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