During embryo development, patterns of protein concentration appear in response to morphogen gradients. These patterns provide spatial and chemical information that directs the fate of the underlying ...

A research team has developed a new cathode material that significantly improves the environmental stability and cycling performance of sodium-ion batteries. By designing a radial gradient ...

Diffusion in condensed phases, especially in natural systems such as solutions, geochemical melts and solid–solid interfaces, is an important process that remains poorly understood at a quantitative ...

Biophysicists at Ludwig-Maximilians-Universitaet (LMU) in Munch have developed a new theory, which accounts for the observation that cells can perceive their own shapes, and use this information to ...

If a crystal of a coloured soluble chemical, eg potassium manganate(VII), is placed in water, the particles spread out and mix with the water particles. As well as diffusion occurring between ...
