Abstract. Porous poly(N-isopropylacrylamide) (PNIPAAm) hydrogels with pore diameters in the nanometer and micrometer range were synthesized using two variations of surfactant-based template method. We showed that smaller lead to faster swelling deswelling. A graphic representation a model describing kinetics explains assumption release uptake water is for larger specific surface area, diameters...

Independently controlling electronic and thermal transport in solids is a challenge, because these properties are coupled. Here, we show that disordered nanoporosity Ca3Co4O9 thin films can decrease the conductivity without significantly hampering transport. Scanning microscopy was used to determine out-of-plane estimate in-plane values. Nanoporous exhibit of 0.82 W m?1 K?1, which nearly twofol...

In compressive fracture of dry plexiform bone, we examine the individual roles of overall mean porosity, the connectivity of the porosity network, and the elastic as well as the failure properties of the nonporous matrix, using a random spring network model (RSNM). Porosity network structure is shown to reduce the compressive strength by up to 30%. However, the load-bearing capacity increases w...
