[pic] Intro Turn a calculator into a metal detector I recently discovered a really cool method in using a few household items to make a HomeMade Metal Detector! Heres how to make your own! Heres a link to the video : http://www.youtube.com/watch?v=_G5HzeIl9cY [pic] Step 1 What you need. All you need for this project is‚ an: AM Radio ‚ some tape ‚ and a small calculator.

determine challenging structures. Widely used by both specialists and non-specialists‚ XAS is a mature technology that is also enabling the advancement of new areas of science. Examples • identification of therapeutic target sites‚ such as the metal-binding sites that may be responsible for some of the pathological effects of Alzheimer’s disease • elucidation of the chemistry associated with enzyme catalysis‚ particularly in relation to the influence of redox or charge state on the electronic

some percentage of their electronic waste to China or poor countries in Africa‚ where the waste is “recycled‚” or destroyed and stripped of its valuable metals. Though this seems like a good thing on the surface‚ because components are being repurposed‚ unregulated recycling centers burn or dissolve the plastic components to release the precious metals: a process that releases environmental contaminants into the air‚ land‚ and water that would otherwise remain trapped and inert in landfills (Robinson

A clothing iron‚ also called a flatiron or simply an iron‚ is a small appliance: a handheld piece of equipment with a flat‚ roughly triangular surface that‚ when heated‚ is used to press clothes to remove creases. It is named for the metal of which the device is commonly made‚ and the use of it is generally called ironing. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are

1.Compare and contrast the crystal structures and crystal chemistry of quartz α-FePO4 and β-FePO4 FePO4 is an extremely distinct quartz as its cation is a transition metal. It is often looked in depth at temperatures ranging from 294K to 1073K. When it is at a relatively low temperature‚ we see the quartz at α-FePO4. It takes on a tetrahedral shape. At higher temperatures‚ the α-FePO4 will transition to β-FePO4 and takes on an octahedral shape. Very importantly‚ the temperature at which this transition

Extrusion is the process by which a block/billet of metal is reduced in cross section by forcing it to flow through a die orifice under high pressure. • In general‚ extrusion is used to produce cylindrical bars or hollow tubes or for the starting stock for drawn rod‚ cold extrusion or forged products. • Most metals are hot extruded due to large amount of forces required in extrusion. Complex shape can be extruded from the more readily extrudable metals such as aluminium. * The products obtained are also
