In this study, we developed a simple high-throughput and cost-effective method for monitoring toxic metal ion in an environmental aqueous sample. Mercury determination with Sequential Injection Analysis system (SIAs) coupled the electrochemical detection on modified screen-printed carbon working electrode (SPCE) is alternative green analysis of mercury ion. The gold film was used as material im...

Rapid and facile preparation of the cheap modified electrode materials is an important parameter in development of the efficient electrochemical sensor for industrial scale production and mass-market usage. In the present work, the carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) was prepared for sensitive determination of lead (Pb) ion in the presence of bismuth (Bi)...

in order to study the cu(ii) ion selective electrode, an optimized membrane was prepared by mixing of 30 mg of pvc powdered, 5 mg of considered ionophore, 60 mg of plasticizer and 5 mg of additive. the sensor showed a near nernstian response for cu(ii) ions over a concentration range from 1.0×0-6 –1.0×0-2 m with a slope of 28.90.5 mv per concentration decade with a working ph range of 3.5-6.3. ...

During the past decade, tremendous attention has been given to the development of new electrode materials with high capacity to meet the requirements of electrode materials with high energy density in lithium ion batteries. Very recently, cobalt silicate has been proposed as a new type of high capacity anode material for lithium ion batteries. However, the bulky cobalt silicate demonstrates lim...

Applying electrical fields is a simple and versatile method to manipulate and reconfigure optofluidic devices. Several methods to apply electric fields using electrodes on polymers or in the context of lab-on-a-chip devices exist. In this paper, we utilize an ion-implanted process to pattern electrodes within a fluidic channel made of polydimethylsiloxane (PDMS). Electrode structuring within th...

Flow systems for precise and accurate coulometric determinations of ions that were developed on the basis of electrolytic ion transfer at the aqueous|organic solution (W|O) interface are reviewed. The electrolysis cell in the system is composed of a porous poly(tetrafluoroethylene) tube (1.0 mm inner diameter), a metal wire (0.8 mm diameter) inserted into the tube, O into which the tube is imme...

This paper reports the fabrication of a bulk micromachined hybrid torsional micromirror device composed of titanium mirror structures bonded to an underlying silicon sloping electrode structure. The fabrication of the device is enabled by two recent innovations: 1) the Metal Anisotropic Reactive Ion etching with Oxidation (MARIO) Process [1], which provides, for the first time, high aspect rati...

A Li-ion cell typically consists of a carbon-based negative electrode (NE); a porous polymer membrane separator (polypropylene and/or polyethylene); and a lithiated transition metal oxide (LiMxOy, M=Co, Ni, and/or Mn) positive electrode (PE). Electrodes are made by casting slurries of PE or NE-materials, PVDF-binder and carbon-black onto metal current collectors. Mixtures of Li-salts and organi...
