Rediscovering Silicones: “Unreactive” Silicones React with Inorganic Surfaces

Langmuir, 2011
Chemical reactions of linear trimethylsilyl-terminated poly(dimethyl siloxane)s with the surfaces of oxidized silicon, titanium; aluminum, and nickel are reported.

Surface Behavior of Boronic Acid-Terminated Silicones

Langmuir, 2015
Silicone polymers, with their high flexibility, lie in a monolayer at the air–water interface as they are compressed until a critical pressure is reached, at which point multilayers are formed. Surface pressure measurements demonstrate that, in contrast,

Strained-Silicon on Silicon and Strained-Silicon on Silicon-Germanium on Silicon by Relaxed Buffer Bonding

Journal of The Electrochemical Society, 2006
We report the creation of two novel complementary metal oxide semiconductor CMOS -compatible platforms: strained-silicon onsilicon SSOS and strained-silicon on silicon-germanium on silicon SGOS . SSOS substrate has an epitaxially defined, strained-silicon layer directly on silicon wafer without an intermediate SiGe or oxide layer. SSOS is a homochemical

Silicon Photonics: silicon nitride versus silicon-on-insulator

Optical Fiber Communication Conference, 2016
Silicon photonics typically builds on a silicon-on-insulator based high-index-contrast waveguide system. Silicon nitride provides an alternative moderate-index-contrast system that is manufacturable in the same CMOS environment. This paper discusses the relative benefits of both platforms.

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.

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

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 ...

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.
