The largest particle accelerator in the world has a circumference of around 26 kilometres. Researchers are attempting to go to the other extreme by building the world's smallest machine of this kind - a particle accelerator that fits on a microchip.
Researchers are a step closer to harnessing single pulses of light called solitons, using tiny ring-shaped microresonators, in findings that could aid efforts to develop advanced sensors, high-speed optical communications and research tools.
Researchers study chirality abundances of carbon nanotubes grown on floating liquid gallium droplets, which excludes the influence of catalyst features, and compared them with abundances grown on solid ruthenium nanoparticles.
In spite of medical advances, wound-related complications arising after operations can still be life-threatening. In order to avoid these complications in the future, researchers have developed a new nanoparticle-based tissue glue.
Using flexible conducting polymers and novel circuitry patterns printed on paper, researchers have demonstrated proof-of-concept wearable thermoelectric generators that can harvest energy from body heat to power simple biosensors for measuring heart rate, respiration or other factors.
