That's just me. YMMV
@masterswimmer. Gold should feel like gold. If this should somehow become a coin/bullion application I would be very disappointed.
That's interesting, because I've been looking for "a metal so lightweight it could float on cappuccino froth."
or maybe woven into hoarders "gold underwear" . Imagine showing up at the next CT convention with that. Jim
Darn it. I didn't know I missed the last one!
Maybe starting some local chapters, I would put Coin talk on my name tag!
or make some buttons like the East Coasters.
So you can eat the stuff with less indigestion?
And heavens. This stuff will never replace a good whiskey or bourbon....
I didn't know we had one!
Never could get a taste for legalized moonshine, or even the homemade brews,
I prefer beer.
From the paper:
>A new 18 karat light gold, composed of gold single crystals, amyloids, and a polymer latex matrix is developed. It is similar to a glassy plastic, yet lighter than aluminum and of use in watches, jewelry, radiation shielding, catalysis, and electronics. The material is prepared via a hydrogel precursor dried into an aerogel. Annealing of the polystyrene matrix under vacuum gives rise to a homogeneous template. The final apparent density and porosity of the material depend directly on the volumetric concentration of the starting solution used for hydrogel formation. After annealing, a homogeneous microstructure is obtained in which the shining gold single crystal platelets are evenly embedded in a polystyrene matrix. The material has a glass transition temperature of ≈105 °C which allows for annealing and molding above this temperature. A general scaling behavior is found for the Young's modulus of the material with the density. The Young's modulus of the material with a density of 1.7 g cm−3 is ≈50 MPa. The density and stiffness, as well as the color, of the material can be tuned depending on the final application.
If it's polystyrene, then it dissolves in Acetone, Xylene, Benzene, and Toluene...
