Nanoscale engineering. View of a NanoScan device, used to characterise the surface of a material on a tiny scale. The scanner can measure the surface shape and map the modulus of elasticity across a sample. This is useful in ensuring consistency of performance of metal alloys at the scale of tens of nanometres (millionths of a millimetre). Photographed in Kazan, Russia.
