It has recently been shown that superconductivity in magic-angle twisted trilayer graphene survives to in-plane magnetic fields are well excess of the Pauli limit, and much stronger than critical bilayer graphene. The difference is surprising because bilayers trilayers both support flat bands thought be fountainhead superconductivity. We show here can traced a $\mathcal{C}_2 \mathcal{M}_{h}$ sy...

On the ground of manufacturing, sheet metal parts play a key role as they cover about half of the production processes. Sheet metals are commonly obtained from rolling and forming processes which causes misalignment of micro structure resulting obvious anisotropic characteristics and micro cracks. Presence of micro cracks poses serious attention, when stresses at the tip reach to the critical v...
