Development of highly selective ligands for separations of actinides from lanthanides in the nuclear fuel cycle [PDF]

open access: yes, 2011
This account summarizes recent work by us and others on the development of ligands for the separation of actinides from lanthanides contained in nuclear waste streams in the context of a future European strategy for nuclear waste management. The current

Realistic species loss has little effect on local resource depletion and competitive pressure in a temperate wet meadow

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Realistic biodiversity loss in a species‐rich wet meadow had limited effects on community competitive ability. Phytometers revealed strong competition compared to competition‐free gaps, but similar pressure across richness levels (1–27 species). Resource depletion poorly explained responses, highlighting that dominance, seasonal dynamics and biotic ...

Synthesis of pincer-type extractants for selective extraction of palladium from PGMs: An improved liquid-liquid extraction approach to current refining processes

open access: yesScientific Reports, 2017
SCS pincer ligands 1–4 were synthesised, and their ability to extract Pd(II) from HCl and HNO3 media was studied. The Pd(II) extraction properties of 1–4 were compared with those of commercial extractants (DOS and LIX®84-I) in kerosene.

Molecular design of phenolic type extractants

open access: yesТонкие химические технологии, 2010
A method of optimization of new extractants' structure with the use of desirability function has been developed. The desirability function had been proposed before by Harrington for optimization of processes with several response functions.

Environmental aspects of soil phosphorus testing [PDF]

open access: yes, 2005
peer-reviewedSoil phosphorus testing in Ireland uses Morgan’s reagent from samples taken to 10 cm depth for agronomic recommendations. However, its suitability as an environmental indicator has been questioned in terms of sample depth and extraction ...
