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
