Supramolecular Modifications of Semicrystalline Polymers

Supramolecular interactions play an important role in defining the structure and the resulting mechanical properties of materials. For instance, interchain hydrogen-bonding in PAs gives them superior strength and stiffness in engineering materials, while t ...

Inferring the flow properties of epithelial tissues from their geometry

Matthieu Wyart, Marko Popovic, Valentin Camille Druelle

Amorphous materials exhibit complex material properties with strongly nonlinear behaviors. Below a yield stress they behave as plastic solids, while they start to yield above a critical stress sigma(c). A key quantity controlling plasticity which is, howev ...

Laser powder-bed fusion of metallic alloys with enhanced microstructures and properties

Navid Sohrabi

Laser powder-bed fusion (LPBF) is an additive manufacturing (AM) process that uses a laser to selectively melt a powder bed. This process can build dense samples with complicated geometries from a wide variety of metallic alloys. In this thesis, LPBF of al ...

A Photoactivatable Probe for Super-Resolution Imaging of Enzymatic Activity in Live Cells

Pablo Rivera Fuentes, Zacharias Thiel, Nils Trapp

A dual-activatable, fluorogenic probe was developed to sense esterase activity with single-mol. resoln. Without enzymic preactivation, the diazoindanone-based probe has an electron-poor core and, upon irradn., undergoes Wolff rearrangement to give a ring-e ...

Unconventional Tough Double-Network Hydrogels with Rapid Mechanical Recovery, Self-Healing, and Self-Gluing Properties

Paul Joseph Dyson, Zhaofu Fei, Xunhui Wang, Zhangjun Huang, Haiyan Jia

Hydrogels are polymeric materials that have a relatively high capacity for holding water. Recently, a double network (DN) technique was developed to fabricate hydrogels with a toughness comparable to rubber. The mechanical properties of DN hydrogels may be ...

Polymer-theory insights into biomolecular systems

Salvatore Assenza

Boosted by the technological advances in experimental techniques, cellular biology is nowadays facing the need for quantitative approaches in order to rationalize the huge amount of collected data. A particularly succesfull theoretical framework is provide ...

Influences of polymer concrete surfacing and localised load distribution on behaviour up to failure of an orthotropic FRP bridge deck

Thomas Keller, Wendel Michael Sebastian

This paper presents experimental results which demonstrate the important, but to date little-studied influence of surfacing on the response up to failure of orthotropic GFRP bridge decking local to concentrated loading. Four bonded deck specimens were test ...

Low-Stress UV-Curable Hyperbranched Polymer Nanocomposites for High-Precision Devices

Valérie Geiser

The aim of this thesis was to investigate the process-structure-property relationships of UV-curable hyperbranched polymer (HBP)/silica nanocomposites. Special attention was paid to the interplay between photo-conversion, rheological behavior, shrinkage, a ...

Highly filled polymer nanocomposite films derived from novel nanostructured latexes

Riccardo Ruggerone

The overall aim of this thesis has been to assess the potential of latex-based technologies for the preparation of polymer/clay nanocomposites. The key feature of latex-based technologies is that they offer the possibility of improved control of the final ...

Fracture mechanisms in polystyrene/laponite nanocomposites prepared by emulsion polymerization

John Christopher Plummer, Riccardo Ruggerone

Transmission electron microscopy (TEM) has been used to investigate the effect of laponite clay on microdeformation in thin latex-based polystyrene (PS) films, in which the laponite was concentrated at the original interfaces between the PS particles. At r ...
