Journal ArticleDOI
Heat Treatment of Alumina Aerogels
TL;DR: In this paper, the phase conversions and morphological changes of alumina aerogel films and monoliths during heat treatment were investigated by TGA/DTA, BET, XRD, and image analysis of SEM micrographs.
Journal ArticleDOI
High solids loading ceramic colloidal dispersions in UV curable media via comb-polyelectrolyte surfactants.
TL;DR: A general scheme for relatively high loading/low viscosity dispersions of nanometer and submicrometer particles in UV curable resins using comb-polyelectrolyte surfactants is presented and particle stabilization and transfer schemes, rheological behavior and UV curing characteristics are presented.
Journal ArticleDOI
Highly loaded UV curable nanosilica dispersions for rapid prototyping applications
TL;DR: In this article, the authors present the development of >40vol.%, UV curable transparent silica nanodispersions having viscosities suitable for stereolithography applications, and the transformation of selected dispersions to self-supporting silica glass sheets through UV curing, debinding and sintering was investigated by TGA/DTA, dilatometry and XRD.
Journal ArticleDOI
Robotic deposition of 3d nanocomposite and ceramic fiber architectures via UV curable colloidal inks
TL;DR: In this paper, a robotic approach for producing predetermined, complex 3D ceramic architectures by robotic deposition where UV radiation is used for solidification is presented, where homogeneous, highly loaded, solvent free colloidal inks with controlled viscoelastic properties are achieved by proper selection of monomers and surfactants.
Journal ArticleDOI
Rheology of UV curable colloidal silica dispersions for rapid prototyping applications
TL;DR: In this article, highly filled, low viscosity silica dispersions (up to 60vol%) in UV curable, acrylate-based systems were investigated, and the influence of silica particle size, solid loading, temperature and shear rate on the viscosities of dispersions was investigated.
