Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Uranium–nitride chemistry: uranium–uranium electronic communication mediated by nitride bridges
Sequential reduction of a uranium-azide through all the nitride steps is revealed. Experimentally determined U–U coupling in the diuranium(iv)–dinitride is shown byab initiocalculations to stem from the nitride bridges, not U–U bonding.

Performance improvement of gamma ray spectrum logging tool based on LaBr3(Ce) scintillation crystals
BackgroundThe main ore-bearing rock of the Husab Uranium Mine in Namibia, southern Africa, is white granite, and the radioactive element thorium content in the ore is high, which has a greater impact on the γ ray logging results.PurposeThis study aims to

Functionalization of chitosan with 3,4-dihydroxybenzoic acid for the adsorption/collection of uranium in water samples and its determination by inductively coupled plasma-mass spectrometry [PDF]
A chitosan resin derivatized with 3,4-dihydroxybenzoic acid moiety (CCTS-DHBA resin) was newly synthesized for the collection/concentration of trace uranium by using cross-linked chitosan (CCTS) as base material, and the adsorption behavior of uranium as

About chemical form and binding energy of 14C in irradiated graphite of uranium-graphite nuclear reactors [PDF]
Issues associated with handling irradiated graphite of uranium-graphite nuclear reactors are examined. It is demonstrated that selection of approaches, methods and means for handling irradiated graphite are determined by the form of occurrence and ...
