TL;DR: 29Si NMR, small-angle X-ray scattering (SAXS), and dynamic light scattering (DLS) are used to monitor the synthesis of silica nanoparticles from the base-catalyzed hydrolysis of TEOS in methanol and ethanol to find that after an induction period where there is a buildup of singly hydrolyzed monomer, the first nuclei are fractal and open in structure.

TL;DR: In this paper, the authors quantified the stability of polystyrene-grafted silica nanoparticles (NPs) in PS matrices with ultrasmall angle X-ray scattering (USAXS) and transmission electron microscopy (TEM) and developed a phase diagram to predict NP dispersion based on the graft polymer density, σ, and the graft and free polymer molecular weights, or N and P, respectively.

TL;DR: In this paper, the first nanostructures appear at a hydrolyzed monomer concentration around 0.1 M, indicating that formation of the primary structures is thermodynamically controlled by a supersaturation of the intermediate species.

TL;DR: In this article, the viability of using photocatalytic oxidation with titanium dioxide to degrade Cd-EDTA was examined at concentrations from 2 × 10-5 to 10-3 M at pH from 3 to 8.

TL;DR: Using dynamic light scattering, mechanical rheometry, and visual observation, the static wetting behavior of PDMS-grafted silica spheres (PDMS- g-silica) in PDMS melts is related to their rheology, indicating a degree of aggregation that increases with increasing length of the free polymer, as suggested by the theory.
