This book discusses recent advances in hydrogels, including their generation and applications and presents a compendium of fundamental concepts. It highlights the most important hydrogel materials, including physical hydrogels, chemical hydrogels, and nanohydrogels and explores the development of hydrogel-based novel materials that respond to external stimuli, such as temperature, pressure, pH, light, biochemicals or magnetism, which represent a new class of intelligent materials. With their multiple cooperative functions, hydrogel-based materials exhibit different potential applications ranging from biomedical engineering to water purification systems. This book covers key topics including superabsorbent polymer hydrogel; intelligent hydrogels for drug delivery; hydrogels from catechol-conjugated materials; nanomaterials loaded hydrogel; electrospinning of hydrogels; biopolymers-based hydrogels; injectable hydrogels; interpenetrating-polymer-network hydrogels: radiation- and sonochemical synthesis of micro/nano/macroscopic hydrogels; DNA-based hydrogels; and multifunctional applications of hydrogels. It will prove a valuable resource for researchers working in industry and academia alike.

A practical framework for thinking about the future... and an exploration of 'future consciousness' and how to develop it

Explains how anyone, even those who don't think they are 'creative' can confidently choose colours and patterns to create bold, easy-to-make quilts, perfect for today's busy craftspeople.

This book challenges the common assumption that the predominant focus of the history of science should be the achievements of Western scientists since the so-called Scientific Revolution. The conceptual frameworks within which the members of earlier societies and of modern indigenous groups worked admittedly pose severe problems for our understanding. But rather than dismiss them on the grounds that they are incommensurable with our own and to that extent unintelligible, we should see them as offering opportunities for us to revise many of our own preconceptions. We should accept that the realities to be accounted for are multi-dimensional and that all such accounts are to some extent value-laden. In the process insights from current anthropology and the study of ancient Greece and China especially are brought to bear to suggest how the remit of the history of science can be expanded to achieve a cross-cultural perspective on the problems.

This edited book serves as a vital resource on the contributions of microorganisms to advances in nanotechnology, establishing their applications in diverse areas of biomedicine, environment, biocatalysis, food and nutrition, and renewable energy. It documents the impacts of microorganisms in nanotechnology leading to further developments in microbial nanobiotechnology. This book appeals to researchers and scholars of microbiology, biochemistry and nanotechnology.

This book presents important developments and applications of green chemistry, especially in the field of organic chemistry. The chapters give a brief account of green organic reactions in water, green organic reactions using microwave and in solvent-free conditions. In depth discussions on the green aspects of ionic liquids, flow reactions, and recoverable catalysts are provided in this book. An exclusive chapter devoted to green Lewis acid is also included. The potential of supercritical fluids as green solvents in various areas of organic reactions is explained as well. This book will be a valuable reference for beginners as well as advanced researchers interested in green organic chemistry.

This volume looks at the different aspects involved in controlling microbial growth and the techniques employed in obtaining sterile surfaces. It covers research on coatings, nano-materials, herbal materials, naturally occurring antimicrobials in designing antimicrobial surfaces. It discusses issues of antibiotic resistance, synthesis techniques, toxicity, and current and potential applications of antimicrobial surfaces, and this book will serve as a useful reference to a broad range of scientists, industrial practitioners, graduate and undergraduate students, and other professionals in the fields of polymer science and engineering, materials science, surface science, bioengineering and chemical engineering.

'Superb' Sunday Times 'Revolutionary' Alice Roberts 'Hugely important' Jim Al-Khalili _______________ A radical retelling of the history of science that foregrounds the scientists erased from history In this major retelling of the history of science from 1450 to the present day, James Poskett explodes the myth that science began in Europe. The blinkered Western gaze focusing on individual 'genius' - Copernicus, Newton, Darwin, Einstein - was only one part of the story. The reality was an utterly global, non-linear pattern of cross-fertilization, competition, cooperation and outright conflict. Each rupture in history carved fresh channels for global exchange. Here, for the first time, Poskett celebrates how scientists from Africa, America, Asia and the Pacific were integral to this very human story. We meet Graman Kwasi, the African botanist who discovered a new cure for malaria; Hantaro Nagaoka, the Japanese scientist who first described the structure of the atom; and Zhao Zhongyao, the Chinese physicist who discovered antimatter. _______________ 'Remarkable. Challenges almost everything we know about science in the West' Jerry Brotton, author of A History of the World in 12 Maps 'Perspective-shattering' Caroline Sanderson, The Bookseller, 'Editor's Choice' 'Horizons upends traditional accounts of the history of science' Rebecca Wragg Sykes, author of Kindred 'Poskett deftly blends the achievements of little-known figures into the wider history of science . . . brims with clarity' Chris Allnutt, Financial Times

Horizons Math Kindergarten builds the foundation for the method of study that is used all the way through the Horizons Math program. Every concept follows a deliberate pattern of introduction and gradual development. Each lesson begins with a new concept or an expansion of a previously covered concept. This introduction starts a cycle of repetition and review that students will experience as they work through the lessons. Horizons Math Kindergarten lays a foundation for order and exactness. The daily practice in the student books teaches the recognition and printing of the numerals 0 to 100. Simple addition and subtraction from 0 to 10 are taught. the addition-subtraction concept is extended through 99 with the aid of counters and the number line. Counting through 100 is presented by 1's, 10's, 5's, 2's, 3's, and 4's. Principles of place value, measurement, calendar use, telling time, graphing, comparisons, and money concepts are also introduced.
