Aminofunctional Starch Derivatives Synthesis Analysis And Application

This book effectively links the latest scientific advances to current technological applications of polymers, mainly focusing on biodegradable polymers obtained from biomass. The individual chapters were written by academic and industry researchers alike, introducing readers to topics that have received little attention in the literature to date. Key topics covered include polymers used in various areas such as food packaging, pharmaceuticals, energy production and the cosmetics industry, as well as the treatment of aqueous effluents.

Starch is the main source of energy to humans, but starch today has other roles in food, packing and pharmaceutical industries like filler, emulsion stabilizer, coating, etc. The native form of starch has application limitations on broad range of temperature, pH and stability, among others, required on several industrial applications. The alternative way is modified starch to improve its properties and uses on several industrial fields. The book explores the use of physical and, chemical modifications and even the unusual modification using ionizing radiation on several sources of starch, the effect of them on the properties and application fields of modified starch.

This is a laboratory guide that covers the early stages of syntheses. It offers guidance to the preparation of amino acid derivatives to be used in these broad area of synthesis as well as in amino acid analysis.

This book presents emerging economical and environmentally friendly polymer composites that are free of the side effects observed in traditional composites. It focuses on eco-friendly composite materials using granulated cork, a by-product of the cork industry; cellulose pulp from the recycling of paper residues; hemp fibers; and a range of other environmentally friendly materials procured from various sources. The book presents the manufacturing methods, properties and characterization techniques of these eco-friendly composites. The respective chapters address classical and recent aspects of eco-friendly polymer composites and their chemistry, along with practical applications in the biomedical, pharmaceutical, automotive and other sectors. Topics addressed include the fundamentals, processing, properties, practicality, drawbacks and advantages of eco-friendly polymer composites. Featuring contributions by experts in the field with a variety of backgrounds and specialties, the book will appeal to researchers and students in the fields of materials science and environmental science. Moreover, it fills the gap between research work in the laboratory and practical applications in related industries.

This thesis presents a theoretical and experimental approach for the rapid fabrication, optimization and testing of holographic sensors for the quantification of pH, organic solvents, metal cations, and glucose in solutions. Developing non-invasive and reusable diagnostics sensors that can be easily manufactured will support the monitoring of high-risk individuals in any clinical or point-of-care setting. Sensor fabrication approaches outlined include silver-halide chemistry, laser ablation and photopolymerization. The sensors employ off-axis Bragg diffraction gratings of ordered silver nanoparticles and localized refractive index changes in poly (2-hydroxyethyl methacrylate) and polyacrylamide films. The sensors exhibited reversible Bragg peak shifts, and diffracted the spectrum of narrow-band light over the wavelength range λpeak ≈ 495-1100 nm. Clinical trials of glucose sensors in the urine samples of diabetic patients demonstrated that they offer superior performance compared to commercial high-throughput urinalysis devices. Lastly, a generic smartphone application to quantify colorimetric tests was developed and tested for both Android and iOS operating systems. The sensing platform and smartphone application may have implications for the development of low-cost, reusable and equipment-free point-of-care diagnostic devices.

This book provides an essential overview of the science of polysaccharides. It both approaches polysaccharides as a polymer class and provides detailed descriptions of most major polysaccharides (cellulose, mannan, xylan, chitin-chitosan, cyclodextrines). Owing to the multidisciplinary character of the European Polysaccharide Network of Excellence (EPNOE), the book describes all main aspects of polysaccharide science and technology (biology, enzymology, physics, chemistry, materials science and processing). Notations and concepts follow a uniform format throughout the whole work in order to create a valuable reference book on the field of polysaccharide science. Owing to the major importance of industry in the EPNOE, concrete applications are also described in detail.
