  • imes are changing, swiftly, and the way we keep time is too. The U.S. military will soon have greener devices on their wrist, with Hewlett-Packards current development. These wrist-watches by HP will boast flexible display screens that will show up a load of information besides the time, including maps and strategic information to aide soldiers in combat. The watch, known as the Dick Tracy will use a plastic screen. Soaking in the sun will help power up the watch and have it ticking. The prototype of the watch will be up and functioning in a year by HP. For starters, the U.S. military will use the Dick Tracy (named after the comic-strip detective with his awesome wristwatch) on a small group of soldiers first, who are bound to enjoy the technology, before spreading out to the entire force. The flexible plastic display, unlike the usual glass ones is also unbreakable, and can withstand the shocks of a battle field. Dick Tracy is yet another green addition for the U.S. military, this time in the form of wrist-watches

Stratasys, the leading supplier of rapid prototyping equipment by volume, is now teaming up Ultem 9085 polether imide with new machines designed for direct digital manufacturing, which is the production of parts directly from CAD files. EOS is now offering PEEK (polyetheretherketone) polymer from Victrex for its laser sintering systems. Other manufacturers, such as Z Corp. and 3D Systems, are developing stronger proprietary materials. Ultem extends the digital manufacturing process into the aircraft market in a major way. Until now, Ultem 9085 was only available for use in conventional processing methods, such as injection molding, which require expensive tooling. Manufacturing using equipment originally developed for rapid prototyping creates opportunities for design engineers to make parts even more complex than is possible with injection molds. The cost of the materials coupled with processing time, however, will limit adoption, at least for now to low-volume parts

  • A team of researchers at the FOM institute AMOLF (The Netherlands) has succeeded for the first time in powering an energy transfer between nano-electromagnets with the magnetic field of light. This breakthrough is of major importance in the quest for magnetic 'meta-materials' with which light rays can be deflected in every possible direction. This could make it possible to produce perfect lenses, and in the fullness of time, even 'invisibility cloaks.'

    "pzt-rubber A new material developed by researchers at Princeton and Caltech is capable of harvesting energy from the simplest of movements like walking or breathing. This new rubber chip made of PZT (lead zirconate titanate) nanoribbons could eventually power small portable electronic devices like cell phones. The PZT is embedded in silicone rubber sheets that produce electricity when flexed or other pressure is applied. The scientists who developed the chip see them being inserted into shoes or even within the body to continually harness power for our portable devices. Before that freaks you out too much, the scientists envision the chips being placed next to the lungs to utilize breathing motions for powering pacemakers. Pacemaker users wouldn't have to undergo surgery to replace batteries since their breathing would be a constant source of energy. The reason this particular material stands out compared to all of the other piezoelectric materials out there is that it's far more efficient. According to the researchers, PZT can convert 80 percent of mechanical energy applied to it into electric energy, which is 100 times more efficient than quartz. That efficiency allows it to harness such small movements like breathing and opens up a much greater range of possibilities for its use."

Self-Contained Solar Power System is Only 9mm - 1 views

  • Researchers at the University of Michigan have unveiled their latest breakthrough:  a tiny solar power system that contains a processor, battery and solar cells all in 9 cubic millimeters! The miniature system measures 2.5 by 3.5 by 1 millimeters -- 1,000 times smaller than any comparable commercial system.  It's extremely energy efficient and the scientists say that it could almost operate perpetually if the battery didn't have to be replaced after many years. The system uses an ARM processor, a popular, widely-used processor which will make commercial adoption of this technology much easier. The system could be remodeled to generate power from movement or heat instead of light, making it fit for a variety of uses.  Like the small, flexible kinetic-energy harvester we profiled a last month, the scientists also see this device serving as a power source for medical implants like pacemakers.  Other possibilities include powering environmental sensors that track air and water quality and motion sensors for buildings, homes and bridges. The good news is that the researchers are already working on commercially developing the system.  With a host of possible applications, who knows where this itty bitty power generator might end up.

  • In an important first for a promising new technology, scientists have used a quantum computer to calculate the precise energy of molecular hydrogen. This groundbreaking approach to molecular simulations could have profound implications not just for quantum chemistry, but also for a range of fields from cryptography to materials science. "One of the most important problems for many theoretical chemists is how to execute exact simulations of chemical systems," says author Alán Aspuru-Guzik, assistant professor of chemistry and chemical biology at Harvard University. "This is the first time that a quantum computer has been built to provide these precise calculations."

  • This is the discovery that could put the College of Wooster on the map: glass that swells like a sponge.  Put together like a nano-matrix, the new glass can unfold to hold up to eight times its weight.  The glass binds with gasoline and other pollutants containing volatile organic compounds but it does not bind with water, so it acts like a “smart” sponge, capable of picking and choosing from contaminated groundwater.

  • The ultra-high-strength composite metal foam created by Afsaneh Rabiei is a highlight of a well-traveled career during which the researcher has tried to learn everything she can about advanced materials. The result: a brand new material that can save energy and lives. “Basically, it is a new material for all sorts of safety devices,” said Rabiei, associate professor of mechanical and aerospace engineering at North Carolina State University. Rabiei’s invention isn’t the first metal foam, but she says it’s the strongest. The main weakness of existing metal foams is the varying sizes of their cells — tiny pockets of space inside the material. Instead, Rabiei used cells of standard sizes and combined them with a metallic matrix to support the cell walls. That helps
  • And since the bulk steel is three times heavier than the steel foam, it’s easy to see how the foam could attract car manufacturers looking for a bumper that will improve safety and gas mileage. Rabiei sees plenty of uses for her invention, including in airplanes, boats, and structures that need impact protection with maintaining low weight. It’s this high strength-to-density ratio — defining a material that’s both strong and light — that makes Rabiei’s foam unique. “This material showed a much higher strength-to-density ratio than any metal foam that has ever been reported,” she said.

  • Graphene could someday replace silicon as a semiconductor material and make our chips smaller and faster, except for one tiny detail: it’s been rather hard to mess with its electronic properties. Until now. “We have experimentally realized and theoretically investigated, for the first time, perfect atomic wires in graphene,” Ivan Oleynik, one of the two University of South Florida professors behind the discovery, told Wired.com. Atomic wires are short chains of atoms that conduct electricity and so far, they have been hard to achieve in graphene.
