Imagine a clock that doesn’t have electricity, but its hands and gears spin on their own for all eternity. In a new study, physicists at the University of Colorado Boulder have used liquid crystals, ...

What have you missed on Hackaday this week? Elliot Williams and Al Williams compare notes on their favorites from the week, and you are invited. The guys may have said too much about the Supercon ...

Physicists used liquid crystals to build a near-perpetual clock-like system, demonstrating a 'time crystal' phase where components move continuously without external power. (Nanowerk News) Imagine a ...

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 ...

Since more than a decade it has been possible for physicists to accurately measure the location of individual atoms to a precision of smaller than one thousandth of a millimeter using a special type ...

An atom is the smallest unit of an element that retains its chemical properties. It is made of protons, neutrons, and electrons. (Image: M ...

(Nanowerk Spotlight) At the scale of individual atoms, materials behave in ways that defy everyday intuition. Stretch a metal wire by a few micrometers and its resistance changes only slightly.
