Book Description
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.

Book Description
This textbook introduces the industrial production and processing of natural resources. It is divided into six major topics (fats and oils, carbohydrates, lignin, terpenoids, other natural products, biorefinery), which are divided into a total of 20 chapters. Each chapter is self-contained and therefore a compact learning unit, which can be worked on by students in self-study or presented by lecturers. Clear illustrations, flow diagrams, apparatus drawings and photos facilitate the understanding of the subject matter. All chapters end with a succinct summary, the "Take Home Messages". Each chapter is supplemented by ten short test questions, which can be solved quickly after working through the chapter; the answers are at the end of the book. All chapters contain bibliographical references that focus on essential textbooks and reference works. As a prior knowledge, only basic knowledge of chemistry is required.

Book Description
For centuries, dyed fabrics ranked among the most expensive objects of the ancient Mediterranean world, fetching up to 20 times their weight in gold. Huge fortunes were made from and lost to them, and battles were fought over control of the industry. The few who knew the dyes’ complex secrets carefully guarded the valuable knowledge. The Rarest Blue tells the amazing story of tekhelet, or hyacinth blue, the elusive sky-blue dye mentioned 50 times in the Hebrew Bible. The Minoans discovered it; the Phoenicians stole the technique; Cleopatra adored it; and Jews—obeying a Biblical commandment to affix a single thread of the radiant color to the corner of their garments—risked their lives for it. But with the fall of the Roman Empire, the technique was lost to the ages. Then, in the nineteenth century, a marine biologist saw a fisherman smearing his shirt with snail guts, marveling as the yellow stains turned sky blue. But what was the secret? At the same time, a Hasidic master obsessed with reviving the ancient tradition posited that the source wasn’t a snail at all but a squid. Bitter fighting ensued until another rabbi discovered that one of them was wrong—but had an unscrupulous chemist deliberately deceived him? Baruch Sterman brilliantly recounts the complete, amazing story of this sacred dye that changed the color of history.

Book Description
Despite the long association of organohalogen compounds with human activities, nature is the producer of nearly 5,000 halogen-containing chemicals. Once dismissed as accidents of nature or isolation artifacts, organohalogen compounds represent an important and ever growing class of natural products, in many cases exhibiting exceptional biological activity. Since the last comprehensive review in 1996 (Vol. 68, this series), there have been discovered an additional 2,500 organochlorine, organobromine, and other organohalogen compounds. These natural organohalogens are biosynthesized by bacteria, fungi, lichen, plants, marine organisms of all types, insects, and higher animals including humans. These compounds are also formed abiogenically, as in volcanoes, forest fires, and other geothermal events.In some instances, natural organohalogens are precisely the same chemicals that man synthesizes for industrial use, and some of the quantities of these natural chemicals far exceed the quantities emitted by man.

Book Description
A journey for readers through thousands of years extending from the innovation of silk & porcelain in China and paper & kohl in Pharaonic Egypt to the modern innovations in Europe and USA. This book introduces a summary of experiences for innovative nations through history. Imitation, copycatting, and knocking-off are the code that nations use as a response to the shock of “technological gap” before embarking on innovation.
