No full textSince 2003 the Chapter on Italian Copyright Law in the Treatise is written and updated every year by A. Musso (M. Fabiani had written it through 2002). As well as all the other national chapters (plus a chapter on European Law and a general Introduction), the "Italian" chapter deals with the Italian Law on Copyright and related rights, updated every year with all the relevant new provisions and the main decisions of higher and lower courts. In this 23rd release, a substantial and deeper review/update off all the issues related to copyright or related rights has been made by the Author, especially on links with international subject-matter (e.g. comparison of terms), on-line uses and possible infringement by Internet Service Providers (with changes in the main index, too). Due to the many entries in alphabetical order, every new release is divided in two papery volumes: the entry "Italy" is in Volume 2
Controlled oxidation of MWCNTs at low temperature
No full textCarbon nanotubes (CNTs) are an allotropic form of carbon, extremely interesting for their electrical and mechanical properties[1]. Used as reinforcement in different matrices, CNTs present many problems due to their agglomeration and non-wetting surface, that can be solved by chemical functionalization[2]. In particular, when dispersion in common solvents or matrices is considered, it is necessary to have polar functional groups on the surface. Since oxygen-containing groups are easy to graft on the CNTs surface, oxidation seems to be the best way to guarantee improved surface polarity. Oxidation through acid attack has been extensively studied in literature[3], since this changes the CNTs hydrophilicity and improves their dispersion in various solvents. However, the use of acids creates numerous drawbacks such as a heavy damaging of the CNTs structure due to the aggressive environment present during the oxidation reaction. This work originates from the need to find an oxidation method able to preserve the nanotubes structure while functionalizing the surface, in order to be able to disperse them in solvents or matrices but keeping the whole advantage given from the properties of the single CNTs. The idea was to perform a very simple oxidation of carbon nanotubes (CNTs) by thermal treatment at a specific temperature in controlled atmosphere. The conditions were chosen through a thermal gravimetric analysis (TGA) screening in a low oxygen (1-5%) atmosphere. The very initial phase of the thermal degradation starts between 350 C and 450 C, hence, the thermal degradation of CNTs was tested at lower temperatures with an isothermal treatment. By choosing the right temperature, time and amount of oxygen, it was possible to perform a precise and non-destructive oxidation of the CNTs, as demonstrated by several characterization techniques. This process enable the production of oxidized CNTs, which can be easily dispersed in aqueous solutions, without damaging the structure of the nanotubes
Piezoresistive cement nanocomposites
No full textMethods may include pumping a cement composition containing one or more conductive fillers into an annular region of a wellbore created between a casing and a surface of the wellbore, allowing the cement composition to cure, emplacing a tool for measuring at least one electromagnetic property into the wellbore, and measuring at least one of the cemented casing and the formation. In another aspect, methods may include preparing a cement composition containing one or more conductive fillers, allowing the cement composition to set, and measuring at least one electromagnetic property of the set cement. In yet another aspect, cement compositions may contain a cement, one or more conductive fillers, and a surfactant, wherein the resistivity of the cement composition is less than 10 Ω*

No full textFrom 2003 to 2016, Prof. Alberto Musso has written and up-dated every year this Chapter, priorly written by Prof. Mario Fabiani. In particular, since 2003, the Chapter has analyzed the main changes in Italian Copyright Law, both from European sources - the Italian implementation of Directive 2001/29/EC on the harmonisation of certain aspects of copyright and related rights in the information society (legislative decree N° 68/2003); of Directive 2001/84/EC on the resale right for the benefit of the author of an original work of art (Legislative Decree N° 118/2006); of Directive 2011/77/EU on the term of protection of copyright and certain related rights (Legislative Decree N° 22/2014); of Directive 2012/28/EU on certain permitted uses of orphan works (Legislative Decree N° 163/2014) - and from only national provisions (e.g. Articles 15, sec. 3, and 15-bis of the Italian Copyright Act on public performances of protected works in libraries, museums or cultural clubs.; the link with the Regulation of the Italian Authority on Communication about copyright protection on the net, pursuant to Article 32-bis of Legislative Decree N° 177/2005, and to Legislative Decree n° 9/2008 on audiovisual rights on sport events, etc.). These positive sources are always accompanied - also with criticism - by a wide description of case law and scholars' constructions of law and pratice of copyright and related rights in text and footnotes
Process for the production of dispersions of thermally oxidised carbon-based materials
No full textMethods of preparing dispersions of carbon-based materials are disclosed herein. In some embodiments, a method comprises exposing the carbon-based material to an atmosphere comprising between about 0.5% v/v and about 5.0% v/v of oxygen for a selected time at an oxidation temperature to obtain a thermally oxidized material; and dispersing the thermally oxidized material in a liquid medium
