Apatites And Their Synthetic Analogues

Apatite-type minerals and their synthetic analogues are of interest of many industrial branches and scientific disciplines including material sciences, chemical industry, agriculture, geology, medicine and dentistry. This book provides a basic overview of general knowledges of this topic in order to provide the comprehensive survey from a scientific and technological perspective. The book is divided into 10 chapters, which are devoted to the structure and properties of minerals from the supergroup of apatite, experimental techniques of preparation and characterization of synthetic analogues of apatite minerals, substitution in the structure of apatite as well as utilization of these materials in wide range of common and special advanced applications in industry, material sciences and research. Additionally, the phosphate rocks, their classification, geological role, mining and beneficiation of phosphate ore, production of elemental phosphorus, phosphoric acid and fertilizers are also described. Although this book is meant for chemist, material scientist and research engineers, the individual chapters contain theoretical background, historical aspects as well as examples of synthetic and analytical methods which may be also interesting for students and non-expert readers as well.

The book represents a collection of papers presented at VI International Symposium "Biogenic - abiogenic interactions in natural and anthropogenic systems" that was held on 24-27 September 2018 in Saint Petersburg (Russia). Papers in this book cover a wide range of topics connecting with interactions between biogenic and abiogenic components in lithosphere, biosphere and technosphere. The main regarding topics are following: methods for studying the interactions between biogenic and abiogenic components; geochemistry of biogenic-abiogenic systems; biomineralization and nature-like materials and technologies; medical geology; biomineralogy and organic mineralogy; biomineral interactions in soil; biodeterioration of natural and artificial materials; biomineral interactions in extreme environment.

This book presents a wide and interdisciplinary overview of the current state of the art in the development of biomimetic materials for tissue regeneration on the basis of relevant and high-impact clinical needs. It specifically emphasizes the regeneration of bone, cartilage, and osteochondral tissues as well as soft tissues such as nerves, heart, and endocrine organs. It brings together contributions from materials scientists, biologists, and surgeons with globally recognized experience in the field of regenerative medicine. The aim of the book is to highlight the relevance of biomimetics as an elective approach for the development of new scaffolds that can direct regenerative cascade by means of chemico-physical and topological nano-cues presented to cells and biologic tissues. Particularly, the book refers to emerging concepts in synthesis processes and scaffolds inspired by nature as well as to novel approaches for smart functionalization such as the use of magnetic signaling.

The interaction between cells, tissues and biomaterial surfaces are the highlights of the book "Advances in Biomimetics". In this regard the effect of nanostructures and nanotopographies and their effect on the development of a new generation of biomaterials including advanced multifunctional scaffolds for tissue engineering are discussed. The 2 volumes contain articles that cover a wide spectrum of subject matter such as different aspects of the development of scaffolds and coatings with enhanced performance and bioactivity, including investigations of material surface-cell interactions.

A significant proportion of modern medical technology has been developed through biomimetics, which is biologically inspired by studying pre-existing functioning systems in nature. Typical biomimetically inspired biomaterials include nano-biomaterials, smart biomaterials, hybrid biomaterials, nano-biocomposites, hierarchically porous biomaterials and tissue scaffolds. This important book summarises key research in this important field.The book is divided into two parts: Part one is devoted to the biomimetics of biomaterials themselves while part two provides overviews and case studies of tissue engineering applications from a biomimetics' perspective. The book has a strong focus on cutting edge biomimetically inspired biomaterials including chitin, hydrogels, calcium phosphates, biopolymers and anti-thrombotic coatings. Since many scaffolds for skin tissue engineering are biomimetically inspired, the book also has a strong focus on the biomimetics of tissue engineering in the repair of bone, skin, cartilage, soft tissue and specific organs.With its distinguished editor and international team of contributors, Biomimetic biomaterials is a standard reference for both the biomaterials research community and clinicians involved in such areas as bone regeneration, skin tissue and wound repair. Places strong focus on cutting edge biomimetically-inspired biomaterials including chitin, hydrogels, calcium phosphates, biopolymers and anti-thrombotic coatings Provides overviews and case studies of tissue engineering applications from a biomimetics perspective Also places focus on the biomimetics of tissue engineering in the repair of bone, skin, cartilage, soft tissue and specific organs

Scientific research on tissue regeneration is increasingly becoming the most promising response to a number of disabling pathologies with huge impact on the progressively growing and ageing world population. The biomimicry of scaffolds with the target tissue is now universally considered to be a key requirement to properly instruct cells towards the restoration of physiological functioning. In this respect, the present chapter presents an overview of recent findings on biomimetic materials and devices addressed to bone and osteochondral tissues as well as soft organ regeneration. Particular focus is given to new apatite phases, including the newly discovered superparamagnetic apatite and processes to develop ceramic, polymeric and hybrid regenerative scaffolds.

Essential reference for researchers and experts in industry highlighting the rapidly growing field of hydroxyapatite-based catalysts and their application in various chemical processes. Hydroxyapatite (Ca10(PO4)6(OH)2) is the main mineral component of human and animal bones. It is largely applied in the field of biomaterials due to its biocompatibility. Recently, hydroxyapatite-based materials have especially gained a lot of attention by researchers in catalysis, as they are versatile and have shown precious properties of a good catalyst and catalyst support such as excellent ion-exchange capacity, high porosity, very low water solubility, controlled basicity/acidity, and good thermal stability at high temperatures. Design and Applications of Hydroxyapatite-Based Catalysts gives a detailed overview of the synthesis, characterization, and use of hydroxyapatite-based materials in catalysis. It covers synthetic hydroxyapatites (from pure chemicals or waste), natural apatites and materials from eggshells and animal bones. The application of hydroxyapatite-based catalysts in selective oxidation, deoxygenation, selective hydrogenation, dehydrogenation reactions, organic synthesis, as well as reforming processes and production of energy carriers is reviewed. Moreover, electrocatalysis and photocatalysis using hydroxyapatite-based materials are discussed. Kinetic and mechanism studies of various chemical pro-cesses over hydroxyapatite-based catalysts are also presented. This is the first book solely dedicated to hydroxyapatite-based materials and their use in catalysis. Covers synthesis and characterization, surface and structure studies, kinetic and mechanism aspects, and various applications in heterogeneous catalysis, electrocatalysis, and photocatalysis. Aimed at further stimulating research in the field Design and Applications of Hydroxyapatite-Based Catalysts is an indispensable source-of-information for researchers in academia and industry working in catalysis.
