The objective of this work is to study the effect of parameters on resistance spot weld of ASS316 material. In order to study the significance of the process parameters i.e. current, electrode force and weld cycles, towards the percentage improvement in material hardness. It is clear from the results that parameters significantly affect both the mean and the variation in the percentage improvem...

The possibility of substituting Pt/C with the hydrogen storage alloy MlNi3.6Co0.85Al0.3Mn0.3 as the anode active material of a proton exchange membrane fuel cell system has been analyzed. The electrochemical properties indicate that a much more electrochemically active anode is obtained by impregnating the active material loaded anode in a Nafion proton conducting polymer. Such performance impr...

In this work, a one-dimensional Co3O4@TiO2 core-shell electrode material with superior electrochemical performance is fabricated by a convenient and controllable route. The approach involves two main steps: the homogeneous deposition of polydopamine and TiO2 layers in sequence on the cobalt coordination polymer and the thermal decomposition of the polymer matrix. The as-prepared electrode mater...

Surfacing is a technological procedure of applying a layer of filler material to a surface of another material, i.e. a product. By surfacing, it is possible to improve chemical, mechanical, and physical properties of the parent metal, and, consequently, those of the product surfaced. Surfacing may be applied to worn surfaces as well as to new products. A surfacing weld may have the same, simila...

A three-dimensional fast spin-echo MR technique is proposed for locating contact points on implanted intracerebral multicontact electrode bundles, Coronal or sagittal reformatting shows the entire trajectory of the electrode bundles. The contract points are clearly visible owing to the absence of coating material associated with a slightly larger susceptibility artifact. Potentially, this techn...

 Liquid impedance measurements based on capacitive (or contactless) electrodes overcome electrode polarization problems but are affected by stray capacitance from the material being measured to ground, the same as measurements with direct-contact electrodes. This study shows that the effects of that capacitance depend on the impedance being measured and for bipolar impedance measurements they ...

Degradation mechanisms such as lithium plating, growth of the passivated surface film layer on the electrodes and loss of both recyclable lithium ions and electrode material adversely affect the longevity of the lithium ion battery. The anode electrode is very vulnerable to these degradation mechanisms. In this paper, the most common aging mechanisms occurring at the anode during the operation ...

Ordered Mesoporous Carbon (OMC) represents an interesting material for electric double layer capacitors which has the high surface area, easily accessed ordered pore channels and lower production cost. In this work, CMK-3 as promising OMC has been fabricated using the ordered mesoporous silica SBA-15 as a template. The structure and morphology of CMK-3 are characterized by X-ray diffraction...

12-molybdophosphoric acid (PMo12) was encaged into HMOR zeolite by “ship in a bottle”method in aqueous phase which is strongly retained and not easily leached from the host channels.The solid was characterized by XRD prior to using it for the electrode preparation. This compoundwas incorporated with a carbon paste electrode for cyclic voltammetric measurements. PMo12immobilized on the support u...

Electrical Discharge Machine (EDM) parameters have a significant influence on machining characteristic like material removal rate (MMR) and tool wear rate (TWR). Inconel 718, which is widely used in the Medical, Marine, Architectural and food processing industries, is used as a work material. The tool electrode materials used are brass. Experiments are conducted using face centered central comp...
