Structure-function relationships in Macadamia integrifolia seed coats – fundamentals of the hierarchical microstructure

Schüler, Paul ; Speck, Thomas ; Bührig-Polaczek, Andreas ; Fleck, Claudia (2014-08-07)

The shells/coats of nuts and seeds are often very hard to crack. This is particularly the case with Macadamia seed coats, known to exhibit astoundingly high strength and toughness. We performed an extensive materials science characterization of the complex hierarchical structure of these coats, using light and scanning electron microscopy in 2D as well as microCT for 3D characterization. We dif...

Structure and molecular dynamics of thin films of homopolymers and miscible polymer blends

Madkour, Sherif A. (2018)

In recent years, research on nanoscale confinement of polymers has witnessed topical investigations in attempt to tune polymer properties on demand. One of the most studied forms of nanoconfinement are thin films, where 1D confinement results from the reduction of the film thickness. For these systems, it is crucial to understand how confinement affects the glass transition phenomenon and the a...

Characterization and mechanical properties investigation of the cellulose/gypsum composite

Nindiyasari, Fitriana ; Griesshaber, Erika ; Zimmermann, Tanja ; Manian, Avinash Pradip ; Randow, Clemens ; Zehbe, Rolf ; Fernandez-Diaz, Lurdes ; Ziegler, Andreas ; Fleck, Claudia ; Schmahl, Wolfgang W. (2016)

We synthesized cellulose/gypsum composites in the presence and absence of sodium alginate and investigated the interaction between the composite components as well as the mechanical properties of the final composites. Four different types of cellulose fiber materials were used: cellulose UFC100, cellulose B400, nanofibrillated cellulose, and Lyocell fiber. For all investigated composites the to...
