Thoracic aortic microcalcification activity in combined positron emission tomography and magnetic resonance imaging
ConclusionAscending aortic microcalcification analysis in PET-MRI is feasible with comparable findings to PET-CT. RadialVIBE-2 tissue attenuation correction correlates best with the reference standard of PET-CT and is less susceptible to artefact. There remain challenges in segmenting tissue types in PET-MRI reconstructions, and improved attenuation correction methods are required.

Predicting Lewis Acidity: Machine-Learning the Fluoride Ion Affinity of p-Block-Atom-based Molecules
Angew Chem Int Ed Engl. 2024 Mar 7:e202401084. doi: 10.1002/anie.202401084. Online ahead of print.ABSTRACT"How strong is this Lewis acid?" is a question researchers often approach by calculating its fluoride ion affinity (FIA) with quantum chemistry. Here, we present FIA49k, an extensive FIA dataset with 48,986 data points calculated at the RI-DSD-BLYP-D3(BJ)/def2-QZVPP//PBEh-3c level of theory, including 13 different p-block atoms as the fluoride accepting site. The vast amount of data allowed for hitherto unmatched correlations with other Lewis acidity descriptors, serving the qualitative understanding of Lewis acidity. ...

Humic acid-nanoceria composite as a sustainable adsorbent for simultaneous removal of uranium(VI), chromium(VI), and fluoride ions from aqueous solutions
Environ Sci Pollut Res Int. 2024 Mar 6. doi: 10.1007/s11356-024-32730-2. Online ahead of print.ABSTRACTIn this article, the multifunctional behavior of novel, efficient, and cost-effective humic acid-coated nanoceria (HA@CeO2 NPs) was utilized for the sorptive removal of U(VI), Cr(VI), and F- ions at different conditions. The production cost of HA@CeO2 was $19.28/kg and was well characterized by DLS, FESEM, HRTEM, FTIR, XRD, XPS, and TGA. Batch adsorption study for U(VI) (at pH ~ 8), Cr(VI) (at pH ~ 1), and F- (at pH ~ 2) revealed that the maximum percentage of sorption was > 80% for all the cases. From the contact time...
