Iron oxide submicron wires are successfully synthesized via a microwave irradiation method within a short period of 20 s. Upon reduction, this material shows orders of magnitude faster Cr(VI) removal rate than conventional adsorbents. A redox reaction based removal mechanism is revealed instead of adsorption.

Medium Carbon Steel AISI 1045 has a wide variety of applications in vehicle component parts & machine building industry. Surface roughness and Material Removal Rate are the main quality functions in high speed turning of medium carbon steel in dry conditions. In this study, the optimization of two response parameters (Surface roughness and Material Removal Rate) by three machining parameters (c...

One of the main goals of the metal-mechanical industries is the reduction of the production costs through the productivity increase. In the attempt to reach this goals, many researchers have been used the hot machining method. This method consists, basically, in the heating of the work piece hundreds of degrees Celsius above room temperature with aid of an external source of heat. Thus, the red...

six different composite packaging materials were tested with the trades’ practice of polythene bags in storing smoked catfish for a period of six months. the thickness of the packaging materials ranges from 0.23 to 046 mm with water and oil absorption rates of the packaging materials varies from 0.23 to 10.00 and 0.28 to 10.857 glcm2/mm respectively. the impact resistance weight also varies fro...

Electrical Discharge Machine (EDM) is especially used for the manufacturing of 3-D complex geometry and hard material parts that are extremely difficult-to-machine by conventional machining processes. In this paper authors review the research work carried out in the development of die-sinking EDM within the past decades for the improvement of machining characteristics such as Material Removal R...
