Flexible polymer opals
A synthetic material which mimics the brightest and most vivid colours in nature, and changes colour when twisted or stretched, has been developed by researchers at the University of Cambridge, and could have important ...
Cradle turns smartphone into handheld biosensor
(Phys.org) —Researchers and physicians in the field could soon run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones.
Manipulating Lorentz and Fano spectral line shapes
Optics innovation an industry success
An optics innovation by a University of Sydney researcher has been a financial and technology transfer success story creating a wave of sales for Finisar, the Australian company that has used the new technology.
Palaeontologist reveals insects' colourful past
(Phys.org)—An international research team led by a University of Bristol scientist has explained the preservation of colours in fossil insects for the first time.
Soft Lego built in the computer
Barbara Capone of the Computational Physics Group of the University of Vienna has developed a new method for the construction of building blocks at the nanoscale. The researcher in Soft Matter Physics, who ...
New approach using nanoparticle alloys allows heat to be focused or reflected just like electromagnetic waves
An MIT researcher has developed a technique that provides a new way of manipulating heat, allowing it to be controlled much as light waves can be manipulated by lenses and mirrors.
Physicists take photonic topological insulators to the next level
Researchers at The University of Texas at Austin have designed a simulation that for the first time emulates key properties of electronic topological insulators.
Photons emitted by quantum dots can be made indistinguishable through quantum frequency conversion
(Phys.org)—An international collaboration led by researchers from the NIST Center for Nanoscale Science and Technology has demonstrated the ability to make photons emitted by quantum dots at different frequencies identical to each other by shifting t ...
Long-wavelength laser will be able to take medicine fingerprints
A laser capable of working in the terahertz range – that of long-wavelength light from the far infrared to 1 millimetre – enables the 'fingerprint' of, say, a drug to be examined better than can be done ...
Taming mavericks: Researchers use synthetic magnetism to control light
(Phys.org)—Stanford researchers in physics and engineering have demonstrated a device that produces a synthetic magnetism to exert virtual force on photons similar to the effect of magnets on electrons. The advance could ...
Fish skin structure explains biological cloaking
The highly effective optical means by which silvery fish, such as the European sardine and Atlantic herring, camouflage themselves from predators is explained this month in Nature Photonics.
Researchers glimpse the inside of a photonic crystal
Scientists shed light on glowing materials
Researchers at King's College London, in collaboration with European research institutes ICFO (Barcelona) and AMOLF (Amsterdam), have succeeded in mapping how light behaves in complex photonic materials inspired by nature, ...
