How a plant regulates its growth

Plants grow towards the light. This phenomenon, which already fascinated Charles Darwin, has been observed by everyone who owns houseplants. Thus, the plant ensures that it can make the best use of light to photosynthesize ...

Gold for iron nanocubes

One of the major challenges in nanotechnology is the precise control of shape, size and elemental composition of every single nanoparticle. Physical methods are able to produce homogeneous nanoparticles free of surface contamination. ...
