Nanotechnology-based flexible actuators

In 'Nanotube paper flexes on demand,' nanotechweb.org reports that French researchers are using multiwalled carbon nanotubes MWCNTs reinforced with polyvinyl alcohol PVA to develop ultra-lightweight actuators for aerospace applications. The scientists have developed a paper-like sheet which bends when the material is electrically stimulated. As said one of the lead...

Beijing Olympic logos written by nano pens

Northwestern University NU researchers have used a new printing technique, called Polymer Pen Lithography PPL, to print 15,000 Beijing Olympic logos on one square centimeter. Besides this 'marketing' approach, the PPL technique is very innovative. It can write on three different length scales -- nanometer, micrometer and millimeter -- using...

Generating electricity with polymers?

After yesterday, here is another story about using plastics as a power source. Researchers at the University of Pittsburgh are using ionic polymers immersed in a river to generate 'clean' electricity for the city of Vandergrift, Pennsylvania. If the project is successful, the city's downtown 'could one day get 20...

Can nerves really regenerate?

People suffering of injury to the brain or spinal cord cannot currently be treated because central nervous system neurons have a very limited capability of self-repair and regeneration. But now, researchers from the Georgia Institute of Technology have developed a potentially promising strategy for encouraging the regeneration of damaged neurons....

Plastic to help water and gas industries

Researchers have lots of imagination. After developing plastic as solid as steel, other scientists from in Australia, Korea and in the U.S. have created a plastic which could cut CO2 emissions and purify water. Their new material mimics pores found in plants and is exceptionally efficient. As said one of...

A plastic as solid as steel

A new composite plastic built layer by layer has been created by engineers at the University of Michigan. This plastic is as strong as steel. It has been built the same way as mother-of-pearl, and shows similar strength. Interestingly, this 300-layer plastic has been built with 'strong' nanosheets of clay...

Toward safer gene therapy?

Gene therapy has been used in more than 1,000 clinical trials during the last 20 years. But the U.S. Food and Drug Administration FDA has never approved a single application. The reason is simple: the former trials were using viruses to deliver genes to fight diseases like cancer. And viruses...

Wrinkles in nanoscale-sized films

An international team of scientists from Chile, the Netherlands and the U.S. has found a very simple way to measure the material properties of thin films having a thickness of only a dozen nanometers. The researchers just dropped water on thin film floating in a Petri dish. This causes wrinkles...

A very robust 50-atom-thick nanosheet

A team of U.S. scientists has discovered that by tightly packing molecules, they could obtain nanothin sheets of materials showing surprising strength. As one enthusiast researcher says, "It's an amazing little marvel." The team adds that "even when suspended over a tiny hole and poked with an ultrafine tip, the...

Polymer opal films are not for rings

British and German researchers have developed a new type of flexible plastic film. These 'polymer opal films' can change colors under certain conditions. For example, they could easily help you to see if some kind of perishable food items are not good anymore because the packaging would change color. They...

Flexible transistors for your clothes

Physicists from Austria and the U.S. have built ultra-thin pressure sensors which can be woven into sensitive textiles. In "Haute couture from the experimental physics lab," they say that their new thin-film transistors TFTs can switch back and forth in reaction to pressure. To achieve this effect, they coupled TFTs...

Plastic batteries coming soon?

Engineers at Brown University have built a prototype of an hybrid plastic battery that uses a conductive polymer. The system, which marries the power of a capacitor with the storage capacity of a battery, can store and deliver power efficiently. For example, during performance testing, "it delivered more than 100...

Repairing genetic mutations with lasers?

German researchers at the Christian-Albrechts-Universität zu Kiel CAU think they've proved that genetic information can be controlled by light. The group studied the interaction between the four DNA bases -- adenine A, cytosine C, guanine G, and thymine T -- by using femtosecond time-resolved fluorescence spectroscopy. The researchers think that...
