Fabrication Of A Polyaniline Ultramicroelectrode Via A Self Assembled Monolayer Modified Gold Electrode
(2013)
Herein, we report a simple and inexpensive way for the fabrication of an ultramicroelectrode and present its characterization by electrochemical techniques. The fabrication of polyaniline UME involves only two steps: ...
Preconcentration of Arsenic in Water Samples Using the Composition-Induced Phase Separation Method and Determination by Etaas
(E D P Sciences, 2013)
A new phase transition microextraction method was developed for determination of trace amount of arsenic ions in water samples in this work. The method is based on the critical point of miscibility of solvents. In this ...
Determination Of Trace Amounts Of Lead With Etaas After Single Drop Microextraction And Dispersive Liquid Liquid Microextraction Methods
(E D P Sciences, 2013)
Two liquid-phase microextraction procedures, single-drop microextraction (SDME) and dispersive liquid-liquid microextraction (DLLME), have been developed for the determination of lead by electrothermal atomic absorption ...
Functionalized Nanoporous Track-Etched B-Pvdf Membrane Electrodes For Heavy Metal Determination By Square-Wave Anodic Stripping Voltammetry
(E D P Sciences, 2013)
Track-etched functionalized nanoporous beta-PVDF membrane electrodes, or functionalized membrane electrodes (FMEs), are electrodes made from track-etched, poly(acrylic acid) (PAA) functionalized nanoporous beta-poly(vinylidene ...
Comparative Study Of Microwave-Assisted And Conventional Synthesis Of Ibuprofen-Based Acyl Hydrazone Derivatives
(Scientific Technical Research Council Turkey-Tubitak, 2013)
A series of potential biological active acyl hydrazone derivatives containing ibuprofen moiety (compounds 4a-4p) was synthesized by the condensation of ibuprofen hydrazone with aromatic aldehydes using conventional and ...
Redox Pathways of Aliskiren Based on Experimental and Computational Approach and Its Voltammetric Determination
(Soc Brasileira Quimica, 2013)
Electrochemical behavior of aliskiren (ALS) was studied via experimental electrochemical methods and theoretical calculations performed at B3LYP/6-31+G (d)//AM1. Cyclic voltammetry studies were carried out based on the ...
Ultrasensitive Detection And Quantification Of Acidic Disaccharides Using Capillary Electrophoresis And Quantum Dot-Based Fluorescence Resonance Energy Transfer
(Amer Chemical Soc, 2013)
Rapid and highly sensitive detection of the carbohydrate components of glycoconjugates is critical for advancing glycobiology. Fluorescence (or Forster) resonance energy transfer (FRET) is commonly used in detection of ...
Using Non-Traditional Writing As A Tool In Learning Chemistry
(Eurasia, 2013)
This study investigated the effect of using a non-traditional writing task and different audiences on 9th grade students' conceptual understanding of a chemistry unit on mixture. 524 students instructed by 3 chemistry ...
