Microscopy technique reveals internal structure of reverse osmosis membrane

A novel electron microscopy technique has probed the internal structure of a polyamide membrane used for reverse osmosis at nanoscale resolution.

Polystyrene makes an impact under fire

Polystyrene thin films are twice as good as absorbing impact energy as other leading materials such as graphene.

X-ray studies have revealed that the pathways lithium ions take through a common battery material are more complex than previously thought.

New approach uses hydrogen to overcome hydrogen-embrittlement problem in alloys for applications in extreme conditions.

A new technique can create an individual fingerprint of the current-carrying edge states occurring in topological insulators or 2D materials.

Stress-corrosion cracking can occur when a metal is exposed to tensile stress and corrosion separately, as well as simultaneously.

As much as 100 times more heat than predicted by standard radiation theory can flow between the edges of two very thin semiconductor plates.

Scientists have verified a key prediction from a 55-year-old theory about how electrons move through one-dimensional nanotubes and nanowires.

Precision-synthsized porous graphene is transformed into a semiconductor and the most efficient filter.

Nanoscale diamond needles can bend and deform reversibly, like bristles on a brush, before breaking.

New strategies could translate exceptional attributes of nanoscale fibers like carbon nanotubes and cellulose nanofibrils into macroscale materials.

Scientists have induced a two-dimensional material to cannibalize itself for atomic ‘building blocks’ that go on to form stable structures.

Using computational simulations, scientists have discovered the process by which an iron-based superconductor collapses under pressure.
