Fabricating 3D Photonic Crystals

(PhysOrg.com) -- “In photonic crystals, the ability to control the structure of a material in full three dimensional space, allows you to control the way that light flows through it,” John Rogers tells PhysOrg.com. “This ...

Robot NICO learning self awareness using mirrors

(Phys.org)—Self awareness is one of the hallmarks of intelligence. We as human beings clearly understand that we are both our bodies and our minds and that others perceive us in ways differently than we perceive ourselves. ...

Topology can play a crucial role in the generation of laser light

A donut is not a bun. From a mathematical point of view, they are two fundamentally different objects: The donut has a hole, the bun does not. A circle inside the donut around its hole in the center cannot be shrunk to a ...

New sensor detects ever smaller nanoparticles

Conventional microscopes produce enlarged images of small structures or objects with the help of light. Nanoparticles, however, are so small that they hardly absorb or scatter light and, hence, remain invisible. Optical resonators ...

Oysters produce 3-D structures organised by physical processes

Scientists from the University of Granada (UGR) have discovered that oysters are capable of producing three-dimensional structures organized by physical (colloidal) processes—the result of which resembles a solid foam—by ...

Mind and space bending physics on a convenient chip

Thanks to Einstein, we know that our three-dimensional space is warped and curved. And in curved space, normal ideas of geometry and straight lines break down, creating a chance to explore an unfamiliar landscape governed ...

After 90 years, scientists reveal the structure of benzene

One of the fundamental mysteries of chemistry has been solved by a collaboration between Exciton Science, UNSW and CSIRO – and the result may have implications for future designs of solar cells, organic light-emitting diodes ...
