Science - Research results from University of Michigan update understanding of science

  2010 MAR 22 - (VerticalNews.com) -- "Chain-grafted Au nanoparticles were synthesized and incorporated into a fluorescent polymer, poly[2-methoxy-5-(2-ethythexyloxy)-1,4-phenylenevinylene] (MEH-PPV), host," scientists in the United States report.

  "We show that control of the Au nanoparticle distribution within MEH-PPV is achieved by Manipulating the enthalpic and entropic interactions between the grafted brush layers and the host chains, Further. we show that the fluorescence of these Au/MEH-PPV nanocomposite thin films may be ''tailored'' by as Much as an order of magnitude through changes in the nanoparticle distribution, brush length, and nanoparticle size," wrote X.C. Chen and colleagues, University of Michigan ...read more


Science - Researchers from University of Vigo report recent findings in science

  2010 MAR 22 - (VerticalNews.com) -- "The fibrillation process of the islet amyloid polypeptide (IAPP) and its fragment (IAPP((20-29))) was studied by means of Thioflavin T (ThT) fluorescence and transmission electron microscopy in the absence and presence of N-isopropylacrylamide:N-tert-butylacrylamide (NiPAM:BAM) copolymeric nanoparticles. The process was found to be strongly affected by the presence of the nanoparticles, which retard protein fibrillation its a function of the chemical surface properties of the nanoparticles," scientists writing in the journal Langmuir report ...read more


Science - Recent studies from Singapore National University add new data to science

  2010 MAR 22 - (VerticalNews.com) -- According to a study from Singapore, Singapore, "The self-assembly of the binary molecular system comprising copper(II) phthalocyanine (CuPC) and copper-hexadecafluoro-phthalocyanine (F16CuPC) on graphite has been investigated by in situ low-temperature scanning tunneling microscopy (LT-STM). The adsorption of this binary molecular system on graphite results in the formation of a well-ordered chessboardlike nanopattern. ...read more
