First of all, it's going to be built up, we're going to build the stuff out of silicon.

Magnesium silicide, Mg2Si, is an inorganic compound consisting of magnesium and silicon.

Silicon nitride has a negligible etch rate in TMAH the etch rate for silicon dioxide in TMAH varies with the quality of the film, but is generally on the order of 0.1 nm minute.

Maybe my speeds and feeds were set up for high speed steel drill but I've got a carbide drill in the machine

Dragon Skin, which is produced by Pinnacle Armor, uses disks of silicon carbide.

He is now a partner at Kleiner Perkins, a leading venture capital firm in Silicon Valley.

If you have silicon, if you have a mole of silicon, a mole of silicon will have a mass I don't want to say weight because this should apply to any planet of 28 grams.

In her doctoral research at Berkeley, she explored the physics of chemical reactions involving silicon.

Solar cells make use of the particular characteristic of silicon to emit a small quantity of electricity when struck by sunlight.

The central part of an atom, made up of tightly packed pro tons and neutrons.

Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth's crust.

The tested soil contained abundant silicon and iron, along with significant amounts of magnesium, aluminum, sulfur, calcium, and titanium.

The weight ratio of iron to silicon is 1.05 1.27 in Ganymede, whereas the solar ratio is around 1.8.

It is mostly composed of iron, oxygen, silicon, zirconium and titanium with smaller fractions of yttrium and calcium.

It is mostly composed of iron, silicon and oxygen, with smaller fractions of calcium and several other metals.

The silicon reacts with the graphite in the carbon carbon composite to become carbon fiber reinforced silicon carbide (C SiC).

And it was during this time that there was increased calcium and iron and silicon in the environment, and organisms learned how to make hard materials.

It was during this time that there was increased calcium, iron and silicon in the environment, and organisms learned how to make hard materials.

The master template fabricated by Idaho National Laboratories consists of approximately 10 billion antenna elements on an 8 inch round silicon wafer.

After a proof of concept on a stiff silicon substrate, the experiment was replicated on a flexible polymer based substrate.

Silicon technology has advanced greatly In recent years, improving the efficiency of solar panels and reducing their cost.

Indian children inhale large doses of sulphur and potassium chlorate to fashion flammable powder into matches. Youthful glassmakers in Brazil breathe toxic silicone and arsenic fumes.

Superconductivity has been detected in 3C SiC Al, 3C SiC B and 6H SiC B at the same temperature of 1.5 K. A crucial difference is however observed for the magnetic field behavior between aluminium and boron doping SiC Al is type II, same as Si B.

Bray wrote That was the one aspect that we missed, but even had we understood the idea of minority carrier injection...we would have said, 'Oh, this explains our effects.

Silicon, in contrast, interacts with only a few other atoms, and the large silicon molecules are monotonous compared with the combinatorial universe of organic macromolecules.

Activ Solar GmbH, headquartered in Vienna, Austria is engaged in the production of polycrystalline silicon (polysilicon) for the solar PV industry and the development of large scale photovoltaic power stations.

But with a suitable pair of organic substituents in place of hydrogen on each silicon it is possible to prepare polysilanes (sometimes, erroneously called polysilenes) that are analogues of alkanes.

Steel is an alloy of iron and carbon containing less than 2 per cent of carbon and 1 per cent of manganese (and small amounts of silicon, phosphorous, sulphur and oxygen).

They can be regarded as consisting of layers of silicon and nitrogen atoms in the sequence ABAB... or ABCDABCD... in β and α , respectively.

Recording experimental Kikuchi patterns and maps The figure at left shows the Kikuchi lines leading to a silicon zone, taken with the beam direction approximately 7.9 away from the zone along the (004) Kikuchi band.

So which means that it's really impossible to find an object where you find about 10 times more sulfur than silicon, five times more calcium than oxygen. It's just impossible.

Meanwhile, the human body consists of 65 oxygen, 18 carbon, 10 hydrogen, and 7 of various other elements including 0.002 of silicon.

It is composed mostly of iron (32.1 ), oxygen (30.1 ), silicon (15.1 ), magnesium (13.9 ), sulfur (2.9 ), nickel (1.8 ), calcium (1.5 ), and aluminium (1.4 ), with the remaining 1.2 consisting of trace amounts of other elements.
