... In this paper we examine the effect of dry etching on p-type and n-type material implanted with 11 B + at 100 keV to doses of 1E12, 1E13, 1E14, 1E15, and 1E16 cm −2 . Hydrogen-containing etch chemistries and typical etch parameters are simulated by Ion Beam Etching with 100% deuterium. We show...

... Despite earlier claims of biological stability, there is growing evidence from case histories, in vitro testing, and implant retrieval programs that poly(ethylene terephthalate) fibers experience some degradation when implanted in humans as arterial prostheses. Previously, this was of minor...

... As part of a program to evaluate a family of high-strength, high-ductility stainless steels (TRIP steels) for use in orthopedic implants, the crevice corrosion resistance of one of these steels (containing 4 percent molybdenum) was compared with the resistances of two alloys in current clinical...
