Influence of pigments on the photoactivity of TiO2-containing colored mortars compared with white mortars and sol-gel TiO2 application route

Diamanti M.V., Del Curto B., Ormellese M., Pedeferri MP., Politecnico di Milano, IT

In previous works, TiO2-containing commercial mortars were proved to show photoactivated properties due to the well-known semiconducting structure of titanium dioxide in anatase form. Anatase was added to white mortars in form of suspension or [...]

Enriched methane production by solar steam reformer: process evaluation

De Falco M., Marrelli L., Giaconia A., Tarquini P., University of Rome “La Sapienza”, IT

The aim of this work is to present a novel hybrid plant for the production of a mixture of methane and hydrogen from a steam reforming reactor whose heat duty is supplied by a molten [...]

Influence of MWNT on the physical properties of polyethylene nanocomposites

Ciambelli P., Sarno M., Neitzert H.C., Nobile M.R., Somma E., Valentino O., University of Salerno, IT

Physical properties of a series of multi-walled carbon nanotube-high density polyethylene (MWNT-HDPE) composites, prepared by melt mixing in a micro-twin screw extruder, were investigated. The effect of MWNT concentration (0.5-7 wt%) and nanotube surface treatment [...]

Tribological properties of carbon nanotubes as lubricant additives

Abate F., Senatore A., D’Agostino V., Leone C., Sarno M., Ciambelli P., University of Salerno, IT

Tribological performances of innovative lubricant additives based on IF-WS2 and other transition metal dichalcogenides like MoS2 nanoparticles have been widely investigated in recent years. The boundary lubrication regime is the main target for the benefits [...]

Morphological variations on titanium by AC anodizing

Diamanti M.V., Ormellese M., Pedeferri MP., Politecnico di Milano, IT

Besides the widely investigated photoinduced properties of its oxides, a primary branch of application of anodized titanium is the production of biomedical implants, where a controlled roughness can lead to improvements in cell adhesion and [...]

Photoactivity of nitrogen-doped anodic TiO2 under UV and VIS light irradiation

Diamanti M.V., Ormellese M., Pedeferri M.P., Politecnico di Milano, IT

Titanium dioxide is probably the most efficient among the known photocatalysts, and undoubtedly the most studied one. An appealing route to tune obtain TiO2 films morphology and structure is to exploit the anodizing process to [...]

ROMP of norbornene catalysed by Grubbs functionalized carbon nanotubes

Longo P., Costabile C., Grisi F., Siniscalchi G., Ciambelli P., Sarno M., Leone C., Sannino D., University of Salerno, IT

Recently, carbon nanotubes have attracted attention for their unique structural and electronic properties, which position them as one of the leading materials for a wide array of potential nanotechnological applications. The synthesis of homogeneuos polymeric [...]

Precise positioning of particles in microwells within horizontal DEP cages

Lombardini M., Bocchi M., Giulianelli L., Guerrieri R., ARCES, IT

The analysis and manipulation of one or few biological cells or artificial particles in the micron size range is a fundamental requirement in various life sciences applications such as sorting of rare cells or high-efficient [...]

Synthesis of monodispersed MFe2O4 (M=Fe, Co, Ni) ferrite nanoparticles: effect of reaction temperature on particle size

Altavilla C., Leone C., Sannino D., Sarno M., Ciambelli P., University of Salerno, IT

The possibility of preparing monodispersed transition metal-oxides nanoparticles covered by functionalized long chain organic molecules, in the sub size range of 20 nm, has recently open an entire field of research. In fact, inorganic core [...]
