Current Micro Electrode Arrays used in the field of neural prosthetics are typically composed of an electrode plus structural support. These chronically implanted combinations can cause persistent scarring which can extend out to 250μm in radius from a typical 15μm width silicon shank. This scarring, along with localized neuronal death and gliosis, makes detecting neuronal activity very difficu...

in the present work, an efficient modified carbon-ceramic electrode by multi-walled carbon nanotubes/ionic liquid nanocomposite (mwcnts/il/cce) was prepared through a simple and repeatable procedure. the introduced modified electrode was used for the study of the electrochemical behaviour and determination of tryptophan (trp) in the presence of uric acid (ua) using cyclic voltammetry (cv), diff...

in this work poly eriochrome black t (ebt) was electrochemically synthesized on the glassy carbon electrode as electrode modifier. on the modified electrode, voltammetric behavior of isoniazid (inh) was investigated. the poly (ebt)-modified glassy carbon electrode has excellent electrocatalytic ability for the electrooxidation of isoniazid. this fact was appeared as a reduced overpotential of i...

the microbial fuel cells (mfcs) are a kind of systems through which the anaerobic bacteriaalong with the oxidation of simple or complicated organic matter in the wastewater can generate the electricpower. this is a modern approach used in generation of the clean and renewable energy. in this research, two pilot laboratories of double-chamber microbial fuel cells were made. one of them contained...

this article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. the electrostatic actuation was induced by applying ac-dc voltage between the microbeam and electrode plate. in contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. in additio...

Electrode Reactions A typical electrode reaction involves the transfer of charge between an electrode and a species in solution. The electrode reaction usually referred to as electrolysis, typically involves a series of steps: * Reactant (O) moves to the interface: this is termed mass transport * Electron transfer can then occur via quantum mechanical tunnelling between the electrode and reacta...

Introduction One task during development and control of bioprocesses used for production of recombinant proteins is to deliver fast, accurate and reliable analytical process data. Monitoring of nutrients and metabolites in animal or bacterial cell culture is essential to avoid limitations or toxic accumulation during fermentations that can effect cell growth, viability, product yield and qualit...

Aluminum(III) porphyrins are examined as potential fluoride selective ionophores in polymeric membrane type ionselective electrodes. Membranes formulated with Al(III) tetraphenyl (TPP) or octaethyl (OEP) porphyrins are shown to exhibit enhanced potentiometric selectivity for fluoride over more lipophilic anions, including perchlorate and thiocyanate. However, such membrane electrodes display un...
