Researchers fabricate the world's smallest QR code that, invisible to the naked eye, encrypts information to only be visible by an infrared camera lens.
The first self-powered programmable metasurfaces for wireless communications harvest ambient energy, adaptively tuning signals without external power cords.
Researchers have introduced a new method for in vivo brain imaging, enabling large-scale and long-term observation of neuronal structures and activities in awake mice.
Scientists compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions with the environment. Correlation spectroscopy can be used to increase the precision of sensor networks.
Inspired by nature, nanotechnology researchers have identified 'spontaneous curvature' as the key factor determining how ultra-thin, artificial materials can transform into useful tubes, twists and helices.
