Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete. For the first time, ...
From atomic crystals to spiral galaxies, self-assembly is ubiquitous in nature. In biological processes, self-assembly at the molecular level is particularly prevalent. Phospholipids, for example, ...
Researchers have developed a new way of making surfaces that can actively control how fluids or particles move across them. The work might enable new kinds of biomedical or microfluidic devices, or ...
The movement and space between particles in a fluid affects the amount of pressure the fluid exerts. This means that the pressure in a fluid changes depending on its height, depth and temperature. The ...
If you’ve watched any England football games recently, this news might not surprise you. Footballers seem to move across the pitch in much the same manner as particles move in a chaotic flow of fluid.
Lacquers, paint, concrete—and even ketchup or orange juice: Suspensions are widespread in industry and everyday life. By a suspension, materials scientists mean a liquid in which tiny, insoluble solid ...
ETH Zurich Materials Scientists are the first to measure the microscopic forces involved when particles in suspensions such as concrete or paint roll past each other. Previously, such measurements ...
