Details the water research applications of nanotechnology in various areas including environmental science, remediation, membranes, nanomaterials, and water treatment At the nano size, materials often take on unique and sometimes unexpected properties that result in them being ‘tuned’ to build faster, lighter, stronger, and more efficient devices and systems, as well as creating new classes of materials. In water research, nanotechnology is applied to develop more cost-effective and high-performance water treatment systems, as well as to provide instant and continuous ways to monitor water quality. This volume presents an array of cutting-edge nanotechnology research in water applications including treatment, remediation, sensing, and pollution prevention. Nanotechnology applications for waste water research have significant impact in maintaining the long-term quality, availability, and viability of water. Regardless of the origin, such as municipal or industrial waste water, its remediation utilizing nanotechnology can not only be recycled and desalinized, but it can simultaneously detect biological and chemical contamination. Application of Nanotechnology in Water Research describes a broad area of nanotechnology and water research where membrane processes (nanofiltration, ultrafiltration, reverse osmosis, and nanoreactive membranes) are considered key components of advanced water purification and desalination technologies that remove, reduce, or neutralize water contaminants that threaten human health and/or ecosystem productivity and integrity. Various nanoparticles and nanomaterials that could be used in water remediation (zeolites, carbon nanotubes, self-assembled monolayer on mesoporous supports, biopolymers, single-enzyme nanoparticles, zero-valent iron nanoparticles, bimetallic iron nanoparticles, and nanoscale semiconductor photocatalysts) are discussed. The book also covers water-borne infectious diseases as well as water-borne pathogens, microbes, and toxicity approach.

The proletariat never existed-but it had a profound effect on modern German culture and society. As the most radicalized part of the industrial working class, the proletariat embodied the critique of capitalism and the promise of socialism. But as a collective imaginary, the proletariat also inspired the fantasies, desires, and attachments necessary for transforming the working class into a historical subject and an emotional community. This book reconstructs this complicated and contradictory process through the countless treatises, essays, memoirs, novels, poems, songs, plays, paintings, photographs, and films produced in the name of the proletariat. The Proletarian Dream reads these forgotten archives as part of an elusive collective imaginary that modeled what it meant-and even more important, how it felt-to claim the name "proletarian" with pride, hope, and conviction. By emphasizing the formative role of the aesthetic, the eighteen case studies offer a new perspective on working-class culture as a oppositional culture. Such a new perspective is bound to shed new light on the politics of emotion during the main years of working-class mobilizations and as part of more recent populist movements and cultures of resentment.
