Ultrasound-assisted synthesis of novel chalcone, heterochalcone and bis-chalcone derivatives and the evaluation of their antioxidant properties and as acetylcholinesterase inhibitors
(2019)
The chalcone and bis-chalcone derivatives have been synthesized under sonication conditions via Claisen-Schmidt condensation with KOH in ethanol at room temperature (20-89%). The structures were established on the basis ...
Distribution and pollution assessment of trace elements in marine sediments in the Quintero Bay (Chile)
(2015)
The aim of this study was to assess the levels of heavy metal pollution in the clay/silt fraction (<63 mu m fraction) of marine sediments from Quintero Bay, Chile. For this, sediment samples were collected from 14 sites ...
CuO urchin-nanostructures synthesized from a domestic hydrothermal microwave method
(Pergamon-Elsevier B.V. Ltd, 2008-03-04)
This letter reports the synthesis of CuO urchin-nanostructures by a simple and novel hydrothermal microwave method. The formation and growth of urchin-nanostructures is mainly affected by the addition of polyethylene glycol ...
