Basics of X-Ray Powder Diffraction
long-range order, producing constructive interference at specific angles. • The electrons in an atom coherently scatter light. – We can regard each atom as a coherent point scatterer – The strength with which an atom scatters light is proportional to the number of electrons around the atom. • The atoms in a crystal are arranged in a periodic array and thus can diffract light. • The ...

How a Metal Detector Works - An overview and …
A long time constant (in the range of seconds) has the advantage of reducing noise and making the metal detector easier to tune. Long time constants require a very slow sweep of the coil because a target might be missed if it passes quickly by the search coil. Short time constants (in the range of tenths of a second) respond more quickly to targets. This allows a quicker sweep of the loop ...

The metal higher in the galvanic series of metals, the anode, provides protection for the metal lower in the series, the cathode.. As can be seen from the galvanic series, zinc protects the lower-order steel. With respect to contacting surface areas of the two metals, although the corrosion current that flows between the cathode and anode is independent of area, the rate of penetration at the ...

Chemical and Physical Properties of Gold - …
Gold is one of the few elements that can be found in its native state. Gold is the most malleable and ductile metal. One ounce of gold can be beaten out to 300 ft 2 or stretched into a wire 2000 kilometers long (1 μm thick).; The melting point of gold is an assigned value, which serves as a calibration point for the International Temperature Scale and International Practical Temperature Scale.

: Garrett Ace 400 Metal Detector …
This is my first decent metal detector since I sold the Ace 250 a few years back. I decided to give the hobby another try when we recently bought 26 acres of partially wooded land. Before the 400, I bought a cheap Chinese detector and quickly found that you get what you pay for. After lots of research and having a limited budget, I went with the Garrett Ace 400.
