In the present scenario composite materials are extensively used for structural applications in automobile and aerospace industries. Composite material exhibits a high strength to weight ratio, improved hardness, reduced weight and low coefficient of friction. Because of their enhanced tribological properties helps to achieve low manufacturing cost and(More)
Environment pollution is simply a consequence of the anthropogenic activities of mankind. Emissions from the motor vehicles have been shown to be the major contribution to air pollution in the urban environment. The major pollutants are SO2, No(x) and CO. Of these pollutants carbon monoxide is of utmost importance as the pollutant has serious toxicological(More)
The aim of this study is the modelling and analysis of tool wear on cryogenically treated CNMG120408SMRH13A inserts. Cryogenic treatment is carried out at -196°C for 48 hours, followed by tempering at 200°C for 2 hours. The AISI4340 steel is machined with cryogenically treated inserts by the turning process. Parameters, namely cutting speed, feed rate, and(More)
Silver nanoparticles (Ag NPs) were synthesized by a simple microwave irradiation method using polyvinyl pyrrolidone (PVP) as a capping agent and serine as a reducing agent. UV-Visible spectra were used to confirm the formation of Ag NPs by observing the surface plasmon resonance (SPR) band at 443nm. The emission spectrum of Ag NPs showed an emission band at(More)
