Effect of mechanical damage and wound healing on the viscoelastic properties of stems of flax cultivars (Linum usitatissimum L. cv. Eden and cv. Drakkar)

Véronique Michaud, Sara Dalle Vacche, Federica Sordo

As plant fibres are increasingly used in technical textiles and their composites, underlying principles of wound healing in living plant fibres are relevant to product quality, and provide inspiration for biomimetic healing in synthetic materials. In this ...

Self-Replenishing, Wear-Resistant and Anti-Sticking Surfaces Based on Liquid Impregnation of Microstructured Mesoporous α-AI₂O₃ [Alpha Alumina] Matrices

Sriharitha Rowthu

Fabrication of wear-resistant omniphobic surfaces is a persistent scientific challenge and essential for various applications such as in paint industries, fluid transport, antifouling, reduction of friction drag on ship hulls, and stain resistant textiles. ...

Towards a new generation of fibre-optic chemical sensors based on spider silk threads

Luc Thévenaz, Kenny Hey Tow, Isabelle Dicaire, Desmond Chow Ming Chia

A spider uses up to seven different types of silk, all having specific functions, to build its web. For scientists, native silk - directly extracted from spiders - is a tough, biodegradable and biocompatible thread used mainly for tissue engineering and te ...

Spider silk: a novel optical fibre for biochemical sensing

Luc Thévenaz, Kenny Hey Tow, Isabelle Dicaire, Desmond Chow Ming Chia

Whilst being thoroughly used in the textile industry and biomedical sector, silk has not yet been exploited for fibre optics-based sensing although silk fibres directly obtained from spiders can guide light and have shown early promises to being sensitive ...

Effect of annealing and silylation on the strength of melt-spun Ni-Mn-Ga fibres and their adhesion to epoxy

Véronique Michaud, Yves Leterrier, Susanne Glock, Edgars Sparnins

Single crystals of ferromagnetic Ni-Mn-Ga shape memory alloys show magnetic-field and stress induced twinning, leading to shape memory. Adaptive composites can thus be produced by embedding single crystalline particles or bamboo-structured Ni-Mn-Ga fibres ...

Comparison of HIPIMS sputtered Ag- and Cu-surfaces leading to accelerated bacterial inactivation in the dark

César Pulgarin, Juan Kiwi, Sami Rtimi

Recently, compact uniform and adhesive films of Ag and Cu have been prepared by DC-magnetron sputtering (DC), pulsed DC magnetron sputtering (DCP) and high power impulse magnetron sputtering (HIPIMS). This study reports the HIPIMS deposition for Ag and Cu ...

Ag-surfaces sputtered by DC and pulsed DC-magnetron sputtering effective in bacterial inactivation: Testing and characterization

César Pulgarin, Juan Kiwi, Rosendo Sanjines, Cristina del Socorro Lonfat

This study addresses the deposition of active, uniform nanoparticulate Ag-thin films on polyester textiles by DC-magnetron sputtering (DC) and pulsed DC-magnetron sputtering (DCP). The deposition of Ag on the polyester fiber was observed to be the function ...

Assessment of semi-impregnated fabrics in honeycomb sandwich structures

Jan-Anders Edvin Maansson, Véronique Michaud

Semi-impregnated fabrics, or semipregs, are fabrics alternating dry and resin impregnated areas along the fibre bed surface. Due to their increased initial through thickness permeability to gas flow, these could constitute an alternative to prepreg in the ...

Magnetron-Sputtered Ag Surfaces. New Evidence for the Nature of the Ag Ions Intervening in Bacterial Inactivation

César Pulgarin, Juan Kiwi, Rosendo Sanjines

DC-magnetron sputtering with an Ag target on textile surfaces produced Ag particles with sizes similar to 4.7 nm (+/- 15%). Sputtering for 15 s led to Ag layers of 15-20 nm. The threshold sputtering time precluding airborne bacterial growth was about 60 s. ...
