Principles of Colloid and Surface Chemistry, Revised and Expanded

Abstract: This work aims to familiarize students with the fundamentals of colloid and surface science, from various types of colloids and colloidal phenomena, and classical and modern characterization/measurement techniques to applications of colloids and surface science in engineering, technology, chemistry, physics and biological and medical sciences. The Journal of Textile Studies proclaims "High praise from peers . . .contains valuable information on many topics of interest to food rheologists and polymer scientists …[The book] should be in the libraries of academic and industrial food research organizations" and Chromatographia describes the book as "…an excellent textbook, excellently organised, clearly written and well laid out."

TiO2 Photocatalysis: A Historical Overview and Future Prospects

Abstract: Photocatalysis has recently become a common word and various products using photocatalytic functions have been commercialized. Among many candidates for photocatalysts, TiO2 is almost the only material suitable for industrial use at present and also probably in the future. This is because TiO2 has the most efficient photoactivity, the highest stability and the lowest cost. More significantly, it has been used as a white pigment from ancient times, and thus, its safety to humans and the environment is guaranteed by history. There are two types of photochemical reaction proceeding on a TiO2 surface when irradiated with ultraviolet light. One includes the photo-induced redox reactions of adsorbed substances, and the other is the photo-induced hydrophilic conversion of TiO2 itself. The former type has been known since the early part of the 20th century, but the latter was found only at the end of the century. The combination of these two functions has opened up various novel applications of TiO2, particularly in the field of building materials. Here, we review the progress of the scientific research on TiO2 photocatalysis as well as its industrial applications, and describe future prospects of this field mainly based on the present authors' work.

Interfacial Lifshitz-van der Waals and polar interactions in macroscopic systems

Abstract: The concept of a general attractive interaction between neutral atoms was first proposed by van der Surface Thermodynamics of (Lewis) Waals in 1873, to account for certain properties of Acid-Base (AB) Interactions nonideal gases and liquids.’ Three different but nevThe Young-Dupr6 Equation 933 ertheless related phenomena were subsequently shown to contribute to these “van der Waals” interactions: (1) randomly orienting dipole-dipole (or orientation) inPositive and Negative Interfacial
