Chemomechanics control of tearing paths in graphene

Tearing of free-standing graphene.

We examine the fracture mechanics of tearing graphene. We present a molecular dynamics simulation of the propagation of cracks in clamped, free-standing graphene as a function of the out-of-plane force. The geometry is motivated by experimental configurations that expose graphene sheets to out-of-plane forces, such as back-gate voltage. We establish the geometry and basic energetics of failure ...

Tearing graphene sheets from adhesive substrates produces tapered nanoribbons.

Graphene is a truly two-dimensional atomic crystal with exceptional electronic and mechanical properties. Whereas conventional bulk and thin-film materials have been studied extensively, the key mechanical properties of graphene, such as tearing and cracking, remain unknown, partly due to its two-dimensional nature and ultimate single-atom-layer thickness, which result in the breakdown of conve...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Control of Neoclassical Tearing Modes for Improved Performance in Iter

Physics and Real Time Control of Tearing modes in TEXTOR

The transport in and around magnetic islands has been studied by measurement of the two dimensional propagation of heat pulses generated by modulated ECRH. Inside an island with a flat temperature profile, the electron heat transport is shown to be strongly reduced with respect to the surrounding plasma. The generalized Rutherford equation is analyzed to determine the relative merits of localiz...
