The realization of active microscale Marangoni surfers

Marangoni surfers are small particles that self-propel while straddling a fluid-fluid interface in a way similar to that in which a surfer moves on the surface of a wave. In recent years, self-propelling particles have become ...

Physicists create turnstile for photons

Physicists from Germany, Denmark, and Austria have succeeded in creating a kind of turnstile for light in glass fibers that allows the light particles to only pass through one at a time

Scientists slow and steer light with resonant nanoantennas

Light is notoriously fast. Its speed is crucial for rapid information exchange, but as light zips through materials, its chances of interacting and exciting atoms and molecules can become very small. If scientists can put ...

Polymers can fine-tune attractions between suspended nanocubes

Colloids are complex mixtures in which microscopic particles of one substance are suspended evenly throughout another. They can be prepared in many different ways, but to achieve desirable properties in the final mixture, ...

Smallest cavity for light realized by graphene plasmons

Miniaturization has enabled technology like smartphones, health watches, medical probes and nano-satellites, all unthinkable a couple decades ago. Just imagine that in the course of 60 years, the transistor has shrunk from ...
