    Ultrafast shock compression waves are launched from a metal ablation layer (cyan) driven by a 1-ns duration laser pulse through a 5-μm layer of polydimethylsiloxane. The shock wave transit time is used to measure the polymer response to very rapid compression. We show that the high strain rate response of PDMS-based polymers is correlated with their static compressibility and that these materials exhibit a liquid-like response even at very high compression rates.

    Based on the variable temperature experiments, the 806 cm−1 band, detected in the FTIR spectra of P3OT and P3DDT films, is assigned to the packing a crystalline phase with the crystallized alkyl side chains. Furthermore, according to the correlation signals of FSLG-HETCOR, it is revealed that in P3BT:PCBM and P3HT:PCBM blends, the crystalline polymers and PCBM are phase separated, while in P3OT:PCBM and P3DDT:PCBM, blend components are mostly miscible.

  3. An insight into molecular motions and phase composition of gliadin/glutenin glycerol blends studied by 13C solid-state and 1H time-domain NMR

    Increasing glycerol content induced different molecular motions in gliadin (Gli)– and glutenin (Glu)–glycerol blends. These motions were related to an increase in the relative amount of protein chains as β-sheets and disordered structures, and a decrease in α-helices. Glycerol was “immobilized” in 10–20% glycerol Gli samples and was found mainly “free” in 30–40% glycerol Gli/Glu samples. Time domain NMR was shown to be a promising technique to monitor the molecular dynamics of proteins and lipids.

    An unexpected signal is found in relationship between temperature and fluorescent intensity measured by a glass fiber taper when the surface of the taper is grafted by PNIPAM. Analysis through differential method shows the collapse of PNIPAM is responsible for the signal. Detailed work on this phenomenon reveals that the signal is caused by the resilient collapse of thermal sensitive PNIPAM chains on the surface of the taper.

  5. Molecular weight dependent structure and charge transport in MAPLE-deposited poly(3-hexylthiophene) thin films

    The structure of MAPLE-deposited P3HT thin films are shown to possess molecular weight (MW) dependence behavior. The MAPLE films deposited from low MW materials are consisted of crystallite domains embedded within highly amorphous environment, whereas those deposited from high MW materials are composed of long polymer chains bridging the aggregate domains. The in-plane mobility is shown to increase with MW, highlighting the importance of domain connectivity in facilitating charge transport in conjugated polymers.
