Sorbent-Based Microextraction Combined with GC-MS: A Valuable Tool in Bioanalysis
ChemosensorsSample preparation is broadly recognized as the most critical, time-consuming, and error-prone step of a bioanalytical workflow. Over the years, the development of pretreatment methods aimed at the isolation and preconcentration of the target analytes ...

Plant, Cell &Environment, Volume 49, Issue 8, Page 5689-5702, August 2026.ABSTRACT The rhizosphere harbours critical plant‐herbivore interactions often mediated by small lipophilic molecules (SLMs). Despite the agricultural importance of many soil‐dwelling insects, surprisingly little is known about chemically mediated belowground crop‐pest interactions. Root and shoot herbivores can influence these interactions by modifying

Plant Biology, Volume 28, Issue 5, Page 1454-1466, August 2026.Banksia attenuata (Proteaceae) attracts nocturnal scarab beetles with an unusual floral scent—the beetles pollinate the flower as they feed on pollen and nectar and mate on the inflorescences. Abstract Pollination by beetles has evolved multiple times in flowering plants but with relatively few plant species adapted specifically to pollination by ...

ChemPhysChem, Volume 27, Issue 13, 14 July 2026.A simple strategy is proposed to convert food waste such as dry bread into highly porous carbons that can be used for catalysis and adsorption‐related applications. Namely, a fast ball milling of dry bread and a mild activation agent, followed by carbonization at 800°C, is used to obtain porous carbons with surface areas up to 2400 m2/g.
