Journal ArticleDOI
Mesocellular siliceous foams with uniformly sized cells and windows
Patrick Schmidt-Winkel,Wayne W. Lukens,Dongyuan Zhao,Peidong Yang,Bradley F. Chmelka,Galen D. Stucky +5 more
TL;DR: The mesocellular foams (MCFs) as discussed by the authors are composed of uniformly sized, large spherical cells that are interconnected by uniform windows to create a continuous 3D pore system.
Journal ArticleDOI
Microemulsion Templating of Siliceous Mesostructured Cellular Foams with Well-Defined Ultralarge Mesopores
Patrick Schmidt-Winkel,Wayne W. Lukens, Jr.,†,‡,Peidong Yang,David I. Margolese,John S. Lettow,Jackie Y. Ying, ,§ and,Galen D. Stucky +6 more
TL;DR: In this paper, the mesostructured cellular foams (MCFs) with well-defined ultralarge mesopores and hydrothermally robust frameworks are described, and the pore size can be controlled by adjusting the amount of the organic swelling agent that is added and by varying the aging temperature.
Journal ArticleDOI
Evaluating Pore Sizes in Mesoporous Materials: A Simplified Standard Adsorption Method and a Simplified Broekhoff−de Boer Method
TL;DR: In this article, a simple method for determining standard adsorption using the statistical thickness of the adsorbed gas layer defined by Frenkel−Halsey−Hill (FHH) theory is described.
Journal ArticleDOI
Hexagonal to Mesocellular Foam Phase Transition in Polymer-Templated Mesoporous Silicas
John S. Lettow,Yong-Jin Han,Patrick Schmidt-Winkel,Peidong Yang,Dongyuan Zhao,Galen D. Stucky,Jackie Y. Ying +6 more
TL;DR: In this paper, the phase transition between two distinct mesoporous silicas, SBA-15 and MCF, was investigated, and it was shown that the phase-transition occurs at an oil−polymer mass ratio of 0.2−0.3.
Journal ArticleDOI
Fluoride-Induced Hierarchical Ordering of Mesoporous Silica in Aqueous Acid-Syntheses
TL;DR: In this paper, Zhao et al. describe the hierarchical ordering effects induced by small amounts of fluoride added during the synthesis of SBA-15-type mesoporous silica under acidic aqueous conditions.
