Journal ArticleDOI
Synthesis and Micrometer-Scale Assembly of Colloidal CdSe/CdS Nanorods Prepared by a Seeded Growth Approach
Luigi Carbone,Concetta Nobile,Milena De Giorgi,Fabio Della Sala,Giovanni Morello,Pierpaolo Pompa,Martin Hÿtch,Etienne Snoeck,Angela Fiore,Isabella R. Franchini,Monica Nadasan,Albert F Silvestre,Letizia Chiodo,Stefan Kudera,Roberto Cingolani,Roman Krahne,Liberato Manna +16 more
TL;DR: A seeded-growth approach is reported to the synthesis of asymmetric core-shell CdSe/CdS nanorods with regular shapes and narrow distributions of rod diameters and lengths, the latter being easily tunable up to 150 nm.
Journal ArticleDOI
Self-energy and excitonic effects in the electronic and optical properties of TiO 2 crystalline phases
Letizia Chiodo,Letizia Chiodo,Juan María García-Lastra,Amilcare Iacomino,Amilcare Iacomino,Stefano Ossicini,Jin Zhao,Hrvoje Petek,Angel Rubio +8 more
TL;DR: In this article, a unified ab initio study of electronic and optical properties of TiO rutile and anatase phases with a combination of density-functional theory and many-body perturbation-theory techniques is presented.
Journal ArticleDOI
Strongly bound excitons in anatase TiO2 single crystals and nanoparticles.
Eduardo Baldini,Letizia Chiodo,Letizia Chiodo,Adriel Dominguez,Maurizia Palummo,Simon Moser,Meghdad Yazdi-Rizi,Gerald Auböck,Benjamin P. P. Mallett,Helmuth Berger,Arnaud Magrez,Christian Bernhard,Marco Grioni,Angel Rubio,Angel Rubio,Majed Chergui +15 more
TL;DR: It is demonstrated that the direct optical gap of single crystals is dominated by a strongly bound exciton rising over the continuum of indirect interband transitions, revealing the existence of strongly boundexcitons in single crystals and nanoparticles.

TL;DR: In this paper, the direct optical gap of single crystals is dominated by a strongly bound exciton rising over the continuum of indirect interband transitions, which possesses an intermediate character between the Wannier-Mott and Frenkel regimes and displays a peculiar two-dimensional wavefunction in the three-dimensional lattice.
Journal ArticleDOI
Hepatitis B protein HBx binds the DLEU2 lncRNA to sustain cccDNA and host cancer-related gene transcription.
Debora Salerno,Letizia Chiodo,Vincenzo Alfano,Oceane Floriot,Grazia Cottone,Alexia Paturel,Matteo Pallocca,M.-L. Plissonnier,S. Jeddari,Laura Belloni,Mirjam B. Zeisel,Massimo Levrero,Francesca Guerrieri +12 more
TL;DR: The ability of HBx to bind RNA to impact on the epigenetic control of both viral cccDNA and host genes is highlighted and provide a new key to understand the role of DLEU2 and EZH2 overexpression in HBV-related HCCs and HBx contribution to hepatocytes transformation.
