CdSe is a semiconductor, and reducing the CdSe nanoparticle size increases its band gap through a process called quantum confinement. For smaller particles, it requires a photon to have higher energy (i.e. smaller wavelength) to be absorbed.
Gold particles derive their color from the scattering mechanism mentioned in the parent comment.
For datasets that fit in memory, Pandas seems like the best bet. Good I/O functions (JSON, CSV), easy slicing (numpy array-like syntax), and some sql-like operations (groupby, join).
For large datasets, you'd need a proper db.
So is Dataset then useful for datasets that cannot fit in memory but aren't too large?
"The manufacturing process for most solar panels involves manufacturing a block of sapphire or other crystalline silicon and then slicing a .2mm-thick sheet off of it with a wafering saw."
Painful
Here's a small subset:
* Alveo Energy
* Amprius
* Blue River Technology
* C3Nano
* Momentum Machines
* QuantumScape
* Solum
Although if the OP's simple model had a category for startups simultaneously validating customer demand and driving technological advantages, most of these companies would be there.
But one killer feature Keynote lacks is slide inheritance. I love using build-outs and I wish I could edit a parent slide and have the changes propagate to its children. This feature would be much easier to build out with a JS presentation framework.
What also helped is a tip borrowed from Steve Yegge [1] to bind C-x C-m to M-x (also C-c C-m, in case you miss the x). This avoids my most common use of Meta, allowing me to use the more comfortable Control (bound to Caps Lock).

Intellectual Ventures also has an applied science laboratory that's even spun out a startup, Kymeta [1], in which Bill Gates invested.
Kymeta is a very cool company; they're developing revolutionary satellite transceivers using metamaterials [2].

I choose Mathematica over python for a lot of scientific/numerical computing due to how "lisp-y" Mathematica is.
I'll be keeping a keen eye on Julia as well!
Did you try anything creative with the fund terms or was it pretty standard VC fund structuring? I've heard that there's often LP pushback against changing standard terms, even if the changed terms might better align LP and VC incentives. I'm also curious if LPs view investment in a micro-fund the same as they would a larger, traditional VC fund.
