A CdS nanowire is used as the gain material and is evanescently coupled to an ?-shaped SiN waveguide at both sides to form...

Mar 30, 2020 (Nanowerk News) Researchers have discovered how two-dimensional cages trap some noble gases. These cages are only nanometers, or billionths of a meter, thick. They can trap atoms of argon, krypton, and xenon at above freezing temperatures. Noble gases are hard to trap using other methods because they...

Home > Press > New mechanism of optical gain in two-dimensional material requires only extremely low input powerTrion optical gain mechanism in electrically gated 2D materials: Exciton produced by a pump laser combined to form a trion. A weak probe light bounces off the trion gets amplified by emitting a...

Mar 30, 2020 (Nanowerk News) The brain is one of our most vulnerable organs, as soft as the softest tofu. Brain implants, on the other hand, are typically made from metal and other rigid materials that over time can cause inflammation and the buildup of scar tissue. MIT engineers are...

Mar 27, 2020 (Nanowerk News) Cornell University astronomers have created five models representing key points from our planet's evolution, like chemical snapshots through Earth's own geologic epochs. The models will be spectral templates for astronomers to use in the approaching new era of powerful telescopes, and in the hunt for...

Mar 25, 2020 (Nanowerk News) Spilled coffee forms a ring as the liquid evaporates, depositing solids along the edge of the puddle. This "coffee ring effect" has fascinated scientists for decades, but now a team says they have uncovered the mechanism behind an even more striking, web-like pattern that forms...

"For All...

Mar 24, 2020 (Nanowerk News) Graphene-based biosensors could usher in an era of liquid biopsy, detecting DNA cancer markers circulating in a patient’s blood or serum. But current designs need a lot of DNA. In a new study, crumpling graphene makes it more than ten thousand times more sensitive to...
