Landscapes give latitude to 2-D material designers

Scientists show growing atom-thin sheets on cones allows control of defects.

Engineers pioneer platinum shell formation process - and achieve first-ever observation

Researchers have devised a new method of dynamically forming a platinum shell on a metallic alloy nanoparticle core, a development that may lead to better materials for oxygen reduction reactions in fuel cells that power some cars and electronic devices.

A featherweight, flame-resistant and super-elastic metamaterial

A new featherweight, flame-resistant and super-elastic metamaterial has been shown to combine high strength with electrical conductivity and thermal insulation, suggesting potential applications from buildings to aerospace.

Smart windows that go from clear to dark in under a minute

Engineers have developed dynamic windows that can switch from transparent to opaque or back again in under a minute and do not degrade over time.

Sensing technology takes a quantum leap with photonics research

Funding approved for levitated optomechanics project.

Precisely cutting carbon nanotubes

Scientists demonstrate how multiwalled carbon nanotubes with controllable sizes are cut precisely along the radial direction, and the structural evolution is efficiently investigated through a combination of geometry phase analysis and first-principle calculation.

Assembling nanomachines in bacteria

A new study reveals how a specific structure in flagellum and injectisome, the export gate complex, dynamically assembles and how preventing this assembly could make bacteria innocuous.

Scalable nanowire photonic crystals

Rsearchers demonstrate the bottom-up synthesis of InGaN nanowire photonic crystals with precisely controlled size, spacing, and morphology, which can serve as the fundamental building blocks of a new generation of photonic crystal devices and systems.
