Grazing angle photoluminescence of porous alumina as an analytical transducer for gaseous ethanol detection
(American Scientific Publishers - ASPValencia, 2014-09)
Porous alumina was used to build an optical sensor for gaseous ethanol detection. The photoluminescence collected in a grazing angle was used as a transducer signal. The photoluminescence detected with this optical setup ...
Rapid and sensitive method for the determination of acetaldehyde in fuel ethanol by high-performance liquid chromatography with UV-Vis detection
(Springer, 2005-04-01)
A high-performance liquid chromatography (HPLC) method for the determination of acetaldehyde in fuel ethanol was developed. Acetaldehyde was derivatized with 0.900 mL 2,4-dinitrophenylhydrazine (DNPHi) reagent and 50 mu L ...
Determination of aldehydes and ketones in fuel ethanol by high-performance liquid chromatography with electrochemical detection
(Vieweg, 2006-01-01)
A new methodology was developed for analysis of aldehydes and ketones in fuel ethanol by high-performance liquid chromatography (HPLC) coupled to electrochemical detection. The electrochemical oxidation of 5-hydroxymetkylfurfural, ...

Ethanol-induced tolerance and sex-dependent sensitization in preweanling rats
(Pergamon-Elsevier Science Ltd, 2015-02)
According to genetic studies, the acute stimulating effect of ethanol seems to be associated with an increased predisposition to consume large quantities of ethanol. Ethanol-induced stimulation has been rarely reported in ...
Spectrophotometric determination of sulphate in automotive fuel ethanol by sequential injection analysis using dimethylsulphonazo(III) reaction
(2006)
A sensitive SIA method was developed for sulphate determination in automotive fuel ethanol. This method was based on the reaction of sulphate with barium–dimethylsulphonazo(III) leading to a decrease on the magnitude of ...
Immediate human pulp response to ethanol-wet bonding technique
(2015)
To evaluate the short-term response of human pulps to ethanol-wet bonding technique. Methods Deep class V cavities were prepared on 17 sound premolars and divided into three groups. After acid-etching, the cavities from ...
Determination of sulfate in ethanol fuel using an electrode chemically modified with polypyrrole by flow injection analysis
(2010)
In this work, an electrode chemically modified with polypyrrole (PCME) was employed for determination of sulfate in ethanol fuel using a FIA system. The PCME was prepared by polymerization of pyrrole at a glassy carbon ...
