MY2100 – Ch 2, Slide 3 Basic Length Scales of Structures We will talk about structures in MY2100 in the order of increasing length scales: Atomic Structure: Nanometer (10 -9 meter) scale What elements are present? What type of chemical bonding exists between atoms? Crystal/molecular: Slightly larger but still on the Nanometer scale What is the basic building block of solids? Microstructure: Micron (10 -6 meter) scale How large are individual phases? What shape do individual phases exhibit? How are phases configured spatially with respect to each other?

MY2100 – Ch 2, Slide 4 Influence of structure Atomic structure strongly affects: Physical properties (electrical conductivity, specific heat, optical properties, semiconducting properties, chemical reactivity, etc.) We will briefly review only those aspects of atomic structure that are related to bonding. Crystal and microstructure strongly affect: Mechanical properties (strength, toughness, etc) However, each level of structure can have smaller effects on all properties of importance.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
