the electrochemical behavior of nifedipine (i), nitrendipine(ii) and their photodegradation products has been studied by employing electrochemical techniques in chloroform and in 1:4 mixture of chloroform-isopropanol using piperidinium perchlorate (ppc) as supporting electrolyte. it has been shown that i and ii undergo in a 4e, 4h+ irreversible reduction reaction, while the reduction product, p...

The road from theory to practice takes many steps, often over or around considerable obstacles. This certainly holds for the process industries, where actual conditions are rather unfavourable for control complexity and sophistication: process behaviour varies significantly and sometimes even qualitatively due to feed and product changes, unavailability of process equipment, lack of manpower fo...

Both empirical and anecdotal evidence indicate that enterprises across the globe and in various industries, such as finance, healthcare and government, tend to collect hundreds if not even thousands of business process models over time [1-5]. It is quite common that such set of industry-strength business process models includes thousands of activities and further related objects such as data, a...

background: electrochemical methods, as one of the advanced oxidation processes (aops), have recently been applied to remove different contaminants from water and wastewater. this study compares the performance of anodic oxidation (ao) and electro-fenton (ef) methods on waste sludge treatment. methods: this experimental study was performed on real sludge and the effect of operating parameters s...

A new electrochemical model has been carefully established to explain the carbonation behavior of cement mortar, and the model has been validated by the experimental results. In fact, it is shown by this study that the electrochemical impedance behavior of mortars varies in the process of carbonation. With the cement/sand ratio reduced, the carbonation rate reveals more remarkable. The carbonat...

Arvia®, a spin-out company o Manchester, UK is commercialising a water treatm the removal of low concentrations of organics technology is based on the adsorption of organics o adsorbents coupled with their electrochemical simple electrochemical cell. In this paper, the poten to adsorb microorganisms and electrochemicall present in water has been demonstrated. Bench have indicated that the proce...

This paper presents an overview of the design of electrochemical processing equipment for semiconductor and related microelectronic manufacturing as well as a review of publications that are applicable to electrochemical wafer process equipment. We discuss several types of electrochemical processes applicable to wafer processing and the considerations that go into automated equipment for these ...

Treatments of estrogens such as Estrone (E1), Estradiol (E2) and Ethinylestradiol (EE2) were conducted using an electrolytic reactor equipped with multi-packed granular glassy carbon electrodes. Experimental results showed that E1, E2 and EE2 were oxidized in the range of 0.45-0.85 V and were removed through electro-polymerization. Observed data from continuous experiments were in good agreemen...

An ultrathin Ni/Ni(OH)2 hybrid electrode has been synthesized using a controlled reverse pulse modulated electrochemical approach and demonstrated as an advanced pseudocapacitor material having a remarkable specific capacitance and excellent cycling performance.
