Early report of the synthesis and characterization of highly ordered mesoporous inorganic materials synthesized as powders under highly acidic conditions using nonionic block copolymers. The resulting materials possessed channels with uniform adjustable pore dimensions between 5 and 30 nm and thicker pore walls that led to improved hydrothermal stability compared to similar materials prepared using low-molecular-weight surfactants.

This paper describes the synthesis of mesoporous silica fibers possessing long-range hexagonal mesostructural order using low-molecular-weight surfactants to coassemble laser dye species. Control over the morphology and dimensions of the fibers is demonstrated through control of the self-assembly and growth mechanisms, which lead to orientationally ordered hexagonal mesopores within the fibers and waveguide properties.
