Machining of Uranium and Uranium Alloys [PDF]
, 1989 Abstract This article focuses on the basic metallurgy and machining parameters of classes of depleted and enriched uranium alloys. It provides information on the health precautions applicable to the machining of depleted uranium alloys. The article also discusses tool wear and the types of tools used in uranium alloy machining.

The End of Cheap Uranium [PDF]
, 2011 Historic data from many countries demonstrate that on average no more than 50-70% of the uranium in a deposit could be mined. An analysis of more recent data from Canada and Australia leads to a mining model with an average deposit extraction lifetime of

A molecular dynamics study of the thermal properties of thorium oxide [PDF]
, 2012 There is growing interest in the exploitation of the thorium nuclear fuel cycle as an alternative to that of uranium. As part of a wider study of the suitability of thorium dioxide (thoria) as a nuclear fuel, we have used molecular dynamics to ...

Establishment of rat model for aspiration pneumonia and potential mechanisms
Animal Models and Experimental Medicine, EarlyView.Aspiration pneumonia was induced in Sprague Dawley rats by intratracheal instillation of hydrochloric acid (HCl, 1.5 μL/g.wt, pH = 1) followed by lipopolysaccharide (LPS, 20 μg/g.wt) after 1 h. The model reproduced hallmark features of acute lung injury, including histological lung damage, microvascular dysfunction, inflammation, hypoxemia, and ...

Titanium‐Mediated Rearrangement of Bis(alkynyl)boranes: B─C Activation versus C─H Activation
Angewandte Chemie International Edition, EarlyView.Bis(alkynyl)boranes bearing different B‐substituents reacted with Cp*2Ti(Me3SiCCSiMe3), leading to the formation of B─C activation products (top right) and C─H activation products (bottom right), respectively. Abstract Reactions between Rosenthal's titanocene (Cp2Ti) and decamethyltitanocene (Cp*2Ti) synthons with various bis(alkynyl)boranes were ...

Promoting Alkane Binding: Crystallization of a Cationic Manganese(I)‐Pentane σ‐Complex from Solution
Angewandte Chemie International Edition, EarlyView.Oxidation of Mn₂(CO)₁₀ under pseudo gas‐phase conditions generates the weakly coordinated 16 valence electron complex [Mn(CO)₅]⁺, which binds n‐pentane as the strongest ligand available in this system. Three isomers were characterized by low‐temperature NMR and X‐ray crystallography.
