Synopsis Adsorption on and Surface Chemistry of Hydroxyapatite by : Dwarika N. Misra
Hydroxyapatite is the structural prototype of the main inorganic constituent of bone and teeth and, together with fluorapatite, is also one of the principal minerals in commercial phosphate ores. The adsorption characteristics and surface chemistry of hydroxyapatite are important in understanding the growth, dissolution and adhesion mechanisms of bone and tooth tissues and in elucidating the factors in mineral beneficiation such as floation and flocculation. This volume essentially documents the proceedings of the symposium on the same topic held at the American Chemical Society Meeting in Kansas City, MO, September 12-17, 1982. It includes a few papers which were not presented at the symposium but does not comprise the entire program. This volume provides, on a limited scale, a multidisciplinary overview of current work in the field of adsorptive behavior and surface chemistry of hydroxyapatite and includes certain review articles. There are two papers each on adsorption, adsorption and its effects on crystal growth or dissolution kinetics, effects of electrochemical parameters on solubility and adsorption, and newer physical methods (exoemission and high-resolution NMR) of examining hydroxyapatite surface. There is one paper each on structure modelling of apatite surface based on octacalcium phosphate interface and on biodegradation of sintered hydroxyapatite.

Synopsis Force Field Parameters and Atomistic Surface Models for Hydroxyapatite and Analysis of Biomolecular Adsorption at Aqueous Interfaces by : Tzu-Jen Lin
Biomineralization of human bone and teeth are highly associated with interactions between biomolecules and hydroxyapatite (HAP). Available force fields require specific mixing rules to describe HAP interactions with biomolecules and lack validation of polarity, interfacial interactions, as well as surface chemistry. We present a new force field for HAP which is fully integrated into the polymer consistent force field (PCFF), CHARMM, and AMBER. In addition, models of hydrated HAP surfaces are critical under physiological conditions and have rarely been addressed in previous simulation studies. The proposed force field parameters and surface models of HAP are validated by lattice structures from X-ray studies, IR spectrum, elastic constants, cleavage energies, and immersion energies in water from measurements. The validation shows substantial improvements in accuracy compared to previous models, including small deviations in cell parameters, elastic constants, and full consistency with known data on surface and immersion energies for monohydroxylated and dihydroxylated surfaces. We propose models for {001}, {010}, {020}, and {101} surfaces based on stoichiometric hydration reactions that are tunable according to pH. The protonated surface models were further tested to analyze interactions with a known HAP binding peptide, SVSVGGK, which showed attraction to {001}, {010}, and {020} surfaces and less attraction to {101} surfaces. The binding is mediated by interactions of ammonium groups on the K side chain and at the N terminus with superficial monohydrogen phosphate groups in agreement with NMR studies, as well as by coordination of superficial calcium ions by the C terminus. Furthermore, three bisphosphonate molecules used for osteoporosis, pamidronate, ibandronate, and zoledronate, were also tested on protonated {001}, {010}, {020}, and {101} surfaces corresponding to pH 5. The P-C-P motif of bisphosphonates interacts with the protonated phosphate by hydrogen bonding or coordinates with the remaining calcium on the surface. The charged nitrogen group in the pamidronate and ibandronate did not show preference the surface due to their hydrophilic side chains, but the imidazolium ring in zoledronate was pushed toward to the surface due to its hydrophobic character. The observation from the zoledronate could correlate its longer retention time found in experimental studies and HAP chromatography.

Synopsis Structure and Chemistry of the Apatites and Other Calcium Orthophosphates by : J.C. Elliott
The apatites and related calcium phosphates have been of considerable interest to biologists, mineralogists, and inorganic and industrial chemists for many years. This book contains a detailed description of the structures and structural interrelationships of the calcium orthophosphates, including the apatites. Their preparation, crystal growth and dissolution, chemical reactions including thermal decomposition, IR, Raman and NMR spectra and various physical properties are discussed. Apatites other than those containing calcium and phosphorus are included. Synthetic, mineral and biological carbonate apatites are also considered. A wide, but critical coverage of the literature is given, which includes a substantial amount not written in English. Research from many disciplines is included which results in a comprehensive compilation of recent work.

Synopsis Design and Applications of Hydroxyapatite-Based Catalysts by : Doan Pham Minh
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.

Synopsis Proteins at Solid-Liquid Interfaces by : Philippe Déjardin
This book opens with a description of fundamental aspects of protein adsorption to surfaces, a phenomenon that plays a key role in biotechnological applications, especially at solid-liquid interfaces. Presented here are methods for studying adsorption kinetics and conformational changes such as optical waveguide lightmode spectroscopy (OWLS). Also described are sensitive bench techniques for measuring the orientation and structure of proteins at solid-liquid interfaces, including total internal reflection ellipsometry (TIRE), dual polarisation interferometry (DPI) and time of flight - secondary ion mass spectrometry (TOF–SIMS). A model study of fibronectin at polymer surfaces is included, as are studies using microporous membranes and textiles with immobilized enzymes for large-scale applications. Biocompatibility, anti-fouling properties and surface modification to modulate the adsorption and activity of biomolecules are among the other topics addressed in this invaluable book.
