Polymer Structures Serve As 'Nanoreactors' For Producing Nanocrystals With Uniform Sizes, Shapes
2013-06-12 14:09:01

Georgia Institute of Technology Tiny chemistry Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures — including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals. The technique relies on the length of polymer molecules and the ratio of two solvents to control the size and uniformity of colloidal...

Materials researchers at UC Santa Barbara validate decades-old Nobel-Prize-winning theory by developing a simplified lab technique for measuring polymer characteristics using magnets Researchers at UC Santa Barbara have developed a new and highly efficient way to characterize the structure of polymers at the nanoscale — effectively designing a routine analytical tool that could be used by industries that rely on polymer science to innovate new products, from drug delivery gels to...

Potential uses include facial reconstruction for soldiers' blast injuries Biomedical engineers at Johns Hopkins have developed a new liquid material that in early experiments in rats and humans shows promise in restoring damaged soft tissue relatively safely and durably. The material, a composite of biological and synthetic molecules, is injected under the skin, then "set" using light to form a more solid structure, like using cold to set gelatin in a mold. The researchers say the product one...

FINDINGS: Whitehead Institute scientists have created a method that uses the enzyme sortase A to site-specifically modify proteins. Using this technique, researchers were able to increase potency, slow the metabolism, and improve thermal stability of several proteins, including interferon alpha 2 (IFN-alpha 2) and granulocyte colony-stimulating factor 3 (GCSF-3). IFN-alpha 2 is used to treat a variety of diseases, including leukemia, melanoma, and chronic hepatitis C, while GCSF-3 (known as...

HARLEYSVILLE, Pa., Feb. 23, 2011 /PRNewswire/ -- Colorcon, Inc., today announced the expansion of its Nutraficient®, food supplement coating product line to include PVA-based, high-productivity systems designed specifically for use on food supplements marketed within the EU. European Commission Directive (2010/69/EU), already adopted in the UK, allows the use of existing additives in certain food supplement products. The additives now allowed for use include polyvinyl...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
