We report on the synthesis of phase-pure TiO 2 nanoparticles in anatase, rutile and brookite
structures, using amorphous titania as a common starting material. Phase formation was …

Photochemical processes in heterogeneous systems have gained wide popularity in recent
years because of their wide applicationsin xerography, photography, chemical synthesis …

A model is proposed for the structure of calcium silicate hydrate (CSH) as it is formed during
the hydration of Portland cement. One purpose of the model is to move toward an ability to …

The synthesis and study of so-called “nanoparticles”, particles with diameters in the range of
1− 20 nm, has become a major interdisciplinary area of research over the past 10 years …

The procedures and the backgrounds for the formation of monodispersed colloidal particles
are reviewed, along with the personal view of the author's own, by classifying a wide variety …
