Manipulating large numbers of a variety of particles/wires is essential for many lab-on-a-chip technologies. Here we generate a planar array of optofluidic vortices with photothermal gradients from an ...

Researchers have developed a process that can mix tiny volumes of liquid, even in complicated spaces. The discovery of how to mix tiny liquid volumes arose from research directed at improving the ...

Researchers have devised a method for producing toroid-shaped particles through a process called vortex ring freezing. The particles are mass produceable through inexpensive electrospraying. Some of ...

Despite businesses reopening and states relaxing their stay at home restrictions, the threat of COVID-19 still looms large. The biggest risk comes from close person-to-person contact, since the ...

Some of the world's most important discoveries - penicillin, vulcanized rubber and Velcro, to name a few - were made by accident. In fact, it's been said that upward of half of all scientific ...
