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 [...]

Thermal Conductivity and Viscosity Measurements of Water-Based Silica Nanofluids

Bobbo S., Colla L., Scattolini M., Agresti F., Barison S., Pagura C., Fedele L., CNR-Consiglio Nazionale delle Ricerche, IT

Nanofluids are a new class of fluids that could significantly improve the thermal properties of fluids used as thermal vectors. They are obtained by dispersing in common fluids (water, glycol, oil) solid nanoparticles (diameter <100 [...]

Synthesis and Characterization of Single Wall Carbon Nanohorns Produced by Direct Vaporization of Graphite

Pagura C., Schiavon M., Barison S., Battiston S., Consiglio Nazionale delle Ricerche, IT

A new patented process for massive production of single wall carbon nanohorn (SWCNH) is presented. Without any catalyst, the prototipe plant is able to produce 100 g/h of high purity carbon nanohorns. The direct vaporization [...]
