Flexible supercapacitor from stacked nanomaterial

A nanoporous form of graphene made by burning off other elements from an inexpensive polymer has been used to fabricate flexible supercapacitors via a process that can be scaled to industrial quantities to provide energy storage for wearable, flexible electronics.

Targeted nanoparticles deliver molecules to resolve atherosclerotic inflammation

In tests in a mouse model of advanced atherosclerosis, core-shell nanoparticles, composed of block copolymers and targeted to sites of inflammation and vascular injury, delivered a bioactive peptide that improved key properties of advanced plaques.

Small, fast, electrically-driven nanomotors

Bulk nanoscale technologies were used to create three-segment nanowires of gold and nickel, and magnetic bearings of gold, nickel, and chromium. Combinations of DC and AC electric fields were used to assemble nanomotors that can spin at speeds up to 18,000r.p.m., and for up to 15 hours.

Nanotechnology making 3D transistors by directed molecular self-assembly

IBM researchers engineered a class of molecules called block copolymers to self-assemble into dense patterns to extend the capabilities of photolithography.

Mixing two types of nanoparticle triggers structure change

Mixing two different types of cylindrical nanoparticles causes them to reorganize into smaller spherical nanoparticles. A mechanism to release drugs only inside cells that internalize both types?

Penta-graphene a new form of carbon for chemistry and nanotechnology

Computational simulations demonstrate that pentagonal tiling to give a variant of graphene based on pentagons rather than on hexagons is dynamically, thermally, and mechanically stable.

Adding layer to a piezoelectric nanostructure increases output voltage

Applications of nanotechnology to wearable electronics and other portable devices will benefit from the discovery that adding an insulating layer to a piezoelectric nanostructure increases the output voltage by up to 200 times.

Simple nanotechnology modification of alumina surface discourages bacteria

A simple method of producing nanoporous alumina surface discourages bacteria from attaching and forming biofilms, with potential applications in medicine, dentistry, and food processing.

Nearly perfect carbon nanotubes key to energy-saving lights

Painting atomically precise carbon nanotubes onto a cathode produces flat panel lights a hundred times more energy efficient than LEDs.

Grant program to support nanotechnology and other infrastructure

The US National Science Foundation announced a new grant program to develop and apply next-generation networking to advance nanotechnology and other emerging technologies to meet important national needs.
