Shapeshifting crystals - Varying stability in different forms of gallium selenide monolayers

The gallium selenide monolayer has been recently discovered to have an alternative crystal structure and has diverse potential applications in electronics. Understanding its properties is crucial to understand its functions.

Chemists convert plastic bottle waste into MOF-based insecticide sorbent

Scientists propose a method to create a metal-organic framework sorbent for imidacloprid insecticide removal from water.

High-speed atomic force microscopy takes on intrinsically disordered proteins

Pioneering high-speed atomic force microscope technology has now shed light on the structure and dynamics of some of life's most ubiquitous and inscrutable molecules - intrinsically disordered proteins.

Experiment takes 'snapshots' of light, stops light, uses light to change properties of matter

Researchers performed an ultrafast microscopy experiment, where they trapped green light pulses of 20 fs duration as composite light-electron density fluctuation waves and imaged their propagation on a silver surface at the speed of light.

Quantum nanodevice can be both a heat engine and a fridge at the same time

The device is one of the first to test how quantum effects, which govern the behavior of particles on the smallest scale, might one day be exploited to enhance the performance of nanotechnologies.

A very special (and tiny) Christmas tree

The structure and all details are made of polymer hardened by the scanning of a focused laser beam.

Atomic-scale nanowires can now be produced at scale

Researchers have discovered a way to make self-assembled nanowires of transition metal chalcogenides at scale using chemical vapor deposition. By changing the substrate where the wires form, they can tune how these wires are arranged, from aligned configurations of atomically thin sheets to random networks of bundles.
