Title of Speech: Development of Hydroxyapatite-Bioglass composite bioceramics scaffold for implant application 

Abstract: In a current research project extremely low pressure Spark plasma sintering (SPS) has been employed to develop mechanically stable composite scaffold materials with considerable porosity in Hydroxyapatite and Bioglass® system, with the aim to avoid excessive reactions between the constituents and crystallization of Bioglass®. The ability to avoid excessive reactions between the constituents and crystallization is very critical, as crystallized Bioglass® does not exhibit the characteristic of high biocompatibility and the reaction between the constituents yield undesired new products. SPS is a non-conventional sintering technique which can consolidate samples at lower pressures and temperatures in a shorter time period, compared to the conventional powder processing routes. These less severe processing parameters provide an opportunity to control the mechanical stability, crystallization tendency and grain size of the bioceramics and their composites. The optimized processing parameters during SPS could achieve the above-mentioned targets which is a novel development. Physico-mechanical characterization, in vitro bioactivity analyses and in vitro biocompatibility analyses have been carried out to analyze the impact of the processing conditions on the final characteristics of the scaffold materials. This novel development has yielded promising bioactivity and biocompatibility results suggesting that SPS has a great potential to improve the biological performance of Hydroxyapatite-Bioglass composite bioceramics.

Title of Speech: Nano-crystallization mechanism of BaO-Na2O-Nb2O5-SiO2-B2O3 glass; critical size, growth rate and strain effect 

Abstract: Crystallization of a glass is one of the ways to produce various types of composite materials such as secondary glass, mixture of glass-ceramics/metals, ceramics/metals and nano crystals, which can reveal different physical properties. In the scientific point of view, understanding the crystallization process from a glass is important and useful because it enables us to control the composite production specifications of crystal size, crystallinity, crystal structure, and crystal volume fraction in the glass. In this work, BaO-Na2O–Nb2O5–SiO2–B2O3 glass was synthesized by rapidly quenching the melt. Measurements of thermal, structural, local vibrational and surface properties have been analyzed by applying the models of Williamson-Hall plot, Johnson-Mehl-Avrami-Kolmogorov function and isoconversion method, to investigate the crystallization kinetics.

Title of Speech: Application of Digital Image Correlation to Test Composite Materials 

Abstract: Digital Image Correlation (DIC) is a noncontact full-field optical method for measuring displacements in experimental testing, based on the correlation of object images taken before and after deformed. It has been used in several fields of experimental mechanics. Recently, the application of DIC to the characterization of composite materials is widely expanded. Dental composites are light-curable resin-based materials with an inherent defect of polymerization shrinkage which may cause tooth deflection and debonding of restorations. The shrinkage behaviors of dental composites under four different light curing regimens were investigated by using digital image correlation (DIC) method. The shrinkage in unbonded and bonded restorations are compared. The effect of curing direction and light intensity on the shrinkage were compared. The results may provide useful information for clinical usage, and further stress analysis by numerical methods. Bonding process is frequently used in the composite structure. However, the occasional occurrence of weaker bonds in the adhesive bonded composites may cause catastrophic failure of the composite structure. Therefore an infrared image correlation method was developed to assess the strength of bonded composites by tensile testing. Using step heating thermography, the IR images of composites are obtained under various loads. Utilizing the natural feature of IR image of bonded composites, the deformation at the bonding area were determined by (DIC). Test specimens with artificial defects of Teflon and various combination of hardener/adhesive were made. With proper filtering process, sub image size, and IR image, the deformation at the bonding areas determined experimentally were compared to the results obtained using ordinary light DIC. Test results will be shown and discussed.
