Observations Concerning Rhizobium tropici Bacteroid Phosphorus Stress Response During Symbiosis With Phaseolus vulgaris. [PDF]
Environ Microbiol Rep14CO2 and 32PO4 labelling of bean was used with Rhizobium tropici mutants. An alkaline phosphatase mutant was not affected for bacteroid P acquisition, though bacteroid and nodule 14C‐carbon uptake was altered. The high‐affinity P transporter mutant was defective in nodule P acquisition and symbiotic performance. Plant image by Brgfx/Freepik.

Stable BF<sub>2</sub> Boracycles as Versatile Reagents for Selective Ortho C-H Functionalization. [PDF]
Angew Chem Int Ed EnglWe report a robust, metal‐free and scalable synthesis of stable BF2 boracycles via directed ortho CH borylation, delivering isolable, shelf‐stable reagents without chromatographic purification. These BF2 boracycles exhibit unique and tunable reactivity, enabling highly selective ipso‐functionalization across a broad range of transformations.

Proposed high-power beta cells from MgAlB14-type icosahedral-boron semiconductors
, 2019 Beta cells generate electric power as carrier-producing beta irradiation from incorporated radioisotopes bombard a series of p-n-junctions. However, radiation damage to the semiconductors commonly used in solar cells limits beta cells to extremely weak ...

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.

Water Science and Engineering, 2015 AbstractTo evaluate the effect of benthic algae on soluble reactive phosphorus (SRP) release from sediments in shallow lakes, experiments on SRP release with and without benthic algae in sediment cores and an experiment on SRP uptake by benthic algae were conducted using the radioisotope (32P) tracing method.

Net mineralizable soil phosphorus cannot be measured by non‐isotopic approaches
Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.Abstract While radioisotopic pool dilution is widely regarded as the most reliable method for estimating soil phosphorus mineralization (Pmin), high costs, low throughput, and safety requirements limit its use. We evaluated the potential of non‐radioisotopic approaches to estimating net Pmin by difference before and after aerobic incubation, analogous ...

Batteries &Supercaps, Volume 9, Issue 5, May 2026.Lithium‐ion batteries used in space applications are exposed to extreme conditions, including radiation, vacuum, wide temperature fluctuations, and long storage times, all of which accelerate degradation. This review article summarizes the main degradation mechanisms affecting battery performance in space environments, including capacity fade ...

Dreams and needs : the applications of isotopes to industry in Spain in the 1960s [PDF]
, 2009 The efforts to change the bleak image of the atom bomb galvanised the discourse on the peaceful applications of nuclear energy. This contributed to a utopian vision of nuclear energy, especially of the uses of radioactive isotopes in the immediate post ...

Upper Ocean Cycling of Iron South of the Polar Front: Biological Patterns and Processes
Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.Abstract Samples from the upper 300 m along the 52°S band, south of the Antarctic Polar Front in the Atlantic sector of the Southern Ocean, including a 3‐week monitoring of a persistent bloom, were analyzed to advance our understanding of iron cycling and supply to recurrent phytoplankton blooms.
