Elastomers obtained by crosslinking of α,ω-bis(glycidylether) poly(dimethylsiloxane) as versatile platforms for functional materials
(Elsevier, 2016-12-19)
Elastomers with an interesting set of properties were synthesized by crosslinking α,ω-bis(glycidylether)poly(dimethylsiloxane,PDMS), using two different strategies. The first one was the anionic homopolymerization of ...
An environmentally friendly triphasic catalytic system: Mn(salen) occluded in membranes based on PDMS/PVA
(ELSEVIER SCIENCE BV, 2010)
The commercially available Jacobsen catalyst, Mn(salen), was occluded in hybrid polymeric membranes based on poly(dimethylsiloxane) (PDMS) and poly(vinyl alcohol) (PVA). The obtained systems were characterized by UV-vis ...
Near infrared emission spectroscopy induced by ultrasonic irradiation
(2006)
Near infrared emission caused by ultrasonic excitation is demonstrated for the first time in this work. The instrument is constituted of an acousto-optical tunable filter-based spectrometer, an ultrasonic processor connected ...
Extraction of polycyclic aromatic hydrocarbons from water samples into a rotating-disk microextractor and the subsequent determination by gas chromatography-mass spectrometry
(Sociedad Chilena de Quimica, 2014)
© 2014, Sociedad Chilena de Quimica. All rights reserved. The rotating disk sorptive extraction (RDSE) technique was applied in this study to the extraction of 16 polycyclic aromatic hydrocarbons (PAHs) in real water ...
Prediction of the penetration of drugs by Artificial Neural Networks
In this study an Artificial Neural Network was developed to predict the penetration of drugs through a polydimethylsiloxane membrane by molecular descriptors. A total of 245 drugs and their absorption experimentally ...
Determination of pesticides in river water using rotating disk sorptive extraction and gas chromatography-mass spectrometry
(Elsevier B.V., 2011)
The rotating disk sorptive extraction (RDSE) technique was applied to the determination of pesticides in aqueous samples. Pesticides of different polarities were considered in this study: chlorpyrifos, diazinon, fenvalarate, ...
Rotating disk sorbent extraction for pre-concentration of chromogenic organic compounds and direct determination by solid phase spectrophotometry
(2011)
A novel and very simple microextraction approach for pre-concentration and direct solid phase spectrophotometric measurement has been developed for the determination of chromogenic analytes. The model analyte to assess ...
