New 'gold standard' for flexible electronics

Simple, economical process makes large-diameter, high-performance, thin, transparent, and conductive foils for bendable LEDs and more.

Atomic magnet curve balls

A twisted array of atomic magnets were driven to move in a curved path, a needed level of control for use in future memory devices.

Targeting neurons with nanoparticles

A research team has elucidated the mechanisms through which nanoparticles modulate bioelectric activity from single neuron to neuronal networks.

Use of machine learning to design optimal nanostructures to control heat current in materials

Scientists have developed a calculation method for identifying optimal nanostructures to either maximize or minimize the thermal resistance of target materials. This method reduced the amount of calculation by more than 90% compared to conventional methods.

Nanoparticles as food additives: improving risk assessment

The anticaking agent E551 silicon dioxide, or silica, has been used widely in the food industry over the past 50 years, and was long thought to be quite safe. Now, however, researchers have discovered that these nanoparticles can affect the immune system of the digestive tract.

Symposium explores possibilities of origami nanomachines

Origami usually brings to mind folded paper cranes, but scientists see in origami the promise of nanoscale machinery.

Scientists create a cellular guillotine for studying single-cell wound repair

In an effort to understand how single cells heal, mechanical engineers have developed a microscopic guillotine that efficiently cuts cells in two. Learning more about single-cell wound repair could lead to self-healing materials and machines.
