Column separation of tetravalent cerium fission products from trivalent rare earth radio-isotopes

Mateusz Dembowski et al.

Summary: Rapid and efficient isolation of individual rare earth element (REE) radioisotopes from complex mixtures is crucial for various scientific applications. The current method involves a laborious two-step process, but an alternative approach using Ce(IV)/LN-resin based separation showed promising results. Despite lower decontamination factors, the simplicity and effectiveness of the LN-resin method make it a viable option for fission product analysis.

Exploring lanthanide separations using Eichrom's Ln Resin and low-pressure liquid chromatography

Jessica Ward et al.

Summary: This study systematically evaluated the analytical separations of lanthanide elements using Ln resin and low-pressure chromatography columns, showing that most elements can be baseline separated with careful selection of conditions. However, Nd, Pr, Pm, and Ce co-elute at low acid concentrations. A novel Ce3+/Ce4+ oxidation-reduction approach enables the isolation of Ce, but baseline separation of Nd, Pr, and Pm remains a challenge using the current methods.

Developing the 134Ce and 134La pair as companion positron emission tomography diagnostic isotopes for 225Ac and 227Th radiotherapeutics

Tyler A. Bailey et al.

Summary: The development of targeted alpha therapies can potentially revolutionize disease treatment by delivering destructive radiation to diseased cells while sparing healthy tissue. Despite challenges with incompatible isotopes, researchers successfully produced Ce-134 for PET imaging, demonstrating its potential as a candidate for imaging Ac-225 or Th-227. Rigorous control of the Ce-III/Ce-IV redox couple was crucial for success in these experiments.

Distribution Coefficients of the REEs, Sr, Y, Ba, Th, and U between α-HIBA and AG50W-X8 Resin

Haoyu Li et al.

Summary: This study presents experimental results on the distribution coefficients of REEs between alpha-HIBA and cation-exchange resin. The distribution coefficients decrease with increasing acid concentration; for REEs, a linear relationship is observed between K-d values and alpha-HIBA molarity.

Development of 148Gd analysis method using stable Gd

Grzegorz Olszewski et al.

Summary: The analytical method developed aims to analyze Gd-148 in environmental and bioassay samples using anion exchange resin, extraction chromatography, and cation exchange resin. Solid samples are dissolved using alkaline fusion and calcium oxalate co-precipitation, while liquid samples are preconcentrated. The total recovery of the method when tested with natural Gd (Gd-157) using ICP-QQQ-MS reached a maximum of 75%.

Bioactivity-guided separation of potential α-glycosidase inhibitor from clerodendranthus spicatus based on HSCCC coupled with molecular docking

Chunsheng Zhu et al.

Summary: The study successfully purified effective ingredients of Clerodendranthus Spicatus using high-speed counter-current chromatography. Among the identified compounds, 2-caffeoyl-L-tartaric acid and rosmarinic acid exhibited higher inhibitory activity against α-glucosidase, showing potential as promising hypoglycemic drugs. Through molecular docking, it was found that rosmarinc acid had the lowest affinity energy and was wrapped with 6 hydrogen bonds, indicating its likelihood as a hypoglycemic drug.
