Soft Multimaterial Magnetic Fibers and Textiles

Fabien Sorin, Stella Andréa Françoise Laperrousaz, Hritwick Banerjee, Rémi Andréa La Polla, Andreas Leber, Chaoqun Dong, Syrine Mansour, Xue Wan

Magnetically responsive soft materials are promising building blocks for the next generation of soft robotics, prosthesis, surgical tools, and smart textiles. To date, however, the fabrication of highly integrated magnetic fibers with extreme aspect ratios ...

Renforcement d'un pont à l'effort tranchant par couche de béton – textile

Arnaud Delfino

Le secteur de la construction constitue l’un des domaines les plus polluants de l’activité humaine. Ceci est principalement dû à la très large utilisation du béton, qui demande beaucoup d’énergie lors de la fabrication du clinker. De plus, la quantité de r ...

New Evidence for Ag-Sputtered Materials Inactivating Bacteria by Surface Contact without the Release of Ag Ions: End of a Long Controversy?

Juan Kiwi, Sami Rtimi

The study provides new evidence for Ag-coated polyester (PES) mediating Escherichia colt inactivation by way of genetically engineered E. coli (without porins, from now denoted porinless bacteria). This allows the quantification of the bactericidal kinetic ...

Tensile response of textile reinforced concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Patrick Lorenzo Valeri

Textile Reinforced Concrete (TRC) is a cementitious composite material where a carbon or glass fabric is embedded as reinforcement. The use of TRC allows building thin and light structures, with reduced concrete covers and an enhanced durability due to the ...

Extracellular bacterial inactivation proceeding without Cu-ion release: Drastic effects of the applied plasma energy on the performance of the Cu-polyester (PES) samples

Michaël Bensimon, Sami Rtimi

The widely different effects of Cu-polyester (PES) sputtered by high power impulse magnetron sputtering (HIPIMS) compared to the lower energy direct current magnetron sputtering (DCMS) leading to bacterial inactivation are addressed during the course of th ...

Exploring the use of native spider silk as an optical fibre for chemical sensing

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

A spider uses up to seven different types of silk, all having specific functions, as building material, weapon and sensory organ to detect the presence of preys on its web. Recently, scientists have put under the limelight the extraordinary properties of t ...
