Highly miscible mesogenic ligand capped gold nanoparticles (AuNPs)  that produce reversible long-range assemblies in nematic and smectic liquid crystal (LC) [2-3] were recently developed by our group. At the isotropic-to-nematic phase transition of cyanobiphenyl [...]

We describe a new class of nonionic (non-polyelectrolyte) microgels comprising crosslinked amphiphilic copolymers of alkyl acrylates and hydroxyalkyl esters that are activated by surfactant instead of pH. We discuss the mechanism of action of these [...]
Micellar solutions and microemulsions are efficient agents for cleaning artworks, especially for the selective removal of aged polymeric coatings from the surface of wall paintings. We have aimed at the development of a generalized method [...]
The synergistic interactions between silica (SiO2) nanoparticles and a surfactant cetyltrimethylammonium bromide (CTAB) on the shear viscoelastic properties of the hexadecane-water (H/W) interfacial films as well as the formation and stability of emulsions were investigated. [...]
Gallic acid (GA) and its derivatives are natural polyphenolic substances widely used as antioxidants in nutrients, medicine and polymers. Here, nanoantioxidant materials are engineered by covalently grafting GA on SiO2 nanoparticles (NPs). A proof-of-concept is [...]
