Ionomeric Films of Alginic Acid

Transparent, flexible films could be made by casting aqueous solutions of alginic acid, but they dissolved in water. When films were made from a solution of alginic acid and multivalent ions, they were still water soluble. However, when alginic acid films were immersed in a solution of salts with multivalent ions, they dissolved in water much more slowly, if at all. Treatment with calcium and z...

Hierarchical Porous Interlocked Polymeric Microcapsules: Sulfonic Acid Functionalization as Acid Catalysts

Owing to their unique structural and surface properties, mesoporous microspheres are widely applied in the catalytic field. Generally, increasing the surface area of the specific active phase of the catalyst is a good method, which can achieve a higher catalytic activity through the fabrication of the corresponding catalytic microspheres with the smaller size and hollow structure. However, one ...

Nanocrystalline iron oxide synthesised within Hierarchical Porous Silica prepared by nanoemulsion templating.

PIC (Phase Inversion Composition) O-W nanoemulsions was used as a template for the synthesis of Hierarchical Porous Silica (HPS), and the oil phase of the nanoemulsion was used as a nanoreactor for the preparation of magnetic gamma-Fe(2)O(3) nanoparticles, confined within the silica matrix.

Engineering polymeric composite particles by emulsion-templating: Thermodynamics versus Kinetics

We investigate the important factors that control the structure of polymeric particles fabricated from emulsion templates. We find that the most energetically stable structure predicted by interfacial energy analysis is not always achieved. The slow dynamic due to an increase in the viscosity of the emulsion phases prevents the polymeric particles to achieve their equilibrium structure. We devi...
