Bulk modulus of poly(N-isopropylacrylamide) microgels through the swelling transition.

We report measurements of the bulk modulus of individual poly(N-isopropylacrylamide) microgels along their swelling transition. The modulus is determined by measuring the volume deformation of the microgel as a function of osmotic pressure using dextran solutions. We find that the modulus softens through the transition, displaying a nonmonotonous behavior with temperature. This feature is corre...

On the bulk modulus of the transition metals

2014 The effect of correlations and ferromagnetic order on the bulk modulus K of the 3d metals is discussed using a second order perturbation treatment of the correlation. For elements in the middle of the series with a low density of states n(EF) at the Fermi level, ferromagnetic order, if possible, acts together with correlation to reduce K. The ferromagnetic elements Fe, Co and Ni lie toward...

Rheological properties of suspensions of thermo-responsive poly(N-isopropylacrylamide) microgels undergoing volume phase transition

The rheological properties of suspensions of thermo-responsive poly(N-isopropylacrylamide) (PNIPAM) microgels are investigated in the swollen and collapsed states using oscillatory and long-time creep measurements. In the swollen state with repulsive interparticle interaction, the zero shear viscosity and quasi-plateau modulus are solely governed by the effective volume fraction (φeff) and are ...

Volume Transition and Internal Structures of Small Poly(N-isopropylacrylamide) Microgels

Monodispersed poly(N-isopropylacrylamide) (PNIPAM) nanoparticles, with hydrodynamic radius less than 50 nm at room temperature, have been synthesized in the presence of a large amount of emulsifiers. These microgel particles undergo a swollen–collapsed volume transition in an aqueous solution when the temperature is raised to around 34 °C. The volume transition and structure changes of the micr...

Swelling Kinetics of Disulfide Cross-Linked Microgels

Hydrogels of 2-hydroxyethyl methacrylate (HEMA) cross-linked with N,N′-cystaminebis(acrylamide) (CBA) were prepared inside microchannels using an in situ photopolymerization for the study of chemical-responsive microgels. By chemically reducing disulfide bonds with dithiothreitol (DTT), the cross-link density of the hydrogel network decreased, leading to an observable swelling of the hydrogel. ...
