Lithium-Sulfur (Li-S) batteries are considered as one of the promising candidates for next-generation Li batteries in near future. Although, these batteries are suffering from certain drawbacks such as rapid capacity fading during the charge and discharge process due to the dissolution of polysulfides. In this paper, Sulfur/metal oxide (TiO2 and SiO2) yolk–shell structures have been successfull...

There is much recent interest in graphene-based composite electrode materials because of their excellent mechanical strengths, high electron mobilities, and large specific surface areas. These materials are good candidates for applications in supercapacitors. In this work, a new graphene-based electrode material for supercapacitors was fabricated by anchoring carbon dots (CDs) on reduced graphe...

Electrical discharge machining (EDM) is a non conventional manufacturing process which is used for shaping hard metals and forming deep complex shaped profiles by arc erosion in all kinds of electro-conductive materials. The objective of this paper is to study the influence of process parameters and electrode shape configuration on the machining characteristics such as surface quality, material...

BICUVOX.10 (Bi Cu V O ) might be a very attractive material for use in oxygen sensors, fuel cells and oxygen 2 0.1 0.9 5.35 separators. The electrochemical stability of BICUVOX.10 is an important factor for its future application. The electrochemical reduction and oxidation can be recognized very easily by the voltammetric technique.
