Radium Speciation in Simulated Digestive Biofluids: Insights from Electrospray Ionization Mass Spectrometry and Thermodynamic Modeling

open access: yesAnalysis &Sensing, Volume 6, Issue 2, March 2026.
Electrospray ionization mass spectrometry (ESI‐MS) combined with thermodynamic modeling provides the first direct characterization of radium speciation in synthetic gastrointestinal biofluids. Free Ra2+ ions predominate with minimal protein binding and negligible EDTA complexation. Crown ethers enable effective Ra complexation.

Phosphorus‐Structured Gel Electrolytes Enable Dual Protection for Thermal Runaway‐Resistant Lithium Metal Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
The PD‐VI GPE synthesized via in situ γ‐ray polymerization facilitates formation of a dense F/P‐rich SEI layer, enabling stable Li deposition while suppressing interfacial side reactions. The phosphorus‐containing framework enhances separator thermal stability and effectively mitigates O2 release from cathodes, demonstrating improved safety under the ...

Organic Linker Hybridization Induced Tunable and Intense Ultra Violet Emission From Zeolitic Imidazolate Framework‐8

open access: yesChemistrySelect, Volume 11, Issue 12, 26 March 2026.
Linker‐exchanged and solvated ZIF‐8 exhibit tunable, intense emission across the UVB‐UVC‐UVA range, a result of altered charge transfer dynamics due to the incorporation of benzimidazole as the new linker and the guest‐host interactions between the confined N,N‐dimethylformamide and the ZIF‐8 framework.

Preclinical comparison of four [18F, natGa]rhPSMA-7 isomers: influence of the stereoconfiguration on pharmacokinetics

open access: yesEJNMMI Research, 2020
Introduction Radiohybrid (rh) ligands, a novel class of prostate-specific membrane antigen (PSMA)-targeted radiopharmaceuticals, can be labeled either with [18F]fluorine via isotopic exchange or with radiometals (such as [68Ga]Gallium, [177Lu]Lutetium ...

Thermodynamic and Thermophysical Properties of Early Lanthanide Fluorides: LaF3, CeF3, PrF3, NdF3, SmF3, EuF3, and GdF3

open access: yesChemistrySelect, Volume 11, Issue 9, 5 March 2026.
ABSTRACT Thermodynamic and thermo‐physical properties of fission products play a crucial role in the safe operation of a nuclear reactor. Since, in molten salt rectors (MSRs), lanthanide fluorides will be important fission products, isobaric molar heat capacities (cp) of trifluorides of the light lanthanides (LaF3, CeF3, PrF3, NdF3, SmF3, EuF3, and ...

How Well Do We Know VPDB—Part 2: Interlaboratory Assessment of Existing δ13CVPDB Reference Materials

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 4, 28 February 2026.
ABSTRACT Rationale In January 2024, the IAEA experts meeting endorsed both δ13C scales that are currently used within the scientific community: the Vienna Peedee belemnite (VPDB) δ13C scale defined by NBS 19 with a value of +1.95‰ exactly, and the VPDB‐LSVEC scale defined by NBS 19 and the lithium carbonate LSVEC with a value of −46.60‰ exactly ...

A2A Adenosine Receptor Agonists With Last‐Step Enzymatic 18F‐Labelling Potential (Fluorinase) for Positron Emission Tomography (PET)

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 5, 7 February 2026.
This study exploits the comparable binding tolerances between the fluorinase enzyme and the A2A adenosine receptor towards the development of novel C‐2 functionalised 5′‐fluorodeoxy‐adenosine (FDA)‐based agonists with enzymatic 18F‐labelling capability for positron emission tomography (PET).
