Made a pair of earrings for a friend.
The maple seeds were dried, coated with graphite lacquer and then electroplated with copper. After rinsing an electroless silver plating was applied. I soldered a small eyelet to the tops and attached the hooks.
They have been worn for a few weeks now and still look good as new!
It looks wrong but feels soo right...
Paramagnetic glass!
Gadolinium 3+ in a phosphate glass, just need to increase the concentration so it can carry it's own weight.
That's some very attractive glass!
The Gd3+ concentration is finally high enough for the whole bead to be lifted by the magnet!
This almost feels like magic. A ferromagnetic alloy made from to non-magnetic metals!
"Bismanol" is an alloy of Bismuth and Manganese, developed in the 1950s by the Naval Ordnance Lab (as hinted to by the -nol in the name).
To make it, I melted 32.9g of Bi and then added 7.0g of Mn to the melt. The mixture was heated to ~800°C and then poured into a mold.
The ratio or the quenching might not be optimal to reach maximum magnetism, but I am pretty pleased with the result.
@gigabecquerel@chaos.social and I took some pretty sweet pictures of sugar crystals with the SEM at @FabLabMuc@muenchen.social . We really need to motorize the rotary axis to get even better animations.
This is homemade erbium doped tellurite glass! It uses a process called upconversion to transform infrared light into visible light.
Still have to work on quenching and tempering, but I am very happy that the physics works!
A friend (sadly not on Mastodon) at the FabLab crafted this masterpiece with a photocopier and a smol blahaj.

Success!
Third time's a charm! The sodium chloride vaporized a bit much but did its job nonetheless. Next time I'll use borax and a lower temperature.
A nice ingot of Cu2MnAl formed in the crucible.
It has a golden tinge as is usual for aluminium bronzes.
And it its very magnetic! Video in the next post!

When @gigabecquerel@chaos.social took the images of the superconducting wire I snuck some of my samples into the SEM chamber.
This electrochemically grown copper on a wire I used to hold objects while plating them. Different current densities seem to result in different structures.
