Citric acid fermentation by mutant strain of Aspergillus niger GCMC-7using molasses based medium
(Pontificia Universidad Católica de Valparaíso, 2002)
Electrochemical sensing platform based on polyelectrolyte-surfactant supramolecular assemblies incorporating carbon nanotubes
(American Chemical Society, 2011-10)
The characterization and application of a polyelectrolyte-surfactant supramolecular assembly formed by poly(allylamine) and dodecyl sulfate (PA-DS) on a screen-printed graphite electrode for the preparation of electrochemical ...
Obtaining relief structures in silver halide materials
(Sociedad Espanola de Optica, 2013-01-01)
Diffraction transmission gratings were recorded in AGFA-8E75 film, chemically treated under processes with D-19 + potassium ferrocyanide and a chemical processing technique proposed for PE-2 film to obtain embossed stripes. ...
Copper Hexacyanoferrate Formation on the Modified Silica Surface with DAB-Am-16 Dendrimer
(Wiley-v C H Verlag Gmbh, 2011-01-01)
The third generation (G-3) polypropylenimine hexadecaamine dendrimer (DAB-Am-16) was grafted onto the silica gel surface. The modified silica interacts easily with Cu(2+) and then with potassium ferrocyanide to form copper ...
Renewable drops electrochemical sensor for sulfide ions detection

Influence of normal and radial contributions of local current density on local electrochemical impedance spectroscopy
(Pergamon-Elsevier Science LtdOxford, 2012)
A new tri-electrode probe is presented and applied to local electrochemical impedance spectroscopy (LEIS) measurements. As opposed to two-probe systems, the three-probe one allows measurement not only of normal, but also ...
Construction and Evaluation of an Opto-Coupled Potentiostat with a PC/PDA Interface
(TAYLOR & FRANCIS INC, 2008)
The design, construction, and characterization of a portable opto-coupled potentiostat are presented. The potentiostat is battery-powered, managed by a microcontroller, which implements cyclic voltammetry (CV) using suitable ...
