A new procedure for the bioactivation of alumina-based porous ceramic constructs was introduced. The were built with aim mimicking structural and mechanical properties human cortical bone. Bioactivation achieved by adding wollastonite acidic surface treatment (piranha solution). Structural studies (SEM, CAT) confirmed that adequate pore size interconnectivity obtained. Uniaxial compression tests showed values Young's moduli compressive strength reduced, from 5 to 1 GPa, 45 15 MPa,...
The Taguchi method is used to optimize the manufacture of porous alumina made through reactive spark plasma sintering and carbon sacrificial template. goal design a new versatile procedure that allows fabrication with tailored physical properties. structural mechanical properties taken as target parameters were subtle combination porosity Young's modulus human cortical bone: typical pore size ¿100μm, in range 3—30 GPa. input factors are wt.% carbon, time, calcination heating rate, final heat...
In this work, a procedure for fabricating porous alumina with the use of carbon sacrificial template has been tested in order to optimize fabrication structures mimicking porosity and mechanical properties human cortical bone. Two different sources were used compared, sintering calcination routes considered. The studied by Hg porosimetry revealed that amount size shape pores are still below required values, although some acicular clearly observed SEM. Moreover, measured (Young's modulus)...
Highly porous bioceramic scaffolds are widely used as bone substitutes in many applications. However, the use of bioceramics is often limited to hard tissues due risk potential soft tissue calcification. A further limitation highly their poor mechanical stability, manifested by tendency break under stress. In our study, CaP-based were prepared via freeze-casting with longitudinal and oriented pores ranging from 10 20 μm a relative porosity ∼70%. The resulting achieved flexural strength 10.6...
Nowadays, there exists a huge interest in producing innovative, high-performance, biofunctional, and cost-efficient electrospun biomaterials based on the association of biocompatible polymers with bioactive molecules. Such materials are well-known to be promising candidates for three-dimensional biomimetic systems wound healing applications because they can mimic native skin microenvironment; however, many open questions such as interaction mechanism between dressing material remain unclear....
Abstract A Cellular Automata model has been developed to study the sintering behavior of ceramic particles. In this model, only physical rule that drives evolution system is reduce energy at interface between mass cells and void cells. The meaning several computational parameters, such as particle size or compuntational temperature, were researched. Experiments partial spherical particles silica performed it was verified successfully mimics neck formation. Moreover, other experimental...
