Journal ArticleDOI
Biopolymer Aerogels and Foams: Chemistry, Properties, and Applications.
Shanyu Zhao,Wim J. Malfait,Natalia Guerrero-Alburquerque,Matthias M. Koebel,Gustav Nyström,Gustav Nyström +5 more
TL;DR: The biopolymer aerogel field today is driven forward by empirical materials discovery at the laboratory scale, but requires a firmer theoretical basis and pilot studies to close the gap to market.
Journal ArticleDOI
Additive manufacturing of silica aerogels.
Shanyu Zhao,Gilberto Siqueira,Sarka Drdova,Sarka Drdova,David Norris,Christopher Ubert,Anne Bonnin,Sandra Galmarini,Michal Ganobjak,Michal Ganobjak,Zhengyuan Pan,Zhengyuan Pan,Samuel Brunner,Gustav Nyström,Gustav Nyström,Jing Wang,Jing Wang,Matthias M. Koebel,Wim J. Malfait +18 more
TL;DR: A direct ink writing protocol for silica aerogels enables 3D printing of lightweight, miniaturized objects with complex shapes, with the possibility to easily add functionality by incorporating nanoparticles.
Journal ArticleDOI
Strong, Thermally Superinsulating Biopolymer–Silica Aerogel Hybrids by Cogelation of Silicic Acid with Pectin
Shanyu Zhao,Wim J. Malfait,Arnaud Demilecamps,Yucheng Zhang,Samuel Brunner,Lukas Huber,Philippe Tingaut,Arnaud Rigacci,Tatiana Budtova,Matthias M. Koebel +9 more
TL;DR: A one-pot process to monolithic, superinsulating pectin-silica hybrid aerogels is presented and the change in the mechanical properties is directly linked to the observed "neck-free" nanoscale network structure with thicker struts.
Journal ArticleDOI
Effect of aging on silica aerogel properties
Subramaniam Iswar,Subramaniam Iswar,Wim J. Malfait,Sandor Balog,Frank Winnefeld,Marco Lattuada,Matthias M. Koebel +6 more
TL;DR: In this paper, the effect of aging on the physico-chemical properties of silica aerogel with emphasis on ambient dried materials was studied and the importance of aging to increase the ability of the gel particle network to withstand irreversible pore collapse during ambient pressure drying was highlighted.
Journal ArticleDOI
Supervolcano eruptions driven by melt buoyancy in large silicic magma chambers
Wim J. Malfait,R. Seifert,Sylvain Petitgirard,Jean-Philippe Perrillat,Mohamed Mezouar,Tsutomu Ota,Eizo Nakamura,Philippe Lerch,Carmen Sanchez-Valle +8 more
TL;DR: In this paper, the authors used synchrotron measurements of X-ray absorption to determine the density of silica-rich magmas at pressures and temperatures of up to 3.6 GPa and 1,950 K, respectively.
