Abstract:

Apatite based glass-ceramics are some of the most bioactive materials found to date. They do not require fibrous encapsulation and bond to bone directly through an apatite layer. Apatite based glass-ceramics exhibit relatively poor biaxial flexural strength, hence limiting their applications to non-load bearing implants. The addition of mica results in a material that is highly machinable, and provided that a suitable interlocking microstructure can be produced, the strength will be increased. The aim of this work is to investigate how altering the heat treatment affects the crystallisation an

This particular trait along with good sintering ability and high mechanical strength make them ideal materials for scaffold fabrication.

Abstract:

Objectives: The objectives of this study were to develop model dental composites incorporating fluorapatite (FA) as secondary filler and to characterise their physical and mechanical properties and fluoride ion release. Methods: Experimental composites were formulated containing BisGMA/TEGDMA/BisEMA and barium aluminium silicate glass as the primary filler. FA rod-like crystals and bundles were synthesised using a hydrothermal method and incorporated at 0 (0FA), 10 (10FA), 20 (20FA), 30 (30FA) and 40% (40FA) by mass into the previously identified optimum experimental composite, maintaining an

Abstract:

Currently, most titanium implant coatings are made using hydroxyapatite and a plasma-spraying technique. There are however limitations associated with the plasma-spraying process including; poor adherence, high porosity and cost. An alternative - the sol-gel technique offers many potential advantages but is currently lacking research data for this application. Hydroxyapatite (HA), fluorhydroxyapatite (FHA) and fluorapatite (FA) have been synthesised by a sol-gel method. Calcium nitrate and triethyl phosphite were used as precursors under an ethanol-water based solution. Different amounts of am

Highly technological applications and scarcity of supply have inspired the recovery of rare earth elements (REEs) from various resources. Many rare earth phosphate mineral concentrates are associated with fluorapatite (FAP).

Abstract:

Dental enamel is an excellent example of a highly mineralised tissue, composed of hierarchically organised apatite mineral. This unique organisation gives enamel superior mechanical properties. However, when mature, enamel becomes acellular and unable to repair itself during traumatic or carious damage. The lack of self-repair requires dental intervention, where the common treatment of decayed enamel is to remove the affected and healthy tissue, and replace with restorative materials. The restorative materials, currently used, can cause further complications in the form of secondary caries or

Accordingly, the present study replaces HA with fluorapatite (FA) as the coating material, and examines the effects of two

Fluorescence is the rapid emission of light after photon absorption. The absorption and emission characteristics of a sample depend on both the fluorescent species and the surrounding lattice. Fluorescence can thus be used to identify particular materials, even in a complicated environment. Upconversion fluorescence is a process wherein the sample absorbs one or more photons of a lower energy than the photons of fluorescence emission. Upconversion fluorescence wavelengths are much less likely to excite upconversion from multiple samples at once, which can provide greater sample specificity for

Abstract:

碩士<br>南臺科技大學<br>機械工程系<br>105<br>In this study, the fluorapatite (FA), which has higher thermal stability than hydroxyapatite (HA) was mixed as a coating material, and the Ti-6Al-4V substrate was pre-coated with a pure Ti by vacuum plasma spraying (VPS )on the Ti-6Al-4V substrate as bond coat first, and then investgate the mechanical properties and the biological properties of the graded coatings. The results show that In the case of monolayer composite coating, the thickness and porosity of all specimens are decreased with increasing power, and the decreasing proportion of FA / Ti , the coatin

Abstract:

No<br>The latest advances in mesocrystal formation and non-classical crystallization of pre-synthesised nanoparticles have been reviewed with the focus on providing a fuller description of a number of complex systems and their properties and applications through examination of the crystallisation mechanisms at work. Two main crystallization principles have been identified; classical crystallization and particle based aggregation modes of non-classical pathways. To understand the non-classical pathways classical crystallization and its basics are introduced before non-classical pathways, such a
