Redox properties of H(2)TFcP [TFcP(2-) = 5,10,15,20-tetraferrocenylporphyrin(2-)] were investigated using cyclic voltammetry, differential pulse and square-wave voltammetry methods in a large variety solvents electrolytes. When DMF, THF, MeCN used with TBAP as the supporting electrolyte, first oxidation wave was assigned to single four-electron process reflecting simultaneous all iron(II) centers into iron(III) H(2)TFcP. an o-DCB (1,2-dichlorobenzene)/TBAP combination electrochemical...
Aim: Fabrication of graphene oxide (GO)-based medical devices coatings that limit adhesion Candida albicans, a main issue healthcare-associated infections. Methods: The GO composites noncovalently functionalized with curcumin (CU), hydrophobic molecule active antimicrobial action, polyethylene glycol (PEG) hinders the absorption biomolecules or combination CU and PEG (GO–CU–PEG) were drop-casted on surfaces antifungal efficacy was assessed. Results: We demonstrate GO–CU–PEG can reduce fungal...
We probed a series of multicomponent electron donor2–donor1–acceptor1 conjugates both experimentally and computationally. The are based on the light harvester primary electron-donor zinc-porphyrin (ZnP, donor1) to whose β positions secondary ferrocene (Fc, donor2) electron-acceptor C60-fullerene (C60, acceptor1) attached. Linking all them via p-phenylene-acetylene/acetylene bridges different lengths gain full control over shuttling electrons holes between C60, ZnP, Fc is novel. Different...
A reversible electrochemical behavior is demonstrated on a specially prepared redox-functionalized H−Si(100) surface, obtained via an extra-mild grafting procedure from vinylferrocene. The results of detailed XPS and characterization the resulting hybrid are reported discussed to propose it as reference system for high-quality electroactive monolayers Si. investigated ferrocene derivative bears functional group suitable mild route covalent anchoring Si, which based photoinduced reaction with...
Nanocrystals obtained by growing a protecting ZnS shell onto photoactive ZnTe core afford nanocrystals that can represent alternatives to cadmium-based quantum dots.
A novel experimental approach to produce graphene/silicon interface is reported, which consists of electrochemically reduced graphene oxide directly in contact with Si(111). The utilized procedure makes use differently concentrated solutions drop-casted onto a flat crystalline hydrogenated Si(111) surface. Such modified surface was as working electrode an electrochemical cell aqueous electrolyte and subject cyclic voltammetry different conditions. After the treatments, electrodes were...
Graphene, one of the allotropic forms carbon, has attracted enormous interest in last few years due to its unique properties. Reduced graphene oxide (RGO) is known as nanomaterial most similar terms electronic, chemical, mechanical, and optical It prepared from (GO) presence different types reducing agents. Nevertheless, application RGO still limited, owing tendency irreversibly aggregate an aqueous medium. Herein, we disclosed preparation water-dispersible GO previously enriched with...
Graphene oxide (GO) is known to be a 2D metastable nanomaterial that can reconstructed under thermal annealing into distinct oxidized and graphitic phases. Up now, such phase transformation, mainly related epoxide hydroxyl functional groups, has been usually achieved by thermally treating layers of GO in the solid state. Here, we present mild dispersed an aqueous medium, performed at two temperatures, 50 °C 80 °C, for different intervals time. We show experimental evidences instability...
