  1. Spatiotemporal Control of Amyloid-Like Aβ Plaque Formation Using a Multichannel Organic Electronic Device

    Erik O. Gabrielsson, Astrid Armgarth, Per Hammarström, K. Peter R. Nilsson and Magnus Berggren

    Article first published online: 5 FEB 2016 | DOI: 10.1002/mame.201500428

    An organic electronic device is used to to kinetically and spatially control Aβ1–40 and Aβ1–42 fibril formation. The formed aggregates show both nanometer-sized fibril structure and microscopic growth, thus mimicking senile plaques. Mechanistically, an initial accumulation of Aβ1–40 is observed, likely driven by electrophoretic migration, which precedes nucleation of amyloid structures in the accumulated peptide cluster.

  2. Enzyme-Mediated In Situ Synthesis and Deposition of Nonaggregated Melanin Protoparticles

    Oliver I. Strube, Anne Büngeler and Wolfgang Bremser

    Article first published online: 5 FEB 2016 | DOI: 10.1002/mame.201500315

    Enzymatic autodeposition of eumelanin is investigated with covalent immobilization of tyrosinase. The resulting melanin particles are rodlike with lengths down to 6 nm and form monolayer structures with film thicknesses of 5–8 nm. Isolated melanin structures of such small size have not been observed before and are possibly a kind of protoparticle in the supramolecular buildup of melanin oligomers.

  3. Synthesis and Properties of Nitrogen-Containing Conjugated Microporous Polymers

    Peng Mu, Hanxue Sun, Zhaoqi Zhu, Weidong Liang, Jiehua Liu and An Li

    Article first published online: 4 FEB 2016 | DOI: 10.1002/mame.201500383

    A series of nitrogen-containing conjugated microporous polymers (NCMPs) with amorphous morphologies is prepared using palladium-catalyzed Sonogashira–Hagihara crosscoupling of 1,3,5-trethynylbenzen with bis(4-bromophenyl) amine in different solvents. The porosity of resulting NCMPs is greatly influenced by the solvents and they show a good performance for CO2 and heavy metal ions adsorption.

  4. Thin Films Bearing Conjugated Polymer Nanoparticles Fabricated by Microliter-Scale Layer-by-Layer Deposition

    Hyunjin Jo, Seung Keun Song, Naraechan Bae, Namsung Cho, Pil J. Yoo, Suk Tai Chang and Juhyun Park

    Article first published online: 3 FEB 2016 | DOI: 10.1002/mame.201500372

    By meniscus-dragging deposition in a layer-by-layer manner, conjugated polymer nanoparticles with surface bromides are conjugated with amine-functionalized dendrimers to build up nanocomposite thin films.

  5. Formation and Distribution of Rubbery Phase in High Impact Poly(propylene) Particles

    Klára Smolná, Tomáš Gregor, Zdeněk Buráň and Juraj Kosek

    Article first published online: 3 FEB 2016 | DOI: 10.1002/mame.201500277

    Thumbnail image of graphical abstract

    Based on the systematical mapping of hiPP morphology by micro-CT and atomic force microscopy, the new concept of rubber incorporation in high impact poly(propylene) particles is introduced. The rubber formation directly on or close to the particle surface is confirmed for the first time here. The effect of homopolymer porosity, rubber content, and antistatic additives on the rubber distribution is discussed.
