Researchers have discovered a new self-assembly method for producing defect-free graphene nanoribbons with periodic zigzag-edge regions. In this bottom-up technique, researchers use a copper substrate's unique properties to change the way the precursor molecules react to one another as they assemble into graphene nanoribbons.
To help laser systems overcome loss, operators often pump the system with an overabundance of photons, or light packets, to achieve optical gain. But now engineers have shown a new way to reverse or eliminate such loss by, ironically, adding loss to a laser system to actually reap energy gains. In other words, they've invented a way to win by losing.
Particle physicists have a hard time identifying all the elementary particles created in their particle accelerators. But now researchers have designed a material that makes it much easier to distinguish the particles. The material manipulates the Cherenkov radiation from particles with high momentum so that they get a distinct light cone angle.
Scientists have demonstrated, for the first time, a new type of mirror that forgoes a familiar shiny metallic surface and instead reflects infrared light by using an unusual magnetic property of a non-metallic metamaterial.
UT Arlington engineering professors have received a $451,781 Air Force Office of Scientific Research grant to examine the material surface at the micro- and nano-scale level that will provide clues for predicting fatigue in aircraft parts.
Researchers have developed a novel yet simple technique, called 'diffusion driven layer-by-layer assembly', to construct graphene into porous three-dimensional (3D) structures for applications in devices such as batteries and supercapacitors.
Nanomedicines consisting of nanoparticles for targeted drug delivery to specific tissues and cells offer new solutions for cancer diagnosis and therapy. Understanding the interdependency of physiochemical properties of nanomedicines, in correlation to their biological responses and functions, is crucial for their further development of as cancer-fighters.
