Many thanks to all of you for being such a supportive audience.
I am glad that people were able to get the big concepts and ideas (which is what I was going for, after all). I actually had not noticed a fast pace while I was presenting, but I never do, so I think I need to make a serious effort to slow myself down while I speak. It definitely can be done. Thank you for that important tip, Veronica!
No, it's not when you're super (super-) late (-latt) and thus on ice (-ice).
Superlattices are mentioned very frequently in the literature, and they are often used in the context of quantum dots, so I thought it would be a good idea to write about what they actually are. They are basically a description of how materials are organized three-dimensionally.
A soft agar assay, or otherwise known as a colony formation assay, is a super fun (and slightly stressful) way of determining whether or not a mutation is transforming or not.
For this assay, 3T3 cell lines are used. Note: they are normally adherent to the bottom of a dish (in this case, wells in a 6-well plate). The soft agar method suspends a single cell in agar so that the cell becomes independent of any surface adherence. If the cell is transforming (with the mutation as the driver of the transformation), a small colony will form.

This is a preliminary analysis of the paper I will present to the class. I have attached the PDF. (Thank you Veronica!)
Vocabulary: (I defined terms like recombination and loading in prior posts, but I will include those terms when I present to class)
Quantitatively investigates optical properties of colloidal lead sulfide (PbS) quantum dots. Utilizes absorbance equations (Beer's Law, aka Beer-Lambert) and mentions helpful formulas for my own work (how bandgap theoretically relates to quantum dot size).
