Synthetic chemists today have the ability to construct molecules of almost any atomic composition, creating new materials with any number of promising applications that range from sustainable energy and environmental remediation, to high-performance electronics.
Fluid jets are all around us: from inkjet printing, to the “Old Faithful” geyser in Yellowstone National Park, to cosmological jets several thousand light years long.
Researchers at the University of Rochester have measured for the first time light emitted by photoluminescence from a nanodiamond levitating in free space. In a paper published this week in Optics Letters, they describe how they used a laser to trap nanodiamonds in space, and – using another laser – caused the diamonds to emit light at given frequencies.
Bending light beams to your whim sounds like a job for a wizard or an a complex array of bulky mirrors, lenses and prisms, but a few tiny liquid bubbles may be all that is necessary to open the doors for next-generation, high-speed circuits and displays, according to Penn State researchers.
A new, high-precision 3D printer can create nanometer-sized objects and is way faster than similar devices.
Researchers at California's Stanford University have built and demonstrated an ultrafast nanoscale light-emitting diode (LED) that consumes significantly less power than current laser-based systems.
