This volume deals with chemistry of polyelectrolytes, namely biocide guanidine containing polymers, discussing both synthesis of new guanidine containing monomers of diallyl and acrylic nature and their structure and investigation of their radical (co)polymerization and properties of new (co)polymers. The first parts of the book describe radical polymerization of these monomers and their co-polymerization with diallyldialkylammonium derivatives, features of their kinetic behavior in these processes (for example, polymerization rates, reactivity ratios) The sections on phycal chemical methods (IR, NMR, DSC ect.) are especially important for studying of structure and properties of synthesized monomer and polymer compounds. The book is finely illustrated with about hundred original figures, schemes and tables including kinetics, NMR, IR spectroscopy, biocide and other data.

This book highlights many of the latest developments and trends in engineering chemistry research and describes the respective tools to characterize and predict properties and behavior of materials. The book provides original, theoretical, and important experimental results which use non-routine methodologies and presents chapters on novel applications of more familiar experimental techniques and analyses of composite problems which indicate the need for new experimental approaches presented. Technical and technological development demands the creation of new materials that are stronger, more reliable and more durable, i.e. materials with new properties. This volume presents new research that will help lead to new and better materials. Each chapter describes the principle of the respective method as well as the detailed procedures of experiments with examples of actual applications presented. Thus, readers will be able to apply the concepts as described in the book to their own experiments. Experts in each of the areas covered have reviewed the state of the art, thus creating a book that will be useful to readers at all levels in academic, industry, and research institutions. Engineers, polymer scientists, and technicians will find this volume useful in selecting approaches and techniques applicable to characterizing molecular, compositional, rheological, and thermodynamic properties of elastomers and plastics.

A comprehensive overview of different antimicrobial polymeric materials, their antimicrobial action modes and applications.

The book addresses the interdisciplinary scientific approach for the systemic understanding of connections between major human diseases and their treatment regime by applying the tools and techniques of nanotechnology. It also highlights the interdisciplinary collaborative researches for innovation in Biomedical Sciences. The book is a first volume which presents collection of best papers presented in the First International Conference on Infectious Diseases and Nanomedicine held during Dec. 15-18, 2012 in Kathmandu, Nepal. The book focuses mainly on the topics: emerging infectious diseases; antimicrobial agents, vaccines and immunity; drug design, drug delivery and tissue engineering and nanomaterials and biomedical materials.

The rapid increase in the emergence of antibiotic-resistant bacterial strains, combined with a dwindling rate of discovery of novel antibiotic molecules, has created an alarming issue worldwide. Although the occurrence of resistance in microbes is a natural process, the overuse of antibiotics is known to increase the rate of resistance evolution. Under antibiotic treatment, susceptible bacteria inevitably die, while resistant microorganisms proliferate under reduced competition. Therefore, the out-of-control use of antibiotics eliminates drug-susceptible species that would naturally limit the expansion of resistant species. In addition, the ability of many microbial species to grow as a biofilm has further complicated the treatment of infections with conventional antibiotics. A number of corrective measures are currently being explored to reverse or slow antibiotic resistance evolution, Among which one of the most promising solutions is the development of polymer-based antimicrobial compounds. In this Special Issue, different polymer systems able to prevent or treat biofilm formation, including cationic polymers, antibacterial peptide-mimetic polymers, polymers or composites able to load and release bioactive molecules, and antifouling polymers able to repel microbes by physical or chemical mechanisms are reported. Their applications in the design and fabrication of medical devices, in food packaging, and as drug carriers is investigated.

The design and development of dyes and chromophores have recently attracted much attention in various research fields such as materials, radiation curing, (laser) imaging, optics, medicine, microelectronics, nanotechnology, etc.. In this book, the recent research for the use of dyes and chromophores in polymer science is presented. The interaction of the visible light with the dyes or the selected chromophores is particularly important in different fields (e.g. for photovoltaic, display applications (LED ...), laser imaging or laser direct writing, green chemistry with sunlight induced photopolymerization etc ...). This book gives an overview of the dyes and chromophores for all the important fields.
