Green tea glycolic extract-loaded liquid crystal systems: development, characterization and microbiological control
(Univ Sao Paulo, Conjunto Quimicas, 2016-07-01)
Liquid crystal systems (LCSs) have interesting cosmetic applications because of their ability to increase the therapeutic efficiency and solubility of active ingredients. The aim of the present research was to develop green ...
Benzene solubility in ionic liquids: working toward an understanding of liquid clathrate formation
(Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim, 2014)
The solubility of benzene in 15 imidazolium, pyrrolidinium, pyridinium, and piperidinium ionic liquids has been determined; the resulting, benzene-saturated ionic liquid solutions, also known as liquid clathrates, were ...
A simple, rapid and novel method based on salting-out assisted liquid–liquid extraction for ochratoxin A determination in beer samples prior to ultra-high-performance liquid chromatography coupled to tandem mass spectrometry
(Taylor & Francis, 2018-08)
A novel, simple, easy and cheap sample treatment strategy based on salting-out assisted liquid-liquid extraction for ochratoxin A (OTA) ultra-trace analysis in beer samples using ultra-high-performance liquid chromatography-tandem ...
Ultrasound-assisted dispersive liquid–liquid microextraction of tetracycline drugs from egg supplements before flow injection analysis coupled to a liquid waveguide capillary cell
(2016-09-01)
A simple, rapid, and efficient ultrasound-assisted dispersive liquid–liquid microextraction (US-DLLME) method was developed for extraction of tetracycline residues from egg supplement samples, with subsequent determination ...
Degradation of the Oxirane Ring of Epoxidized Vegetable Oils in a Liquid-liquid-solid Heterogeneous Reaction System
(Elsevier Science Sa, 2007-12)
The main oxirane-ring opening reactions that occur during the manufacture of epoxidized vegetable oils using a strongly acidic, gel-type ionexchange resin (IER) (Amberlite IR-120, 8% crosslinking) were analyzed. By using ...
Estudio de viabilidad para crear una empresa en la ciudad de Pereira, para producir y comercializar un sistema de monitoreo y control de inventarios de líquidos
(Universidad Católica de Pereira, 2014)
A fast-multiclass method for the determination of 21 endocrine disruptors in human urine by using vortex-assisted dispersive liquid-liquid microextraction (VADLLME) and LC-MS/MS
(2020-10-01)
Simplicity, speed, and reduced cost are essential demands for routine analysis in human biomonitoring studies. Moreover, the availability of higher volumes of human specimens is becoming more restrictive due to ethical ...
