Insights into the fabrication of sub-100 nm textured thermally drawn fibers
Fabien Sorin, Federica Sordo, Inès Richard
The preform-to-fiber thermal drawing process has been recently proposed for the fabrication of fibers and microchannels with submicrometer surface textures. To better control the final architecture and reach small feature size down to tens of nanometers ho ...
AMER INST PHYSICS2019Carbohydrate stabilization extends the kinetic limits of chemical polysaccharide depolymerization
Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Raquel Zambrano Varela
Polysaccharide depolymerization is an essential step for valorizing lignocellulosic biomass. In inexpensive systems such as pure water or dilute acid mixtures, carbohydrate monomer degradation rates exceed hemicellulose—and especially cellulose—depolymeriz ...
2018Towards aerospace grade thin-ply composites: Effect of ply thickness, fibre, matrix and interlayer toughening on strength and damage tolerance
John Botsis, Robin Amacher, Joël Cugnoni, Larissa Sorensen, Sébastien Kohler
Thin-ply composites represent a promising approach to further improve the performance of carbon fibre composite structures thanks to their ability to delay the onset of matrix cracking and delamination up to the point of fibre dominated failure. However, t ...
ELSEVIER SCI LTD2018Cyclic loading of a cellulose/hydrogel composite increases its fracture strength
Dominique Pioletti, Pierre-Etienne Bourban, Peyman Karami, Céline Samira Wyss
The fracture properties of hydrogels which present similar characteristics to the Mullins effect is expected to decrease under repeated cyclic loading. Therefore, we assessed how cyclic loading affects the fracture behavior, the distribution of strain fiel ...
2018Microstructure tailoring of selenium-core multimaterial optoelectronic fibers
Cyril Cayron, Fabien Sorin, Wei Yan, Alexis Gérald Page, Yunpeng Qu, Dang Tùng Nguyen, Tapajyoti Dasgupta
The integration of semiconducting materials within thermally drawn multi-material polymer fibers is emerging as a versatile platform for flexible optoelectronics and advanced fabrics. Developing a deeper control over the microstructure of the electrically ...
Optical Society of America2017Fabrication method of functional micro/nano structures over large-area, flexible and high curvature surfaces, by drawing a fiber from a preform
Fabien Sorin, Wei Yan, Alexis Gérald Page, Yunpeng Qu, Dang Tùng Nguyen
The method for drawing a fiber with a textured surface comprises the following steps: - forming of a preform from which the fiber is to be drawn with a textured surface; - addition of an outer layer to the textured preform to preserve the shape of the text ...
2017Titanium oxide aerogel composites
László Forró, Arnaud Magrez, Endre Horvath
The invention relates to titanium oxide aerogels, in particular to titanium oxide binary or ternary (e.g. titanium oxide-carbon) aerogel monoliths possessing ordered meso- and macroporosity. The porous scaffold can be made with or without addition of binde ...
2016Weaving our way towards a new generation of fibre-optic chemical sensors based on spider silk
Luc Thévenaz, Isabelle Dicaire, Kenny Hey Tow, Desmond Chow Ming Chia
From the spider’s perspective, silk is not only a building material but also a safety net, a weapon and a sensory organ to detect the presence of preys on its web. Indeed, this primeval material has been shaped over hundreds of millions of years by spiders ...
Ieee2016Towards a novel "silky" way to detect chemical species using spider threads
Luc Thévenaz, Isabelle Dicaire, Kenny Hey Tow, Desmond Chow Ming Chia
Silk possesses extraordinary properties that scientists are currently working hard on harnessing. Amongst them, this primeval material has shown early potential of having excellent optical properties. Through a regeneration process, it is possible to obtai ...
2016Ag-surfaces sputtered by DC and pulsed DC-magnetron sputtering effective in bacterial inactivation: Testing and characterization
César Pulgarin, Juan Kiwi, Rosendo Sanjines, Oualid Baghriche
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 ...
