This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study focuses on using this novel heating technology to carryout highly energy intensive polymerization process. L-lactic acid polymerization was carried out under microwave heating. High molecular weight poly (l-lactic acid) was synthesized with or without using Sn-octoate catalyst. Polymerization time was reduced to a few hours under microwave heating compared to 24 to 48 hours required by conventional polymerization process. Increase in the reaction rates were attributed to both thermal and non thermal heating effects of microwave. Copolymeric blend of immiscible polymers like PLLA and PGA were also prepared using microwave heating, resulting in blends which exhibited uniformity, block copolymerization and good compatibility. Insitu synthesis of hydroxyapatite during lactic acid polymerization under microwave heating resulted in high molecular weight PLLA with nano to micron scale hydroxyapatite particles embedded in the matrix. Degradation of low molecular weight microwave synthesized PLLA showed bulk degradation and have been shown as potentials for drug delivery applications.

Available in PDF, EPUB and Kindle. Book excerpt: Algae Based Polymers, Blends, and Composites: Chemistry, Biotechnology and Material Sciences offers considerable detail on the origin of algae, extraction of useful metabolites and major compounds from algal bio-mass, and the production and future prospects of sustainable polymers derived from algae, blends of algae, and algae based composites. Characterization methods and processing techniques for algae-based polymers and composites are discussed in detail, enabling researchers to apply the latest techniques to their own work. The conversion of bio-mass into high value chemicals, energy, and materials has ample financial and ecological importance, particularly in the era of declining petroleum reserves and global warming. Algae are an important source of biomass since they flourish rapidly and can be cultivated almost everywhere. At present the majority of naturally produced algal biomass is an unused resource and normally is left to decompose. Similarly, the use of this enormous underexploited biomass is mainly limited to food consumption and as bio-fertilizer. However, there is an opportunity here for materials scientists to explore its potential as a feedstock for the production of sustainable materials. Provides detailed information on the extraction of useful compounds from algal biomass Highlights the development of a range of polymers, blends, and composites Includes coverage of characterization and processing techniques, enabling research scientists and engineers to apply the information to their own research and development Discusses potential applications and future prospects of algae-based biopolymers, giving the latest insight into the future of these sustainable materials
