Mesoscopic structural organization in triphilic room temperature ionic liquids
Room temperature ionic liquids are one of the most exciting classes of materials in the last decade. The interest for these low melting, ionic compounds stems from both their technological impact and the stimulating plethora of structural and dynamic peculiarities in the mesoscopic space-time scales. It is nowadays well-established that they are characterised by an enhanced degree of mesoscopic order originating from their inherent amphiphilicity. In this contribution we highlight the existence of a further degree of mesoscopic complexity when dealing with RTILs bearing a medium length fluorous tail: such triphilic materials (they simultaneously contain polar, hydrophobic and fluorophilic m…
Liquid structure and dynamics in the choline acetate:urea 1:2 deep eutectic solvent
We report on the thermodynamic, structural, and dynamic properties of a recently proposed deep eutectic solvent, formed by choline acetate (ChAc) and urea (U) at the stoichiometric ratio 1:2, hereinafter indicated as ChAc:U. Although the crystalline phase melts at 36-38 degrees C depending on the heating rate, ChAc:U can be easily supercooled at sub-ambient conditions, thus maintaining at the liquid state, with a glass-liquid transition at about -50 degrees C. Synchrotron high energy x-ray scattering experiments provide the experimental data for supporting a reverse Monte Carlo analysis to extract structural information at the atomistic level. This exploration of the liquid structure of ChA…
Analysis of IL-6, IL-10 and IL-17 genetic polymorphisms as risk factors for sepsis development in burned patients.
Abstract Infection risk, sepsis and mortality after severe burn are primarily determined by patient age, burn size, and depth. Whether genetic differences contribute to otherwise unexpected variability in outcomes is unknown. We sought to determine whether there was an association between IL-6, IL-10 and IL-17 polymorphisms with cytokine production and development of sepsis. We evaluated 71 patients with burns ≥15% TBSA and 109 healthy subjects. The genotypes of IL-6 (−174C/G), IL-10 (−819C/T and −1082A/G) and IL-17 (7488T/C) polymorphisms were identified applying polymerase chain reaction protocols. The cytokine levels in serum were determined with enzyme-linked immunoabsorbent assays. Our…
Confronto XRF – LIBS per la caratterizzazione chimico-fisiche dei materiali lapidei provenienti dal teatro greco-romano di Taormina
Vengono messe a confronto due tecniche spettroscopiche, la fluorescenza a raggi X (XRF) e la ablazione indotta da laser pulsato (LIBS), al fine di caratterizzare la composizione chimico-fisica di materiali lapidei naturali e non provenienti dal teatro Greco-Romano di Taormina. Entrambe le tecniche permettono un’analisi integrata, offrendo la LIBS la possibilità di ottenere informazioni stratigrafiche. Verranno presentati i risultati di analisi XRF e LIBS effettuate in situ e in laboratorio sui campioni prelevati nel teatro. L’interpretazione quantitativa delle analisi LIBS è stata effettuata mediante una tecnica standarless, ossia che non richiede l’uso di standard e denominata tecnica Cali…
