Intercalation of cellulase enzyme into a hydrotalcite layer structure

Zou, N.; Plank, J.

A new inorganic–organic hybrid material whereby cellulase enzyme is incorporated into a hydrotalcite type layered double hydroxide (LDH) structure is reported. The Mg2Al–cellulase–LDH was synthesized via co-precipitation from Mg/Al nitrate at pH=9.6. Characterization was performed using X-ray powder diffraction (XRD), small angle X-ray scattering (SAXS), elemental analysis, infrared spectroscopy…

Potential Determining Salts in Microemulsions: Interfacial Distribution and Effect on the Phase Behavior

Johans, Christoffer; Behrens, Manja A.; Bergquist, Karl Erik; Olsson, Ulf; Manzanares, José A.

In this work we consider potential determining salts, also referred to as phase transfer agents for a future objective of electrochemistry at the oil?water interface in microemulsions. We have studied these salts, composed of a hydrophilic and a hydrophobic ion, in microemulsion stabilized by nonionic surfactants with an oligo ethylene…

Superparamagnetic regular nanopillar-like structures studied by grazing-incidence X-ray scattering: effect of vertical correlation

Paul, Amitesh; Paul, Neelima; Müller-Buschbaum, Peter; Bauer, Andreas; Böni, Peter

Grazing-incidence small-angle X-ray scattering is reported from nanoclusters in superparamagnetic (SPM) polycrystalline Co separated by Au. The self-organization of the Co nanoclusters is in the form of nanopillar-like structures with high perpendicular magnetic anisotropy. A distinct signature of regular near-neighbour ordering is observed, which is commonly observed in patterned nanostructures.…

Reduced Phase Separation and Slowing of Dynamics in Polyurethanes with Three-Dimensional POSS-Based Cross-Linking Moieties

Raftopoulos, Konstantinos N.; Koutsoumpis, Stefanos; Jancia, Małgorzata; Lewicki, James P.; Kyriakos, Konstantinos; Mason, Harris E.; Harley, Stephen J.; Hebda, Edyta; Papadakis, Christine M.; Pielichowski, Krzysztof; Pissis, Polycarpos

Octa-OH-functional POSS has been incorporated into a model polyurethane elastomer as a comparatively massive and notionally ?robust? 3-dimensional cross-linking core. The effects of this cross-linking moiety on the morphology and molecular dynamics of the system are studied over a range of size and time scales. Microscopy, scattering, spectroscopic, thermal, and…

A new crystallization process in polypropylene highly filled with calcium carbonate

Schawe, Jürgen E. K.; Vermeulen, Paul A.; Drongelen, Martin van

The influence of high amounts of calcium carbonate filler on the crystallization behavior of polypropylene (PP) is investigated by differential scanning calorimetry (DSC) and fast scanning DSC measurements. The non-isothermal crystallization process at industrially relevant cooling rates of about 100 K/s is significantly influenced by the calcium carbonate filler. Isothermal…

Nematic Ordering of SWNT in Meso-Structured Thin Liquid Films of Polystyrenesulfonate

Itzhak-Cohen, Racheli; Nativ-Roth, Einat; Levi-Kalisman, Yael; Josef, Elinor; Szleifer, Igal; Yerushalmi-Rozen, Rachel

The formation of nematic-like islands of single-walled carbon nanotubes (SWNT) in polystyrenesulfonate (PSS) dispersions confined into nanometrically thin films is reported. The SWNT are observed to assemble into orientationally ordered phases, where the intertube distance, as measured via transmission electron microscopy at cryogenic temperatures, matches the polyelectrolyte?s bulk correlation…

The effect of dendrimer generations on the structure of Q G LLC mesophase and drug release

Bitan-Cherbakovsky, Liron; Aserin, Abraham; Garti, Nissim

In this paper the cosolubilization of 2nd, 3rd, and 4th generations of polypropyleneimine (PPI: PPI-G2, -G3, and -G4) dendrimers with sodium diclofenac (Na-DFC) into reverse gyroid cubic (QG) liquid crystals is reported. Structural properties and interactions of PPI dendrimers with and without the drug were studied using small-angle X-ray scattering,…

Effect of biotechnologically modified alginates on LDH structures

Sieber, Volker; Plank, Johann; Sperl, Nadine; Schmid, Jochen; de Reese, Johanna

Four alginates possessing different guluronic/mannuronic acid ratios and one acetylated alginate were investigated with respect to their behaviour during intercalation into layered double hydroxides (LDHs). Two alginates were commercial products while the others were synthesised by way of bacterial fermentation and in one sample followed by enzymatic treatment. Intercalation was…

Self-organization of Fe clusters on mesoporous TiO2 templates

Ziegler, Patrick; Paul, Neelima; Müller-Buschbaum, Peter; Wiedemann, Birgit; Kreuzpaintner, Wolfgang; Jutimoosik, Jaru; Yimnirun, Rattikorn; Setzer, Annette; Esquinazi, Pablo; Böni, Peter; Paul, Amitesh

Fe layers with thicknesses between 5 and 100 nm were sputtered on mesoporous nanostructured anatase TiO2 templates. The morphology of these hybrid films was probed with grazing-incidence small-angle X-ray scattering and X-ray reflectivity, complemented with magnetic measurements. Three different stages of growth were found, which are characterized by different correlation…

Formation of liquid crystalline phases in aqueous suspensions of platelet-like tripalmitin nanoparticles

Schmiele, Martin; Gehrer, Simone; Westermann, Martin; Steiniger, Frank; Unruh, Tobias

Suspensions of platelet-like shaped tripalmitin nanocrystals stabilized by the pure lecithin DLPC and the lecithin blend S100, respectively, have been studied by small-angle x-ray scattering (SAXS) and optical observation of their birefringence at different tripalmitin (PPP) concentrations φ PPP . It could be demonstrated that the platelets of these potential…
