Journal ArticleDOI
Growth morphology of nanoscale sputter-deposited Au films on amorphous soft polymeric substrates
TL;DR: In this article, the growth of a room-temperature sputter-deposited thin Au film on two soft polymeric substrates, polystyrene (PS) and poly(methyl methacrylate) (PMMA), from nucleation to formation of a continuous film is investigated by means of atomic force microscopy.
Journal ArticleDOI
Preventing corona effects: multi-phosphonic acid poly(ethylene glycol) copolymers for stable stealth iron oxide nanoparticles
V. Torrisi,Alain Graillot,L. Vitorazi,Q. Crouzet,Giovanni Marletta,C. Loubat,Jean-François Berret +6 more
TL;DR: In this article, a copolymer composition was optimized to provide simple and scalable protocols as well as long-term stability in culture media, and it was shown that polymers with multiple phosphonic acid functionalities and PEG chains outperform other types of coating, including ligands, polyelectrolytes and carboxylic acid functionalized PEG.
Journal ArticleDOI
Chemical effects in C60 irradiation of polymers
TL;DR: In this paper, the C 60 erosion behavior of poly(methyl)methacrylate (PMMA), poly(α-methyl)styrene (PAMS), and polystyrene was studied at various temperatures and compared with that under Ga + irradiation.
Journal ArticleDOI
Metal-Polymer Nanocomposites: (Co-)Evaporation/(Co)Sputtering Approaches and Electrical Properties
V. Torrisi,Francesco Ruffino +1 more
TL;DR: In this article, the basic concepts related to (co-)evaporation and (co)sputtering based fabrication methods and the electrical properties of polymer-metal nanocomposite films are discussed.
Journal ArticleDOI
Supramolecular self-assembled multilayers of terpyridine-functionalized perylene bisimide metal complexes.
Nunzio Tuccitto,I. Delfanti,V. Torrisi,Franco Scandola,Claudio Chiorboli,Vladimir Stepanenko,Frank Würthner,Antonino Licciardello +7 more
TL;DR: Time-resolved spectroscopy measurements seem to indicate that the energy absorbed by the multilayer is promptly dissipated to the gold surface by ultrafast processes.
