Invisibility cloaks closer thanks to 'digital metamaterials'
The concept of "digital metamaterials" – a simple way of designing metamaterials with bizarre optical properties that could hasten the development of devices such as invisibility cloaks and superlenses – is reported in a paper published today in Nature ...
Graphene gets a 'cousin' in the shape of germanene
A team of European researchers has become one of the first groups to successfully synthesize the 2D material germanene.
'Nano-pixels' promise thin, flexible, high resolution displays
A new discovery will make it possible to create pixels just a few hundred nanometres across that could pave the way for extremely high-resolution and low-energy thin, flexible displays for applications such ...
Researchers create nanoparticle thin films that self-assemble in one minute
The days of self-assembling nanoparticles taking hours to form a film over a microscopic-sized wafer are over. Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory ...
Researchers uncover secret of eumelanin pigment's ability to absorb a broad spectrum of light
Melanin—and specifically, the form called eumelanin—is the primary pigment that gives humans the coloring of their skin, hair, and eyes. It protects the body from the hazards of ultraviolet and other ...
Rare earth ions in a crystal become candidate for a quantum memory
(Phys.org) —A promising material is lining itself up as a candidate for a quantum memory. A team at the Max Planck Institute for the Science of Light in Erlangen is the first to succeed in performing high-resolution ...
Probing dopant distribution: Study opens door to better doping of semiconductor nanocrystals
(Phys.org) —The icing on the cake for semiconductor nanocrystals that provide a non-damped optoelectronic effect may exist as a layer of tin that segregates near the surface.
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," ...
