Light triggers gold nanoparticles in unexpected way

Researchers have discovered a fundamentally different form of light-matter interaction in their experiments with gold nanoparticles.

Quickly capture tiny particles reacting

New method takes a snapshot every millisecond of groups of light-scattering particles, showing what happens during industrially relevant reactions.

Bandage with wearable nanogenerator promotes powerful healing

A new, low-cost wound dressing could dramatically speed up healing in a surprising way. The method leverages energy generated from a patient's own body motions to apply gentle electrical pulses at the site of an injury.

Artificial magnetic field produces exotic behavior in graphene sheets

A new shows that the application of an electrical field to a bilayer graphene system produces an effect identical to that of an extremely intense magnetic field applied to two aligned graphene sheets.

Switching identities: Revolutionary insulator-like material also conducts electricity

Researchers have made a material that can transition from an electricity-transmitting metal to a nonconducting insulating material without changing its atomic structure.

With these nanoparticles, a simple urine test could diagnose bacterial pneumonia

Results could also indicate whether antibiotics have successfully treated the infection.

Potential nanocarrier arthritis treatment prevents cartilage breakdown

Injectable material made of nanoscale particles can deliver arthritis drugs throughout cartilage.

New gold nanoparticle catalyst produces cheap hydrogen

Chemists have discovered cheaper and more efficient materials for producing hydrogen for the storage of renewable energy that could replace current water-splitting catalysts.

Big results from small solutions: new method for analyzing metalloproteins

Metalloproteins (also known as metal-binding proteins) play vital roles in our bodies for oxygen transport and storage, electron transport, oxidation and reduction. A new method only needs a tiny liquid sample to analyze metalloproteins.

Adding graphene to jute fibres could give natural alternative to man-made materials

Scientists have combined graphene with the natural fibre, jute, to create a world?s first for graphene-strengthened natural jute fibre composites.

Researchers remove silicon contamination from graphene to double its performance

A new study identifies silicon contamination as the root cause of disappointing results and details how to produce higher performing, pure graphene.
