Colloid and Surface Chemistry

The decreasing rate of involvement in organized groups and with voting by young people is a disturbing trend that perhaps can be turned around. Becoming Citizens: Deepening the Craft of Youth Civic Engagement brings together civic education, experiential education, and political theory to provide a revealing multiple-perspective examination of the new alternative way of practice in the youth work field called civic youth work. This helpful resource bridges the theory of civic engagement with education, ground both in extensive data, and then discuss various youth civic engagement initiatives that battle apathy and effectively invite expanded involvement by young people. This title examines three different youth civic engagement initiatives, Public Achievement (PA), Youth in Government (YIG), and Youth Science Center (YSC). The book then discusses the initiatives from various perspectives, including the academic perspectives of educational theory, political theory, theories of youth, and vocation. This unique source offers multiple points-of-view and is designed to enrich both the theoretical and practical for practitioners and scholars-and provides a revealing and useful look at the available sources. This book is a valuable resource for secondary social studies teachers; school district curriculum coordinators; youth workers; university faculty in political theory, democratic theory, youth studies, child and youth care, recreational studies, public health, education, and social work; youth and community organizers; and program directors and managers in community-based youth services.This book was published as a special issue of Child and Youth Services.With principles that are shaping today's most advanced technologies, from nanomedicine to electronic nanorobots, colloid and interface science has become a truly interdisciplinary field, integrating chemistry, physics, and biology. Colloid and Surface Chemistry: Exploration of the Nano World- Laboratory Guide explains the basic principles of colloid and interface science through experiments that emphasize the fundamentals. It bridges the gap between the underlying theory and practical applications of colloid and surface chemistry.Separated into five chapters, the book begins by addressing research methodology, how to design successful experiments, and ethics in science. It also provides practical information on data collection and analysis, keeping a laboratory notebook, and writing laboratory reports. With each section written by a distinguished researcher, chapter 2 reviews common techniques for the characterization and analysis of colloidal structures, including surface tension measurements, viscosity and rheological measurements, electrokinetic methods, scattering and diffraction techniques, and microscopy.Chapters 3-5 provide 19 experiments, each including the purpose of the experiment, background information, pre-laboratory questions, step-by-step procedures, and post-laboratory questions. Chapter 3 contains experiments about colloids and surfaces, such as sedimentation, exploration of wetting phenomena, foam stability, and preparation of miniemulsions. Chapter 4 covers various techniques for the preparation of nanoparticles, including silver, magnetic, and silica nanoparticles. Chapter 5 demonstrates daily-life applications of colloid science, describing the preparation of food colloids, body wash, and body cream.
