Shining potential of missing atoms      (via sciencedaily.com)     Original source 

Single photons have applications in quantum computation, information networks, and sensors, and these can be emitted by defects in the atomically thin insulator hexagonal boron nitride (hBN). Missing nitrogen atoms have been suggested to be the atomic structure responsible for this activity, but it is difficult to controllably remove them. A team has now shown that single atoms can be kicked out using a scanning transmission electron microscope under ultra-high vacuum.

Source-shifting metastructures composed of only one resin for location camouflaging      (via sciencedaily.com)     Original source 

Acoustic source-shifters make observers mis-perceive the location of sound by reproducing a sound emanating from a location different from the actual location of a sound source. Researchers have now developed a design approach to produce high-performance source-shifters using a common polymer for location camouflage. Utilizing inverse design based on topology optimization, this development could pave the way for advanced augmented reality and holography technology.
