Damage-driven strain localisation in networks of fibres: A computational homogenisation approach

Pablo Antolin Sanchez, Felipe Figueredo Rocha

In many applications, such as textiles, fibreglass, paper and several kinds of biological fibrous tissues, the main load-bearing constituents at the micro-scale are arranged as a fibre network. In these materials, rupture is usually driven by micro-mechani ...

Microstructured biodegradable fibers for advanced controlled release

Shahrzad Shadman Yazdi

Biodegradable polymers are increasingly at the heart of therapeutic devices. Particularly in the form of thin and elongated fibers, they offer an effective strategy for controlled-release in a variety of biomedical configurations such as sutures, scaffolds ...

GarNet++: Improving Fast and Accurate Static 3D Cloth Draping by Curvature Loss

Pascal Fua, Mathieu Salzmann, Victor Constantin, Shaifali Parashar, Erhan Gündogdu

In this paper, we tackle the problem of static 3D cloth draping on virtual human bodies. We introduce a two-stream deep network model that produces a visually plausible draping of a template cloth on virtual 3D bodies by extracting features from both the b ...

Life cycle assessment of bio-based synthetic fibers: the case of polyester substitutes

Tijana Ivanovic

Numerous studies have shown that the textile sector has a high fossil-fuel dependency, emits excessive amount of greenhouse gases and uses vast amount of water. Currently, polyester (fossil-based) makes up about a half of the industry's fiber production an ...

Quantification of Synthetic Polyesters from Biodegradable Mulch Films in Soils

Stephanie Christa Remke

Soil biodegradable mulch films composed of the polyester polybutylene adipate-co-terephthalate (PBAT) are being increasingly used in agriculture. Analytical methods to quantify PBAT in field soils are needed to assess its soil occurrence and fate. Here, we ...

Photocatalytic indoor/outdoor air treatment and bacterial inactivation on CuxO/TiO2 prepared by HiPIMS on polyester cloth under low intensity visible light

Sami Rtimi

In this study, photoactive CuxO/TiO2 coatings were prepared using magnetron sputtering operated at different powers and modes (Direct-current magnetron sputtering and High Power Impulse magnetron sputtering). Indoor/outdoor air pollutions (Volatile Organic ...

Hierarchically Structured Microfibers of ‘Single Stack’ Perylene Bisimide and Quaterthiophene Nanowires

Holger Frauenrath, Roman Niklaus Marty, Ruth Szilluweit, Raffaele Mezzenga

Organic nanowires and microfibers are excellent model systems for charge transport in organic semiconductors under nanoscopic confinement and may be relevant for future nanoelectronic devices. For this purpose, however, the preparation of well-ordered orga ...

Evidence for TiON sputtered surfaces showing accelerated antibacterial activity under simulated solar irradiation

César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi

New evidence is reported for TiON sputtered polyester surfaces activated by sunlight irradiation leading to the accelerated bacterial inactivation in the minute range. The absorption in Kubelka-Munk units of the TiON film was observed to be directly propor ...
