Structured zeolite/silicon carbide composites were succesfully synthesized by ZSM-5 coatings deposited on macroscopic â-SiC foams with medium surface area. A homogeneous coverage of the support (30 wt % zeolite) by ZSM-5 crystals, having 1 ím average size, was reached after a double-coating procedure. The ZSM-5/â-SiC composite materials were characterized by BET, XRD, SEM, and H/D exchange methods. 27Al MAS NMR analysis revealed that all aluminum was present in a tetrahedral coordination, thus sitting in the zeolite framework. The existence of a nanoscopic layer of silica and silicon oxycarbide on the surface of the support ensures the strong anchoring of the …

The Evaluation Of Polysulfone Composites As Structural Implants In Orthopaedic Surgery, Howard L. Scalzo
Theses
Two polysulfone composites were evaluated to determine their use as structural implants in orthopaedic surgery. The first composite, carbon fiber reinforced polysulfone (C/PS), was evaluated for environmental degradation in an in vivo and in vitro study. The C/PS composites were implanted subcutaneously in the abdomen of rabbits for the in vivo study and immersed in saline solution at 32° C for the in vitro study. The second composite, hydroxylapatite coated polysulfone (HA/PS), was evaluated for bone ingrowth in an in vivo study, and for attachment strength between the HA and the PS in an in vitro study. Also, two surface …
