Photoactivity of Metal Oxides and Software used in Daylighting Arnab Bhattacharyya

This book is divided into three chapters. The first chapter deals with the softwares used for assessment of building's thermal and daylighting performance. These computer soft wares can be used to estimate the performance of different designs of the building under particular environmental condition. Getting the results, a designer can choose the design that is energy efficient and reliable for earning credit from various. The second chapter is based on the photo activity of Al based ferrites synthesized chemically. Photocatalysis is one of the unique, hassle free and non-hazardous techniques for recycling of waste water from industries and harnessing the potential of solar radiation. Al doped Ni Ferrites have the ability to degrade dyes. However fine tuning of physicochemical properties of the reaction system and characteristics of reactor plays a significant role for making photocatalytic degradation a large scale activity. The last chapter shows the effect of Ni and Zn dopping on the structural and optical properties of CuO which is a technologically important material. The defects incorporated and change in the crystallite size and the formation of new phases were addressed.
