 One of the most common applications of Kwant is to calculate the conductance of
-a nonoelectronic system.  The plot on the left shows the conductance through a
+a nanoelectronic system.  The plot on the left shows the conductance through a
 2-d electron gas as a function of magnetic flux.  The quantization of
 conductance that is visible (plateaus) is the hallmark of the quantum Hall
-effect.  The third plateau around 1 / Φ = 40 does not develop due to a
-constriction in the system that leads to backscattering.  The situation at this
-value of magnetic field is shown on the right.
