Diyne-Functionalized Fullerene Self-Assembly for Thin Film Solid-State Polymerization

Roland Hany, Jakob Heier, Gaëtan Wicht, Raffaele Mezzenga

C-60 fullerene derivatives bearing aliphatic chains can self-assemble into versatile supramolecular structures. Cross-linking of such self-assembled morphologies is an attractive approach to enhance the structural stability of these self-organized structur ...

Universal Behavior in the Mesoscale Properties of Amyloid Fibrils

Paolo De Los Rios, Salvatore Assenza, Raffaele Mezzenga

Amyloid fibrils are ubiquitous proteinaceous aggregates occurring in vivo and in vitro, with an invariant structural fingerprint at the molecular length scale. However, interpretation of their mesoscopic architectures is complicated by diverse observable p ...

Growth and Alignment of Thin Film Organic Single Crystals from Dewetting Patterns

Gian-Luca Bona, Roland Hany, Jakob Heier, Gaëtan Wicht, Raffaele Mezzenga, Thomas Geiger

Studying and understanding the conditions under which organic semiconductors can be engineered to form aligned single crystals in thin films is of primary importance owing to their unique orientation-dependent optoelectronic properties. Efforts to reach th ...

Low-Temperature Preparation of Tailored Carbon Nanostructures in Water

Anna Fontcuberta i Morral, Holger Frauenrath, Vincent Laporte, Bernt Ketterer, Davide Demurtas, Martin Fritzsche, Tobias Hoheisel, Ruth Szilluweit, Raffaele Mezzenga

The development of low-temperature carbonization procedures promises to provide novel nanostructured carbon materials that are of high current interest in materials science and technology. Here, we report a "wet-chemical" carbonization method that utilizes ...

Dewetting-driven hierarchical self-assembly of small semiconducting molecules

Gian-Luca Bona, Roland Hany, Jakob Heier, Raffaele Mezzenga

We describe the self-organization of PCBM and a cyanine dye on chemically patterned surfaces during spin coating from solution. On homogeneous surfaces, a transient bilayer forms, which in a later stage decomposes into PCBM droplets in a matrix of the cyan ...

Understanding amyloid aggregation by statistical analysis of atomic force microscopy images

Giovanni Dietler, Paolo De Los Rios, Jérôme Flakowski, Raffaele Mezzenga

The aggregation of proteins is central to many aspects of daily life, including food processing, blood coagulation, eye cataract formation disease and prion-related neurodegenerative infections[1–5]. However, the physical mechanisms responsible for amyloid ...

Self-assembly of polypeptide/pi-conjugated polymer/polypeptide triblock copolymers in rod-rod-rod and coll-rod-coil conformations

Mohamad Hojeij, Raffaele Mezzenga

Self-assembly in the bulk of a series of hybrid triblock copolymers formed by a poly(9,9-dihexylfluorene-2,7-diyl) (PHF) middle block and two poly(gamma-benzyl-L-glutamate) (PBLG) end blocks has been studied. Since the alpha-helical secondary structure of ...
