to various aldehydes (or alkanes), affording differentially substituted succinimides in high yields. Succinimides constitute a

Phosphate and fluoride removal options for Hanford high‐level waste sludge processing

Environmental Progress &Sustainable Energy, EarlyView.
Abstract High‐phosphate and high‐fluoride sludges represent some of the most challenging waste streams within the Hanford High‐Level Waste (HLW) inventory due to solubility constraints, impacts on glass loading, and corrosion risks during vitrification.

Crucible cast from beryllium oxide and refractory cement is impervious to flux and molten metal [PDF]

, 1966
Crucible from a mixture of a beryllium oxide aggregate and hydraulic refractory cement, and coated with an impervious refractory oxide will not deteriorate in the presence of fused salt- molten metal mixtures such as uranium- magnesium-zinc-halide salt ...
