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]
, 2007 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

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

Uranium–nitride chemistry: uranium–uranium electronic communication mediated by nitride bridges
Dalton Transactions, 2022 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.
