Adsorption of plant phenols by polystyrene resins
Adsorption of nine plant phenols by nine polystyrene ion-exchange resins was investigated in an experimental model system. The phenols were adsorbed by Amberlite CG-120 more efficiently than any other acidically charged resins tested in this study.

Experimental induction of resins as a tool to understand variability in ambers [PDF]
Amber is chiefly known as a preservational medium of biological inclusions, but it is itself a chemofossil, comprised of fossilised plant resin. The chemistry of today's resins has been long investigated as a means of understanding the botanical sources ...

Metabolomics reveals the origins of antimicrobial plant resins collected by honey bees. [PDF]
The deposition of antimicrobial plant resins in honey bee, Apis mellifera, nests has important physiological benefits. Resin foraging is difficult to approach experimentally because resin composition is highly variable among and between plant families ...

Species-level determination of closely related araucarian resins using FTIR spectroscopy and its implications for the provenance of New Zealand amber [PDF]
Some higher plants, both angiosperms and gymnosperms, can produce resins and some of these resins can polymerize and fossilize to form ambers. Various physical and chemical techniques have been used to identify and profile different plant resins and have

Propolis is a resinous mixture, made by the honeybees from substances collected from tree or other plant buds, plant exudates, or resins found in the stem, branches, or leaves of different plants.

Recent advances in Fenton-like treatment of radioactive ion exchange resins
Ion exchange resins (IERs) are widely used to remove radioactive contaminants from various commercial nuclear power plant systems. After the completion of their useful life cycle, IERs are removed from the nuclear facility and are known as spent resins ...

Tree resin composition, collection behavior and selective filters shape chemical profiles of tropical bees (Apidae: Meliponini). [PDF]
The diversity of species is striking, but can be far exceeded by the chemical diversity of compounds collected, produced or used by them. Here, we relate the specificity of plant-consumer interactions to chemical diversity applying a comparative network ...

Stingless bees as collectors of resin from Bertholletia excelsa Bonpland (Lecythidaceae)
Stingless bees build their nests using, in general, clay, wax and resins; in addition, these bees also use resins for defense against natural enemies and as an antimicrobial agent.
