The synthesis and reactivity of uranium compounds supported by the tris-tert-butoxysiloxide ligand is surveyed. The multiple binding modes of the tert-butoxysiloxide ligand have proven very well suited to stabilize highly reactive homo- and heteropolymetal ...

Uranium nitride complexes are of high interest because of their ability to effect dinitrogen reduction and functionalization and to promote magnetic communication, but studies of their properties and reactivity remain rare. Here we have prepared in 73% yie ...

H2-fuelled microbial metabolism in Opalinus Clay

Rizlan Bernier-Latmani, Luca Loreggian, Niels Burzan, Aislinn Ann Boylan, Carla Perez Mon

In Switzerland, the Opalinus Clay formation is considered the most likely host rock for a deep geological repository for nuclear waste. In deep geological repositories, H2 is expected to be the most abundant gas formed from the degradation of waste and fro ...

Dissimilarities in polyphosphate accumulation between Shewanella loihica and the model bacterium Shewanella oneidensis

Julien Maillard

Polyphosphate plays an important role in the physiological adaptation of bacteria during growth and development, as well as in their response to nutritional and environmental stresses. Moreover, polyphosphate accumulation is of environmental relevance and ...

A large fraction (47%) of the world's uranium is mined by a technique called “In Situ Recovery” (ISR). This mining technique involves the injection of a leaching fluid (acidic or alkaline) into a uranium-bearing aquifer and the pumping of the resulting sol ...

, ,

The salt-elimination reaction of the complex [Na2U(bis-salophen)] with metal halides provides an entry to the synthesis of well-defined homobimetallic uranium–uranium and rare heterobimetallic uranium–cobalt and uranium–nickel complexes supported by a redo ...

Nitrogen reduction and functionalization by a multimetallic uranium nitride complex

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Lucile Sylvie Danielle Chatelain, Marta Falcone

Molecular nitrogen (N-2) is cheap and widely available, but its unreactive nature is a challenge when attempting to functionalize it under mild conditions with other widely available substrates (such as carbon monoxide, CO) to produce value-added compounds ...

Biogenic non-crystalline U(IV) revealed as major component in uranium ore deposits

Rizlan Bernier-Latmani

Historically, it is believed that crystalline uraninite, produced via the abiotic reduction of hexavalent uranium (U-(VI)) is the dominant reduced U species formed in low-temperature uranium roll-front ore deposits. Here we show that non-crystalline U-(IV) ...

Biostimulation as a remediation strategy post uranium acidic in situ recovery

Rizlan Bernier-Latmani, Pierre Rossi, Thomas Coral, Brian Carl Reinsch

A large fraction (47%) of the world’s uranium is mined by a technique called “In Situ Recovery”. This mining technique involves the injection of a leaching fluid (acid or alkaline) into a uranium-bearing aquifer and the pumping of the resulting solution th ...

Facile CO Cleavage by a Multimetallic CsU2 Nitride Complex

Rosario Scopelliti, Marinella Mazzanti, Marta Falcone

Uranium nitrides are important materials with potential for application as fuels for nuclear power generation, and as highly active catalysts. Molecular nitride compounds could provide important insight into the nature of the uranium–nitride bond, but curr ...
