A novel family of nanocarbon‐based materials were designed, synthesized, and probed within the context of charge‐transfer cascades. In details, we implemented fine‐tuned chains of photo‐ and redox‐active constituents. For the first time, we integrated electron‐donating ferrocenes with light‐harvesting /electron‐donating (metallo)porphyrins and electron‐accepting graphene nanoplates (GNP) into multicomponent conjugates. To control the rate of charge flow between the individual building blocks, we bridged them via oligo‐ p ‐phenyleneethynylenes of variable lengths.

In this work the results deriving from the characterization of materials used by Lucio Fontana to realize some of his artworks are presented. Specifically, object of analyses are three artworks from the collection of National Gal- lery of Modern and Contemporary Art in Rome, whose complex composition required the combination of differ- ent diagnostic techniques for a complete characterization.

Milk is a complex emulsion of fat and water with proteins (such as caseins and whey), vitamins, minerals and lactose dissolved within. The purpose of this study is to automatically distinguish different dairy residues on substrates commonly used in the food industry using hyperspectral imaging. Fourier transform infrared (FT-IR) and Raman hyperspectral imaging were compared as candidate techniques to achieve this goal. Aluminium and stainless-steel, types 304-2B and 316-2B, were chosen as surfaces due to their widespread use in food production.

In this study, we report a detailed experimental and theoretical investigation of three glycol
derivatives, namely ethane-1,2-diol, 2-methoxyethan-1-ol and 1,2-dimethoxy ethane. For the first
time, the X-ray spectra of the latter two liquids was measured at room temperature, and they were
compared with the newly measured spectrum of ethane-1,2-diol. The experimental diffraction patterns
were interpreted very satisfactorily with molecular dynamics calculations, and suggest that in liquid

In this study, polythiophene copolymers have been used as modifier for electrode surfaces in order to allow the immobilization of active pyrroloquinoline quinone dependent glucose dehydrogenase (PQQ-GDH) and to simultaneously improve the direct electrical connection of the enzyme with the electrode. Polymer films are electrosynthesized in aqueous solution without the need of surfactants onto carbon nanotubes modified gold electrodes from mixtures of 3-thiopheneacetic acid (ThCH2CO2H) and 3-methoxythiophene (ThOCH3) using a potentiostatic pulse method.
