This book introduces the theory and applications of nanometer photocatalysis, and it briefly presents the concept of photocatalysts, photocatalytic reaction mechanisms and kinetics, and photocatalytic reactor design. In addition, the use of photocatalysis in the control of flue-gas pollutants is discussed in detail. The book also describes how a photocatalytic reactor is designed and implemented to evaluate the photocatalytic oxidation capaci...

A multi-scale morphological analysis of the Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5) was performed. We adapted the Metric Space Technique to perform a space-scale morphological analysis by filtering the galaxy point distributions with a smoothing Gaussian function, thus giving quantitative structural information on a range of scale sizes. The analysis was performed on 2-D (a dozen slices of a volume of space containing many newly m...

The fractal dimension of the spatial distribution of galaxies can be characterized by various statistical and topological methods, such as the Two-point Correlation Function, Perimeter-Area, Box Counting, and the Gamma Function. Here we develop a new way to get fractal information, that is the Metric Space Technique (MST). It allows multiple measures to be simultaneously applied for quantitative analysis of any type of structure distribution. ...

The value of the fractal dimension D of the universe is important for us to understand the evolution of the universe. Many methods have been developed to get the fractal dimension. To supplement the widely used methods, here we generalize the Metric Space Technique (MST), a tool used to analyze and classify astrophysical maps and perform a multi-scale analysis and get the fractal dimension of the early and current universe. We consider a wide ...
