Many of the important and creative developments in modern mathematics resulted from attempts to solve questions that originate in number theory. The publication of Emil Grosswald’s classic text presents an illuminating introduction to number theory. Combining the historical developments with the analytical approach, Topics from the Theory of Numbers offers the reader a diverse range of subjects to investigate.

This book is a collection of studies on state-of-art techniques developed for producing value-added N-containing chemicals and N-doped carbon materials from renewable sources via sustainable technologies. Aiming to improve conversion effectiveness and develop innovative techniques for new value-added N-containing products, topics in the text address recent advances, assess and highlight promising methods or technological strategies, and outline direct conversion routes for conversion of renewable resources to N-containing chemicals and materials. World-renowned authorities, experts, and professionals have contributed individual chapters in selected areas to cover the overall topic comprehensively. In addition to researchers and professionals in the field, educators teaching university courses on biomass transformation, biomass energy, energy materials, heterocyclic chemistry, resource materials and sustainable development and green chemistry will find the text informative with new international perspectives.
