Fabrication of cu based metal-organic framework / graphene Nanocomposite and study electrochemical performance in supercapacitors

High conductivity and high level of electrolyte availability are the main requirements of active materials used in supercapacitors (SCs) to achieve high electrochemical efficiency. In recent years, metal-organic frameworks (MOFs) have been used as electrode materials for SCs due to their suitability of porosity and high surface area. However, using single-component MOFs in supercapacitors resul...

Optimization of machining parameters and wire vibration in wire electrical discharge machining process

Background: Wire Electrical discharge machining (WEDM) has higher capability for cutting complex shapes with high precision for very hard materials without using high cost of cutting tools. During the WEDM process, the wire behaves like a metal string, straightened by two axial pulling forces and deformed laterally by a sum of forces from the discharge process. Major forces acting on the wire c...

Cost- Tolerance Prediction Models for Electrochemical Machining of Metal Matrix Composites

Article history: Received: 27.10.2014. Received in revised form: 11.12.2014. Accepted: 12.12.2014. Electrochemical machining (ECM), is an advanced manufacturing technique capable of machining hard composite materials with good tolerance. However, the huge investment and operating costs make the ECM process uneconomical. This work is hence intended to develop cost-tolerance relationship for ECM ...

Mathematical Modelling of Electrochemical Machining Processes

The solution to free boundary problems arising from electrochemical machining processes is considered. A mathematical description of the machining process is presented with particular consideration given to its electrochemical properties and to the appropriateness of its treatment as a potential problem with Dirichlet boundary conditions. A number of different machining configurations are consi...
