Diclofenac is a drug with an analgesic effect that accumulates and results in adverse consequences if it enters the human body more than needed. Low concentrations of diclofenac have been detected in different water sources through leachates of landfills and agricultural areas, human and animal excreta expired drug discharge and hospital effluents. To eliminate diclofenac from the aquatic e...

Alkaline chlorination, an efficient but high chemical cost process, is commonly employed for cyanide (CN−) removal from CN-rich wastewater streams. CN− and recovery through the precipitation of Prussian Blue (Fe4III[FeII(CN)6]3, PB) or Turnbull’s (Fe3II[FeIII(CN)6]2, TB) were realized using iron salts, leading to a cost-effective sustainable process producing valuable product. However, PB TB hi...

A novel parylene-embedded carbon nanotube nanoelectrode array is presented for use as an electrochemical detector working electrode material. The fabrication process is compatible with standard microfluidic and other MEMS processing without requiring chemical mechanical polishing. Electrochemical studies of the nanoelectrodes showed that they perform comparably to platinum. Electrochemical pret...

Workflow technology has not yet lived up to its expectations not only because of social problems but also because of technical problems, like inflexible and rigid process specification and execution mechanisms and insufficient possibilities to handle exceptions. The aim of this paper is to present a workflow model which significantly facilitates the design and reliable management of complex bus...

The underpotential deposition(UPD) phenomena is very interesting not only because of its fundamental importance but also due to its noticeable growing impact on the material science. The amazing possibility of control the deposition process down to monolayer results in new kind of materials with different properties than bulk ones embracing they catalytic, electronic or magnetic properties. Exc...

the applications of electrochemical machining are increasing because of increasing requests of industries for materials with high strengh and high hardness. regular ecm uses a tool with spicified profile shape that is similar to final shape of workpiece. in this reasearch a nozzle that delivers electrolyte to the machining gap is used for machining cylinderical workpieces. by moving the electro...
