New Coating

Materials engineers at Purdue University have created a new type of coating that attracts water yet beads oils, promising potential applications such as "self-cleaning" eyeglasses and antifogging car windshields and ski goggles. The coating consists of a single-molecule-thick layer of a material called polyethylene glycol, where each molecule is tipped with a Teflon-like "functional group" made with fluorine. Water molecules pass through theTeflon-like layer, which acts as a barrier to the larger oil molecules. The water is then attracted to the polyethylene glycol immediately adjacent to the glass surface. Click here for more information.

Tech Needs of the Week

Technical assistance is needed for the manufacture of serrated, scalloped (concave), and wavy (convex) bandknife blades. Of interest are 14 and 16 TPI (teeth per inch) by blanking for the serrated edge. Blanking has been achieved for the scalloped edge, but the resulting shape is not satisfactory. Blanking was not achieved for the wavy edge utilizing the current machine. To respond to this Tech Need, click here. Screen-printing, foil-stamping, or laser-marking methods are needed to engrave permanent markings on stainless steel. The method will be used on both flat surfaces and curvatures. The visibility of the engravings must be clear and prominent. The method will be used on stainless steel dining ware and cups/mugs. To respond to this Tech Need, click here. The Technology Needs of the Week are anonymous requests for technology, distributed through the yet2.com marketplace, that you and your organizationmay be able to fulfill. Responding to a Tech Need is the first step to gaining an introduction with a prospective "buyer" for your technology solution.

Sugar Battery

Researchers at Saint Louis University (St. Louis, MO) have developed a biodegradable fuel cell battery that runs on virtually any sugar source, from soft drinks to tree sap, and has the potential to operate three to four times longer on a single charge than conventional lithium ion batteries. If the battery continues to show promise during further testing and refinement, it could be ready for commercialization in three to five years. “This study shows that renewable fuels can be directly employed in batteries at room temperature to lead to more energy-efficient battery technology than metal-based approaches,” said study leader Shelley Minteer, PhD, an electrochemist at St. Louis University. “It demonstrates that by bridging biology and chemistry, we can build a better battery that's also cleaner for the environment.” For more information, click here.

Technologies of the Week

A low-cost fingerprint detector, using off-the-shelf components integrated into a compact, portable unit, is available. The fingertip is moved relative to a skin-resistance-sensing array to produce a “reference trajectory signal” that is stored in memory. The fingertip is moved again to produce a “sample trajectory signal.” View this technology here. New design criteria have been disclosed that enhance existing security technologies of public key infrastructure and smart cards with the aim to satisfy security needs, such as e-banking and e-health. View this technology here. The Technologies of the Week describe inventions offered for license through the yet2.com marketplace. Search over $2.5 billion of licensable technologies here.

Air Car

Engineers at Moteur Developpment International (MDI, Luxembourg City, Luxembourg) have designed a prototype car that is powered by compressed air. The vehicle has a tubular chassis that is glued together, a fiberglass body, and uses wireless communication between its components. The engine weighs less than half that of a standard car. Ninety cubic meters of air is stored in carbon fiber tanks at high pressure. The expansion of the air stored in the tanks pushes against pistons to create movement. The car is built to integrate with external electronic systems such as voice recognition, Internet connectivity, telephone connectivity, or a GPS. A hybrid model is also under development -- gasoline would be used to run a generator to supply compressed air. It is estimated that one tank of fuel would be enough for a cross-country trip.
