Nonionic Triblock and Star Diblock Copolymer and Oligomeric Surfactant Syntheses of Highly Ordered, Hydrothermally Stable, Mesoporous Silica Structures
A family of highly ordered mesoporous (20−300 A) silica structures have been synthesized by the use of commercially available nonionic alkyl poly(ethylene oxide) (PEO) oligomeric surfactants and…
Chemistry of Zeolites and Related Porous Materials: Synthesis and Structure
wiley chemistry of zeolites and related porous materials chemistry of zeolites and related porous materials focuses on the synthetic and structural chemistry of the major types of molecular sieves it…
Generalized synthesis of periodic surfactant/inorganic composite materials
THE recent synthesis of silica-based mesoporous materials1,2 by the cooperative assembly of periodic inorganic and surfactant-based structures has attracted great interest because it extends the…
Organization of Organic Molecules with Inorganic Molecular Species into Nanocomposite Biphase Arrays
The organization of cationic or anionic organic and inorganic molecular species to produce three-dimensional periodic biphase arrays is described. The approach uses cooperative nucleation of…
Cooperative Formation of Inorganic-Organic Interfaces in the Synthesis of Silicate Mesostructures
Model Q230 proposed by Mariani and his co-workers satisfactorily fits the x-ray data collected on the cubic mesostructure material and suggests that the silicate polymer forms a unique infinite silicate sheet sitting on the gyroid minimal surface and separating the surfactant molecules into two disconnected volumes.
Commercially activated carbon as the source for producing multicolor photoluminescent carbon dots by chemical oxidation.
Using commercially activated carbon, we developed a simple and effective direct chemical oxidation route to prepare good biocompatible multicolor photoluminescent carbon dots.
Surfactant Control of Phases in the Synthesis of Mesoporous Silica-Based Materials
The low-temperature formation of liquid-crystal-like arrays made up of molecular complexes formed between molecular inorganic species and amphiphilic organic molecules is a convenient approach for…
Chemistry of Zeolites and Related Porous Materials
Dye-doped silica nanoparticle labels/protein microarray for detection of protein biomarkers.
Results illustrated that the assay is highly specific for IL-6 in the presence of range of cytokines or proteins, and the RuDS dye-labeled nanoparticles in connection with protein microarrays show the promise for clinical diagnosis of biomarkers.
Mesostructure Design with Gemini Surfactants: Supercage Formation in a Three-Dimensional Hexagonal Array
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.
