Optical surface states in magnetophotonic crystals

Scientists working at the University of Navarra in Spain say they have developed a more efficient laser crystal.

(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. “Thi ...

Photonic crystals, with highly periodic structures that can be designed to control light, have the potential to revolutionize everything from computing to communications. But researchers need more effective and affordable ...

Researchers at North Carolina State University have successfully engineered liquid crystals that contain very high concentrations of metals – potentially paving the way toward the creation of “magnetic ...

(PhysOrg.com) -- With its complete lack of atoms, a vacuum is often considered to be the best known insulator. For this reason, vacuums are regularly used to reduce heat transfer, such as in the lining of ...

When you flip a light switch, a steady stream of photons is emitted by millions of atoms inside a light bulb. All atoms emit light at random instants in time, just like rain drops ticking on a roof. A team of ...

An international team of scientists using a new X-ray method recorded the internal structure and cell movement inside a living frog embryo in greater detail than ever before.

Spinning-disk confocal microscopy is an optical imaging technique that can be used to generate detailed three-dimensional fluorescence images of living cells and their contents. Although a powerful tool for ...

Most cells exist in a hydrated state and often live suspended in solution. In order to be imaged, cells must generally be frozen or dried, and then stained with substances such as heavy metals. Unfortunately, ...

Andong He saw a phenomenon at work in his breakfast bowl that he couldn't explain. It prompted this question: How does cereal shape influence the way cereals floating in the milk join?

(Phys.org) —Physicists may have created the smallest drops of liquid ever made in the lab. That possibility has been raised by the results of a recent experiment conducted by Vanderbilt physicist Julia Velkovska and her ...

A new window into the nature of the universe may be possible with a device proposed by scientists at the University of Nevada, Reno and Stanford University that would detect elusive gravity waves from the ...
