Journal ArticleDOI
New insight in the role of modifying ligands in the sol-gel processing of metal alkoxide precursors: A possibility to approach new classes of materials
Vadim G. Kessler,Gerald I. Spijksma,Gerald I. Spijksma,Gulaim A. Seisenbaeva,Sebastian Håkansson,David H.A. Blank,Henny J.M. Bouwmeester +6 more
TL;DR: In this article, the authors summarized recent literature data and presented new experimental data on the mechanisms of chemical modification, hydrolysis and polycondensation of the alkoxides and demonstrates possibilities to approach new classes of materials, exploiting these mechanisms.
Journal ArticleDOI
Microporous Zirconia–Titania Composite Membranes Derived from Diethanolamine-Modified Precursors
Gerald I. Spijksma,Cindy Huiskes,Nieck E. Benes,Henk Kruidhof,Dave H. A. Blank,Vadim G. Kessler,Henny J.M. Bouwmeester +6 more
TL;DR: In this article, the same authors proposed a multilayer polysilicon zirconia-titania composite membrane made from powders calcined at 400 °C with type I nitrogen sorption behavior.
Journal ArticleDOI
Stabilization and destabilization of zirconium propoxide precursors by acetylacetone.
TL;DR: In this paper, the stabilizing and destabilizing mechanism in the action of acetylacetone on zirconium propoxide precursors is revealed; the nature of heteroleptic intermediates provides an explanation.
Journal ArticleDOI
Chemistry of 2,2,6,6,-tetramethyl-3,5-heptanedione (Hthd) modification of zirconium and hafnium propoxide precursors.
Gerald I. Spijksma,Henny J.M. Bouwmeester,Dave H.A. Blank,Andreas Fischer,Marc Henry,Vadim G. Kessler +5 more
TL;DR: The compounds obtained from isopropoxide precursors showed a higher stability than those with n-propoxide ligands or a combination of both types and the unusually low solubility and volatility of MIV(thd)4 has been shown to be due to close packing and strong van der Waals interactions in the crystal structures of these compounds.
Journal ArticleDOI
CO2 sorption of a thin silica layer determined by spectroscopic ellipsometry
TL;DR: In this article, optical properties of a thin amorphous silica membrane and the supported γ-alumina layer on which it was coated were obtained from spectroscopic ellipsometry.
