Ultralow friction of ink-jet printed graphene flakes
R. Buzio, A. Gerbi, S. Uttiya +7
We report the frictional response of few-layer graphene (FLG) flakes obtained by liquid phase exfoliation (LPE) of pristine graphite. To this end, we inkjet print FLG on bare and h…
Programmable Mechanical Resonances in MEMS by Localized Joule Heating of Phase Change Materials
Nicola Manca, Luca Pellegrino, Teruo Kanki +4
A programmable micromechanical resonator based on a VO2 thin film is reported. Multiple mechanical eigenfrequency states are programmed using Joule heating as local power source, g…
Grain size determination of superconducting MgB2 powders from magnetization curve, image analysis and surface area measurement
Maurizio Vignolo, Gianmarco Bovone, Emilio Bellingeri +5
The present article reports a method for the average grain size evaluation of superconducting nano-particles through their magnetic properties. The use of SQUID magnetometry to det…
A novel process to produce amorphous nano-sized B useful for MgB2 phase synthesis
Maurizio Vignolo, Gennaro Romano, Cristina Bernini +2
In this paper we report a new synthesis route to produce boron powders characterized as being amorphous and having very fine particle size. This route has been developed to improve…
High temperature heat treatment of B precursor and P.I.T. process optimization to increase Jc performances of MgB2-based conductor
Maurizio Vignolo, Gianmarco Bovone, Cristina Bernini +4
Promising results reported in our previous works led us to think that production of B powder plays a crucial role in MgB2 synthesis. A new method for boron preparation has been dev…
Long- to short-range magnetic order in fluorine-doped CeFeAsO
T. Shiroka, G. Lamura, S. Sanna +13
The evolution of the antiferromagnetic order parameter in CeFeAsO_{1-x}F_{x} as a function of the fluorine content x was investigated primarily via zero-field muon-spin spectroscop…
