There are examples aplenty in the macroscopic world that demonstrate the form of objects directing their functions and properties. On the other hand, the fabrication of extremely small objects having precisely defined structures has only recently become an attractive challenge, which is now opening the door to nanoscience and nanotechnology.In the field of synthetic polymer chemistry, a number of critical breakthroughs have been achieved during the first decade of this century to produce an important class of polymers having a variety of cyclic and multicyclic topologies. These developments now offer unique opportunities in polymer materials design to create unprecedented properties and functions simply based on the form, i.e. topology, of polymer molecules.In this book on topological polymer chemistry, the important developments in this growing area will be collected for the first time, with particular emphasis on new conceptual insights for polymer chemistry and polymer materials. The book will systematically review topological polymer chemistry from basic aspects to practice, and give a broad overview of cyclic polymers covering new synthesis, structure characterization, basic properties/functions and the eventual applications.
It was no time to fear animals when the possibility of the enemy counteroffensive was increasing. It didn't suit a soldier to lose nerve in the presence of a mere crocodile At the end of World War II, a garrison of the Twenty-eighth Japanese Army is deployed to Ramree Island, off the coast of Burma, to fight the Allies' severe counteroffensive. While on the island, Superior Private Minoru Kasuga questions a local villager about the terrible smell coming from the saltwater creek. To his horror, the old man tells him it is the stench of death from the breath of man-eating crocodiles that inhabit Myinkhon Creek. Fierce fighting drives the battalion to the island's east coast, and they must evacuate to Burma by crossing the creek. Just before they embark, Kasuga smells the same putrid odor that he'd questioned the villager about and warns his commanding officer of the underwater danger. His sergeant ignores him, thinking Kasuga is obsessed with wild stories from the villagers, and he tells the soldiers to cross the creek. Ordered to save the penned-in garrison, Second Lieutenant Yoshihisa Sumi arrives on Ramree Island. But what awaits him at Myinkhon Creek is a sight too horrible to contemplate
