Des chercheurs intègrent des réseaux de nanocomposites dans les matériaux pour détecter l’apparition des fissures. « Il est impossible de fabriquer un composite sans défauts », déclare Jean-François Feller, enseignant- chercheur responsable du groupe Smart Plastics, à l’IRDL(1). Ces petits défauts favorisent l’apparition de fissures. Il faut donc surveiller leur évolution pour prévenir l’endommagement des [...]

Core-shell nanostructured hybrid composites for volatile organic compound detection. International Journal of Nanomedicine. 2015;10:203-214. doi:10.2147/IJN.S88305.   We report a high-performance chemiresistive sensor for detection of volatile organic compound (VOC) vapors based on core-shell hybridized nanostructures of Fe3O4 magnetic nanoparticles (MNPs) and [...]

PEO-Silane Amphiphiles to Decrease Biofouling on Silicones Prof. Melissa A. Grunlan, Department of Biomedical Engineering, Department of Materials Science & Engineering, Texas A&M University, College Station, TX. http://grunlanlab.tamu.edu Abstract Silicones, particularly silica-reinforced crosslinked polydimethylsiloxane (PDMS), are widely-used for medical, marine and industrial applications. Unfortunately, their extreme hydrophobicity causes poor-antifouling behavior. Although polyethylene oxide (PEO) is known [...]
