Beyond batteries: Storing power in a sheet of paper

Researchers at Rensselaer Polytechnic Institute have developed a new energy storage device that easily could be mistaken for a simple sheet of black paper.

The nanoengineered battery is lightweight, ultra thin, completely flexible, and geared toward meeting the trickiest design and energy requirements of tomorrow’s gadgets, implantable medical equipment, and transportation vehicles.

 

Anthrax vaccine produces immunity with nanoparticles, not needles

A vaccine against anthrax that is more effective and easier to administer than the present vaccine has proved highly effective in tests in mice and guinea pigs, report University of Michigan Medical School scientists in the August issue of Infection and Immunity.

The scientists were able to trigger a strong immune response by treating the inside of the animals’ noses with a “nanoemulsion” – a suspension of water, soybean oil, alcohol and surfactant emulsified to create droplets of only 200 to 300 nanometers in size. It would take about 265 of the droplets lined up side by side to equal the width of a human hair.

Computing breakthrough could elevate security to unprecedented levels

By using pulses of light to dramatically accelerate quantum computers, University of Michigan researchers have made strides in technology that could foil national and personal security threats.

It’s a leap, they say, that could lead to tougher protections of information and quicker deciphering of hackers’ encryption codes.

Nanoscale blasting adjusts resistance in magnetic sensors

A new process for adjusting the resistance of semiconductor devices by carpeting a small area of the device with tiny pits, like a yard dug up by demented terriers, may be the key to a new class of magnetic sensors, enabling new, ultra-dense data storage devices. The technique demonstrated by researchers at the National Institute of Standards and Technology (NIST)* allows engineers to tailor the electrical resistance of individual layers in a device without changing any other part of the processing or design.

 

Researchers develop method for mass production of nanogap electrodes

Researchers at the University of Pennsylvania have developed a reliable, reproducible method for parallel fabrication of multiple nanogap electrodes, a development crucial to the creation of mass-produced nanoscale electronics.
