Through their incorporation as monodisperse segments into synthetic polymers we learned in recent years how to program the structure formation of polymers, to adjust and exploit interactions in such polymers, to control inorganic organic interfaces in fiber composites and induce structure in biomacromolecules like DNA for biomedical applications.
The study of cell-scaffold or growth factor-scaffold composites in vitro and induced tissue and organ regeneration in vivo have been advanced by the development and extensive use three-dimensional porous biomaterials scaffold.
However, numerous studies indicated that various components of the resin composites, like BisGMA, UDMA, and TEGDMA, may be released from composite into the oral environment and induced a variety of adverse biologic effects (Geurtsen 1998; Bouillaguet 2004).
nHA and nHA PLGA composites successfully induced osteogenic differentiation for hMSCs without the addition of osteogenic factors, achieving osteogenic differentiation comparable to that of directly adding BMP-7-derived short peptide (DIF-7c) into the culture medium.
Hygrothermal effects in composites are induced by temperature and moisture concentration.
The deformation behavior and fracture mechanism indicate that the ultrahigh compressive strength and large plasticity of the as-fabricated equiaxed composites is induced by dislocations pinning effect of the CoTi2 or (Cu,Ni Ti2 second phases and the interaction and multiplication of generated shear bands in the ductile β-Ti matrix, respectively.
The composites induced statistically and clinically significant acceleration of complete wound closure (21 ± 1 day versus 23 ± 1 day and 26 ± 1 day for DNIC-Col, Col and SpWH, respectively).
The results reveal that the different ratios of Y and Beta zeolites in the composites induced the change of surface areas, pore diameters and acid properties of HS-FBZ, and the extended Beta layers on the zeolite Y surface were observed.
The tolerance of composites to damage induced by cyclic loading and moisture ingress is of utmost importance.
The major focus was to understand the failure mechanisms of composites induced by stress concentrations, and to determine the effects of ply orientations, material properties and geometry on the fatigue damage.
