Zirconium-methacrylate oxoclusters as new hybrid materials for the modification of epoxy systems
(Springer, 2015-04-01)
Oxozirconium clusters bearing methacrylate moiety (ZrMe) were synthesized by sol-gel process and used in epoxy networks to develop epoxy-based nanocomposites with potential application as encapsulant for light-emitting ...
Epoxy networks modified by multifunctional polyhedral oligomeric silsesquioxanes (POSS) containing amine groups
(Springer, 2008-07)
The hydrolytic condensation of a precursor synthesized by the reaction of equimolar amounts of (3-aminopropyl)triethoxysilane and phenylglycidylether led to a distribution of polyhedral oligomeric silsesquioxanes (POSS) ...
Predicting bioaccessibility of contaminants of emerging concern in marine sediments using chemical methods
(2018-04-01)
Purpose: A comparison was made between three chemical methods to predict bioaccessibility of triclosan (TCS), bisphenol A (BPA), and 17α-ethynylestradiol (EE2) in marine sediments, involving an exchangeable (E) value, ...
Durability of adhesives based on different epoxy/aliphatic amine networks
(Elsevier B.V., 2011-06-01)
The mechanical and adhesives properties of epoxy formulations based on diglycidyl ether of bisphenol A cured with various aliphatic amines were evaluated in the glass state. Impact tests were used to determine the impact ...
Efficiency of Different Chain-linking Agents in the Synthesis of Long-chain Branched Polypropylene. Molecular, Thermal and Rheological Characterization
(Taylor, 2017-09)
Long-chain branched polypropylenes were synthesized from a maleic anhydride grafted polypropylene (PPg). Different levels of branching were generated by reactive processing using four chain-linking agents: glycerol, ...
Durability of adhesives based on different epoxy/aliphatic amine networks
(Elsevier B.V., 2011-06-01)
The mechanical and adhesives properties of epoxy formulations based on diglycidyl ether of bisphenol A cured with various aliphatic amines were evaluated in the glass state. Impact tests were used to determine the impact ...
Toxicity of three emerging contaminants to non-target marine organisms
(2019-06-01)
Coastal areas are continually impacted by anthropic activities because they shelter large urban conglomerates. Urban effluents directly or indirectly end up reaching the marine environment, releasing a large number of ...
Stress analysis of an upper central incisor restored with different posts
(Blackwell Publishing, 2003-09-01)
The effect of different anatomic shapes and materials of posts in the stress distribution on an endodontically treated incisor was evaluated in this work. This study compared three post shapes (tapered, cylindrical and ...
Extração em fase sólida magnética de bisfenol A utilizando híbrido CoFe2O4/MON/GrafenoMagnetic solid phase extraction of bisphenol A using hybrid CoFe2O4/NOM/Graphene
(Pós-Graduação em QuímicaUniversidade Federal de Sergipe, 2021)
Optical storage in azobenzene-containing epoxy polymers processed as Langmuir Blodgett films
(ElsevierLausanne, 2013)
In this study, azocopolymers containing different main-chain segments have been synthesized with diglycidyl ether of bisphenol A (DGEBA, DER 332, n=0.03) and the azochromophore Disperse Orange 3 (DO3) cured with twomonoamines, ...
