Self-assembled three-dimensional (3-D) colloidal crystals have been extensively utilized in nanolithography for fabricating a wide spectrum of functional periodic nanostructures for important technological applications. Here a simple and versatile way is reported using silica colloids to prepare close-packed particle multilayers by the Langmuir– Blodgett technique to create highly ordered 3-D colloidal crystals with unusual nanoarrays on a large variety of substrates.

The unique photophysical properties of the Ln(III) series has led to significant research efforts being directed towards their application in sensors. However, for “real-life” applications, these sensors should ideally be immobilised onto surfaces without loss of function.

Unmodified montmorillonite clay was utilized as a low cost adsorbent for the removal of heavy metals from a contaminated automobile effluent. Fourier transform infrared spectroscopy, Xray diffraction and scanning electron microscopy were used to characterize the adsorbent. Batch sorption experiments were performed at an optimum effluent pH of 6.5, adsorbent dose of 0.1 g, particle size of 100 lm and equilibrium contact time of 180 min. Thermodynamic analysis was also conducted. Equilibrium data were analyzed by the Langmuir, Freundlich, Temkin and Dubinin–Radushkevich models.

The photo catalytic efficiency of some TiO2 films (TiO2-ST01; TiO2-P25; TiO2 sol-gel) immobilized on glass has been investigated for the degradation of phenol in aqueous solution under UV light. It was shown that the best result obtained with TiO2-ST01 film, where the mineralization was the highest (70% TOC was removed after 3 hours of irradiations) and that related to the smaller particle size and the bigger surface areas of the TiO2-ST01 particles compared with TiO2-P25 and TiO2 sol-gel films. The effect of pH and phenol concentration were discussed.

This book is dedicated to the rapidly grown field of microporous ceramic membranes with separating layers of pore diameter less than 2 nm. In spite of the recent rapid growth of the research effort directed towards the development of microporous ceramic membranes the field is still considered to be at its infancy and exhibits a significant future growth potential.
