Molecular Architecture and Single‐Molecule Magnet behavior Control by Playing with Lanthanide Ionic Radii and Bulkiness Ancillary Ligands

Chemistry – An Asian Journal, Volume 20, Issue 10, May 15, 2025.
A library of polynuclear complexes involving the ditopic [4’‐(4’’’‐pyridyl‐N‐oxide)‐1,2’:6’1’’‐bis‐(pyrazolyl)pyridine] ligand was designed from the Ln(β‐diketonate)3(H2O)n building blocks. Both ionic radii size of the lanthanide and the bulkiness of the β‐diketonate allowed the control of the final molecular architectures while the second factor ...

Chiral N‐Alkylfluorenyl‐Substituted N‐Heterocyclic Carbenes in the Gold(I)‐Catalyzed Enantioselective Cycloisomerization of 1,6‐Enynes

Chemistry – A European Journal, Volume 31, Issue 19, April 1, 2025.
Four chiral [AuCl(A*Flu‐NHC)] complexes (A*Flu‐NHC for 9‐alkyl‐9‐fluorenyl N‐substituted N‐heterocyclic carbene) have been prepared in only four steps using commercially available enantiopure styrene oxide as chiral source. Their use as pre‐catalysts in the enantioselective cycloisomerization of 1,6‐enynes gave up to 72 % ee. A remarkable hydrogen bond

Improved understanding of soil water content at field capacity and estimates from pedotransfer functions

Irrigation and Drainage, Volume 74, Issue 2, Page 516-528, April 2025.
Abstract The soil water content at field capacity, θFC, is a fundamental variable for irrigation and agriculture. This study determines the optimal tension (−33 or −10 kPa) of deriving θFC which best matches the in situ field measurements following the Veihmeyer procedure.

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) relating to an analysis of the health risks associated with exposure to caterpillars with stinging hairs and the development of management recommendations

Food Risk Assess Europe, Volume 3, Issue 2, April 2025.
Abstract Several species of Lepidoptera with caterpillars bearing urticating hairs are increasing their range in metropolitan France from year to year, such as the pine processionary (Thaumetopoea pityocampa Denis et Schiffermüller 1775) whose presence was historically limited to the south of France, and which is gradually being observed in the north ...

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) on the assessment of the impact of fox population dynamics on public health

Food Risk Assess Europe, Volume 3, Issue 2, April 2025.
ABSTRACT The Red Fox (Vulpes vulpes) can be hunted as a game species. It may also be listed as a “species likely to cause damage” (ESOD – the acronym in French), for public health reasons among others. Conversely, benefits linked to the presence of foxes are also put forward, such as the predation of rodents carrying zoonotic agents.
