Laser beams with a 'twist'

Researchers have demonstrated a new type of laser that is able to produce laser beams 'with a twist' as its output. The outputs and superpositions of the new type of laser form a set of beams, called vector vortex beams.

New microwave imaging approach opens a nanoscale view on processes in liquids

Technique can explore technologically and medically important processes that occur at boundaries between liquids and solids, such as in batteries or along cell membranes.

Nanostructures promise big impact on higher-speed, lower-power optical devices

With new technology getting smaller and smaller, requiring lower power, physics research points to new robust electronic technologies using quantum nanowire structures.

Researchers create fundamentally accurate quantum thermometer

Physicists have found a way to calibrate temperature measurements by monitoring the tiny motions of a nanomechanical system that are governed by the often counterintuitive rules of quantum mechanics.

Insect wings inspire antibacterial surfaces for corneal transplants, other medical devices

Someday, cicadas and dragonflies might save your sight. The key to this power lies in their wings, which are coated with a forest of tiny pointed pillars that impale and kill bacterial cells unlucky enough to land on them.

Structure of the new SERS nanotag holds promise for cancer nanotechnology

The discovery of a new nanostructure promises to advance technology used in the early detection and treatment of cancerous cells.

Eggshell nanoparticles could lead to expanded use of bioplastic in packaging materials

Scientists report that adding tiny shards of eggshell to bioplastic could create a first-of-its-kind biodegradable packaging material that bends but does not easily break.
