This paper presents the Optimization of Non-Traditional Machining (NTM) process for the Electrochemical Machining Process by Particle Swarm Optimization Technique. The main aim of the work is to find the optimum values of machining parameters. The NonTraditional or Unconventional Machining Process has proved to be better than conventional machining process to a large extent. Keywords—Convention...

A facile enzyme-free hydrogenperoxide electrochemical sensorwas fabricated based onmultilayer ultrathin film containing Naphthol green B anions (NGB) and exfoliated nanosheets of Co–Al layered double hydroxide (LDH) via layer-by-layer self-assembly technique. The X-ray diffraction pattern indicates the superlattice structure of the filmwith repeating distance of 4.15nm; SEM and AFM images show ...

A three electrodes planar electrochemical sensor, based on CuO nanowires growth “in situ” on Cu working electrode, was fabricated by a simple micromachining technique and employed for the non-enzymatic determination of glucose. The microstructural and morphological characteristics of the modified electrode was investigated by XRD and SEM analysis. Cyclic voltammetry and chronoamperometric measu...

A hybrid ultramicroelectrode containing one micro-carbon electrode and one empty micro-channel was employed to be a micro-electrochemical cell and a mass spectrometric nanospray emitter. This setup can combine MS with an electrode directly and provide in situ information about an electrochemical reaction. The mechanisms proposed by Bard et al. for a Ru(bpy)32+ (bpy = 2,2'-bipyridine) electroche...

This paper reports on molecular-based magnetic thin films of Prussian blue analogues (PBA) with high critical temperatures composed of mixed-valence chromium cyanides. The thin films of PBA were synthesized by means of electrodeposition technique. Morphology and magnetic study are presented in a function of electrochemical deposition conditions. We present the electrochemical methods as a promi...

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...

Electrochemical immunosensors have emerged as a highly sensitive and rapid technique for the detection of specific pesticide based on the immunological interactions between the binding biomolecules (antibody or hapten) onto the transducer interface and the target analyte (hapten or antibody). In terms of the development of electrochemical immunosensors, the antibody (Ab) /hapten immobilization ...

A technique that combines scanning electrochemical microscopy (SECM) and optical microscopy (OM) was implemented with a new probe tip. The tip for scanning electrochemicaVoptical microscopy (SECM/OM) was constructed by insulating a typical gold-coated near-field scanning optical microscopy tip using electrophoretic anodic paint. Once fabricated, the tip was characterized by steady-state cyclic ...

The development of an electrochemical detector to monitor the in situ formation of biofilms is described. The detector consisted of an electrochemical cell containing three electrodes, whose response to the application of a potential profile to the working electrode was sensitive to the amount of biofilm present on the surface. The electrochemical technique used was repetitive cyclic voltammetr...

A novel electrochemical sensing method was devised for the first time to detect plasma cortisol, a potential psychological stress biomarker, in human immunodeficiency virus (HIV)-positive subjects. A miniaturized potentiostat (reconfigured LMP91000 chip) interfaced with a microfluidic manifold containing a cortisol immunosensor was employed to demonstrate electrochemical cortisol sensing. This ...
