Colloidal silica is used in many applications including catalysis, pharmaceuticals, and
coatings. Although naturally formed silica materials are widely available, they are often in …

The control of the physicochemical properties of silica particles is of paramount importance
to achieve full functionality in specific applications. A novel facile method of silica particle …

Inactivated cell catalysis is one of several central techniques in green biomanufacturing
realm. However, the instability and leakage of enzymes in inactivated cell severely restrict …

This work presents the synthesis and characterization of hollow silica particles that were
fabricated with the asymmetric methyltrimethoxysilane (MTMS) as the only silica precursor …

The process to commercially synthesise silica particles with specific properties is a topic of
ongoing research since their use in industrial applications including catalysis, coatings and …

Polyamine-derived silica particles are proposed to grow due to primary particle (< 25 nm)
aggregation. On the basis of material balance, we propose an aggregation model to predict …

In this work, aqueous solutions of polymeric nuclei based on the polymer polyethyleneimine
(PEI), were characterized as a function of pH. The viscosity and zeta potential values of the …

Magnetic core-silica shell particles combine the physico-chemical properties of the silica
shell with the magnetic properties of the core. Seven possible particle coating methods …

The use of thin-film nanocomposite (TFN) membranes in water/waste treatment plants for the
removal of heavy metals has increased in the last few decades. TFN membranes utilise …

The thesis contains published scholarly work of which I am a co-author. For each such work
a written statement, endorsed by the other authors and my supervisor, attesting to my …
