- 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...

- Thinner, better, already sold out—the new new thing in solar?
- Solar energy can seem like a green tech fantasy. Energy free for the collection. Found in some of the emptiest spots on earth: deserts, parking lots, urban rooftops, open ocean, airplace wings, at 50,000 feet above the earth. Think about all that sunshine. And a company down...

- 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....

- New oil-repelling material from MIT
- MIT researchers have developed flexible surface coatings that repel oils. According to the research team, this is the first material able to do it. They say that these findings could have applications in aviation, space travel and hazardous waste cleanup. Their oil-repelling, or 'oleophobic' material, is using specially prepared microfibers,...

- 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...

- 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...
