A novel graphene quantum dot structure takes the cake

In a marriage of quantum science and solid-state physics, researchers at the National Institute of Standards and Technology (NIST) have used magnetic fields to confine groups of electrons to a series of concentric rings within ...

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 ...

Image: Pilanesberg, South Africa

The circular structure dominating this Sentinel-2 image is Pilanesberg, the result of geological activity over more than a billion years. Once a massive volcanic complex towering over 7000 m tall, millions of years of erosion ...

Nano-notch sends self-assembling polymers into a spiral

A simple circular or hexagonal pit written into silicon can be used to generate self-assembling polymer spirals thanks to the addition of a tiny notch in the template, report scientists in the launch issue of Nano Futures.

Device boosts interaction between light and motion

Optomechanical devices, which simultaneously confine light waves and mechanical waves to permit interaction between them, can be used to study fundamental questions in physics and to sense motion similarly to electromechanical ...
