We report direct visual evidence for the association of particles in stable magnetic fluids in zero magnetic field, observed with cryo-transmission electron microscopy. The rather isotropic shape of the reversible associates indicates that isotropic

A synthesis method is introduced for very small uniform gold particles (diameter less than 5 nm), based on the reduction of hydrogen tetrachloroaurate(III) in ethanol in the presence of (γ-mercaptopropyl)trimethoxysilane (MPS). The surface layer of

A simple method is presented for the preparation of small silica spheres with a diameter of about 32 nm with a well-defined shape and smooth surface. The method comprises the dilution of an aqueous sodium-silicate solution with excess ethanol. The re

The aging of the aluminum tridecamer in acidified aluminum sec-butoxide is studied with 27Al nuclear magnetic resonance. At 20°C the tridecamer content passes through a maximum of 19.7% after 133 h of aging to decline subsequently to a final content

Fairly monodisperse colloidal boehmite fibrils with a high aspect ratio were synthesized by hydrothermal treatment at 150°C of an acidified aqueous alkoxide solution, prepared by adding an aqueous HCl solution to an aluminum alkoxide precursor. The

Dispersions of colloidal boehmite (γ-AlOOH) rods (of controllable length) are prepared from alkoxide precursors. A polyisobutene grafting procedure leads to sterically stabilized dispersions. In the organophilic system (L ≈ 200 nm ± 50%; D ≈ 10

The synthesis of colloidal boehmite (AlOOH) is studied by heating basic aluminum chloride solutions under constant stirring. The temperature and Al2O3: Cl molar ratio influence the product morphology. Synthesis at 140°C generates highly fibrous poly

Dispersions are called colloidal when the dispersed particles are larger than common small molecules, say larger than 1 nm, but small enough not to show appreciable sedimentation in normal gravity, say smaller than 1 μm. Colloidal particles are equi

We report the phase behavior of aqueous dispersions containing rodlike boehmite particles with two different average lengths, 130 and 280 nm, with length-to-width ratios of approximately 8 and 20, over a range of ionic strengths. At low salt concentr
