Reversible Long-Range Assemblies in Gold Nanoparticles – Liquid Crystal Composites: Molecular Dynamics of the Gold Capping Layer
Highly miscible mesogenic ligand capped gold nanoparticles (AuNPs) [1] 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 [...]
Surfactant-Activated Microgels
Chari K., Hsu R., Bhargava P., Figura B., Yang W., Park J., Clifford T., Kadir M., Benedikt G., Lubrizol Advanced Materials, US
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 as environmentally-friendly agents for cleaning artworks
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 [...]
Study of synergistic interactions between SiO2 nanoparticles and CTAB in the presence of NaCl: relationships with the formation and stabilization of hexadecane-in-water emulsions
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. [...]
Antioxidant and Antiradical SiO2 Nanoparticles Covalently Functionalized with Gallic Acid
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 [...]
Quatsomes: highly stable nanovesicles formed by sterols and
Ventosa N., Ferrer-Tasies L., Moreno-Calvo E., Cano-Sarabia M., Aguilella-Arzo M., Angelova A., Lesieur S., Ricart S., Veciana J., Faraudo J., CSIC, ES
Thermodynamically stable nanovesicular structures are of high interest for academia and industry in a wide variety of application fields, ranging from nanomaterials preparation to nanomedicine. Here we show the ability of quaternary ammonium surfactants and [...]
