From fractographic analysis, it is clear that the effect of surface porosity dominates the rotating bending fatigue failure of porous NiTi samples.
To study the effect of surface porosity on antibiotic elution efficacy from bone cement, an in vitro elution study was designed using five different preparations of ALBC.
However, in the current study the effect of surface porosity and roughness to the conductance and "apparent" streaming current effects have not been quantitatively assessed; therefore, gap height dependence measurements have been planned as the next step of our investigations.
To investigate the effect of surface porosity on DC enrichment in vivo, GM-CSF-loaded PLG scaffolds were prepared while maintaining the surface porosity as described above.
The effect of surface porosity on in vivo DC recruitment was evaluated using the three different types of PLG scaffolds incorporating GM-CSF.
We first hypothesized that cell infiltration could be enhanced by increasing the amount of surface porosity in the scaffolds.
The decrease in the absorption rate and the consequent increase in specific gravity are considered to be the filling effect of the surface porosity due to the densification of the matrix inside the hardened cement paste.
Sixth, besides the effects of surface area and porosity, the surface properties of the metal (e.g., defects, exposed surface planes, and left stabilizer species) might also play important roles in their catalytic behavior, which is of great interest to study.
My work has been exploring the separate effects of surface roughness, wettability and porosity on both Critical Heat Flux (CHF) and quenching heat transfer (Leidenfrost point temperature).
