I read the article from above and learned these four things:
1- Atomic bonds dictate characteristics of an element or compound, such as melting point, hardness, or transparency.
2- It is possible to influence the assembly process of silicon crystals by applying strain as the bonds are forming.
3- Straining these bonds can affect an element or compound's chemical reactivity greatly, and that in turn will also cause the structure of the element/compound to change.
4- Using this method of straining the crystals in one way or another can prove to make silicon and silicon products much more efficient in the future, when more extensive research will be done.

Alloys
What is an Alloy?
An alloy is a metallic solution, composed of two or more metallic elements. It can be a homogeneous solution, which would be a solution that is uniform, or it can be a heterogeneous solution, which would be a solution that is unevenly distributed throughout.
Examples and Uses
1. Bronze is a mixture typically consisting of copper and tin. In some cases, zinc is substituted for tin. This solution used to be required to make tools, but now is generally used for door knobs, handles, and other small parts. It is also used in sculptures, and some countries used bronze for their pennies (such as England).
2. Aluminum alloy, also known as magnalium, is a mixture made up of aluminum and magnesium. There are varying forms of this alloy, ranging from containing 5% magnesium and 95% aluminum, to a 50/50 differential. The more magnesium in the solution, the more brittle and more susceptible to corrosion it is. It is often used in aircraft and auto parts, such as the chassis (frame of the car), or the wheel hubs.
