In this study, polyester composites reinforced with pistachio shells powder (P.) an averagediameter (150 – 200 μm) different weight ratios (0.5%, 1%, 1.5%, 2%, and 2.5%) wereprepared to the resin. The Shore D hardness, thermal conductivity (K), glass transitiontemperature (Tg) of samples were examined. results showed that hardnessincreases increase reinforcement ratio its maximum value is (87.5...
Flame retardants, such as inorganic fillers or halogenated resins, are incorporated into composites either as additives or reactive materials. In order to improve processability and mechanical properties, as well as reduce smoke toxicity, a method is being developed to introduce highly effective, inexpensive flame retardant materials into thermoset resins. Superabsorbent polymers (SAP) can be l...
Intramolecular cycloadditions of photogenerated azaxylylenes: an experimental and theoretical study.
The mechanism of intramolecular cycloadditions of azaxylylenes photogenerated via excited-state intramolecular proton transfer (ESIPT) in aromatic o-amido ketones and aldehydes bearing unsaturated functionalities was studied experimentally and computationally. In time-correlated single-photon counting experiments, no relation was found between lifetimes of singlet species and the nature of the ...
Objective(s): Allylbenzenes have been recently developed as inhibitors of lipoxygenases. They decrease peroxidation activity via mimicking 1,4-unsaturated bonds of fatty acids by their allyl portion. We designed and synthesized new derivatives of allyl benzenes (6a-f) with isopropoxy and amide substituents at ortho and meta positions towards allyl group, respectively. ...
