what is silicon what is silicon Name Origin Latin silex, or silicis (meaning what were more generally termed "the flints" or "hard rocks" during the Early Modern era where nowadays we would say "silica" or "silicates") "Silicon" in different languages. Sources Silicon is the second most abundant element and comprises 25.7% of the earth's crust (oxygen is first). Makes up major portion of clay, granite, feldspar, mica, asbestos, quartz (SiO2), and sand. Primary producers are Austria, Italy, India, South Africa, Australia, Canada, the USA and Brazil. Every year around 5000 tons of electronics grade silicon is produced. Abundance Universe: 700 ppm (by weight) Sun: 900 ppm (by weight) Carbonaceous meteorite: 1.4 x 105 ppm Earth's Crust: 2.771 x 105 ppm Seawater: Atlantic surface: 0.03 ppm Atlantic deep: 0.82 ppm Pacific surface: 0.03 ppm Pacific deep: 4.09 ppm Human: 260000 ppb by weight 58000 ppb by atoms Uses Used in glass as silicon dioxide (SiO2). It is used as a semiconductor to make microchips for electronics (like your computer). Silicon is also used in solar cells, tools, cement, LCDs, grease and oils. History Silicon (Latin silex, silicis for flint, flint's) was first identified by Antoine Lavoisier in 1787, and was later mistaken by Humphry Davy in 1800 for a compound. In 1811 Gay-Lussac and Thenard probably prepared impure amorphous silicon through the heating of potassium with silicon tetrafluoride. In 1824, Berzelius prepared amorphous silicon using approximately the same method ...

Planet Vulcan: Toxic Oasis Check out this animation from the Kepler space telescope portraying a dramatic planetary discovery. Kepler-10b, it's called, orbits its sun at a distance more than 20 times closer than Mercury is to our Sun. The daytime temperature is more than 2500 degrees Fahrenheit. Intense radiation from the star has stripped it of any atmosphere. Instead, the planet's molten surface throws off a strange kind of haze... flecks of silicates and iron swept away by stellar radiation, much like a comet's tail when its orbit brings it close to the Sun. Call this hot world Vulcan... after the Roman god of fire. We can only imagine what it's like down on the surface. The gravitational twisting and tugging from the parent star have likely endowed its rocky surface with lakes and rivers of lava. It's not a place for us ever to visit. Rather, this toxic oasis is merely another point on a grand map, whose roads are light beams crisscrossing the galaxy.
Silicate Salts, A Crystal Garden Using sodium silicate solution many different metal silicate shapes can be grown. Saturated sodium silicate solution is added to a beaker which has a transition metal salt in it. Interesting patterns grown out from the salt as metal silicates are formed.
Ultramafic Nickel Ore Flotation - 1 Ultramafics are one of the three major sources of Nickel. The other two are sulphides and laterites. Because of decreasing sulphide ore sources and the cost of treating laterites, increasing attention is directed to the third source, Ultramafic ores. A huge Nickel resource in Ultramafic hosted rocks are available in 'Thompson Nickel Belt' located in north central Manitoba. Similar ore bodies in a considerable amount have also been reported to be existed in Quebec, Western Australia, North Central China and Zimbabwe. The major processing challenge is posed by the serpentine polymorph chrysotile, the dominant part of this ore. Being fibrous in nature, chrysotile creates physical entanglement which in turn reduces selectivity and hinders bubble motion during flotation. In this video you can compare the froth phase of a common sulphide ore to the Ultramafic one. Froth phase seems lack of shiny sulphide particles in case of Ultramafic ore reveals no separation between sulphides and silicates.
Island of Terror - Silicates Diorama This is a video of a diorama of The classic British movie Island of Terror starring Peter Cushing and Edward Judd. I was contacted by a customer that wanted this diorama because he loved "B" movies - so do I!! I have done a similar one for Day of the Triffids for him, so this one just falls into place. If you have some ideas in mind, just email me at propdept@. I can make the diorama bigger, smaller, and even with sound effects. Enjoy the Video!!!
Zycosoil - Capillary Rise Demonstration - Soil This video demonstrates the effect Zycosoil treatment has on soils and sands containing silicates in preventing water absorption and infiltration. Treated materials will not absorb water, thus you see a beading effect when water is placed onto the pile of material. You also will see that capillary rise of water into the soil or sand is prevented after Zycosil treatment, as demonstrated by the untreated pile rapidly absorbing water added to the dish and becoming much darker in color.

Icy Organics in Planet-Forming Discs Using the Spitzer Space Telescope, astronomers are probing the chemistry of circumstellar discs, the dusty discs that surround stars, to understand the first moments in planetary life. Spitzer has turned its ultra-sensitive infrared spectrograph instrument toward five young stars in the constellation Taurus. These stars are still surrounded by thick, dusty discs -- relics of the gravitational collapse that formed them only a few million years ago. The five discs have similar chemistry, indicating dusty material rich in silicates and organic compounds, as well as both water and carbon dioxide ices. Despite their similarities, there are also intriguing differences between the discs that may hold important clues about the evolution of stars and their young planetary systems. In this animation, we focus on the disc of a young star. Light from the star is almost completely blocked by the thick dust and is seen only when it scatters off dust and gas above the disc plane. Delving in closer, we observe that the disc is composed of countless tiny grains of dust, some of which, according to Spitzer observations, have crystal structures. These dust grains may serve as the first building blocks of new planets, accreting into larger and larger bodies, as time progresses. As a few of these crystals fill our view, a strange metamorphosis takes place. Ice, already known to be present in these discs, begins to condense onto the surface of the crystals. Over time, the grains become larger ...
Zycosoil - Water Permeability Illustration - Sand This video demonstrates the dramatic improvement which soil or sand treated with Zycosoil exhibits in resistance to water infiltration. You will see that untreated material readily absorbs water, becoming darker in color as it wets out. Water applied to treated material sits on top of the material, and when poured off you will see that the material remains dry.

A chemical garden I followed Nurdrages instructions to make sodium silicate (roughly) and to my surprise, I did not fail; so I quickly got the camcorder out and filmed crystals growing. This explains the crap background, lack of video method, and general bad quality. To make the sodium silicate ('liquid glass'), please follow Nurdage's method in this video: You don't need to use the exact amounts of silicates or sodium hydroxide, all you are aiming to make is a fairly concentrated solution of sodium silicate. The way this experiment works is by (transition) metal silicates forming from the metal salts you place in the sodium silicate solution. The repeated bursting (due to osmotic pressure) and reformation of the metal silicates 'membranes' causes the crystals to grow, upwards due to the density of the sodium silicate solution. The salts I used were: copper sulphate, Iron sulphate, cobalt chloride I also put some cobalt ferro-cyanide which i decided to quickly make on the spot, this unfortunately failed and ended up as the mushroom/squid like thing you can see floating around at the end of the video. For more information on this experiment, please refer to Nurdrage's channel or this: Subscribe, rate and comment! =-]
Jupiter's Moon: Callisto Rotation Callisto (pronounced /kəˈlɪstoʊ/,or as Greek Καλλιστώ) is a moon of the planet Jupiter, discovered in 1610 by Galileo Galilei. It is the third-largest moon in the Solar System and the second largest in the Jovian system, after Ganymede. Callisto has about 99% the diameter of the planet Mercury but only about a third of its mass. It is the fourth Galilean moon of Jupiter by distance, with an orbital radius of about 1 880 000 km. It does not form part of the orbital resonance that affects three inner Galilean satellites—Io, Europa and Ganymede—and thus does not experience appreciable tidal heating. Callisto rotates synchronously with its orbital period, so the same face is always turned toward Jupiter. Callisto's surface is less affected by Jupiter's magnetosphere than the other inner satellites because it orbits farther away. Callisto is composed of approximately equal amounts of rock and ices, with a mean density of about 1.83 g/cm3. Compounds detected spectrally on the surface include water ice, carbon dioxide, silicates, and organic compounds. Investigation by the Galileo spacecraft revealed that Callisto may have a small silicate core and possibly a subsurface ocean of liquid water at depths greater than 100 km. The surface of Callisto is heavily cratered and extremely old. It does not show any signatures of subsurface processes such as plate tectonics, earthquakes or volcanoes, and is thought to have evolved predominantly under the influence of impacts. Prominent ...
80 gallon reef tank aquarium Hi. just wanted to show what a simple reef or marine tank would be like. It doesn't have to be complex and expensive. All i do myself is top off the water level with ro/di water, change 10% each week or 20 % every 2 weeks and feed your fish. there are a few other minor things i do every 3 months but not much. thanks
Silicate Crystal Formation in the Disk of an Erupting Star [720p] This artist's concept illustrates how silicate crystals like those found in comets can be created by an outburst from a growing star. The image shows a young sun-like star encircled by its planet-forming disk of gas and dust. The silicate that makes up most of the dust would have begun as non-crystallized, amorphous particles. Streams of material are seen spiraling from the disk onto the star increasing its mass and causing the star to brighten and heat up dramatically. The outburst causes temperatures to rise in the star's surrounding disk. The animation (figure 1) zooms into the disk to show close-ups of silicate particles. When the disk warms from the star's outburst, the amorphous particles of silicate melt. As they cool off, they transform into forsterite (figure 2), a type of silicate crystal often found in comets in our solar system. In April 2008, NASA's Spitzer Space Telescope detected evidence of this process taking place on the disk of a young sun-like star called EX Lupi.

Diesel Decaf Diesels have a reputation for being dirty and smelly, releasing clouds of soot loaded with ash, carbon monoxide, and silicates into the air. But Volkswagen claims TDI Clean Diesels are different, removing over 95% of these harmful particles from their exhaust. But can a diesel really be clean? To find out, the new Touareg TDI squared off against a traditional diesel for an unexpected comparison.
Will the Volcano Eruptions Ever End? Michio Kaku explains some of the science behind the prediction of volcanoes and if the eruptions are ever going to end. The Icelandic eruption was a perfect storm, a combination of wind and ice conditions that has turned an ordinary eruption into a crisis. Last month, the same volcano erupted harmlessly. But last week, magma found a second pathway to the surface, this time beneath a glacier. When hot magma touched ice, it instantly created a burst of steam and produced glassified silicates. The sudden expansion of steam created a colossal explosion that sent billowing clouds of glassified silica ash three to five miles into the air over Europe. The ongoing eruptions of the volcano, which continue unabated, are caused by a series of steam explosions as magma continues to encounter glacial ice.
Ron Craig asked questions by UW 9/11 Research Group Ron Craig, an explosives/special effects expert, gave a talk about whether explosives brought down the WTC towers. He argues against the controlled demolition hypothesis. Craig is asked questioned by members of the UW 9/11 Research Group. Craig is asked about the high temperatures found by RJ Lee Group since fires cannot reach such high temperatures. Specifically, "Some particles show evidence of being exposed to a conflagration such as spherical metals and silicates, and vesicular particles (round open porous structure having a Swiss cheese appearance as a result of boiling and evaporation)." Melting aluminosilicates requires about 1450 degrees C. Craig did not seem familiar with RJ Lee's ***ysis and replied along the lines that "9/11 websites" have made too much of the temperatures issue. He says he doesn't know about how such a phenomena could happen so he supports a new investigation into 9/11. At least Craig is the first explosives/special effects expert to speak about 9/11. We appreciate he interest and efforts regarding 9/11 research. However, since 2007 when he debated Richard Gage, he hasn't published any of his finding so that they may be scrutinized.

Types Of Ores Check us out at An ore is a type of rock that contains minerals with important elements including metals. The ores are extracted through mining; these are then refined to extract the valuable element(s). The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighted against the contained metal value of the rock to determine what ore can be profitably extracted and what ore is of too low a grade to be worth mining. Metal ores are generally oxides, sulfides, silicates, or "native" metals (such as native copper) that are not commonly concentrated in the Earth's crust or "noble" metals (not usually forming compounds) such as gold. The ores must be processed to extract the metals of interest from the waste rock and from the ore minerals. Ore bodies are formed by a variety of geological processes. The process of ore formation is called ore genesis. Important ore minerals •Acanthite: Ag2S for production of silver •Barite: BaSO4 •Bauxite Al2O3 for production of aluminium •Beryl: Be3Al2(SiO3)6 •Bornite: Cu5FeS4 •Cassiterite: SnO2 •Chalcocite: Cu2S for production of copper •Chalcopyrite: CuFeS2 •Chromite: (Fe, Mg)Cr2O4 for production of chromium •Cinnabar: HgS for production of mercury •Cobaltite: (Co, Fe)AsS •Columbite-Tantalite or Coltan: (Fe, Mn)(Nb, Ta)2O6 •Galena: PbS •Gold: Au, typically associated with quartz or as placer ...

A Tour Of Planet Kepler-10b [720p] Kepler-10b as a scorched world, orbiting at a distance that's more than 20 times closer to its star than Mercury is to our own Sun. The daytime temperature's expected to be more than 2500 degrees Fahrenheit, hotter than lava flows here on Earth. Intense radiation from the star has kept the planet from holding onto an atmosphere, but the animation shows flecks of silicates and iron that have boiled off a molten surface and are swept away by the stellar radiation, much like a comet's tail when its orbit brings it close to the Sun. Many years ago, before Kepler, our team built a robotic telescope at Lick Observatory to learn to do transit photometry. We called it the "Vulcan Telescope," named after the hypothetical planet that scientists in the 1800's thought might exist between the Sun and Mercury. A planet that might explain the small deviations in Mercury's orbit that were later explained with Einstein's theory of general relativity. Vulcan is the god of fire in Roman mythology, a name befitting of a world so close to the Sun. When I saw the artist's rendering of Kepler-10b for the first time, the thought that immediately came to my mind was that this is our planet Vulcan. We'd come full circle in our quest and we know that we've only begun to imagine the possibilities. credit: NASA / Kepler Mission / Dana Berry source: kepler.nasa.gov

Pedal-Powered (Vacuum) Zeolite Refrigerator The refrigerator works by creating a vacuum in a system of 2 chambers to drive a thermodynamic reaction (boiling of water) at room temperature. The lowering in vapor pressure of the water, drives the water to boil. In order to do this, the water must capture heat from a system (the inside of the refrigerator). The continued pedaling (which drives the vacuum pump down to 10^-2 atm) will ensure that the water freezes as it continues to boil. After only about 10 min of pedaling, the valve to the vacuum pump can be shut off, and the zeolite container line opened. Zeolite are common absorbers based on aluminum silicates and will swell up to 30% its mass with water. The zeolite then absorbs the vapor produced by the boiling of the water, and, in order for the liquid water to remain in equilibrium with the vapor phase, it must continue to boil (for up to a day). In general, one can achieve constant temperatures of 0-6 Celsius for 1 day with only 10min of pedaling. Now this is a real way to cool for cheap. Even ice cubes can be made, and one cool advantage of this system is that the hotter it is outside, the more cold you can generate!
Island Of Terror (1966) From Wikipedia, the free encyclopedia Island of Terror Directed by Terence Fisher Produced by Tom Blakely Written by Edward Mann Al Ramsen Starring Edward Judd Peter Cushing Carole Gray Eddie Byrne Music by Malcolm Lockyer Editing by Thelma Connell Distributed by Planet Film Distributors Universal Studios (US) Release date(s) 1966 Running time 89 min. Country UK Language English Island of Terror is a 1966 British horror film released by Planet Film Productions. The film was released in the US by Universal Studios on a double bill with The Projected Man (1967). The idea for the film came when Richard Gordon read the screenplay The Night the Silicates Came from Gerry Fernback. He partnered with Tom Blakey of Planet Films to produce this movie. It was shot in rural England using naturalistic colors. This film is one of the last significant examples of a common 1950s plot style in which a horrific threat introduced by a scientist is resolved by others using "responsible" scientific measures. On the remote Petrie's Island, farmer Ian Bellows goes missing and his wife contacts the local constabulary. Constable John Harris goes looking for him and finds him dead in a cave without a single bone in his body. Horrified, Harris swiftly fetches the town physician Dr. Reginald Landers, but Dr. Landers is unable to determine what happened to the dead man's skeleton. Landers journeys to the mainland to seek the help of a noted pathologist, Dr. Brian Stanley in London. Like Landers ...

Are Zeolite Crystals Grown in Space Viable for Nanotechnology? My avatar's name is Archivist Llewellyn and I am asking a question from Second Life. Carbon nanostructures can be grown in high yield inside the pores of Zeolite crystals, which are alumino-silicate semiconductors. My question is, does the quality of the crystals make a difference? If so, would crystals grown in space, shown to have higher quality, be a viable option?
