Impact of plant fiber reinforcement on mechanical properties of PMMA denture base resin: a systematic review [PDF]

open access: yesBiomaterial Investigations in Dentistry
Introduction: To improve the clinical outcomes and long-term durability of polymethyl methacrylate (PMMA) denture-based resins, they have undergone several developments and changes in their chemical composition to enhance their mechanical properties ...

Adsorption of plant phenols by polystyrene resins

open access: yesActa Societatis Botanicorum Poloniae, 2014
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.

Transition of plant resins from the biosphere to the lithosphere [PDF]

open access: yesGeo&Bio, 2020
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 ...

Plant Resins-Chemistry, Evolution Ecology and Ethnobotany [PDF]

open access: yesHortScience, 2005
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]

open access: yesFossil Record, 2021
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]

open access: yesPLoS ONE, 2013
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]

open access: yesPeerJ, 2015
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

Plant Sources Responsible for the Chemical Composition and Main Bioactive Properties of Poplar-Type Propolis

open access: yesPlants, 2020
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

open access: yesChemical Engineering Journal Advances, 2023
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 ...
