Engineers have found a way to eliminate the fluid flow 'dead zones' that plague the types of electrodes used for battery-based seawater desalination. The new technique uses a physics-based tapered ...

Gases can permeate through 2D channels made from materials like graphene and boron nitride much faster than predicted by theory. The effect can be explained by “specular surface scattering”, which ...

Blood may be thicker than water, but in a narrow enough tube, both liquids flow like treacle. This sluggish behaviour arises because, as you reduce the size of the channel, friction between the liquid ...
