Full-Spectrum Responsive Photocatalytic Materials

From Fundamentals to Applications

By: Chuanyi Wang,Yanyan Duan,Lan Wang,Qiuhui Zhu

Full-Spectrum Responsive Photocatalytic Materials: From Fundamentals to Applications provides a comprehensive overview on the design, synthesis concepts, mechanisms, characterization techniques, and advances and limitations in applications of full-spectrum responsive photocatalytic materials. The book starts with the fundamentals of full-spectrum responsive materials. It then discusses the problems of most semiconductors that are not active in the whole solar spectrum and explains the benefits of utilizing full-spectrum responsive photocatalysts. Other sections describe examples of full-spectrum responsive photocatalysts classified by material types and provide the design principles and characterization protocols for these promising materials. Photocatalysis technology based on semiconductor materials holds great promise in various fields due to its potential advantages in energy-saving, cost and environmental impact. Maximizing the utilization of solar energy is always the target of pursuits in the areas of photocatalysis, and understanding and constructing appropriate full-spectrum (UV-VIS-NIR) responsive photocatalytic materials offer ways to better realize the practical utilization of photocatalysis. - Provides new insights into full-spectrum (UV-VIS-NIR) responsive photocatalysts and successful approaches for developing these materials - Assists readers working to develop more efficient catalysts and establish a solid structure–activity correlation - Suggests possibilities for the alteration of conventional photocatalysts to utilize the full spectrum of solar light

Developing Chinese EFL Learners' Generic Competence

A Genre-based & Process Genre Approach

By: Liming Deng,Qiujin Chen,Yanyan Zhang

This work investigates the development of English as a Foreign Language (EFL) learners’ generic competence in reading, writing and translation within the particular Chinese classroom context. It provides a new perspective for the current teaching and research in reading, writing, translation within the EFL contexts and offers an insightful framework for pedagogical applications in language learning and teaching. Its findings will be extremely valuable not only in local situations, but also more generally in a wider regional and global context as well. The book employs a series of research tools, including pre-research and post-research questionnaires, pre-test and post-test of reading/writing/translation, multi-faceted writing portfolios (including reflection reports), textual analysis and in-depth interviews. It involves 209 participants from a primary university in Wuhan, among whom 171 are undergraduates and 38 are postgraduates. And it draws on the analysis of such varied multi-sourced data both qualitatively and quantitatively. Genre-based teaching is playing a critical role in initiating EFL learners into the discourse community of the target language. Developing EFL learners’ generic competence is viewed as the ultimate goal in the process of teaching and learning. This monograph effectively demonstrates that like genre-based English for Specific Purposes (ESP) pedagogies, it is also possible to take advantage of already acquired genre knowledge for use in EFL learning contexts. It offers an impressive view of the direction in which genre-based applications are likely to take in the coming years.

Contingent Valuation of Yangtze Finless Porpoises in Poyang Lake, China

By: Yanyan Dong

This book presents the findings of the study, and offers analysis of both its methodological and policy-related implications. On the methodology side, it assesses and validates the valuation workshop approach; appraises the effect of distance on willingness to pay and the influence of the respondents’ ability to pay. From a policy perspective, the book examines the attitudes and preference of respondents on trade-offs between economic growth and ecological use.

Cameras and Display Systems Towards Photorealistic 3D Holography

By: Jin Li,Jintao Hong,Yi Zhang,Xiaoxun Li,Zilong Liu,Yanyan Liu,Daping Chu

This book presents recent advances in three-dimensional (3D) imaging and display frameworks, encompassing three categories of 3D imaging and display technologies. The first category is nonphotorealistic 3D approaches based on conventional optical cameras to implement 3D stereoscopic observation of a scene. In the context of nonphotorealistic 3D imaging and reconstruction systems, the authors introduce general principles and also demonstrate camera calibration for 3D imaging, smart cameras, and full-link imaging methods using the optical modulation transfer function to improve imaging quality in conventional cameras. The second category is based on light-ray light field technology to achieve photorealistic 3D imaging and displays. In the context of light-ray light field systems, two approaches capable of light-ray light field 3D imaging by utilizing a camera array or a lens array are demonstrated. Accordingly, light-ray light field display approaches comprising head-mounted displays and integral displays are also introduced. The third category is also photorealistic 3D imaging and display technology, which is based on holography (i.e., diffraction or wavefront light field). In the corresponding holographic displays, the authors introduce 3D holographic displays from three elements: algorithms, devices, and systems, involving fast hologram generation algorithms, wide-viewing-angle display systems, and metasurface holography, etc. Including an investigative roadmap for future progress in optical imaging and 3D display systems, this book is essential reading for scientists and engineers in academia and industry who are interested in next-generation imaging and display concepts for 3D visual sensing systems.
