Silicone

2020
Silicone is an open-source Python package which infers anthropogenic emissions of missing species based on other known emissions. For example, it can infer nitrous oxide emissions in one scenario based on carbon dioxide emissions from that scenario plus the relationship between nitrous oxide and carbon dioxide emissions in other scenarios.

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 XUV optical applications

SPIE Proceedings, 1991
Si/Si02 and Si/Si3N4 multilayers have been fabricated using a locally made reactive diode if-sputtering systern. 'Ihe layer alternation is obtained by modulating a partial pressure of oxygen or nitrogen near the sample using a silicon target and argon as sputtering gas.

Silicon, Silicone, and Breast Implants

Pediatrics, 2002
To the Editor .— More than 200 000 breast implant augmentation procedures have been performed annually in the United States in recent years, most on teenagers and young women of reproductive age.1 As a result, many nursing mothers have breast implants—all composed at least in part of silicone.

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

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 ...

Copper in silicon

Physical Review Letters, 1990
The presence of Cu atoms in p-type Si is detected via their characteristic electric-field gradients measured at the radioactive acceptor $^{111}\mathrm{In}$${/}^{111}$Cd by the perturbed \ensuremath{\gamma}\ensuremath{\gamma} angular correlation technique.

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.

Local Oscillations of Silicon–Silicon Bonds in Silicon Nitride

Technical Physics Letters, 2018
Raman spectra of films of nearly stoichiometric amorphous silicon nitride (a-Si3N4) reveal a contribution due to local oscillations of silicon–silicon (Si–Si) bonds. This observation directly confirms that the almost stoichiometric a-Si3N4 contains Si–Si bonds, which, according to theoretical predictions, act as electron and hole traps that are ...
