Moisture-responsive graphene 'robots' crawl with no external power source

Created using only a camera flash and graphene oxide, smart materials move in response to changes in humidity.

Neuron-integrated nanotubes to repair nerve fibers

A new study sheds light on the properties of nanostructures capable of ensuring an effective integration with nerve cells, an essential quality for developing innovative systems targeting the repair of neuronal damages.

Researchers present a new method of 3D-plasmon tomography

In new work, researchers could show for the first time how the third dimension can be reconstructed completely in the framework of a tomographic imaging process by rotating the sample and processing a series of tilted two-dimensional projections.

How to train your drugs: from nanotherapeutics to nanobots (w/video)

Nanotechnology is creating new opportunities for fighting disease - from delivering drugs in smart packaging to nanobots powered by the world?s tiniest engines.

From 1D polymers to 2D polymers

Scientists report a facile, highly efficient, and versatile strategy for preparation of free-standing single-monomer-thick 2D polymers in water without any aid.

Novel nanocellulose hydrogel suitable for 3D printing

Researchers have developed a nanocellulose-alginate hydrogel suitable for 3D printing. The composition of the hydrogel was optimized based on material characterization methods and 3D printing experiments.

Topoligical insulator research accelerates quest for quicker, longer-lasting electronics

Researchers report they have created a TI film just 25 atoms thick that adheres to an insulating magnetic film, creating a heterostructure. This heterostructure makes TI surfaces magnetic at room temperatures and higher, to above 400 Kelvin or more than 720 degrees Fahrenheit.
