UV aged epoxy coatings ̶ Ecotoxicological effects and released compounds

open access: yesWater Research X, 2021
Organic coatings can guarantee long-term protection of steel structures due to causing a physical barrier against water and oxygen. Because of their mechanical properties and resistances to heat and chemicals, epoxy resin-based coatings are widely used ...

Mechanically robust, hydrothermal aging resistant, imine-containing epoxy thermoset for recyclable carbon fiber reinforced composites

open access: yesMaterials & Design, 2022
Imine compounds have been proved to possess great potential in the design and preparation of sustainable epoxy thermosets. However, it is still a great challenge to develop imine-containing hardener with definite structure due to the randomness of ...

Fatty Acid Methyl Esters as Biosolvents of Epoxy Resins: A Physicochemical Study [PDF]

open access: yes, 2007
The C8 to C18 fatty acid methyl esters (FAME) have been compared as solvents for two epoxy resin pre-polymers, bisphenol A diglycidyl ether (DGEBA) and triglycidyl paminophenol ether (TGPA).

Naturally occurring epoxy acids: i. detection and evaluation of epoxy fatty acids by paper, thin-layer, and gas-liquid chromatography*†

open access: yesJournal of Lipid Research, 1961
Chromatographic procedures for the detection and evaluation of oxygenated fatty acids are described. Emphasis has been placed on epoxy acids, but these methods promise to be of great value in studies of all classes of oxygenated acids.

Epoxy Coenzyme A Thioester Pathways for Degradation of Aromatic Compounds [PDF]

open access: yesApplied and Environmental Microbiology, 2012
ABSTRACT Aromatic compounds (biogenic and anthropogenic) are abundant in the biosphere. Some of them are well-known environmental pollutants. Although the aromatic nucleus is relatively recalcitrant, microorganisms have developed various catabolic routes that enable complete biodegradation of aromatic compounds.

Mechanically relevant chemical shrinkage of epoxy molding compounds

open access: yes, 2022
6 S.One of the most prominent failure modes in microelectronics devices is the delamination of epoxy materials (adhesives, molding compounds). The thermal mismatch at the interface between materials leads to stresses that build up during processing steps

Two New Oxodolastane Diterpenes from the Jamaican Macroalga Canistrocarpus cervicornis

open access: yesMarine Drugs, 2017
The chemical investigation of the organic extract of Canistrocarpus cervicornis, collected at Drunken Man’s Cay at Port Royal, Jamaica, has led to the isolation of two new dolastane diterpenes 4R-acetoxy-8S,9S-epoxy-14S-hydroxy-7-oxodolastane (1) and 4R ...
