18F‐Radiopharmaceutical Diversification Enabled by Deaminative Cross‐Electrophile Couplings

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
A general Ni‐mediated (C)sp2–(C)sp3 cross‐coupling expedites access to 18F‐radiopharmaceuticals, essential for positron emission tomography imaging and drug discovery. This late‐stage diversification approach was implemented across three user‐friendly automated protocols affording 18F‐radiotracers in sufficient quantities for imaging.

Yeast‐Based Biotechnology for Civilian Security

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Yeasts constitute robust and versatile eukaryotic platforms for biotechnological applications relevant to civilian security. Both native and genetically engineered yeast systems enable sensitive detection of chemical and biological hazards, effective removal of metals and organic pollutants, and detoxification of mycotoxins.

Ecological, Functional, and Phylogenetic Determinants of Cyanobacterial Biomineralisation

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Cyanobacteria contribute to the global carbon cycle by biomineralising CO2 into solid carbonates. Unlike photosynthesis, biomineralisation is a less‐understood, multifaceted and adaptive metabolic process with significant global impact. It involves cell wall structures, genetic factors, and metabolic pathways that enable mineral formation and help ...

Potential of Soils Natural Sorbents for Environmental Decontamination From 137Cs

open access: yesLand Degradation &Development, Volume 37, Issue 2, Page 779-789, 30 January 2026.
ABSTRACT This study addresses the existing research gap concerning the lack of integrated data on the role of in situ soil components in the long‐term fixation of 137Cs under natural, protected, and non‐agricultural conditions. The contamination of ecosystems by radioactive isotopes, particularly 137Cs, represents a considerable environmental hazard ...

DETERMINATION OF EXTERNAL IRRADIATION FROM SOURCES WITH COMPLEX GEOMETRY CONTAINING RADIOACTIVE WASTE

open access: yesEast European Journal of Physics, 2016
A combined technique using both Monte-Carlo and quasi-analytic method has been developed for calculation of irradiation from complex objects containing radioactive waste. Monte Carlo method is used to calculate spectral, angular and spatial distributions

Isothermal Thermoluminescence Dating of Coral Reef Calcite: Implications for Sea‐Level Change

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Reconstructing past sea‐level changes is critical in Quaternary science. On remote oceanic reefs, aragonite‐to‐calcite alteration occurs during subaerial exposure, directly recording the timing of sea‐level fall. U–Th dating of coral calcite is challenging due to open‐system issues.
