Why does the characteristic colour of gold change when its particles are smaller than 5 nm? Where can such effects be applied in industry today? How can lycopodium be super-hydrophobic and also cause powerful explosions?
How do you get from simple quartz sand to a high-performance wafer and how does the memory effect in shape memory alloys work? Why can lycopodium be super hydrophobic and cause huge explosions at the same time? Or how do smart surface coatings work, e.g. in the automotive industry (flip-flop effect) or in the electronics industry (ITO coatings)?
