Book excerpt: L'auteur étudie les réactions intervenant au cours du chauffage entre différents phosphates de calcium (phosphate tricalcique anhydre Ca3(PO4)2 (βTCP) ; hydroxyapatite Ca10(PO4)6(OH)2 ; phosphate tricalcique apatitique Ca9(HPO4)5(OH) d'une part et le sulfate d'ammonium d'autre part. Il montre que ces réactions font intervenir différentes phosphates condensés et le sulfate de calcium. Lors de la réaction avec l'hydroxyapatite on otient un soilde de structure βTCP contenant CaSo4, tandis qu'au cours des réactions avec βTCP ou le phosphate tricalcique apatitique, on obtient toujours βTCP pur. Une nouvelle série de solides de structure βTCP et contenant CaSO4 (phosphosulfate de calcium ) a été mise en évidence. Sa composition limite correspondrait à la formule (Ca23 )(PO4)14(SO4)2. Ces matériaux constituent de nouvelles biocéramiques. Techniques d'étude utilisé : ATG, R-X, IR, analyse chimique, chromatographie sur papier, mesures de masses volumiques.

Available in PDF, EPUB and Kindle. Book excerpt: Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. The biological substances include such items as meat, poultry, lettuce, beer, and milk as examples. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes areas such as water, vitamins, minerals, enzymes, food additives, flavours, and colours. This discipline also encompasses how products change under certain food processing techniques and ways either to enhance or to prevent them from happening. An example of enhancing a process would be to encourage fermentation of dairy products with lactic acid; an example of a preventing process would be stopping the Maillard reaction on the surface of freshly cut Red Delicious apples whether by hand or mechanical methods. This book presents the recent research from around the world in this field.

Available in PDF, EPUB and Kindle. Book excerpt: Encapsulations, a volume in the Nanotechnology in the Agri-Food Industry series,presents key elements in establishing food quality through the improvement of food flavor and aroma. The major benefits of nanoencapsulation for food ingredients include improvement in bioavailability of flavor and aroma ingredients, improvement in solubility of poor water-soluble ingredients, higher ingredient retention during production process, higher activity levels of encapsulated ingredients, improved shelf life, and controlled release of flavor and aroma. This volume discusses main nanoencapsulation processes such as spray drying, melt injection, extrusion, coacervation, and emulsification. The materials used in nanoencapsulation include lipids, proteins, carbohydrates, cellulose, gums, and food grade polymers. Applications and benefits of nanoencapsulation such as controlled release, protections, and taste masking will be explained in detail. Includes the most up-to-date information on nanoencapsulation and nanocontainer-based delivery of antimicrobials Presents nanomaterials for innovation based on scientific advancements in the field Provides control release strategies to enhance bioactivity, including methods and techniques for research and innovation Provides useful tools to improve the delivery of bioactive molecules and living cells into foods

This book was released on 2013-04-17 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grapevine is one of the major cultivated plant crops. As with most woody plant species, molecular biology and biotechnology have progressed at a slow pace, due to several obstacles which have had to be overcome. However, substantial progress has now been made and useful information has been accumulated in the literature; numerous genes have been characterized from grapevine and significant progress has been made in the molecular and non-molecular biotechnological applications. In an effort to collect and present the state of the art on grapevine molecular biology and biotechnology, 41 scientists from 12 countries worked jointly on the preparation of this book. It is intended as a reference book for viticulturists, graduate and undergraduate students, biotechnological companies, and any scientist who is interested in molecular biology and biotechnology of plants with emphasis on grapevine.

Book excerpt: Wood adhesives are of tremendous industrial importance, as more than two-thirds of wood products in the world today are completely or partially bonded together using a variety of adhesives. Adhesive bonding offers many advantages over other joining methods for wood components, and there has been a great deal of R& D activity in devising new wood adhesives or improving the existing ones. The modern mantra in all industrial sectors is: "think green, go green," which has attracted much attention in the wood adhesive industry. Therefore, there is also a lot of research activity in synthesizing environmentally benign and human-friendly wood adhesives. This book is divided into four parts: Part 1: Fundamental Adhesion Aspects in Wood Bonding; Part 2: Synthetic Adhesives; Part 3: Environment-friendly adhesives; and Part 4: Wood Welding and General Paper. It addresses many different types of wood adhesives, as well as bonding (welding) of wood components without adhesives, a more recent development. The information contained in this book is valuable for individuals engaged in all aspects of wood adhesion and adhesives and, hopefully, will inspire new ideas in wood adhesives, a topic of vital industrial importance.
