Coffee stains inspire optimal printing technique for electronics

Using an alcohol mixture, researchers modified how ink droplets dry, enabling cheap industrial-scale printing of electronic devices at unprecedented scales.

Spider silk inspires new class of functional synthetic polymers

Scientists developed a new class of polymers based on protein-like materials that work as proton conductors and might be useful in future bio-electronic devices.

New advance in superconductors with 'twist' in rhombohedral graphite

Researchers have revealed a nanomaterial that mirrors the 'magic angle' effect originally found in a complex man-made structure known as twisted bilayer graphene.

Efficient valves for electron spins

Researchers have developed a new concept that uses the electron spin to switch an electrical current. In addition to fundamental research, such spin valves are also the key elements in spintronics.

Cooled graphene mimics effect of enormous magnetic fields that would benefit electronics

Graphene buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum materials and superconductors.

A new way to check the quality of nanosheets

A new way to check nanomaterial quality enters the 'wild frontier' industry.

'Porous liquids' allow for efficient gas separation

Researchers have developed 'porous liquids': Metal-organic frameworks, that are able to separate gas molecules of different sizes from each other, float - finely distributed - in a solvent.

Nanophotonic 3D printing of super-high-resolution displays

The 3D structure in 620nm pixels has an over 50 times higher resolution than that of 8K QLED TV.

Nanocrystals from recycled wood waste make carbon-fiber composites tougher

Researchers use cellulose nanocrystals, to pin and coat carbon nanotubes uniformly onto the carbon-fiber composites. The researchers said their prescribed method is quicker than conventional methods and also allows the designing of carbon-fiber composites from the nanoscale.
