Bone Substitute Fabrication Based on Dissolution-Precipitation Reactions
Although blockor granular-type sintered hydroxyapatite are known to show excellent tissue responses and good osteoconductivity, apatite powder elicits inflammatory response. For the fabrication of hydroxyapatite block or granules, sintering is commonly employed. However, the inorganic component of bone and tooth is not high crystalline hydroxyapatite but low crystalline B-type carbonate apatite...
متن کاملDeformation-resembling microstructure created by fluid-mediated dissolution–precipitation reactions
Deformation microstructures are widely used for reconstructing tectono-metamorphic events recorded in rocks. In crustal settings deformation is often accompanied and/or succeeded by fluid infiltration and dissolution-precipitation reactions. However, the microstructural consequences of dissolution-precipitation in minerals have not been investigated experimentally. Here we conducted experiments...
متن کاملFabrication of carbonate apatite block based on internal dissolution-precipitation reaction of dicalcium phosphate and calcium carbonate.
In this study, we investigated a novel method for fabrication of carbonate apatite block without ionic movement between precursor and solution by using precursor that includes all constituent ions of carbonate apatite. A powder mixture prepared from dicalcium phosphate anhydrous and calcite at appropriate Ca/P ratios (1.5, 1.67, and 1.8) was used as starting material. For preparation of specime...
متن کاملDiffusion Controlled Dissolution and Precipitation*
Dissolution and precipitation reactions that occur in biological systems and in non-stirred in vitro systems generally are diffusion-controlled. Subsurface demineralization of tooth enamel in dental caries, which has been the subject of considerable interest, is an example of such processes. In the caries process ions from solubilized tooth mineral, i. e., Ca, P04, and OH, need to be transporte...
متن کاملFabrication of Nanoparticles of Silymarin, Hesperetin and Glibenclamide by Evaporative Precipitation of Nanosuspension for Fast Dissolution
Evaporative precipitation of nanosuspension (EPN) was used to prepare nanoparticles of poorly water soluble drugs, namely silymarin (SLM), hesperetin (HSP) and glibenclamide (GLB), with the aim of improving their rate of dissolution. The original drugs and EPN prepared drug nanoparticles were characterized by scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and dissol...
