Electrochemical discharge micro-machining (micro-ECDM) has the ability to machine electrically nonconducting materials as compared with different existing traditional and also non-traditional machining processes. This paper deals with the effects of different process parameters like applied voltage (V), electrolyte concentrations(wt%), pulse frequency and duty ratio on different machining perfo...

This paper presents the preparation of in situ electrodeposited rGO/MnO2 nanocomposite as a binder-free electrode for supercapacitor application. The work describes and evaluates the performance of prepared electrode via green and facile electrodeposition technique of in situ rGO/MnO2-glucose carbon nanocomposites. The carbon content in the composite electrode increased after GO and D (+) gluco...

This paper studies parameters which affect the pore size diameter of a silicon membrane. Electrochemical etching is performed in characterise the parameter involved in this process. The parameter has been studied is volume ratio of hydrofluoric acid (HF) and ethanol as an electrolyte aqueous for electrochemical etch. This electrolyte aqueous solution has been mixed between HF and ethanol with v...

In present study, molecular dynamics simulation of Cadmium (II), Lead (II) and Copper (II) removal from aqueous electrolyte solutions using the ion-exchange process with the zeolite particles was done. The results showed that, most of the particles had the highest affinity of ion exchanging with Lead (II) and the lowest affinity with Copper (II). The calculated mean ion-exchange ratios showed t...

Solid polymer electrolyte films based on PMMA were prepared in different NaClO4 salt concentrations by solution cast technique. The features of complexion of these electrolytes were studied by X-ray diffraction (XRD). Film morphology was examined by Scanning Electron Microscopy (SEM). The electrical conductivity of pure and NaClO4 doped polymer electrolyte films was studied in the temperature r...

We have directly observed the structural evolution of colloidal crystals as a function of increasing ionic strength using confocal scanning laser microscopy. Silica colloids were sedimented onto a glass substrate in deionized water to create large, single domain crystals. The solution ionic strength was then increased by one of three methods of controlled electrolyte addition: (1) direct inject...

Dehydration is the danger signal of infantile diarrhoea because without dehydration the mortality from properly treated gastro-enteritis should be negligible, hence the importance of preventing dehydration and the recognition that its presence indicates a medical emergency. Important constituents of both extracellular and intracellular body fluids are the electrolytes, and Gamble (1947) conside...
