Silicon/silicon oxide and silicon/silicon nitride multilayers for extreme ultraviolet
Optical Engineering, 1991Si/SiO2 and Si/Si3N4 multilayers have been fabricated using a locally made reactive diode ri-sputtering system. The layer alternation is obtained by modulating a partial pressure of oxygen or nitrogen near the sample using a silicon target with argon as sputtering gas.

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1998
Abstract Problems and solutions concerning the gluing of silicon detectors are discussed. The R & D work for the HERA- B vertex detector system led to gluing studies with epoxy and silicone-based adhesives used on ceramics and carbon fibre. The HERA- B solution using a silicone glue is presented.

A wide variety of measurements on silicon grain boundaries shows that the electronic properties of such boundaries are much like those of Si surfaces in all essential respects. Moreover, the properties of ’’clean’’ surfaces and lightly contaminated surfaces can be studied on many crystallographic orientations of the interfaces without the need for ...

Silicon and Silicone Levels in Patients with Silicone Implants
1996Although a potential link between silicone gel breast implants and autoimmune connective tissue disease has been suggested, none has been proven. The potential role of silicone as an immune adjuvant remains very controversial. Currently available techniques do not easily allow precise measurements of silicone in tissues.

Silicone synovitis around a broken silicone elastomer finger joint implant was first described by Aptekar et al in 1974. More recently, it has become apparent that synovitis can result from abraded particles from intact prostheses, which can cause severe damage to adjacent bones and joints.

Since silicone has rapidly become one of the most commonly used prosthetic materials in the last 30 years in modern medicine, we have consequently been witnessing more silicone-related disease. Especially after silicone breast implantation, defects in the breast implant have led to serious complications, whereas complications of silicone prosthesis ...

Japanese Journal of Applied Physics, 1972
The influences of annealing at high temperatures and of impurity diffusion such as phosphorus and boron on fast surface states and instabilities under bias-temperature treatment were investigated. The fast surface states and instabilities increased by annealing in nitrogen, argon and oxygen. The instabilities were caused by the increase in conductivity

Hand Clinics, 1986
Infection has not been considered in this article with each individual implant. The incidence is low indeed. In the only publication concerned primarily with the topic of infection following silicone implant surgery, Millender et al. reviewed 2105 implants of varying kinds. There were ten infections, seven of which were with Staphylococcus aureus.

The American Journal of Medicine, 1975
A patient with excessive industrial exposure to silicon and an elevated silicon content in his renal tissue was found to have a distinctive nephropathy, characterized pathologically by changes in the glomeruli and proximal tubules, and manifested clinically by albuminuria and hypertension. Proximal tubular function was intact.

Migration of ventriculoperitoneal shunt catheters, although infrequent, is well reported. We report the unusual event of a patient who, after having had three shunt revisions over a 15-year period, presented with a per-oral extrusion of her original distal catheter.
