Researchers develop technique for imaging individual carbon nanotubes
(Phys.org) —Despite their almost incomprehensibly small size – a diameter about one ten-thousandth the thickness of a human hair – single-walled carbon nanotubes come in a plethora of different "species," each with ...

Long-sought pattern of ancient light detected
(Phys.org) —The journey of light from the very early universe to modern telescopes is long and winding. The ancient light traveled billions of years to reach us, and along the way, its path was distorted by the pull of ...

Wagon-wheel pasta shape for better LED: 'Rotelle' molecules depolarize light more efficiently than 'spaghetti'
One problem in developing more efficient organic LED light bulbs and displays for TVs and phones is that much of the light is polarized in one direction and thus trapped within the light-emitting diode, or LED. University ...

Researchers discover a way to switch liquid crystals off faster
(Phys.org) —A team of physicists at Kent State University has discovered a way to cause liquid crystals to relax to their natural state faster. The result, the team explains in their paper published in Physical Review Letters, ...
'Groovy' hologram creates strange state of light at visible and invisible wavelengths
(Phys.org) —Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated that they can change the intensity, phase, and polarization of light rays using a hologram-like design decorated ...
