On the use of polymeric additives to promote plasma separation from whole blood in open microchannels

Lee E., Berthier J., Laurent P., Navarro F., Cubizolles M., CEA, FR

Polymers additives in whole blood are known to modify blood physical properties. For example, Dextran molecules usually accelerate the aggregation of re-suspended RBCs in Ringer solutions. In this work, we first investigate the effect of [...]

Optical characterizations of multi-shape nanoparticles in polymer thin film layers

Carlberg M., Pourcin F., Margeat O., Le Rouzo J., Berginc G., Sauvage R.-M., Ackermann J., Escoubas L., Aix Marseille University, FR

Metallic nanoparticles are currently a hot topic thanks to their tuneable optical properties. Indeed, their light absorption or scattering is material, size and shape, but also environment dependent. We aim to take advantage of these [...]

Large-scale manufacturing of radiation sculptured therapeutic nanogels

Dispenza C., Grimaldi N., Sabatino M.-A., Adamo G., Rigogliuso S., Ghersi G., Università di Palermo, IT

Pulsed electron-beam irradiation of poly(N-vinyl pyrrolidone) (PVP) aqueous solutions, at relatively low energy per pulse and doses within the sterilization dose range, has led to a variety of PVP nanogels of controlled size, that can [...]

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 [...]

Effects of Poly-(N-vinyl-2-pyrrolidone) Additive on Direct-Inkjet-Printed Silver Nitrate Conductive Lines

Liu Y-F, Feng P.H., Tsai H.L., Hwang W-S, National Cheng Kung University, TW

All-printed electronics has attracted attention due to their fast processing and low cost. Inkjet printing allows circuit components to be directly drawn at a specific area in one step. The printed patterns can be used [...]
