Development and characterization of bioceramic coatings for medicall and dental applications

Mudenda, Steven January 2007 (has links)
>Magister Scientiae - MSc / Hydroxyapatite (HA), which is a natural component of bone tissue, is already being marketed as a coating for the metal shafts of hip implants as well as dental screws and other endoprostheses with the expectation of improved bonding to bone through osseointegration. Coatings prepared by the more widely used and commercial method, plasma spraying technique suffer from poor adhesion or delamination from the substrate. The high temperatures also results in a number of unstable decomposition phases compared to the more crystalline phase. The main purpose of the present research was to prepare and characterize HA coatings using low temperature sol-gel method with the specific aims of improving adhesion on both the HA/metal and HA/bone interface which have been reported failure modes of implants. / South Africa

Hydroxide binding equilibrium in hemerythrin

McCallum, John David 01 January 1982 (has links)
The measurement of the equilibrium constant and the thermodynamic parameters of the binding of hydroxide ions to the active site of hemerythrin, an invertebrate iron containing protein, was done by a new difference spectroscopic method. The method enables accurate measurements of equilibrium constants without accurate knowledge of molar absorptivities or protein concentrations and is novel in that it takes the difference between the two equilibrium mixtures, thus enabling the measurement of equilibrium constants when it is not convenient or possible to produce either substance as a pure reference material.

Layered Double Hydroxides as Anion- and Cation-Exchanging Materials

Richardson, Mickey Charles 05 1900 (has links)
Layered double hydroxides (LDH) have been principally known as anion-exchanging, clay-like materials for several decades, and continues to be the main driving force for current and future research. The chemical interactions of LDH, with transition metallocyanides, have been a popular topic of investigation for many years, partly due to the use of powder x-ray diffraction and infrared spectroscopy as the main characterization tools. Each transition metallocyanide has a characteristic infrared stretching frequency that can be easily observed, and their respective sizes can be observed while intercalated within the interlayer of the LDH. The ability of LDH to incorporate metal cations or any ions/molecules/complexes, that have a postive charge, have not been previously investigated, mainly due to the chemical and physical nature of LDH. The possibility of cationic incorporation with LDH would most likely occur by surface adsorption, lattice metal replacement, or by intercalation into the LDH interlayers. Although infrared spectroscopy finds it main use through the identification of the anions incorporated with LDH, it can also be used to study and identify the various active and inactive bending and stretching modes that the metal hydroxide layers have.
