Bioactive ceramic-reinforced composites for bone augmentation [PDF]

, 2010
Biomaterials have been used to repair the human body for millennia, but it is only since the 1970s that man-made composites have been used. Hydroxyapatite (HA)-reinforced polyethylene (PE) is the first of the ‘second-generation’ biomaterials that have ...

Bio-inspired mineral growth on porous spherulitic textured poly(L-lactic acid)/bioactive glass composite scaffolds [PDF]

, 2008
It has been shown that texture can strongly influence the adhesion, orientation and proliferation of cells onto the surface of biomaterials. Additionally, it is possible to imprint micrometer level textures throughout the scaffolds by melt compounding ...

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

Advanced Engineering Materials, EarlyView.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Ultrahigh electrostrain with excellent fatigue resistance in textured Nb5+-doped (Bi0.5Na0.5)TiO3-based piezoceramics

Journal of Advanced Ceramics, 2023
(Bi0.5Na0.5)TiO3 (BNT)-based lead-free piezoceramics exhibit excellent electric field-induced strain (electrostrain) properties, but often suffer from large hysteresis and poor fatigue resistance, which strongly limit their applications. Here, <00l>

Unlocking the Power of Quercetin‐Encapsulated Mesoporous Bioactive Glass Nanoparticles: A Multifunctional Approach to Bone Regeneration

Advanced Engineering Materials, EarlyView.
Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.

Recent Developments in (K, Na)NbO₃-Based Lead-Free Piezoceramics

Micromachines
(K0.5Na0.5)NbO3 (KNN)-based ceramics have been extensively investigated as replacements for Pb(Zr, Ti)O3-based ceramics. KNN-based ceramics exhibit an orthorhombic structure at room temperature and a rhombohedral–orthorhombic (R–O) phase transition ...

Crystallographic texture in ceramics and metals

Journal of Research of the National Institute of Standards and Technology, 2001
Preferred crystallographic orientation, or texture, occurs almost universally, both in natural and man-made systems. Many components and devices in electronic and magnetic systems are fabricated from materials that have crystallographic texture. With the rapidly increasing use of thin film technology, where sharp axisymmetric crystallographic texture ...
