On the use of ionic liquids as mobile phase additives in high-performance liquid chromatography. A review.

2015

The popularity of ionic liquids (ILs) has grown during the last decades in several analytical separation techniques. Consequently, the number of reports devoted to the applications of ILs is still increasing. This review is focused on the use of ILs (mainly imidazolium-based associated to chloride and tetrafluoroborate) as mobile phase additives in high-performance liquid chromatography (HPLC). In this approach, ILs just function as salts, but keep several kinds of intermolecular interactions, which are useful for chromatographic separations. Both cation and anion can be adsorbed on the stationary phase, creating a bilayer. This gives rise to hydrophobic, electrostatic and other specific in…

Integrazione di celle fotovoltaiche ibride nel vetromattone

2012

L’invenzione riguarda l’integrazione del vetromattone con celle solari ibride (organiche/inorganiche), conosciute come Dye-sensitized Solar Cell (DSC). La combinazione del vetromattone con le DSC consente di migliorare le prestazioni del prodotto originario rendendolo in grado di produrre energia pulita. Le caratteristiche di trasparenza e isolamento termo-acustico del prodotto possono essere regolate agendo sulla configurazione delle DSC. Il prodotto può essere assemblato a formare pannelli fotovoltaici per la realizzazione di facciate traslucide energeticamente “attive” in varie condizioni luminose (condizioni di luce diffusa o artificiale) e indipendentemente dall’angolo di radiazione so…

The integration of Dye-sensitized Solar Cell (DSC) with the glassblock is disclosed. The combination of the two technological elements the glassblock and the DSC module enhance their own peculiarities. The final complete product is ready-made for installation owns the qualities of the glassblock and produces sustainable energy at the same time. The transparency and the thermo-acoustic insulation may be modulated according to the specific requirements of each case of installation. The product may be used for example to create PV panels for glazed and translucent façades that are able to perform efficiently in all light conditions (even in diffuse light also converting internal artificial light) that are not dependant on the angle of the solar radiation and do not suffer from the high operative temperatures of functioning due to the peculiarities of the DSCs. DSCs are made of economic and biocompatible materials and are produced with low-cost and highly productive printing methods on rigid or flexible substrates. With the integration of DSC modules with the glassblock PV panels coincide with the envelope itself so that they do not need any further structures to be installed on and allow the possibility of subtract from the price of the panel the price of the substituted building element allowing further economies. DSCs can be printed in different colours and with various patterns offering to designers and customers the possibility of intervening on the glassblock aesthetical aspect also taking advantage of the peculiar modularity of the glassblock for larger compositions of drawings on the building’s façade. Seven Hypotheses of integration are discussed in order to obtain DSC-integrated glassblock ready for the construction of a precast and dry-assembled PV panel which can use the horizontal and vertical cavities between the glassblocks to house plastic profiles where the electric interconnections and the steel bars -useful for improve the mechanical resistance of the panel- are integrated.Settore ICAR/10 - Architettura Tecnica

Pannello precompresso di vetromattoni assemblati a secco per la realizzazione di involucri traslucidi

2012

L’invenzione riguarda la realizzazione di un pannello di vetromattoni montati “a secco” -da impiegare per la realizzazione di involucri edilizi traslucidi anche nel caso di edifici alti- che è in grado di rispondere adeguatamente alle sollecitazioni orizzontali (quali quelle dovute a vento e sisma) grazie all’applicazione della tecnica della precompressione mondirezionale. Per offrire una risposta ai limiti imposti dalla tecnica di assemblaggio tradizionale dei vetromattoni (“ad umido”), l’applicazione della precompressione consente, infatti, di dare ai pannelli preassemblati “a secco” una rigidezza adeguata anche in direzione normale al loro piano di posa, sfruttando le buone caratteristic…

The invention is related to the construction of a glassblock panel “dry assembled” that can be used to build translucent building envelope even in high-rise buildings. This panel is able to contrast the horizontal actions due to wind and earthquake by means of the application of unidirectional pre-stressing technique. To overcame the limits due to the “wet assembly” system traditionally used to assemble the glassblocks the use of prestressing technique allow the panels to have an adequate mechanical resistance against the actions perpendicular to their installation plane. In this configuration the mechanical resistance of the glassblocks is exploited. The unidirectional prestressing (along the prevalent dimension of the panel) is obtained through the grip of the nuts inserted in the steel bars that are housed inside the glassblocks supporting profiles positioned in the vertical cavities between the glassblocks and passing through the horizontal profiles useful to separate glassblock rows from each other. The proper nuts grip opposing to the steel plates positioned at the top and bottom of the panel allow to prestress the panel. The steel plate are positioned on a plastic plate fixed to the lateral faces of the glassblocks by means of resins.Settore ICAR/10 - Architettura Tecnica

Droghe leggere e criminalità organizzata: una relazione problematica

2022

Il contributo analizza il tema dei rapporti tra trattamento penale delle droghe c.d. “leggere” e contrasto alla criminalità organizzata dedita al narcotraffico, con riguardo all’ordinamento europeo, internazionale e di alcuni Paesi dell’UE (Spagna, Portogallo, Grecia, Germania e Italia). Seguendo un approccio di tipo integrato, all’analisi del dato normativo si affianca la descrizione della fenomenologia dei traffici e la valutazione dei primi effetti che le riforme antiproibizioniste entrate in vigore in alcuni ordinamenti del Nord e del Sud America hanno prodotto sul fronte del mercato illecito. Il fine è di evidenziare i punti di forza e di debolezza dei modelli di depenalizzazione, tene…

The paper analyses the relationship between the criminal treatment of 'soft' drugs and the fight against organised crime related to drug trafficking with regard to European law international law and national criminal law of some EU countries (Spain Portugal Greece Germany and Italy). Following an integrated approach the analysis is carried on taking into consideration the phenomenology of trafficking and an assessment of the initial effects that the anti-prohibitionist reforms of some North and South American jurisdictions have produced on the illicit market. The aim is to highlight the strengths and weaknesses of the de-criminalisation models taking into account not only their theoretical profiles but also possible outcome on the fight against organised crime.Settore IUS/17 - Diritto Penale

The response behaviour of LiF:Mg,Cu,P thermoluminescence dosimeters to high-energy electron beams used in radiotherapy

1995

To ensure the effectiveness of radiation-therapy treatments, both in-phantom and in-patient reliable dose measurements are required. Thermoluminescence dosimeters are used commonly for both applications. Among the various available materials, the relatively new LiF:Mg,Cu,P phosphor is a suitable candidate for quality control of in vivo dosimetry in electron-beam therapy. The response behaviour of LiF:Mg,Cu,P chips to 6-21 MeV electron beams used in radiotherapy was studied. Batch homogeneity, dose linearity, sensitivity change after use, dose and dose-rate response, energy dependence and fading characteristics were investigated. The contribution from each factor to the overall uncertainty i…

Fermentation profiles of Manzanilla-Aloreña cracked green table olives in different chloride salt mixtures.

2010

NaCl plays an important role in table olive processing affecting the flavour and microbiological stability of the final product. However, consumers demand foods low in sodium, which makes necessary to decrease levels of this mineral in fruits. In this work, the effects of diverse mixtures of NaCl, CaCl2 and KCl on the fermentation profiles of cracked directly brined Manzanilla-Aloreña olives, were studied by means of response surface methodology based in a simplex lattice mixture design with constrains. All salt combinations led to lactic acid processes. The growth of Enterobacteriaceae populations was always limited and partially inhibited by the presence of CaCl2. Only time to reach half …

Refractometric sensor based on whispering-gallery modes of thin capillarie.

2009

Whispering-gallery modes resonances of submicron wall thickness capillaries exhibit very large wavelength shifts as a function of the refractive index of the medium that fills the inside. The sensitivity to refractive index changes is larger than in other optical microcavities as microspheres, microdisks and microrings. The outer surface where total internal reflection takes place remains always in air, enabling the measure of refractive index values higher than the refractive index of the capillary material. The fabrication of capillaries with submicron wall thickness has required the development of a specific technique. A refractometer with a response higher than 390 nm per refractive ind…
