Water‐Dispersible Ruthenium Nanocatalyst for Carbonyl Reduction With D2 or T2 in Aqueous Media

open access: yesAngewandte Chemie International Edition, EarlyView.
We report the synthesis and characterization of water‐dispersible ruthenium nanoparticles that catalyze the reductive deuteration and tritiation of carbonyl compounds in aqueous media, enabling efficient access to a broad range of isotopically labeled polar molecules, including cyclic peptides, antibody‐drug conjugate linkers, pegylated derivatives ...

Selected radioisotopes` concentrations in integrated reactor effluent water samples [PDF]

open access: yes, 1962
This document contains the results of weekly sampling of various isotope concentrations from effluent water at the 100 area at Hanford from July 1962 to February 1965. Compiled data in microcuries/milliliter are given.

Trade‐offs between soil biodiversity and agricultural expansion: Evidence from litter decomposition dynamics in Madagascar

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Home‐Field Advantage (HFA) theory—positing that litter decomposes faster at its site of origin—allows us to disentangle the respective influences of litter quality, soil biota composition, and microclimate on shifts in litter decomposition following land use conversion.

Stable BF2 Boracycles as Versatile Reagents for Selective Ortho C–H Functionalization

open access: yesAngewandte Chemie, Volume 138, Issue 8, 16 February 2026.
We 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.

Evaluation of Effects of Phosphorus Concentration on Microbial Population and Material Flux in Aquatic Microcosm Using Radioisotope Tracer

open access: yesJapanese Journal of Water Treatment Biology, 2003
In this study, effects of phosphorus concentration on aquatic microcosms were evaluated in terms of microbial population dynamics and the photosynthetic activity that is the starting point of the material flux. Microcosms that consist of algae Chlorella vulgaris, bacteria Pseudomonas putida and ciliate Cyclidium glaucoma were incubated using media that

Distinct Foliar Uptake Pathways for Phosphorus and Nano‐Hydroxyapatite in Potato Revealed By Synchrotron μCT and ³³P Imaging

open access: yesPlant, Cell &Environment, Volume 49, Issue 8, Page 5563-5579, August 2026.
ABSTRACT Potato (Solanum tuberosum L.) has a high phosphorus (P) requirement, yet its shallow root system and the strong P‐fixing capacity of many soils limit the effectiveness of soil fertilisation. Foliar application of nano‐hydroxyapatite particles (nHAPs) has emerged as a promising alternative P fertilisation practice.

Management effects on biological cycling of phosphorus in Southern Australia [PDF]

open access: yes, 2004
Biological cycling of phosphorus (P) in soils includes various processes: the release and mineralisation of P from plant residues, microbial immobilisation, re-mineralisation and turnover, mineralisation of soil organic P, and flush effects due to ...

Electrochemical Detection of Vanadium Using a Boron‐Doped Diamond Electrode as a Surrogate for Radioactive Heavy Metals

open access: yesElectroanalysis, Volume 38, Issue 7, July 2026.
A boron‐doped diamond (BDD) electrode‐based anodic stripping voltammetry (ASV) method was developed for the electrochemical detection of radioactive heavy metals in nitric acid media using vanadium as a nonradioactive surrogate for neptunium. Systematic optimization identified an O‐terminated BDD electrode operated at a deposition potential of −1.2 V ...
