Structural Study of Four-Armed Amphiphilic Star-Block Copolymers: Pristine and End-Linked Tetronic T1307

Mortensen, Kell; Annaka, Masahiko

We present a comparative structural study of 30 wt % aqueous suspensions of two related systems based on 4-arm PEO–PPO type of macromolecules (Tetronic T1307, BASF) with the PPO block near the star center. One system concerns the pristine 4-arm PEO–PPO star block copolymer T1307. The second system is a…

Improving Visible-Light Transparency of Drawn Melt-Crystallized Linear Polyethylenes: Influence of Molecular Weight Distribution

Shen, Lihua; Severn, John; Bastiaansen, Cees W. M.

A series of drawn melt-crystallized linear polyethylenes (LPEs) with different molecular weight distributions (MWD = Mw/Mn) ranging from 2 to 25 are investigated with respect to the visible-light transparency. The results indicate that the MWD of the LPEs significantly influences the visible-light transparency of drawn melt-crystallized LPEs. At a high…

Functionalized Mesoporous Silica via an Aminosilane Surfactant Ion Exchange Reaction: Controlled Scaffold Design and Nitric Oxide Release

Soto, Robert J.; Yang, Lei; Schoenfisch, Mark H.

, Nitric oxide-releasing mesoporous silica nanoparticles (MSNs) were prepared using an aminosilane-template surfactant ion exchange reaction. Initially, bare silica particles were synthesized under basic conditions in the presence of cetyltrimethylammonium bromide (CTAB). These particles were functionalized with nitric oxide (NO) donor precursors (i.e., secondary amines) via the addition of…

Morphology of Fe nanolayers with Pt overlayers on low-temperature annealing

Gong, J.; Paul, N.; Nagy, B.; Dolgos, M.; Bottyán, L.; Müller-Buschbaum, P.; Böni, P.; Zheng, J.-G.; Paul, A.

Agglomeration or dewetting is technologically important in the microelectronics industry as it is one of the methods of producing arrays of nanosized metal clusters. This report investigates the grain morphology evolution due to low-temperature annealing (473 K) in Fe layers with Pt overlayers. X-ray diffuse scattering and grazing-incidence small-angle X-ray scattering…

Deformation mechanisms in ionic liquid spun cellulose fibers

Wanasekara, Nandula D.; Michud, Anne; Zhu, Chenchen; Rahatekar, Sameer; Sixta, Herbert; Eichhorn, Stephen J.

The molecular deformation and crystal orientation of a range of next generation regenerated cellulose fibers, produced from an ionic liquid solvent spinning system, are correlated with macroscopic fiber properties. Fibers are drawn at the spinning stage to increase both molecular and crystal orientation in order to achieve a high tensile…

On the dissolution state of cellulose in cold alkali solutions

Hagman, Joel; Gentile, Luigi; Jessen, Christian Moestrup; Behrens, Manja; Bergqvist, Karl-Erik; Olsson, Ulf

We have characterized the dissolved state of microcrystalline cellulose (MCC) in cold alkali solutions using a combination of small angle X-ray (SAXS) and static light scattering (SLS), 11^1H NMR, NMR self-diffusion, and rheology experiments. NMR and SAXS data demonstrate that the cellulose is fully molecularly dissolved. SLS, however, shows the…

Extended Law of Corresponding States Applied to Solvent Isotope Effect on a Globular Protein

Bucciarelli, Saskia; Mahmoudi, Najet; Casal-Dujat, Lucía; Jéhannin, Marie; Jud, Corinne; Stradner, Anna

Investigating proteins with techniques such as NMR or neutron scattering frequently requires the partial or complete substitution of D₂O for H₂O as a solvent, often tacitly assuming that such a solvent substitution does not significantly alter the properties of the protein. Here, we report a systematic investigation of the solvent…
