There's diatoms made out of SIO2, and they're magnetotactic bacteria that make small, single domain magnets used for navigation.

It is standard for a lot of ionic compounds, like CaCl2, and for macromolecules, such as SiO2.

They are also used in conjunction with silicon to produce hybrid silicon lasers.

The silicone trip

Germanium differs from silicon in that the supply for germanium is limited by the availability of exploitable sources, while the supply of silicon is only limited by production capacity since silicon comes from ordinary sand or quartz.

Silicon is also very soluble and usually forms the compound SiO2 MxOy.

Osmium tetroxide (also osmium(VIII) oxide) is the chemical compound with the formula OsO4.

Silicone oil is more commonly used in cases associated with proliferative vitreo retinopathy (PVR).

Silicone rubber pipes have been used for this purpose in UK since 1999.

The first set of tables (tables 1 and 2) covers conservativeness factors for sources included in Annex A to the Kyoto Protocol.

Now, as we breathe, we produce carbon dioxide, and that carbon dioxide needs to be scrubbed out of the system.

1 The World Health Organization recognizes six main types of air pollutants carbon monoxide, nitrogen dioxide, particulate matter, sulphur dioxide, tropospheric ozone and suspended particulate matter.

The 6507 and 6502 chips use the same underlying silicon layers, and differ only in the final metallisation layer.

1 GT (or gigatonne) CO2 equivalent means 1,000 million of tonnes of CO2.

Nitric oxide, or nitrogen oxide, also known as nitrogen monoxide, is a molecule with the chemical formula NO.

Here's an interesting one for the IT world bio silicon. This is a diatom, which is made of silicates.

It could disperse heat like brass or steel and it could conduct electricity like copper or silicon.

The mineral form of silicon carbide was named moissanite in honor of Moissan later on in his life.

The method is based on the use of well defined porous templates, such as porous aluminum or silicon.

The first three digits of the chip identifier are part of the silicon layers, and the final digit is in the metallisation layer.

Rutile is a mineral composed primarily of titanium dioxide, TiO2.

One obvious condition is mandatory CO2 sequestration (removing CO2 from the air and storing it deep underground).

In fact, maybe this experiment was the reason that Silicon Valley got off to its great start with innovation.

Besides silicon and oxygen, the most abundant elements in the Martian crust are iron, magnesium, aluminum, calcium, and potassium.
