    Notizen: The various materials used in biomedical applications, viz., metals and alloys, polymers, ceramics, and composites, are reviewed, and their respective areas of application discussed. Problems of compatibility with tissue and body fluids are reviewed and the performance of the various materials systems examined. Some examples of failure of implanted devices are shown, and the need for careful control of quality as well as of material specification is emphasized. Finally, the importance of close cooperation between medical, engineering and metallurgical specialists in this area is noted, together with the requirement of a better knowledge of materials on the part of the surgical personnel involved.

    Notizen: A thermal conductivity measuring apparatus that uses heat flow sensors to measure the heat flux through samples was constructed of inexpensive materials. This device was used to measure the thermal conductivity (k) of two composites used in the space program that consist of fibrous or granular components embedded in a resin matrix. The k-values that were determined ranged from 0.035 to 0.059 Btu/h-ft2-°F/ft (-163 to 553°F) and 0.029 to 0.035 Btu/h-ft2-°F/ft (77 to 212°F). Thermal conductivity values of the composites conformed to the rule of mixture. The accuracy of the system was found to be comparable to the guarded hotplate and it requires neither a skilled operator nor extensive maintenance.
