1. Colloidal suspensions of mesostructured silica
Abstract : Mesoporous silica is a porous material with walls made of silica and pores in the size range of 2-50 nm. Since the silica most often is amorphous, the material lacks short range order but the pores may be arranged in different structures generating a long-range order. READ MORE

2. From Silica Nano-Particles to Silica Gels and Beyond - Salt Induced Aggregation of Silica Nano-Particles and the Stability of Resultant Gels
Abstract : Aqueous silica nanoparticle suspensions are widely available and used within a number of industries. A relatively new area of application is as a grouting material for sealing narrow fractures in tunnels. READ MORE

4. Formation of mesostructured silica based on non-ionic interactions
Abstract : Mesostructured silica is a material consisting of a silica matrix with an organization in the meso range of 2-50 nm. The silica matrix is most often amorphous while the organization, induced by a structure directing agent, may generate a long-range mesoorder. READ MORE

5. Toxicological and Immunomodulatory Properties of Mesoporous Silica Particles : Applications in Life Sciences
Abstract : Mesoporous silica particles offer great potential benefits as vehicles for drug delivery and in other biomedical applications. They present a high loading capacity due their ordered and size-tuneable pores that allow molecules to be loaded and released. READ MORE
