A new electrochemical sensor for extra-virgin olive oils classification

Autor: Danilo Dini, Daniele Zappi, Claudia Sadun, Michela Antonelli, Lorenzo Gontrani

A screen-printed electrode was modified using multi-walled carbon nanotubes (MWCNT) and titanium oxide nanoparticles (TiO2), with a bio-based ionic liquid (RTIL) as a drop-casting medium. The RTILs here used have been proved to be useful for immobili

Evaluation of new cholinium-amino acids based room temperature ionic liquids (RTILs) as immobilization matrix for electrochemical biosensor development: Proof-of-concept with Trametes Versicolor laccase

Autor: Giancarlo Masci, Paolo Bollella, Claudia Sadun, Daniele Zappi, Marta Letizia Antonelli, Cristina Tortolini

Publikováno v: Microchemical Journal. 141:346-352

In this work, we present new cholinium-amino acids room temperature ionic liquids (ChAARTILs) that can be used as an efficient immobilization matrix for electrochemical biosensor development. The ideal immobilization strategy should be able to ensure

Deep eutectic solvents (DES) as green extraction media for antioxidants electrochemical quantification in extra-virgin olive oils

Autor: Liridon Berisha, Claudia Sadun, Danilo Dini, Marta Letizia Antonelli, Egzontina Shabani, Daniele Zappi

Publikováno v: Talanta. 215

A new electroanalytical method has been developed for the determination of polar antioxidant compounds in extra virgin olive oils. This method is based on the extraction of polar antioxidant compounds from extra-virgin olive oils by means of a deep e

Structure and dynamics of propylammonium nitrate-acetonitrile mixtures: An intricate multi-scale system probed with experimental and theoretical techniques

Autor: Lorenzo Gontrani, Marco Campetella, Claudia Sadun, Boning Wu, Alessandro Mariani, Edward W. Castner

In this article, we report the study of structural and dynamical properties for a series of acetonitrile/propylammonium nitrate mixtures as a function of their composition. These systems display an unusual increase in intensity in their X-ray diffrac

Synthesis of optically active trifluoromethyl substituted diaziridines and oxaziridines

Autor: Claudia Sadun, Lucio Pellacani, Stefania Fioravanti, Laura Carroccia, Paolo A. Tardella

Publikováno v: Tetrahedron. 67:5375-5381

(E)-Trifluoromethyl imines were considered as ideal substrates to be transformed into the corresponding diaziridines by a direct amination reaction with nosyloxycarbamates. The diastereoselective induction was strongly controlled by the N-substituent

Is a medium-range order pre-peak possible for ionic liquids without an aliphatic chain?

Autor: Serena De Santis, Ruggero Caminiti, Lorenzo Gontrani, Paolo Ballirano, Marco Campetella, Claudia Sadun, Luana Tanzi

The combination of amino acids anions with a choline cation gives origin to a new and potentially important class of organic ionic liquids that might represent a viable and bio-compatible alternative with respect to the traditional ones. We present h
