Researchers combined a sub-wavelength nanowire with a photonic crystal platform, and demonstrated 2 firsts: Continuous-wave lasing oscillation by sub-wavelength nanowire, as well as high-speed signal modulation by a nanowire laser.
The value of the surface tension of water at room temperature is known accurately to four significant figures and is recommended as a standard for the calibration of other devices. New research now shows that this value is not as universal as previously believed.
Researchers have developed a new method to create films of porous metal-organic frameworks fully aligned on inorganic substrates. The method is simple, requiring only that the substrate and an organic linker are mixed under mild conditions, and fast, producing perfectly aligned films within minutes.
