Why does an eraser erase the pencil ?

 · To erase it, use the blue end of the eraser. It consists of fine particles of pumice stone that will allow to damage the paper a little more during the rubbing and to remove the part of the paper which has been tinted. An eraser is much more effective because it acts by chemical reaction . The ink remains on and in the paper but becomes colorless.

Antisymmetric magnetoresistance in van der Waals …

Although the resistivity of graphite is 10 4 orders smaller than that of FGT, these spin currents will still be flowing through the two FGT/graphite interfaces. Because the thicknesses of our graphite layers, which are 2 to 11 nm, are much smaller than the electron mean free path in graphite ( 45 ), the electrons transported through the graphite can enter the FGT layers and scatter within them.
