Particle impact is technologically important and can cause significant damage to a surface. Detecting the approach of particle would give key information on process. High-speed imaging this process gives particle's velocity movement but does not answer questions relating changes in electrochemical properties surface caused by resultant impact. Furthermore, it difficult apply non-transparent med...

Zn–air fuel cells are promising energy storage devices for renewable and power sources, as they cost-effective have high density. However, limited charge discharge cycles low round-trip efficiency long been obstacles to large-scale market deployment. Herein, a new fluidized-bed zinc–air cell is designed, constructed, tested, characterized. The integration of the fluidized bed in leads key advan...

Abstract Graphene has numerous potential applications in ultrathin electronics. There an electrode should function contact with fluids and under mechanical stress; therefore, its stability is specifically of concern. Here, we explored a custom-made quartz crystal microbalance (QCM) sensor covered wet-transferred large-scale monolayer graphene for investigation behavior. Monolayer was found to b...

In this study, electrode wear caused by machining from cold work tool steel with heat treated 60-62 HRC hardness was investigated using electro erosion method and Cupro MAX CuCrZr electrode. The workpiece material are eroded melting evaporation as a result of the electrical arc (sparking) that occurs between in dielectric environment. These erosions can be interpreted changes form measurements ...

The electro discharge machining (EDM), one of the methods used in the machining industry and a non-traditional manufacturing method, the electro erosion process does not depend on the hardness of material and offers a way to process materials of very complex geometry with very fine and high precision by using cheap electrode materials, which make it a preferred method. In this study, effect of ...
