Optochemical vapour detection using spin coated thin films of metal substituted phthalocyanines
Roberto Rella,Jolanda Spadavecchia,Giuseppe Ciccarella,Pietro Siciliano,G. Vasapollo,Ludovico Valli +5 more
TL;DR: In this article, a discussion concerning the data obtained with optical absorbance measurements in UV-Vis spectral range in controlled atmosphere is presented and a structural characterisation by using scanning electron microscopy has been performed and a different morphology of the sensitive layers obtained from different materials has been evidenced.

Optical recognition of organic vapours through ultrathin calix[4]pyrrole films
TL;DR: In this paper, thin films of meso-octaethylporphyrinogen were deposited on suitable surface by Langmuir-Blodgett technique in order to obtain optical sensors using Surface Plasmon Resonance (SPR)technique.

Stickstoffixierung: Reduktion von N2 durch vier Metallfragmente unter Bildung eines vierkernigen Samarium-Distickstoffkomplexes
TL;DR: In this article, a kooperative Angriff von vier (Dipyrromethanyl)SmII-Einheiten auf ein Stickstoffmolekul fuhrte zu einem vierkernigen Samarium-Distickstoffkomplex (schematisch gezeigt).

Spectroscopic investigation of inner filter effects by phthalocyanine solutions
Pier Paolo Pompa,Giuseppe Ciccarella,Jolanda Spadavecchia,R. Cingolani,G. Vasapollo,Ross Rinaldi +5 more
TL;DR: In this paper, a systematic investigation of phthalocyanine (Pc) optical properties, showing that the effect of reabsorption of fluorescence plays a critical role in the line-shape of Pc optical spectra.

Characterization of glutamate dehydrogenase immobilization on silica surface by atomic force microscopy and kinetic analyses
Laura Blasi,Luigia Longo,G. Vasapollo,R. Cingolani,Ross Rinaldi,T. Rizzello,Raffaele Acierno,Michele Maffia +7 more
TL;DR: The activity of immobilized GDH is critically dependent on the conditions for surface derivatization, and is inversely correlated with surface roughness.
