Résumé

We will introduce the Research Center in Semiconductors’ Technology for Energy, and more particular the activities of my team ‘’Hybrid materials for energy’’. Attaching molecules to surfaces in order to act as probes is a key issue for sensing. Covalent anchoring appears as an attractive route, since it offers the best performances in terms of stability and can be made reproducible and with a high yield. Furthermore, the use of nanostructured substrates allows for an increased surface interaction area and can enhance the detection signal significantly. We will present some examples of these structures. Besides, will present our results on dye sensitized solar cells based on different nanostructures of titanium oxide and conducting polymers.

Biographie

Dr. Sabrina Sam received a Ph.D. in 2010, in physical chemistry of inorganic materials from the University of Science and Technology Houari Boumediene in Algiers, Algeria. She is currently a research director and a group leader (Hybrid materials for energy) at the Research Center in Semiconductors’ Technology for Energy in Algiers, Algeria. Her research interests are in the area of Electrochemical nanostructuration of materials surface (porous silicon, TiO2 nanotubes…), sol-gel and hydrothermal synthesis of nanostructures, surface functionalization (enzymes, peptides, conducting polymers…), and electrodeposition with emphasis on Electrochemical detection of pollutants and energy-related applications.
