Dynamic Light Scattering for the Characterization of Polydisperse Fractal Systems by the Example of Pyrogenic Silica
… used for the characterization of suspensions of pyrogenic silica which consists of fractal-like aggregates composed of sintered spherical primary particles. These structural features clearly complicate the understanding of DLS experiments and have been a severe obstacle to employing DLS as …

Understanding Functional Silica Additives for HDPE Composite Materials
… project was to study the impact of nanoscale pyrogenic silica additives on high-density polyethylene (HDPE) for the potential use as a liner material against corrosion in challenging environments such as oil and gas pipelines. The main body of work involves the analysis of the chemistry of …

The Influence of Amorphous, Sub-Micrometer Silica Particles in Cement Pastes and Mortars with Very Low Water-to-Cement Ratios (Ultra-High Performance Concrete)
… the influence of amorphous, sub-micrometer silica particles in UHPCs. The present literature is equivocal about whether silica enhances clinker hydration due to its dissolution and subsequent pozzolanic reaction to calcium–silicate–hydrate phases (C–S–H phases) and/or due to a heterogeneous …
