BACKGROUND Dopamine is a potent neuromodulator in the brain, influencing a variety of motivated behaviors and involved in several neurologic diseases. Measurements of extracellular dopamine in the brains of experimental animals have traditionally focused on a tonic timescale (minutes to hours). However, dopamine concentrations are now known to fluctuate on a phasic timescale (subseconds to seco...

As the electrochemical method, the Fast Fourier Transform (FFT) Stripping Cyclic Voltammetry detection method was designed for measurement and monitoring of adsorbed mercury ions by new modified adsorbent based on mesoporous silica as a new adsorbent. In this respect, SBA-15 as mesoporous silica and 1, 3, 5 Trithiane as effective modifier ligand were chosen, and the modification process was car...

Potentiostatic, galvanostatic and cyclic potentiodynamic depositions of polyaniline were studied by cyclic voltammetry and in-situ Raman spectroscopy. Multivariate analysis of the spectroelectrochemical data including evolving factor analysis, multivariate curve resolution and 2Dcorrelation spectroscopy was applied to resolve overlapped bands in Raman spectra and to assign them reliably. Oxidiz...

Supercapacitive properties of synthesised metal oxides nanoparticles (MO where M = Ni, Co, Fe) integrated with multi-wall carbon nanotubes (MWCNT) on basal plane pyrolytic graphite electrode (BPPGE) were investigated. Successful modification of the electrode with the MWCNT-MO nanocomposite was confirmed with spectroscopic and microscopic techniques. Supercapacitive properties of the modified el...

     Clinical and Epidemiological studies have shown that a diet rich in fruits and vegetables is associated with a decreased risk of cardiovascular diseases, cancers and other related disorders. These beneficial health effects have been attributed in part to the presence of antioxidants in dietary plants. Therefore screening for antioxidant properties of plant extracts has been one of the inte...

a nanocomposite of polyaniline (pani) with natural clinoptilolite (clino) was prepared by chemical oxidative polymerization of anilinium cations in the presence of clinoptilolite dispersion. the pani/clino nanocomposite was characterized using ftir, xrd and sem techniques as well as electrical conductivity measurement using four point probe technique. cyclic voltammetry analysis was used to inv...

glassy carbon (gc) is the most commonly used carbon-based electrode in the analytical laboratory. because of the high background current and low electrode response, modification of this electrode can be done by various materials and techniques. an ionic liquid (il), 1-methyl-3-(3-trimethoxysilyl propyl) imidazoliumbis (trifluoromethylsulfonyl) imide, was covalently cross linked onto the gc surf...
