Scientists created dye-based molecules that self-assemble into ring-shaped structures, mimicking nature's light-harvesting systems. These stacked rings allow electrons and energy to circulate freely, ...

Mathematicians call the shape of a doughnut a 'toroid'. Physicists call a swirling fluid a 'vortex'. A toroidal vortex, then, is a swirling doughnut of fluid. This video from the Sleek Geeks archive ...

This paper by TSAW Drones discusses the need for less noise in UAVs, how these toroidals can benefit the drone industry, how these propellers came to be and how exactly they reduce the noise. Also, in ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Recently, a major breakthrough in the field of optical toroidal vortices has been achieved and published in ...

1. Fill a tall glass to the brim with water and wait for at least 30 seconds. Even though it looks still, water keeps swirling for ages so the longer you wait the better. HINT: Use an eye-dropper if ...

Humans do it with smoke. With a little snort, dolphins can produce a nearly perfect "air" rings, (sophisticated non-dolphins called them toroidal vortices) which they turn into underwater toys. If ...

When you need a toroid the easiest source is often to wind it yourself. The problem being that placing a few hundred windings around a ferrite ring is a real drag, especially if you have to make ...
