Fast electrical discharge milling (fast ED-milling) has become a promising technology in the manufacturing industry for machining complex structures such as diffuser-shaped film cooling holes. However, mechanism of efficient removal materials this is not yet fully understood. To gain further insight into matter, an experimental investigation on morphology craters including absolute material vol...

Mechanical activation in mechanical removal of GaN using diamond tip and mechanochemical Al2O3 are described by the Archard equation mechanically assisted Arrhenius-type kinetic model, respectively. Evident material-removal under elastic contact occurs with assistance interfacial reactions. By analyzing reactions model Hertzian mechanics, critical volume barrier determined semiquantitatively. T...

Among a wide range of pollutants, organic pollutants have given rise to major environmental concerns. Various methods have been considered to mitigate the damage, including catalytic reduction to less hazardous compounds. Catalysts that benefit from high surface area and suitable surface sites for various steps of the catalytic reaction have shown outstanding results in performing such duties. ...
