Brings the Band Structure of Carbon-Based Devices into the Limelight

A shift to carbon is positioning biology as a process of synthesis in mainstream engineering. Silicon is quickly being replaced with carbon-based electronics, devices are being reduced down to nanometer scale, and further potential applications are being considered. While traditionally, engineers are trained by way of physics, chemistry, and mathematics, Nanoelectronics: Quantum Engineering of Low-Dimensional Nanoensembles establishes biology as an essential...

Dissimilar-metal joints are used widely in various industrial applications due to both technical and economic reasons. The materials used for high temperature applications are subjected to hot corrosion and high temperature wear.The present work deals with to evaluate the behaviour of un-welded and dissimilar weldments of AISI 304 steel and 20MnMoNi55 steel made by TIG welding at temperature 900°C, samples when exposed to high temperature oxidation in air and molten 75%wt sodium sulphate + 25%wt potassium sulphate salt under cyclic condition. Compare the oxidation and hot corrosion...
