Bringing atoms to a standstill

Scientists have miniaturized the optical components required to cool atoms down to a few thousandths of a degree above absolute zero, the first step in employing them on microchips to drive a new generation of super-accurate atomic clocks, enable navigation without GPS, and simulate quantum systems.

Single atoms as a catalyst: Surprising effects ensue

For years, the metal nanoparticles used in catalysts have been getting smaller and smaller. Now, a research team has shown that everything is suddenly different when you arrive at the smallest possible size: a single atom.

Enzyme-powered micromotors based on metal-organic porous materials

Researchers have successfully designed and fabricated bubble-propelled enzymatic micromotors built from a highly porous metal-organic framework (MOF). These new micromotors might lead to applications for drug delivery and adsorption of pollutants.

A new natural platform for realizing flat-band-based quantum phenomena and topological states

Researchers demonstrate that four-layer rhombohedral graphene is a new material for realizing flat-band-based quantum phenomena in a natural way.

Highly functional membrane developed for producing freshwater from seawater

A desalination membrane laminated with nanosheets featuring 2D nanochannels.

Squeezing a rock-star material could make it stable enough for solar cells

A promising lead halide perovskite is great at converting sunlight to electricity, but it breaks down at room temperature. Now scientists have discovered how to stabilize it with pressure from a diamond anvil cell.

A display that completely blocks off counterfeits

Researchers develop nanostructures capable of polarized optical encryption.
