Many colours from a single dot

Physicists Bart van Dam and Katerina Newell (Dohnalova) from the UvA Institute of Physics, in collaboration with Emanuele Marino and Peter Schall as well as colleagues from the University of Twente and Jiljin University in ...

Researchers invent light-emitting nanoantennas

Scientists from ITMO University have developed effective nanoscale light sources based on halide perovskite. Such nanosources are based on subwavelength nanoparticles serving both as emitters and nanoantennas and allow enhancing ...

Researchers create first superatomic 2-D semiconductor

Atoms are the basic building blocks of all matter—at least, that is the conventional picture. In a new study, researchers have fabricated the first superatomic 2-D semiconductor, a material whose basic units aren't atoms ...

Squeezing into the best shape

Until now, producing liquids that can be shaped and reshaped on demand hasn't been possible. Scientists discovered a simple way to form stabilized droplets in a variety of structures. Tightly packed nanoparticle-polymer assemblies ...

Scientists observe nanowires as they grow

At DESY's X-ray source PETRA III, scientists have followed the growth of tiny wires of gallium arsenide live. Their observations reveal exact details of the growth process responsible for the evolving shape and crystal structure ...

First 3-D imaging of excited quantum dots

Quantum dots are rapidly taking center stage in emerging applications and research developments, from enhanced LCD TVs and thin-film solar cells, to high-speed data transfer and fluorescent labeling in biomedical applications.

Liquid crystal molecules form nano rings

At DESY's X-ray source PETRA III, scientists have investigated an intriguing form of self-assembly in liquid crystals: When the liquid crystals are filled into cylindrical nanopores and heated, their molecules form ordered ...
