Ferritins are ubiquitous and conserved proteins endowed with enzymatic ferroxidase activity, that oxidize Fe(II) ions at the dimetal ferroxidase centre to form a mineralized Fe(III) oxide core deposited within the apo-protein shell. Herein, the in vi

Nano Letters, 2017, 17 (3), pp.1899-1905. ⟨10.1021/acs.nanolett.6b05208⟩

The magnetic properties of some single molecule magnets (SMM) on surfaces can be strongly modified by the molecular packing in nanometric films/aggregates or by interactions with the substrate, which affect the molecular orientation and geometry. Det

Core-Hole Screening, Electronic Structure, and Paramagnetic Character in Thin Films of Organic Radicals Deposited on SiO2/Si(111)

Autor: Sabine-Antonia Savu, Lorenzo Sorace, Maria Benedetta Casu, Reza Kakavandi, Donella Rovai, Matteo Mannini

Publikováno v: The Journal of Physical Chemistry C. 118:8044-8049

We investigate thin films of a pyrene derivative of the nitronyl nitroxide radical deposited on SiO2/Si(111). By using X-ray photoelectron spectroscopy and near-edge X-ray absorption fine structure spectroscopy, we study the electronic structure of t

Molecular Order in Buried Layers of TbPc2 Single-Molecule Magnets Detected by Torque Magnetometry

Autor: Donella Rovai, Mauro Perfetti, Matteo Mannini, Philippe Sainctavit, Lorenzo Poggini, Roberta Sessoli, Michele Serri, Sandrine Heutz

Publikováno v: Advanced materials (Deerfield Beach, Fla.). 28(32)

Cantilever torque magnetometry is used to elucidate the orientation of magnetic molecules in thin films. The technique allows depth-resolved investigations by intercalating a layer of anisotropic magnetic molecules in a film of its isotropic analogue

We present the results of an X-ray magnetic circular dichroism investigation of a reduced version of Mn 12 benzoate. At variance with the parent Mn 12 benzoate compound, which, analogously to Mn 12 acetate, has a ground-state spin equal to ten, the r

Publikováno v: Inorganica Chimica Acta. 361:3882-3886

We present a detailed investigation by magnetic measurements and EPR spectroscopy of the magnetic fraction of cigarettes and its variation with the smoking process. Our results indicate that both before and after smoking magnetic particles with a bro
