Bandgap Tunability in Sb-Alloyed BiVO4 Quaternary Oxides as Visible Light Absorbers for Solar Fuel Applications

One approach to reducing the bandgap is the utilization of ternary and quaternary oxides, which have been receiving increased attention as light absorbers that, critically, also supply the potential needed to drive multi-electron oxidn. reactions. In this ...

Long-term in-situ oxidation of biogenic uraninite in an alluvial aquifer: impact of dissolved oxygen and calcium

Rizlan Bernier-Latmani, Elena Suvorova Buffat, Harish Veeramani, Daniel Scott Alessi

Oxidative dissolution controls uranium release to (sub)oxic pore waters from biogenic uraninite produced by natural or engineered processes, such as bioremediation Laboratory studies show that uraninite dissolution is profoundly influenced by dissolved oxy ...

Experimental tests of an advanced proton-to-neutron converter at ISOLDE-CERN

The suppression of isobaric contaminations is of growing importance for many scientific programs using radioactive isotopes produced at isotope separation on-line (ISOL) facilities, such as ISOLDE-CERN. A solid tungsten proton-to-neutron converter has been ...

Tridentate Benzimidazole-Pyridine-Tetrazolates as Sensitizers of Europium Luminescence

Rosario Scopelliti, Jean-Claude Bünzli, Svetlana Eliseeva

We report on new anionic tridentate benzimidazole-pyridine-tetrazolate ligands that form neutral 3:1 complexes with trivalent lanthanides. The ligands are UV-absorbing chromophores that sensitize the red luminescence of europium with energy-transfer effici ...

A Uranium-Based UO2+-Mn2+ Single-Chain Magnet Assembled trough Cation-Cation Interactions

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

Single-chain magnets (SCMs) are materials composed of magnetically isolated one-dimensional (1D) units exhibiting slow relaxation of magnetization. The occurrence of SCM behavior requires the fulfillment of stringent conditions for exchange and anisotropy ...

Analysis of hardening limits of oxide dispersion strengthened steel

Amuthan Ramar

Oxide dispersion strengthened (ODS) ferritic/martensitic (F/M) steels are promising materials for high temperature applications. The hardening limits from room temperature to 1000 degrees C of one of such steel, ODS EUROFER97, together with the impact of t ...

Controlled Thermolysis of Uranium (Alkoxy) siloxy Complexes: A Route to Polymetallic Complexes of Low-Valent Uranium

Marinella Mazzanti

Decomposition into higher species: Intramolecular UIII-mediated homolytic C-O bond cleavage in UIII (alkoxy)siloxy complexes at low temperature and subsequent reduction with KC8 led to unprecedented polymetallic complexes containing siloxy, silanediolate, ...

Mobile uranium(IV)-bearing colloids in a mining-impacted wetland

Rizlan Bernier-Latmani, Manon Frutschi, Elena Suvorova Buffat, Yuheng Wang

Tetravalent uranium is commonly assumed to form insoluble species, resulting in the immobilization of uranium under reducing conditions. Here we present the first report of mobile U(IV)-bearing colloids in the environment, bringing into question this commo ...
