A levitated nanosphere as an ultra-sensitive sensor

Researchers have demonstrated how to remove from and add elementary charges to a nanosphere that can be used for measuring extremely weak forces.

Ruthenium atoms on graphene to match platinum standard for fuel cells

Scientists have fabricated a durable catalyst for high-performance fuel cells by attaching single ruthenium atoms to graphene.

Lab-made synapses for artificial intelligence

Scientists have developed an artificial synapse capable of simulating a fundamental function of our nervous system - the release of inhibitory and stimulatory signals from the same 'pre-synaptic' terminal.

Extremely small gas and pressure sensors made from 'white graphene'

Researchers have found a way to create and clean tiny mechanical sensors in a scalable manner. They created these sensors by suspending a two-dimensional sheet of hexagonal boron nitride over small holes in a silicon substrate.

Nanofabrication: A slick route to smart surfaces

Controlled rupturing of thin films can make low-cost nanopatterned arrays for solar cells and biomolecular detection.

Nanostructured silicon - Bristling with potential

Better understanding the principles of silicon etching leads to improved surface patterning.

Nanoparticles improve the strength of metallic alloys

Superalloys are the wonder materials of metallurgy. By fine-tuning their composition, scientists can increase mechanical strength and improve resistance to corrosion and high-temperature shape changes.
