AMADEus Seminar - Dr. Marco Faustini - Monday 21 november 2016 - 2:00 pm ICMCB (Amphi)

Abstract: “Soft-chemistry” approaches (based on self-assembly, sol-gel chemistry, coordination chemistry...) allows periodical assembly the matter at the sub 100 nm scales into nanostructured materials with a great control in term of dimensionality, periodicity and composition. Complex patterns at the micro/nanometric scale can also be achieved by all the so-called “soft-lithography” approaches that consist in molding the material through an elastomeric stamp.

In this talk I will describe our initiative in integrating functional nanoporous materials (MOFs and mesoporous sol-gel materials and films) into real devices by combining soft-chemistry and soft-lithography. The goal is to rationally combine the original properties of nanoporous materials (composition, high porosity, sorption selectivity, capillary condensation…) and of the periodic structures (light and liquid confinement, diffraction, guiding...) to achieve new multifunctional platforms for fundamental studies and real applications.¹ Applications of these systems in photonics and nanofluidics will be presented.

Porous photonic sensing platforms (1D, 2D photonic crystals, graded materials,² diffraction gratings) were developed for the easy-detection of toxic compounds by using a simple and accessible tool such as the camera of a smart phone that can be potentially interfaced with image analysis applications for real-time air-quality monitoring.^3,4

Sol-gel based nanopillared and nanowired micro and nanofluidic channels were also fabricated to induce and study chemical reactions (nanoparticles formation or air-liquid biphasic reactions) in nanoconfined environments.^5,6 Finally, the hierarchically patterned coatings were used as platform to induce controlled condensation of femtoliter dew droplets in which the droplet shape could be dynamically varied in space and in time. Based on these results an example of open, out-of-equilibrium nanofluidic system will be proposed.

SHORT CV

Dr. Marco Faustini received his Master degree in 2008 at the University of Trento (Italy) after having worked for one year at the Helsinki University of Technology on protective sol-gel coatings for architecture. In 2011, he obtained his PhD working at Laboratoie Chimie de la Matière Condensée (LCMCP) on the fabrication of magnetic data storage devices by bottom-up approaches. He pursuit his research as post-doc at the Center of Applied Microfluidic Chemistry in POSTECH, South Korea, where he worked on the integration of functional nanostructured materials in microfluidic devices. In 2012 he moved back to France as assistant professor at the University Pierre Marie Curie where he joined the "Nanomaterials and Hybrid Materials" group at the LCMCP. His main research activities concern the synthesis and processing of nanostructured materials for photonics, nanofluidics, sensing, and lithography. He authored around 40 articles and 5 patents.
