Seeing and Touching the Mycomembrane at the Nanoscale

Georg Fantner, John McKinney

Mycobacteria have unique cell envelopes, surface properties and growth dynamics, which all play a part in the ability of these important pathogens to infect, evade host immunity, disseminate and to resist antibiotic challenges. Recent atomic force microsco ...

Static and Fatigue Biaxial Flexural Behavior of Strain-Hardening UHPFRC Thin Slab Elements

Xiujiang Shen

Cast-in-place thin layers of Ultra-High Performance Fiber Reinforced Cementitious Composites (UHPFRC) on the specific zones of existing reinforced concrete (RC) bridge decks has been demonstrated to be a technically efficient and economic rehabilitation an ...

Variational phase-ﬁeld study of adhesive wear: elastic and elastic-plastic models

Sylvain Collet

Wear is well known for causing material loss in a sliding interface. Available macroscopic approaches are bound to empirical ﬁtting parameters. We propose a study of the physical processes that lead to wear at the scale of the surface roughness, where adhe ...
