Stable electrodes for improving printed electronics

April 19, 2012 12:46 pm | News | Comments

In new findings, Georgia Institute of Technology researchers have introduced what appears to be a universal technique to reduce the work function of a conductor. The technique works where they spread a very thin layer of a polymer on the conductor's surface to create a strong surface dipole, which turns air-stable conductors into efficient, low-work function electrodes.

Researchers boost efficiency of multi-hop wireless networks

April 19, 2012 6:50 am | News | Comments

Multi-hop wireless networks can provide data access for large and unconventional spaces, but they have long faced significant limits on the amount of data they can transmit. Now researchers from North Carolina State University have developed a more efficient data transmission approach that can boost the amount of data the networks can transmit by 20% to 80%.

Tumor study reveals size limitations for new drugs

April 10, 2012 9:54 am | by Caroline Perry, Harvard University | News | Comments

Combining two strategies that are designed to improve the results of cancer treatment—angiogenesis inhibitors and nanomedicines—may only be successful if the smallest nanomedicines are used. A new study by researchers at Harvard University and Massachusetts General Hospital has found that normalizing blood vessels within tumors can actually block the delivery of larger nanotherapy molecules.
