(PhysOrg.com) -- Simple stirring can influence light, according to a report presented in the journal Angewandte Chemie by Kunihiko Okano and co-workers. Dye molecules locked in a gel send out “helical ...

A completely new structure of light just dropped, called the chiral vortex – and the international team of scientists behind its creation says it could be crucial in developing new drugs and in ...

A new laser based on a swirling vortex of light has been created by physicists in the US. The “topological-defect laser” could be a useful addition to lab-on-a-chip devices, where it could manipulate ...

Recently, the Laboratory of Micro and Nano Engineering, School of Engineering Science, University of Science and Technology of China (USTC) has made important progress in the field of structural ...

Smoke rings are being seen in a new light. Doughnut-shaped structures called vortex rings are sometimes seen swirling through fluids. Smokers can form them with their mouths, volcanoes can spit them ...

A complex maze of lasers, lenses and mirrors has been used to twist light into a vortex shaped like a doughnut. Vortex rings are common in fluids – think of smoke rings floating in air or underwater ...
