Journal ArticleDOI
Nonionic Triblock and Star Diblock Copolymer and Oligomeric Surfactant Syntheses of Highly Ordered, Hydrothermally Stable, Mesoporous Silica Structures
TL;DR: In this paper, a family of highly ordered mesoporous (20−300 A) structures have been synthesized by the use of commercially available nonionic alkyl poly(ethylene oxide) (PEO) oligomeric surfactants and poly(alkylene oxide) block copolymers in acid media.
Journal ArticleDOI
Surfactant Control of Phases in the Synthesis of Mesoporous Silica-Based Materials
TL;DR: In this article, the molecular shapes of covalent organosilanes, quaternary ammonium surfactants, and mixed surfactant in various reaction conditions can be used to synthesize silica-based mesophase configurations.
Journal ArticleDOI
Mesostructure Design with Gemini Surfactants: Supercage Formation in a Three-Dimensional Hexagonal Array
TL;DR: Gemini surfactants, with two quaternary ammonium head groups separated by a methylene chain of variable length, can be used to control organic charge sitting relative to the bivariable hydrophobic tail configurations, leading to a mesophase (SBA-2) that has three-dimensional hexagonal (P63/mmc) symmetry, regular supercages that can be dimensionally tailored, and a large inner surface area.
Journal ArticleDOI
Self-Assembly of Ionic Surfactants in Polyelectrolyte Solutions: A Model for Mixtures of Opposite Charge
TL;DR: In this paper, a thermodynamic model of polyelectrolyte/surfactant interactions is derived, which considers the binding of polyion chains to the surface of oppositely charged surfactant micelles.
Journal ArticleDOI
Compaction of DNA by gemini surfactants: effects of surfactant architecture.
TL;DR: The interaction between bacteriophage T4 DNA and cationic gemini surfactants was studied by the use of fluorescence microscopy and the dependence on valency of the head group is found to be similar to what is known for mono- and multivalent ions.
