    DURHAM, N.C. A new method for attaching a large protective polymer molecule to a protein appears to improve protein drugs significantly. Bioengineers at Duke University developed the new approach and demonstrated in an animal model that the newly created protein-polymer combinations, known as conjugates, remained in circulation significantly longer than an unprotected protein ... To get around this problem, drug makers have been attaching another molecule, a polymer known as polyethyleneglycol... (EurekAlert!)

    Icy Exposure Creates Armored Polymer High-Tech Foams  Aug 20, 2009
    19, 2009) Chemists and engineers at the University of Warwick have found that exposing particular mixtures of polymer particles and other materials to sudden freeze-drying can create a high-tech armored foam that could be used for a number of purposes, including a new range of low power room temperature gas sensors ... However when trying to create particularly strong, stable polymer foam structures engineers and chemists today tend to rely on more complicated processes ... The most... (Science Daily)

    Molecules Wrestle For Supremacy In Creation Of Superstructures  Aug 19, 2009
    9, 2009) Researchers have produced amphiphilic hybrid particles made of a water-insoluble inorganic nanoparticle at the core surrounded by a bristle-like layer of hydrophilic polymer chains. The. (Science Daily)

    Biolubricants Made With Sunflower Oil Just As Efficient As Traditional Ones  Aug 19, 2009
    This work, published in the Environmental Science and Technology journal and titled "Viscosity modification of high-oleic sunflower oil with polymeric additives for the design of new biolubricant formulations," reveals that these vegetal oil components are a clear alternative as a base for lubricants, due to their high biodegradability and low volatility. This project, led by Cr;spulo Gallegos, and another related project from the Spanish Science and Innovation Ministry in collaboration with... (Science Daily)

    Braille Displays Get New Life With Artificial Muscles  Aug 18, 2009
    Bar-Cohen came up with an idea to create a "living Braille," a digital, refreshable Braille device using electroactive polymers, also known as artificial muscles ... Recently, Bar-Cohen was contacted by the Center for Braille Innovation of the Boston-based National Braille Press to reach out to the Electroactive Polymer community and take advantage of his role in this field ... To produce a page of refreshable Braille using electroactive polymers requires individually activating and controlling... (Science Daily)

    UGA, UPR grant license for long-persistence glow materials, in any color  Aug 18, 2009
    They can be used in a multitude of consumer and industrial applications, including signage, special paints, and in combination with polymers for the manufacture of many items, such as color-coded electric wiring, insulation, textiles, novelty-items and printing ink ... Also licensed under the same agreement are methods to customize the wavelength of emitted light, white-emitting phosphors, methods to render hues and tints to emitted light and methods to blend such phosphors with a multitude of...

    New eco-friendly self-cleaning material tough on stains, light on effort  Aug 17, 2009
    "We put out tons of detergents and phosphates each year," said Youngblood, adding that the polymer materials also could reduce the use of detergents for laundering clothes ... "The idea is to use these polymers to clean in situations where it's inconvenient to apply soap or anywhere you would need to have oil cleaned off easily," said Youngblood, a materials engineer at Purdue University in West Lafayette, Ind ... These polymer coatings about 20,000 times thinner than the width of a human hair... (EurekAlert!)

    Camera flash turns an insulating material into a conductor  Aug 13, 2009
    But these techniques could be problematic when graphite oxide is mixed with something else, such as a polymer, because the polymer component may not survive the high-temperature treatment or could block the reducing chemical from reacting with graphite oxide ... When using a light pulse, photothermal heating not only reduces the graphite oxide, it also fuses the insulating polymer with the graphene sheets, resulting in a welded conducting composite.

    New light-emitting biomaterial could improve tumor imaging, study shows  Aug 11, 2009
    A new material developed at the University of Virginia an oxygen nanosensor that couples a light-emitting dye with a biopolymer simplifies the imaging of oxygen-deficient regions of tumors ... The new material is based on poly(lactic acid), a biorenewable, biodegradable polymer that is safe for the body and the environment, and is easy and inexpensive to fabricate in many forms, including films, fibers and nanoparticles ... chemistry professor, synthesized the new material by combining a...
