Probing dopant distribution
Berkeley Lab researchers at the Molecular Foundry have shown that when doping a semiconductor to alter its electrical properties, equally important as the amount of dopant is how the dopant is distributed on the surface and throughout the material.

Researchers find the accelerator for molecular machines
How hard can it be to make a wheel rotate in a machine? Very hard actually, when the wheel sits in one of those nano-small molecular machines that are predicted to be running our future machines. But before the molecular machines become part of our daily lives, researchers must be able to control them. A Danish/American research team have now solved part of this problem.

New revolutionary sensor links pressure to color change
A high-resolution pressure sensor developed at the University of California, Riverside indicates pressure by varying its color -- a sensor that all of us can use with just our eyes. This sensor differs from commercially available pressure sensor films. The new technology produces a mosaic of easy-to-distinguish colors and has the benefit of higher contrast and resolution. It can potentially be used in many safety devices for revealing pressure distribution over even very complex surfaces.

Harnessing magnetic vortices for making nanoscale antennas
Scientists seeking ways to synchronize the magnetic spins in nanoscale devices to build tiny yet more powerful signal-generating or receiving antennas and other electronics have published a study showing that stacked nanoscale magnetic vortices separated by an extremely thin layer of copper can be driven to operate in unison. These devices could potentially produce a powerful signal that could be put to work in a new generation of cell phones, computers, and other applications.

A small connection with big implications: Wiring up carbon-based electronics
A good connection between carbon-based materials and external metallic leads is of major importance in nanodevice performance, an aspect where an important step has been surmounted by researchers from UPV/EHU, DIPC and CNRS by studying contacts of carbon nanostructures with atoms of different chemical nature.

New lab-on-a-chip device overcomes miniaturization problems
UNSW Australia chemists have invented a new type of tiny lab-on-a-chip device that could have a diverse range of applications, including to detect toxic gases, fabricate integrated circuits and screen biological molecules. The novel technique developed by the team involves printing a pattern of miniscule droplets of a non-volatile solvent -- an ionic liquid -- onto a gold-coated or glass surface. The results are published in the journal Nature Communications.

Graphene not all good
In a first-of-its-kind study of how a material some think could transform the electronics industry moves in water, researchers at the University of California, Riverside Bourns College of Engineering found graphene oxide nanoparticles are very mobile in lakes or streams and therefore likely to cause negative environmental impacts if released.

Brain tumor cells penetrated by tiny, degradable particles carrying genetic instructions
Working together, Johns Hopkins biomedical engineers and neurosurgeons report that they have created tiny, biodegradable 'nanoparticles' able to carry DNA to brain cancer cells in mice. The team says the results of their proof of principle experiment suggest that such particles loaded with 'death genes' might one day be given to brain cancer patients during neurosurgery to selectively kill off any remaining tumor cells without damaging normal brain tissue.

A glassy look for manganites
Researchers at Berkeley Lab's Advanced Light Source discovered a glass-like re-ordering of electron-spin states as manganite crystals recovered from a photo-excited conductor state back to an insulator state. The discovery holds promise for future ultrafast electronic switching and memory devices.
