In 1824 Berzelius, generally credited with the discovery, prepared amorphous silicon by the same general method and purified the product by removing the fluosilicates by repeated washings. Deville in 1854 first prepared crystalline silicon, the second allotropic form of the element.

For reboilers, especially thermosyphon types, the devil is in the details. The information presented herein is intended for preliminary work. Final design is performed by experienced engineers using detailed design techniques. 

In conducting a dry run, pay particular attention to the question and answer session ask your colleagues to play devil s advocate and challenge your proposal. If you are preparing by yourself, review your proposal critically and try to anticipate the toughest possible questbns. 

As a final task in estimating resource requirements, ask the team to play devil s advocate. Given the range of experience the team represents, they should be able to poke holes in even the most precise, well-considered estimates. This will help you identify areas in which your numbers maybe soft and flag those in which you may have been overly ambitious in terms of time requirements. 

You can choose any of a number of methods for conducting these checks. One involves developing a systematic checklist or grid that displays the criteria themselves and checks each modification against them. In addition, as with previous exercises, it s often useful to call on your colleagues on the PSM team, or on other advisors, and ask them to play devil s advocate. It s often useful to combine methods such as these, because together they yield both a quantitative assessment ("Does this modification do what we said we wanted it to do ") and a more qualitative judgment ("Will this modification work in actual practice ").

An alloy of nickel was known in China over 2000 years ago, and Saxon miners were familiar with the reddish-coloured ore, NiAs, which superficially resembles CU2O. These miners attributed their inability to extract copper from this source to the work of the devil and named the ore Kupfemickel (Old Nick s copper). In 1751 A. F. Cronstedt isolated an impure metal from some Swedish ores and, identifying it with the metallic component of Kupfemickel, named the new metal nickel . In 1804 J. B. Richter produced a much purer sample and so was able to determine its physical properties more accurately.

Derived from the German word meaning devil s copper, nickel is found predominantly in two isotopic forms, Ni (68% natural abundance) and Ni (26%). Ni exists in four oxidation states, 0, I, II, III, and IV. Ni(II), which is the most common oxidation state, has an ionic radius of —65 pm in the four-coordinate state and —80 pm in the octahedral low-spin state. The Ni(II) aqua cation exhibits a pAa of 9.9. It forms tight complexes with histidine (log Af = 15.9) and, among the first-row transition metals, is second only to Cu(II) in its ability to complex with acidic amino acids (log K( = 6-7 (7). Although Ni(II) is most common, the paramagnetic Ni(I) and Ni(III) states are also attainable. Ni(I), a (P metal, can exist only in the S = state, whereas Ni(lll), a cT ion, can be either S = or S =. ...

C21-0090. The first commercially successful method for the production of aluminum metal was developed in 1854 by H. Deville. The process relied on earlier work by the Danish scientist H. Oersted, who discovered that aluminum chloride is produced when chlorine gas is passed over hot aluminum oxide. Deville found that aluminum chloride reacts with sodium metal to give aluminum metal. Write balanced equations for these two reactions.
