High Performance Supercapacitors Based on Thermal Reduced Graphene Oxide

Perego D., Franz S., Bestetti M., Borioli C., Politecnico di Milano, IT

THERMALLY REDUCED GRAPHENE OXIDE BASED SUPERCAPACITORS HAVE BEEN FABRICATED AND TESTED. ELECTRODES BASED ON METAL SUBSTRATE (TI, AISI304, NI, AL) WERE FABRICATED BY EITHER BY ELECTROPHORESIS AND SPRAY COATING OF GRAPHENE OXIDE SOLUTIONS. ELECTROCHEMICAL TEST [...]

Influence of molecular weight of PVP on aggregation and thermal diffusivity of silver-based nanofluids

Agresti F., Barison S., Battiston S., Pagura C., Colla L., Fedele L., Fabrizio M., National Research Council of Italy (CNR), IT

With the aim of preparing stable nanofluids for heat exchange applications and to study the effect of surfactant on the aggregation of nanoparticles and thermal diffusivity, stable silver colloids were synthesized in water by a [...]

Reduction of the Hydrophobicity of Thiol-ene Microfluidic Devices Using an Adsorbed Polymeric Coating

Cretich M., Zilio C., Chiari M., Consiglio Nazionale delle Ricerche, IT

Thiol-ene based materials have gained a considerable interest in the field of micro and nano fluidics because of their physico-chemical properties and their polymerization characteristics. Unfortunately, the hydrophobic nature of this material represents a considerable [...]

Green synthesis of noble metal and bimetal nanosols and their applications as catalysts

Blosi M., Ortelli S., Albonetti S., Costa A.L., Ortolani L., Dondi M., Istec-CNR, IT

We report an environmentally benign approach to the production of stable metals nanosols. Water has been chosen as benign solvent, glucose serve as a mild, renewable and non-toxic reducing agents and microwave irradiation was used [...]

C-AFM as a means to identify heterogeneities at the nanoscale in thin anodic TiO2 films

Diamanti M.V., Souier T., Chiesa M., Pedeferri MP., Politecnico di Milano, IT

The anodic oxidation of titanium allows the obtaining of an oxide layer with thickness, color, homogeneity and insulating properties that depend on the process parameters. TiO2 thin films have been studied mostly to derive information [...]

TiO2-based photocatalytic and antimicrobial coatings: comparison between sol-gel and electrodeposited silver/TiO2 nano-composites

Diamanti M.V., Magagnin L., Del Curto B., Candiani G., Pedeferri MP., Politecnico di Milano, IT

Among possible ways to improve air quality in urban atmospheres, the use of nanostructured TiO2 films as photocatalysts is an excellent way to mitigate the problem, although it cannot offer a complete solution. TiO2 also [...]

Hydrogen permeation in pipeline steels

Fallahmohammadi E., Bolzoni F., Fumagalli G., Re G., Lazzari L., Politecnico di Milano, IT

In a previous phase of this research, two sour service pipeline steels, a carbon steel API 5L X65 and a low alloy one ASTM A182 F22, showed a remarkable reduction of the fracture toughness after [...]

Cancer cell targeting of lipid gene vectors by protein corona

Caracciolo G., Pozzi D., Capriotti A.L., Cavaliere C., Cardarelli F., Bifone A., Laganà A., Sapienza University of Rome, IT

We investigated the compositional evolution of the protein corona of 1,2-dioleoyl-3-trimethylammonium propane (DOTAP) cationic liposomes (CLs) that efficiently deliver DNA in a wide variety of cell lines as a function of increasing human plasma (HP) [...]
