Nuclear magnetic resonance, a technique in its early stages in the field of proton imaging, appears to be very promising. It is capable of yielding not only morphological information, but also dynamic and metabolic information.

Synthesis, characterization, sintering, and leaching of beta-TUPD/monazite radwaste matrices.

Inorganic chemistry

Clavier N, Dacheux N, Podor R.
PMID: 16390059
Inorg Chem. 2006 Jan 09;45(1):220-9. doi: 10.1021/ic051607p.

To study the simultaneous incorporation of both tri- and tetravalent actinides in phosphate ceramics, we prepared several beta-TUPD/monazite-based radwaste matrices through two different chemical routes (called dry and wet routes) involving the initial precipitation of crystallized precursors of each...

Determination of Uranium, Thorium, Plutonium, Americium, and Curium Ultratraces by Photon Electron Rejecting α Liquid Scintillation.

PMID: 21639361
Anal Chem. 1997 Jul 01;69(13):2275-82. doi: 10.1021/ac961209r.

The determination of activities of thorium, uranium, plutonium, americium, and curium at very low levels has been performed by a new α liquid scintillation system (PERALS, name registered to Ordela, Inc.). The limit of detection has been determined for...

Inorg Chem. 2007 Nov 26;46(24):10390-9. doi: 10.1021/ic701297v. Epub 2007 Nov 01.

Several compositions of Th2-x/2AnIVx/2(PO4)2(HPO4).H2O (An=U, Np, Pu) were prepared through hydrothermal precipitation from a mixture of nitric solutions containing cations and concentrated phosphoric acid. All the samples were fully characterized by X-ray diffraction, UV-vis, and infrared spectroscopies to check...

PMID: 23721462
Inorg Chem. 2013 Jun 17;52(12):6957-68. doi: 10.1021/ic400272s. Epub 2013 May 30.

Experiments on the solubility of intermediate members of the Th(1-x)U(x)SiO4 solid solution were carried out to determine the impact of Th-U substitutions on the thermodynamic properties of the solid solution and then allow extrapolation to the coffinite end member....

Synthetic Biology Applied to Carbon Conservative and Carbon Dioxide Recycling Pathways.

Frontiers in bioengineering and biotechnology

PMID: 31998710
Front Bioeng Biotechnol. 2020 Jan 10;7:446. doi: 10.3389/fbioe.2019.00446. eCollection 2019.

The global warming conjugated with our reliance to petrol derived processes and products have raised strong concern about the future of our planet, asking urgently to find sustainable substitute solutions to decrease this reliance and annihilate this climate change...

Formation of CeSiO.

Thorite, (ThSiO4) with a zircon type structure, is one of the most abundant natural sources of thorium on Earth. Generally, actinides are known to form nanoparticles in silicate medium, though no direct link between those colloids and the crystalline...

BACKGROUND: Electrophysiological (EP) properties have been studied mainly in the monocrotaline model of pulmonary arterial hypertension (PAH). Findings are confounded by major extrapulmonary toxicities, which preclude the ability to draw definitive conclusions regarding the role of PAH per se...
