Microbial electrolysis cell (MEC) is a gripping bio-electrochemical device producing H2 gas from renewable biomass while at the same time treat wastewater.  Through extensive global research efforts in the latest decade, the performance of MECs, including energy efficiency, hydrogen production rate (HPR), and hydrogen recovery have achieved significant breakthroughs. However, employi...

An indium tin oxide glass electrode coated with poly(3,4-ethylenedioxythiophene), PEDOT, PEDOT-ITOE, was proposed as an electrode workable as both a reference electrode and a counter one, a reference/counter electrode, in an organic phase and applied to a thin-layer cell of a two-electrode system for voltammetry at the liquid | liquid interface. By oxidizing the PEDOT film by 50% and doping a s...

A glass capillary ultramicroelectrode (tip diameter approximately 1.2 microm) having an electrokinetic sampling ability is described. It is composed of a pulled glass capillary filled with an inner solution and three internal electrodes (Pt working and counter electrodes and an Ag/AgCl reference electrode). The voltammetric response of the capillary electrode is based on electrokinetic transpor...

Electrostatic driving and capacitive detection is widely used in micro hemispheric shell resonators (HSR). The capacitor gap distance is a dominant factor for the initial capacitance, and affects the driving voltage and sensitivity. In order to decrease the equivalent gap distance, a micro HSR with annular electrodes fabricated by a glassblowing method was developed. Central and annular cavitie...

The nickel phosphide thin films were electrochemically deposited on FTO glass (3.1 mm thick, 13 Ω/ , Nippon Sheet Glass) using potentiostatic (PS) and periodic pulse-reverse (PR) techniques at room temperature in a homemade three-electrode cell. FTO, Pt foil, and SCE (saturated calomel electrode) were used as the working, auxiliary, and reference electrodes, respectively. The deposition bath co...

A single walled carbon nanotube (SWCNT)-based three-electrode system was fully integrated on glass substrates using a standard microfabrication process and electrochemically characterized using cyclic voltammetry. O(2) plasma functionalization of the SWCNT film working electrode for achieving high sensitivity was voltammetrically optimized with respect to the plasma power and treatment time. Ch...

current study is aimed to compare fluride release in conventional glass ionomer, light-cured glass ionomer and compomers. standard samples from the aforementioned materials were prepared and measured by selective fluride ion electrode in intervals of 24hours, 1,2,3 and 4 weeks in neutral ph of 7 and acidic ph of 4.5. the obtained data represented that fluride ion release decreased in time but t...

In this work the critical aspects of the process sequence developed for fabrication of hybrid polymer microfluidic systems integrating metal electrode pattern and precisely aligned microfluidic structure are discussed in details. Glass and polycarbonate were considered as primary transparent substrate materials for metal (Au, Pt) electrode deposition and the microchannels were formed in multi-l...

A glass electrode apparatus is described with which pH measurements can be made with as small volumes as 2 drops (about 0.14 cc.) of solution. Using this apparatus the change of pH of the vacuolar sap of Nitella, due to the penetration of brilliant cresyl blue, has been readily followed. The sap and the dye have been found to poison the usual type of hydrogen electrode.

Complex electrical-conductivity experimental data sets for the interfacial amorphous phase in copper-core-copper-oxide-shell nanostructured composites have been analyzed using two Kohlrausch-related frequency response models recently developed for analysis of the dispersive electrical response of conductive materials. Such analysis has been carried out for both the precursor (herein referred to...
