SILICON

Annual Review of Plant Physiology and Plant Molecular Biology, 1999
▪ Abstract  Silicon is present in plants in amounts equivalent to those of such macronutrient elements as calcium, magnesium, and phosphorus, and in grasses often at higher levels than any other inorganic constituent. Yet except for certain algae, including prominently the diatoms, and the Equisetaceae (horsetails or scouring rushes), it is not ...

Silicone emulsions

Advances in Colloid and Interface Science, 2006
Silicone polymers are a class of hybrid organic/inorganic polymers, that show desirable surface properties such as low surface energy and high flexibility, which enables even a very high molecular weight chain to achieve optimal orientation at the interface.

SILICON NANOCRYSTALS ENABLING SILICON PHOTONICS

2010
Silicon Photonics is an emerging field of research and technology, where nano-silicon can play a fundamental role. In this chapter, the main building blocks of Silicon Photonics ( waveguides, modulators, sources and detectors) are reviewed and compared to their counterparts made by Si nanocrystals.

Silicon/silicon oxide and silicon/silicon nitride multilayers for extreme ultraviolet

Optical Engineering, 1991
Si/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.

Gluing silicon with silicone

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.

Silicon-silicon interfaces

Applied Physics Letters, 1982
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

1996
Although 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

Seminars in Arthritis and Rheumatism, 1989
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.
