An international research team reports that light confined in the nanoscale propagates only in specific directions along thin slabs of molybdenum trioxide, a natural anisotropic 2-D material. Besides its unique directional ...
Broadband fiber-optics carry information on pulses of light, at the speed of light, through optical fibers. But the way the light is encoded at one end and processed at the other affects data speeds.
Breakthroughs in the field of nanophotonics—how light behaves on the nanometer scale—have paved the way for the invention of "metamaterials," man-made materials that have enormous applications, from remote nanoscale sensing ...
Rice University nanoscientists have demonstrated a new catalyst that can convert ammonia into hydrogen fuel at ambient pressure using only light energy, mainly due to a plasmonic effect that makes the catalyst more efficient.
Light of different colors travels at different speeds in different materials and structures. This is why we see white light split into its constituent colors after refracting through a prism, a phenomenon called dispersion. ...
An international research group has improved perovskite solar cell efficiency by using materials with better light absorption properties. For the first time, the researchers used silicon nanoparticles. Such nanoparticles ...
One day in the not-so-distant future, light sails may hurtle through space at speeds of around 20% of the speed of light (or 60,000 km/sec), propelled not by fuel but rather by the radiation pressure from high-power lasers ...
Rice University researchers are probing the physical limits of excited electronic states called plasmons by studying them in organic molecules with fewer than 50 atoms.
Researchers have published a review on plasmonic surface lattice resonances, which consist of light absorption by artificial plasmonic materials (metamaterials) based on plasmonic nanostructures.
Rice University nanoscientists have demonstrated a method for loading iron inside nanoparticles to create MRI contrast agents that outperform gadolinium chelates, the mainstay contrast agent that is facing increased scrutiny ...
