Rhodanine (R) is a heterocycle having complexing properties for heavy metal (HM) ions. Considering the similar electron-donating character of diethylaminobenzene and azulene, electrochemical characterization (Z)-5-(azulen-1-ylmethylene)-2-thioxo-thiazolidin-4-one (R1) 5-(4 diethylamino-benzylidene)-2-thioxo-thiazolidin-4-one (R2) was performed to establish their common features. Chemically modi...

in this paper, multi-wall carbon nanotubes (mwcnts), gold nanoparticles (gnp) and glucose oxidase (god) was developed for the specific detection of glucose. mwcnts were chemically modified with the h2so4–hno3 pretreatment to introduce carboxyl groups which were used to interact with the amino groups of poly(allylamine) (paa) and cysteamine via 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide/n-hy...

0A thin film of cobalt hexacyanoferrate (CoHCF), an analogue of mixed-valence Prussian blue, was deposited electrochemically on the glassy carbon, platinum and gold electrode surfaces in 0.5M KC1 solution. The electrochemical behavior of these modified electrodes show three couples of redox peaks by CV in a supporting electrolyte solution of 0.5M NaCl, whereas for Au modified electrode only ...

Traditional neuronal interfaces utilize metallic electrodes which in recent years have reached a plateau in terms of the ability to provide safe stimulation at high resolution or rather with high densities of microelectrodes with improved spatial selectivity. To achieve higher resolution it has become clear that reducing the size of electrodes is required to enable higher electrode counts from ...

any matrix f can be expressed as a function of the variables a,, instead of p, q, just as in classical theory we can use (6) as well as (7). The correspondence principle then follows from the asymptotic agreement of classical and quantum canonical transformations. It seems, nevertheless, of interest to have proved the correspondence principle as directly as possible without appeal to iterated t...
