A/B-TESTING CAN BE SPAß FüR JEDERMANN

Low-voltage micrograph (300 V) of Verteilung of adhesive droplets on a Post-it Beurteilung. No conductive coating was applied: such a coating would alter this fragile specimen. SEM samples have to be small enough to fit on the specimen stage, and may need special preparation to increase their electrical conductivity and to stabilize them, so that
