Nicotinamide and Sodium Butyrate Double the Pool of Treatment‐Exclusive Metabolites in the Endophytic Fungus Curvularia sp. G6‐32

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Epigenetic modulators nicotinamide and sodium butyrate reshape the chemical landscape of the endophytic fungus Curvularia sp. G6‐32. Combining the OSMAC strategy with UHPLC‐MS/MS metabolomics and molecular networking reveals a more than twofold rise in treatment‐exclusive metabolites, including diketopiperazines and potentially bioactive natural ...

Germylium Catalyzed Dehydrofluorination Reactions of Fluorinated Alkanes

Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
Dehydrofluorination reactions of fluorinated alkanes catalyzed by germylium ions are reported. Computational studies of the mechanism revealed an E2 type mechanism involving a germane as a base to facilitate olefin formation in competition with an SN2 mechanism for hydrodefluorination.

Precipitation Regulates Phenological Responses of Annual and Perennial Forbs to Warming and Degradation in an Alpine Meadow on the Qinghai–Xizang Plateau

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Warming and degradation had negligible multi‐year mean effects on annual plant phenology, but their impacts varied strongly with interannual precipitation and spring soil moisture. Degradation amplified warming‐induced advancement of leaf‐out and extended the total active period of the perennial Aster tataricus via microclimatic amplification and ...

Ligand Redox Noninnocence in Bis(phosphinimine) Diarylamido Pincer Complexes of Nickel

European Journal of Inorganic Chemistry, Volume 29, Issue 28, 1 October 2026.
The oxidative noninnocence of a bis(phosphinimine) ligand featuring a diarylamido backbone was investigated for several nickel complexes. Radical/charge delocalization across the aromatic backbone plays an important role in the stabilization of the diarylaminyl and putative diarylnitrenium complexes.

Optimising Sulphur Fertilisation in Ryegrass–White Clover Swards Reduces Leached Nitrate Nitrogen Losses, While Increasing Plant Yield and Nitrogen Off‐Take

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 5, Page 666-680, October 2026.
The inclusion of sulphur at two inorganic nitrogen rates (0 and 150 kg N ha−1) improves plant productivity in a ryegrass–white clover sward and reduces nitrate‐N loss to groundwater in a free‐draining sandy loam soil. ABSTRACT Background Reducing nitrogen (N) losses to water, lessening reliance on inorganic fertiliser and maintaining agricultural ...
