Printable nanogenerator creates electricity from snowfall

Researchers have designed a new device that creates electricity from falling snow. The first of its kind, this device is inexpensive, small, thin and flexible like a sheet of plastic.

Light from exotic particle states

Researchers have developed a new type of light-emitting diode. Light is produced from the radiative decay of exciton complexes in layers of just a few atoms thickness.

Graphene gives a tremendous boost to future terahertz cameras

A new study reports on the development of a graphene-enabled detector for terahertz light that is faster and more sensitive than existing room-temperature technologies.

Novel laser processing method to increase efficiency of optoelectronic devices

Scientists have discovered a new method to passivate defects in next generation optical materials to improve optical quality and enable the miniaturization of light emitting diodes and other optical elements.

3D printing MOFs with nanocellulose

Researchers demonstrate a 3D printable hydrogel ink containing metal-organic frameworks (MOFs). The synthesis and printing processes take place at room temperature using water as a solvent.

Stardust machine fabricates high quantities of complex nanoparticles

At the heart of a new project is the 10 m-long Stardust machine, designed to mimic conditions in the outer atmospheres of red giant stars. In a series of five ultra-high-vacuum chambers, dust grains condense and are tracked on their simulated journey from the star into interstellar space.
