Available in PDF, EPUB and Kindle. Book excerpt: Hydroxyapatite coatings are of great importance in the biological and biomedical coatings fields, especially in the current era of nanotechnology and bioapplications. With a bonelike structure that promotes osseointegration, hydroxyapatite coating can be applied to otherwise bioinactive implants to make their surface bioactive, thus achieving faster healing and recovery. In addition to applications in orthopedic and dental implants, this coating can also be used in drug delivery. Hydroxyapatite Coatings for Biomedical Applications explores developments in the processing and property characterization and applications of hydroxyapatite to provide timely information for active researchers and newcomers alike. In eight carefully reviewed chapters, hydroxyapatite experts from the United States, Japan, Singapore, and China present the latest on topics ranging from deposition processes to biomedical applications in implants and drug delivery. This book discusses: Magnetron sputtering and electrochemical deposition The modification of hydroxyapatite properties by sol–gel deposition to incorporate other elements found in natural bones, such as zinc, magnesium, and fluorine The use of pure hydroxyapatite in drug delivery applications The growth or self-assembly of hydroxyapatite on shape memory alloy Hydroxyapatite composite coatings—with carbon nanotubes, titanium dioxide (TiO2), and others—on the titanium alloy Offering valuable insights and a wealth of data, including numerous tables and figures, this is a rich source of information for research on hydroxyapatite coatings. Each chapter also covers material that provides an accessible stepping stone for those who are new to the field.

This book was released on 2012-12-06 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

This book was released on 2014-04-17 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Calcium Phosphate Biomaterials presents a comprehensive, state-of-the-art review of the latest advances in developing calcium phosphate biomaterials and their applications in medicine. It covers the fundamental structures, synthesis methods, characterization methods, and the physical and chemical properties of calcium phosphate biomaterials, as well as the synthesis and properties of calcium phosphate-based biomaterials in regenerative medicine and their clinical applications. The book brings together these new concepts, mechanisms and methods in contributions by both young and “veteran” academics, clinicians, and researchers to forward the knowledge and expertise on calcium phosphate and related materials. Accordingly, the book not only covers the fundamentals but also open new avenues for meeting future challenges in research and clinical applications. Besim Ben-Nissan is a Professor of Chemistry and Forensic Science at the University of Technology, Sydney, Australia

Download or read book Structural Changes of Plasma Sprayed Hydroxyapatite Coatings During In Vitro Testing written by CC. Berndt and published by . This book was released on 1994 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The in-vitro behavior of hydroxyapatite (HAp) coatings depends on the thermal history of the coating after thermal spraying. As-sprayed amorphous coatings degrade in Ringer's solution. Heat treatment at 800 °C for 2 hours produces a crystalline coating which upon immersion in physiological solution displays a greater stability. Coatings are characterized for surface morphology, composition, crystallinity, roughness, and weight loss. The as-sprayed coating shows changes in the coating morphology with immersion time. Individual lamellae crack and separate from the coating. Those lamellae still intact show evidence of dissolution. After a period of 8 weeks small HAp spheres cover the surface of the as-sprayed and heat treated coatings. These morphological changes are expected to influence the rate of bone bonding. Therefore post-treatment of HAp coatings is seen as a technique to alter or control implant-tissue interactions.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, coatings of hydroxyapatite (HAp) prepared by thermal spraying technique are investigated for biological response. Spraying was done on two geometrically different Ti-6Al-4V alloy substrates under atmospheric conditions. Subsequent immersion experiments, mimicking physiological environment, were carried out using simulated body fluids (SBF). Non-destructive techniques utilizing conventional and high-energy synchrotron diffractometry were employed for depthaÌ22́Ơ0́−resolved investigations of phase composition, crystallinity and residual stresses within the coating for both substrate geometries. Microscopy techniques were used to examine surface morphology and microstructure. In both substrate geometries and for all immersion periods, HAp is the predominant phase with tetra-calcium phosphate (TTCP) and tri-calcium phosphate (TCP) the two main thermal products. The coating deposited on cylindrical rod substrate show a higher volume fraction of HAp at the near-surface region for the as-sprayed condition and samples immersed for 7 and 28 days. Further immersion shows the former decreasing gradually while the latter saturates after 28 days. Thermal products TTCP and TCP, for the coating deposited on the flat geometry substrate decreased with immersion, while those deposited on the cylindrical rod remains roughly the same before increasing slightly. Through-thickness behavior shows the as-sprayed HAp increasing almost linearly with depth, reaching a maximum around the coating midpoint before decreasing with further depth. Immersion in SBF does not alter the general trend across the coating however it increased the volume fraction of HAp within the first half of the coating with the biggest change occurring between 7 and 28-days of immersion. The variation of HAp with depth and immersion at the three lateral positions shows agreement within error bars indicating the coating to be homogenous. The trend is observed for coating deposited on cylindrical substrate geometry. Both substrate geometries show high near-surface region crystallinity with an index of ~90%. The interface region is less crystalline with a degree of crystallinity index of 67% and 56% for the flat and cylindrical substrates, respectively. Immersion in SBF does not alter the general through-thickness trend however it increased the degree of crystallinity at both ends. Residual stresses for the coating deposited on both substrate geometries are tensile and small, not exceeding 42 MPa and 65 MPa, respectively. The stresses are mainly confined in the near-surface region with the interior region showing neglible stresses,
