Calcium phosphate based glasses with different concentrations of TiO2 (0 to 2.5 mol%) were prepared and their corresponding glass-ceramics were obtained by controlled heat treatments. The amorphous nature of glasses and the presence of crystalline phases in glass-ceramics were studied through XRD studies. Density, molar volume, ultrasonic velocities, attenuation, elastic constants and microhard...

DOI: 10.1002/adma.200904189 Microgels are particles made by chemically cross-linking a polymer to form particles of a gel that are colloidal in size. [ 1 , 2 ] Like their macroscopic counterparts, microgels can be swollen by a solvent, the degree of swelling depending on solvent quality and cross-link density. [ 3 , 4 ] As the solvent quality is governed by external stimuli such as temperature,...

Thiol-ene chemistry was exploited in droplet-based microfluidics to fabricate advanced microcapsules with tunable encapsulation, degradation, and thermal properties. In addition, by utilizing the thiol-ene photopolymerization with tunable cross-link density, we demonstrate the importance of monomer conversion on the retention of omniphilic cargo in double emulsion templated microcapsules. Furth...

Elastic effects in a model of disordered nematic elastomers are numerically investigated in two dimensions. Networks crosslinked in the isotropic phase exhibit an unusual soft mechanical response against stretching. It arises from a gradual alignment of orientationally correlated regions that are elongated along the director. A sharp crossover to a macroscopically aligned state is obtained on f...

A bottom-up approach was devised to build a crossbar device using the crosslinked SAM of the 5,5'-bis (mercaptomethyl)-2,2'-bipyridine-Ni(2+) (BPD- Ni(2+)) on a gold surface. To avoid metal diffusion through the organic film, the author used (i) nanoscale bottom electrodes to reduce the probability of defects on the bottom electrodes and (ii) molecular crosslinked technology to avoid metal diff...
