Gas molecules can be stored at a higher density on the surfaces of MOFs than in conventional tanks
Three-dimensional metal-organic framework with pore sizes in the nanometer range
Greater porosity = greater surface area
Rapid Development

Chemical reaction between Ag and Cu
Cu(s) + 2Ag+(aq) → Cu2+(aq) + 2Ag(s)
Coiled Copper wire Greatest surface area

Purpose To determine the effect of microgravity on
the formation of Silver Crystals
Hypothesis We predict that the silver crystals will form
the same as they do an earth in an environment with microgravity because the reaction does not depend on gravity.
Neutral buoyancy of water is similar to microgravity

1) Prepare a 0.1 molar solution of Silver Nitrate
2) Pour the Silver Nitrate solution into the FME tube
3) Place clamp above the Sliver Nitrate solution on the tube
4) Place the 20cm long coiled copper wire above the clamp and seal the tube Silver
