The book "Novel Optical Resolution Technologies" offers a comprehensive insight into the advancements and developments in the field of crystallization, particularly in the context of optical resolution. Since the end of the 20th century, the science of crystallization has transformed into a dynamic discipline that provides both theoretical and experimental opportunities. The authors Kenichi Sakai, Noriaki Hirayama, and Rui Tamura illuminate the complex processes underlying crystallization and demonstrate how modern high-performance computers enable the modeling of these processes. The book addresses the close collaboration between crystallization science and other disciplines such as biology, materials science, and chemistry. It becomes clear that crystallization extends far beyond traditional applications in the pharmaceutical industry and represents a significant research field that offers both intellectual and industrial opportunities.
