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 ...
Layered graphene sandwich for next generation electronics
Sandwiching layers of graphene with white graphene could produce designer materials capable of creating high-frequency electronic devices, University of Manchester scientists have found.
Consider the 'anticrystal'
(Phys.org) —For the last century, the concept of crystals has been a mainstay of solid-state physics. Crystals are paragons of order; crystalline materials are defined by the repeating patterns their constituent ...
Carbon-capture breakthrough: Porous material polymerizes carbon dioxide at natural gas wellheads
Rice University scientists have created an Earth-friendly way to separate carbon dioxide from natural gas at wellheads.
Lab study suggests small layer of water, CO2 and silicate lies beneath tectonic plates
Researchers find tin selenide shows promise for efficiently converting waste heat into electrical energy
Researchers lay out theory for metamaterials that act as an analog computer
The field of metamaterials has produced structures with unprecedented abilities, including flat lenses, invisibility cloaks and even optical "metatronic" devices that can manipulate light in the way electronic ...
Mix of graphene nanoribbons, polymer has potential for cars, soda, beer
A discovery at Rice University aims to make vehicles that run on compressed natural gas more practical. It might also prolong the shelf life of bottled beer and soda.
Engineers develop a stretchable, foldable transparent electronic display (w/ Video)
(Phys.org) —Imagine an electronic display nearly as clear as a window, or a curtain that illuminates a room, or a smartphone screen that doubles in size, stretching like rubber. Now imagine all of these ...
Research team develops tattoo-like skin thermometer patch
Raising the IQ of smart windows
Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a new material to make smart windows even smarter. The material is a thin coating of nanocrystals ...
