Diagnostics of quality of graphene and spatial imaging of reactivity centers on carbon surface

A convenient procedure to visualize defects on graphene layers by mapping the surface of carbon materials with an appropriate contrast agent.

Researchers match physical and virtual atomic friction experiments

By speeding up a real atomic force microscope and slowing down a simulation of one, researchers have conducted the first atomic-scale experiments on friction at overlapping speeds.

Superlubricity gets quantified for the first time

Scientists have not only uncovered the quantitative secret to understanding friction in materials, like graphite, they even invented a way to measure it.

Squeezing light for stronger vibrations

Precise control of interactions between light and vibrating mirrors at the level of single light particles could open a new field of complex quantum physical states.

NNCO to host free webinar for small- and medium-sized nanotechnology businesses

The National Nanotechnology Coordination Office (NNCO) will hold the second in a series of free webinars focusing on the experiences, successes, and challenges for small- and medium-sized nanotechnology businesses and on issues of interest to the nanotechnology business community on Wednesday May 20, 2015 from 2-3pm EDT.

Electrons in graphene corralled using new quantum tool

Researchers have succeeded in creating a new 'whispering gallery' effect for electrons in a sheet of graphene - making it possible to precisely control a region that reflects electrons within the material. They say the accomplishment could provide a basic building block for new kinds of electronic lenses, as well as quantum-based devices that combine electronics and optics.

New graphene nanofiltration application may enable faster, more durable water filters

Engineers have devised a process to repair leaksin graphene, filling cracks and plugging holes using a combination of chemical deposition and polymerization techniques. The team then used a process it developed previously to create tiny, uniform pores in the material, small enough to allow only water to pass through.
