Creativity leads to measuring ultrafast, thin photodetector

Making an incredibly fast photodetector is one thing, but actually measuring its speed is another.

Researchers demonstrate tracking of individual catalyst nanoparticles during heating

Researchers have taken atomic-level images of individual nanoparticles during heating that could lead to improved fuel-cell technologies at lower cost, reduce dependence on imported oil and minimize greenhouse gas emissions.

Magnetic nanoparticle chains offer new technique for controlling soft robots

Researchers have developed a technique for using chains of magnetic nanoparticles to manipulate elastic polymers in three dimensions, which could be used to remotely control new soft robots.

Grad students aim to make nanotechnology fun, accessible for kids

Cornell is hoping to bring more 'cool science' to young students in the area with the establishment of CNF Ambassadors, a new program being run by the Cornell NanoScale Science and Technology Facility.

Alternative method for the representation of microstructures in polycrystalline materials

Raman microspectroscopy in an optical microscope provides the means to determine local crystal orientations of polycrystalline materials over large sample areas. This method can be used alternatively to electron backscatter diffraction in a scanning electron microscope.

A microfluidic biochip for blood cell counts at the point-of-care

Researchers have demonstrated a biosensor capable of counting the blood cells electrically using only a drop of blood.

A new process for rapidly fabricating complex 3D nanostructures

The new technique uses nanoelectrospray to provide a continuous supply of liquid precursor, which can include metal ions that are converted to high-purity metal by a focused electron beam.

Nanotech weapon against chronic bacterial infections in hospitals

Researchers develop a new technique that tricks bacterial biofilms into dislodging from their protective matrix, making them vulnerable to treatment with antibiotics.

Real-time tracking shows how batteries degrade

How disposable Lithium batteries degrade during normal use has been tracked in real-time using sophisticated 3D imaging, giving a new way to non-invasively monitor performance loss and guide the development of more effective commercial battery designs.
