Using Einstein's tea leaf paradox to study nanofluids

Stirring can allow the dispersion of substances evenly in liquid. Einstein's tea leaf paradox is a concept that shows how tea leaves can concentrate in a doughnut shape through a secondary flow effect during stirring. In ...

Self-driving synchrotron coherent X-ray scattering on complex fluids

Soft materials are ubiquitous in our daily lives, from the food we eat to the products we use to the materials that make up our bodies. Some examples of soft materials include cream, toothpaste, and blood. Most soft materials ...

Scientists design novel nonlinear circuit to harvest clean power using graphene

Obtaining useful work from random fluctuations in a system at thermal equilibrium has long been considered impossible. In fact, in the 1960s eminent American physicist Richard Feynman effectively shut down further inquiry ...

Scientists use a bath of swimming bacteria to assemble unconventional materials

A hot bath is a place to relax. For scientists, it is also where molecules or tiny building blocks meet to form materials. Researchers at the Institute of Science and Technology Austria (ISTA) take it to the next level and ...

Polarized imaging of dynamic light scattering to measure nanoparticle size, morphology, and distributions

A team of researchers proposed a fast and convenient method called polarized imaging dynamic light scattering (PIDLS) that quantitively evaluates nanoparticle size, morphology and distribution at the same time. A dimensionless ...
