Prototype shows how tiny photodetectors can double their efficiency

New research invokes quantum mechanical processes that occur when two atomically thin materials are stacked together.

A zero-index waveguide

Researchers directly observe infinitely long wavelengths for the first time.

Exploring origin of chiralty in carbon nanotubes

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.

Nanoparticles that stick wounds together

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.

Novel circuit design boosts wearable thermoelectric generators

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.
