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 ...

Reduction of the formaldehyde content in leathers treated with formaldehyde resins by means of plant polyphenols [PDF]
Formaldehyde has applications in many industrial processes, including synthesis of resins and syntans to be used in the retanning process of leather. When resins are employed, they can hydrolyse, releasing formaldehyde.

Transition of plant resins from the biosphere to the lithosphere [PDF]
In the article the authors consider in detail the process of transition of plant resins from the biosphere to the lithosphere, characterize the conditions and paleogeographic situation of such transition, the formation of deposits of resin minerals and ...

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.

“Green” resole phenolic resins for laminating applications were synthesized, and their properties and thermal stability were determined. The plant-based cardanol and condensed tannin were used as the partial substitutes of up to 40% of the phenol in the ...

Development of Green Resin Using Solid Waste Protein Soybean Curd “Tofu” Production [PDF]
One of the most concerns associated with many commercially available composites is that they used of non-degradable resins and fibers that primarily made using non-degradable, petroleum-based chemicals as feed stock. These conditions will

Experimental maturation of pine resin in sediment to investigate the formation of synthetic copal and amber [PDF]
Experimentally simulating fossil resin formation would improve our understanding of copal/amber and could simulate the diagenesis of resin inclusions. Resin from living Pinus underwent sediment-encased maturation under various temperature and pressure ...

Plant Resins---Chemistry, Evolution Ecology and Ethnobotany [PDF]
Plant resins are often something ornamental horticulturists either ignore or endure-particularly when they clog up pruners. This book gives a different view-a rhyme and reason as to why plants produce resins and how generations of people have used resins for economic or personal benefit.

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 ...
