""Tyrian Purple"" unravels the fascinating story of one of history's most prized dyes, exploring its historical significance, complex production process, and economic impact. This comprehensive work delves into how a rare pigment extracted from sea snails shaped Mediterranean economies and social hierarchies for over a millennium. The book traces the journey of Tyrian purple from its discovery by the Phoenicians around 1570 BCE to its decline following the fall of Constantinople in 1453 CE. Readers will be intrigued to learn that Tyrian purple was once more valuable than gold, and its production was monopolized by the Roman Empire. The book combines archaeological findings, ancient texts, and modern scientific analyses to provide a multifaceted view of this luxury commodity. It explores the chemistry behind the dye's colorfast properties and examines the Murex species of sea snails from which it was extracted, seamlessly integrating concepts from marine biology and dye chemistry. Structured chronologically, ""Tyrian Purple"" presents a scholarly yet accessible narrative that weaves together historical facts, scientific analysis, and cultural studies. This interdisciplinary approach offers valuable insights into ancient trade networks, technological innovation, and the socioeconomic structures that shaped early civilizations, making it an engaging read for both academics and general audiences interested in the intersection of science and history.

The ancient industry of imperial purple dyeing was eradicated during the sack of Constantinople in 1453 and its secrets, purposefully kept mysterious, were lost with it. This booklet attempts a practical explanation of the micro-biological processes that could transform, as if by magic, the liquid from marine molluscs into an insoluble purple pigment. The methodology is accompanied by ancient and medieval references to the dye which was used to clothe Alexander the Great, Roman emperors and Christian rulers.

For a long time, travelers through the Mediterranean Sea sought after the handcrafted works of the Ancient Phoenicians, especially their Tyrian Purple Dye. It was said that only the rich could afford to wear purple because it was so expensive largely because of how they were made. This book will talk about the process of creating the Tyrian purple dye, and some of the other treasures the Ancient Phoenicians made and traded.

There are 196 countries on earth and none of them use purple on their national flag! What's wrong with purple? It's such a popular color today. Why would no country want it on their flag? Sometimes the simplest questions have the most extraordinary answers! This is the incredible true story of purple! Take a journey back to a time when purple dye was worth more than gold, diamonds or castles. This book was inspired by our original animation that has gone viral across the world. We decided to expand the story and enhance the art. Our mission is to make learning fun and to teach ideas that you won't necessarily find in a classroom.

Vol. 31, no. 1, Jan./Feb. 1928, commemorates "A quarter-century of the New York Aquarium."

This monograph features what happens when light meets molecules. This edited volume contains contributions from an international array of contributors, and it is divided into sections representing a selection of carefully focussed and connected photochemistry topics: energy, technology, medicine, environmental sciences, and art. In each section one or more chapters illustrates relevant aspects of each field, such as artificial photosynthesis and solar energy conversion (energy), light emitting devices and photochromic dyes (technology), and photodynamic therapy and solar filters (medicine). Aimed at students of all levels and researchers active in photochemistry.

This book deals with basic aspects of polymer electronics and optoelectronics. There is an enormous world-wide effort both in basic scientific research as well as in industrial development in the area of organic electronics. It is becoming increasingly clear that, if devices based on organic materials are ever going to have a significant relevance beyond being a cheap replacement for inorganic semiconductors, there will be a need to understand interface formation, film growth and functionality. A control of these aspects will allow the realisation of totally new device concepts exploiting the enormous flexibility inherent in organic chemistry. In this book we focus on oligomeric/molecular films as we believe that the control of molecular structures and interfaces provides highly defined systems which allow, on the one hand the study of the basic physics and on the other hand to find the important parameters necessary to improve organic devices.
