the mechanistic aspects of the electrochemical reduction of u(v1) nitrate at a mercury electrode in chloroform, using three different supporting electrolytes, are described. in the presence of tetrabutylarnmonium perchlorate (tbap) as a neutral electrolyte, uo (no ) , reduced in two irreversible electrochemical steps to form a u(v1)-u(v) binuclear complex and u(iv), respectively. in the presenc...

in this study, the effects of forming method (extrusion) and environmental factors (solution ph and temperature) on the corrosion performance of az91 magnesium alloys were investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (eis), scanning electron microscopy (sem) and salt spray techniques. the polarization test results of the specimens showed that simple sh...

this study presents a review on advanced oxidation processes (aop) for simultaneous removal of no and so2. aop is based on using a strong oxidant such as ozone and h2o2 which is able to generate highly reactive intermediates. the pollutant will be oxidized and removed by these intermediates. in recent years, aop has been considered as an effective and attractive technology in the field of flue ...

Tremendous efforts have been dedicated into the development of high-performance energy storage devices with nanoscale design and hybrid approaches. The boundary between the electrochemical capacitors and batteries becomes less distinctive. The same material may display capacitive or battery-like behavior depending on the electrode design and the charge storage guest ions. Therefore, the underly...

The authors have applied an advanced set of auto-regressive tools for identifying potentially complex, linear and nonlinear relationships in data, wherein the underlying physical relationships are not well described. In this paper these tools and techniques are described in detail, and the results of the application of these tools to evaluation of diesel engine lubricating oil health (based on ...

Electrochemical machining (ECM) is a nontraditional manufacturing process that can machine difficult-to-cut materials. In ECM, material is removed by controlled electrochemical dissolution of an anodic workpiece in an electrochemical cell. ECM has extensive applications in automotive, petroleum, aerospace, textile, medical, and electronics industries. Improving current efficiency is a challengi...

Besides, EIS is few that proven useful membrane fouling detection. Electrodes are some most essential components analytes detection with EIS. With advances in printing technology, fabrication advanced printed electrode sy...

Distillery industry is recognized as one of the most polluting industries in India with a large amount of annual effluent production. In this present study, the optimization of electrochemical treatment process variables was reported to treat the color and COD of distillery spent wash using Ti/Pt as an anode in a batch mode. Process variables such as pH, current density, electrolysis time, and ...

From the bench-mark work on microfluidics from the Whitesides's group in 2007, paper technology has experienced significant growth, particularly regarding applications in biomedical research and clinical diagnostics. Besides the structural properties supporting microfluidics, other advantageous features of paper materials, including their versatility, disposability and low cost, show off the gr...

Simultaneous acquisition of in vivo electrophysiological and neurochemical information is essential for understanding how endogenous neurochemicals modulate the dynamics of brain activity. However, up to now such a task has rarely been accomplished due to the major technical challenge of operating two independent recording systems simultaneously in real-time. Here we propose a simpler solution ...
