Graphene Mode-Locked Ultrafast Laser
Zhipei Sun,Tawfique Hasan,Felice Torrisi,Daniel Popa,G. Privitera,Fengqiu Wang,Francesco Bonaccorso,Denis M. Basko,Andrea C. Ferrari +8 more
TL;DR: The optoelectronic properties of graphene are exploited to realize an ultrafast laser and pave the way to graphene-based photonics.
Journal ArticleDOI
Brownian motion of graphene
Onofrio M. Maragò,Francesco Bonaccorso,Rosalba Saija,G. Privitera,Pietro Giuseppe Gucciardi,Maria Antonia Iatì,Giuseppe Calogero,Philip H. Jones,Ferdinando Borghese,Paolo Denti,Valeria Nicolosi,Andrea C. Ferrari +11 more
TL;DR: In this article, the consequences of the fluctuation-dissipation theorem in two dimensions, by studying the Brownian motion of optically trapped graphene flakes, have been investigated.
Journal ArticleDOI
Solution-phase exfoliation of graphite for ultrafast photonics
Tawfique Hasan,Felice Torrisi,Zhipei Sun,Daniel Popa,Valeria Nicolosi,G. Privitera,Francesco Bonaccorso,Andrea C. Ferrari +7 more
TL;DR: In this paper, the authors exfoliate graphite in both aqueous and non-aqueous environments through mild sonication followed by centrifugation and enrich the dispersions with monolayers.
Journal ArticleDOI
Graphene-Based Interfaces Do Not Alter Target Nerve Cells
Alessandra Fabbro,Alessandra Fabbro,Denis Scaini,Denis Scaini,Verónica León,Ester Vázquez,Giada Cellot,G. Privitera,Lucia Lombardi,Felice Torrisi,Flavia Tomarchio,Francesco Bonaccorso,Francesco Bonaccorso,Susanna Bosi,Andrea C. Ferrari,Laura Ballerini,Laura Ballerini,Maurizio Prato,Maurizio Prato +18 more
TL;DR: Graphene-based substrates (GBSs) are shown to be permissive interfaces, even when uncoated by cell adhesion layers, retaining unaltered neuronal signaling properties, thus being suitable for carbon-based neural prosthetic devices.
Journal ArticleDOI
Density Gradient Ultracentrifugation of Nanotubes: Interplay of Bundling and Surfactants Encapsulation
Francesco Bonaccorso,Tawfique Hasan,Ping-Heng Tan,Calogero Sciascia,G. Privitera,G. Di Marco,Pietro Giuseppe Gucciardi,Andrea C. Ferrari +7 more
TL;DR: Density gradient ultracentrifugation (DGU) has emerged as a promising tool to prepare chirality enriched nanotube samples and the performance of different surfactants for DGU is assessed.
