This fuel form would require a considerable development effort both in fabrication and optimization of performance. The addition of bum-able poisons would probably be made directly to the Pu02, but studies would have to be performed to optimize the performance and reliability of this modified fuel form. 

Lv et al. (2009, 2013) fabricated and optimized nHA/PLGA composite scaffolds for bone regeneration. The incorporation of nHA contributed to the bioactivity of the scaffolds for osteointegration. Under in vitro culture condition, human mesenchymal stem cells (hMSCs) expressed elevated expression of phenotypic markers such as alkaline phosphatase as well as mineral deposition on the composite scaffolds as compared to PLGA scaffolds.

The crystal quality of the InGaN QWs becomes poor mainly due to the lattice-constant mismatch and the difference of the thermal expansion coefficient between InN and GaN with increasing the In composition [4,5]. Therefore, in order to improve the external quantum efficiency (i/ext) of the InGaN-based LEDs and LDs, it is important to elucidate and optimize the effects of the various growth conditions for the InGaN active layer on the structural and optical properties. Recently, we reported a fabrication of efficient blue LEDs with InGaN/GaN triangular shaped QWs and obtained a substantial improvement of electrical and optical properties of the devices [6,7]. 

In this chapter the technological development in cathode materials, particularly the advances being made in the material s composition, fabrication, microstructure optimization, electrocatalytic activity, and stability of perovskite-based cathodes will be reviewed. The emphasis will be on the defect structure, conductivity, thermal expansion coefficient, and electrocatalytic activity of the extensively studied man-ganite-, cobaltite-, and ferrite-based perovskites. Alterative mixed ionic and electronic conducting perovskite-related oxides are discussed in relation to their potential application as cathodes for ITSOFCs. The interfacial reaction and compatibility of the perovskite-based cathode materials with electrolyte and metallic interconnect is also examined. Finally the degradation and performance stability of cathodes under SOFC operating conditions are described.
