More efficient risk assessment for nanomaterials

Nanotechnology is booming, but risk assessment for these tiny particles is a laborious process that presents significant challenges to the German Federal Institute for Risk Assessment (BfR). To find more efficient test methods, ...

A novel cellular process to engulf nano-sized materials

Nanometers are one billionth of a meter, a metric typically used to measure molecules and scientific building blocks not visible to the human eye. Materials of tens and/or several hundred nanometers in diameter have unique ...

Tiny light box opens new doors into the nanoworld

Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and linking light to matter at the nano level. Using a tiny box, built from stacked atomically thin material, ...

Scientists discover a new class of single-atom nanozymes

Nanozymes—catalytic nanomaterials with enzyme-like characteristics—offer the advantage of low cost, high stability, tunable catalytic activity and ease of mass production. For these reasons, they have been widely applied ...

No ink needed for these graphene artworks

When you read about electrifying art, "electrifying" isn't usually a verb. But an artist working with a Rice University lab is in fact making artwork that can deliver a jolt.

When a defect might be beneficial

In the quest to design more efficient solar cells and light-emitting diodes (LEDs), a team of engineers has analyzed different types of defects in the semiconductor material that enables such devices to determine if and how ...

Detecting light in a different dimension

Scientists from the Center for Functional Nanomaterials (CFN)—a U.S. Department of Energy (DOE) Office of Science User Facility at Brookhaven National Laboratory—have dramatically improved the response of graphene to ...
