Multi‐Elemental Analysis for Geographical Tracing of Chickpeas Produced in Nearby Locations Around a Protected Geographical Indication

Plant, Cell &Environment, EarlyView.
ABSTRACT The multi‐elemental profile has repeatedly been proposed as a reliable indicator of the geographical origin of plant‐derived foods, as mineral composition accurately reflects the local soil geochemistry and environmental factors. However, this approach may fail in distinguishing specimens from nearby locations, which are expected to be exposed

Slab‐Mantle Interaction During Subduction Initiation: Constraints From Trace Element and Sr‐Nd‐Pb Isotope Systematics of Boninite and Other Magmas and Metamorphic Sole in the Oman Ophiolite

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Late Cretaceous Oman ophiolite includes a series of volcanic rocks generated during the transition from spreading ridge to protoarc associated with subduction initiation. We analyzed major and trace elements and Sr, Nd, and Pb isotope compositions of lavas and dikes of the protoarc stage, especially boninites. We also analyzed amphibolites

Improved Copper‐Zinc Based Catalysts for the Partial Dehydrogenation of Dicyclohexylmethanol

ChemCatChem, Volume 18, Issue 2, 28 January 2026.
Cu/ZnO/ZrO2 catalysts were synthesized by continuous co‐precipitation with subsequent batch suspension ageing. By analytical characterization and experimental testing in the partial dehydrogenation of dicyclohexylmethanol as a model reaction, structure‐activity correlations were derived.

Temperature effects on vanadium speciation and adsorption to biochar alone and biochar–metal oxide nanoparticle composites

Journal of Environmental Quality, Volume 55, Issue 1, January/February 2026.
Abstract Vanadium (V) is a potentially toxic metal widely distributed in the environment. This study investigates temperature effects on V adsorption and speciation in biochar (BC) and BC–metal oxide composites under conditions relevant to contaminated soils in temperate climates.
