Magnesium (Mg) and its alloys degrade under physiological conditions, which makes them interesting implant materials especially for osteosynthesis and cardiovascular applications. But how strong is the connection between the implant, the corrosion layer and the surrounding tissue, namely bone? Biomechanical approaches like push-out tests have shown that a degraded Mg-pin is surprisingly well...
Supramolecular polymers, in which noncovalent interactions, like hydrogen bonds, keep the repeating units together, offer exciting prospects for materials with novel properties because the interactions are reversible. This is the case of diaminotriazine (DAT) and thymine-1-acetic acid (THY) (one of the nucleobases in DNA functional groups) that form heteromolecular interactions, and...
Foams are a complex material with a rich structural hierarchy. Aqueous foams in particular change their structure over time due to processes like gravitational drainage, Ostwald ripening and coalescence. Because of this complex structure, modelling SANS curves obtained from foams is challenging. Here, a newly developed model, describing SANS data of foams, is presented. The model takes into...
Ionic assembly of biopolyelectrolytes with oppositely charged polyelectrolytes or surfactants allows to construct self-assembled colloidal systems, which are very versatile with respect to their structures and properties, such as rheology or solubilisation. This is very important for many practical applications of colloidal formulations, but increasingly requires high biocompatibility of the...
