Development of a coupled diffusion denuder system combined with gas chromatography/mass spectrometry for the separation and quantification of molecul…
2009
This study concerns the development of a coupled diffusion denuder system capable of separating and quantifying gaseous molecular iodine (I(2)) and two other highly reactive iodine species, ICl and HOI, which are collectively named activated iodine compounds (AIC). Both I(2) and AIC are key species in the atmospheric chemistry of iodine. 1,3,5-Trimethoxybenzene (1,3,5-TMB)- and alpha-cyclodextrin/(129)I(-) (alpha-CD/(129)I(-))-coated denuders proved to be suitable for the collection of gaseous AIC and I(2), respectively. The experimental collection efficiencies for AIC (tested as ICl) and I(2) agreed well with the theoretical values for gas flow rates in the range between 300 and 1800 mL mi…
Extensive Evaluation of a Diffusion Denuder Technique for the Quantification of Atmospheric Stable and Radioactive Molecular Iodine
2010
In this paper we present the evaluation and optimization of a new approach for the quantification of gaseous molecular iodine (I(2)) for laboratory- and field-based studies and its novel application for the measurement of radioactive molecular iodine. alpha-Cyclodextrin (alpha-CD) in combination with (129)I(-) is shown to be an effective denuder coating for the sampling of gaseous I(2) by the formation of an inclusion complex. The entrapped (127)I(2) together with the (129)I(-) spike in the coating is then released and derivatized to 4-iodo-N,N-dimethylaniline (4-I-DMA) for gas chromatography-mass spectrometry (GC-MS) analysis. The (127)I(2) collected can be differentiated from the (129)I(-…

Chromogenic Detection of Aqueous Formaldehyde Using Functionalized Silica Nanoparticles
2016
Silica nanoparticles functionalized with thiol reactive units and bulky polar polyamines were used for the selective colorimetric detection of formaldehyde. The reaction of thiols groups in the nanoparticles surface with a squaraine dye resulted in loss of the pi-conjugation of the chromophores, and the subsequent bleaching of the solution. However, when formaldehyde was present in the suspension, the thiol-squaraine reaction was inhibited and a chromogenic response was observed. A selective response to formaldehyde was observed only when the thiol and polyamine groups were anchored to the silica surface. The observed selective response was ascribed to the fact that bulky polyamines generat…

CORPO (ATTI DI DISPOSIZIONE DEL)
2011
Il contributo sottopone a scrutinio la frammentata categoria degli atti di disposizione del corpo, ricostruendone alcune linee di regolamentazione rintracciabili nel sistema, anche per in-flusso della normativa europea e sovranazionale, e mettendo in evidenza profili di criticità e questioni interpretative ancora aperte: prima tra tutte quella dei limiti al potere dei privati di disporre di parti, elementi del proprio corpo e di dar vita ad un assetto di interessi di tipo esi-stenziale avente ad oggetto la propria sfera corporea.
Art. 2463 c.c.
2010
La pubblicazione contiene il commento all'art. 2463 c.c., soffermandosi in particolare sulle innovazioni normative legate alla riforma del diritto societario del 2003 (e successive integrazioni e modificazioni).L'analisi concerne la disciplina della costituzione della società a responsabilità limitata con atto unilaterale, i requisiti formali e contenutistici dell'atto costitutivo e dello statuto - con particolare attenzione alla differenziazione tra clausole obbligatorie e facoltative -, ed, infine, alcuni cenni conclusivi sui rinvii alla disciplina della società per azioni.
