Liquid Gallium droplets under high vacuum do not stick on the glass.
We have developed this method many years ago to show the beauty of high pure gallium which is normally very sticky and oxidizes in air.
Copper+ doped Phosphate glass shows strong luminescence under UV light.
Under reducing conditions Cu+ Ions can be kept in the glass. They show a strong pale yellow luminescence under 365nm UV light. The picture below shows the same beads under daylight. The slight green blue color comes from traces of Cu2+ Ions. #elementcollector #crystalgrowth #lanthanideresearchgroup #collectingelements #elementsamples #crystals #periodictable #periodensystem #selteneerden #elementdisplay #RAREEARTH #chemistry #inorganicchemistry #opticalglasses #Opticalglass #opticalglassart #opticalglassdome #opticalglassescoloring

So beutifull, like this 360° video
Our new Nickel acrylic cube containing 6 high pure & shiny nickel rods.
looks great 😀
A 25mm big Osmium metal cube with 350 grams!
350 grams of Osmium, insane 😀

I just finished the assembly of the Bluetooth LE adapter and the programming of the android app to control my Ricor K535 cryo pumps. I always needed a way to avoid cables and bulky control software. Just need my smartphone to control, switch and monitor the cryogenic pump.
The App currently consists of 3 screens: Connection, Control, Settings.
These Bluetooth adapters can be used with all RS232 / RS485 controlled devices. Just need to write an app. Next project is more complicated and needs a microcontroller as receiver: Control 2 solenoid vacuum valves and two vacuum gauges to automatically flush and fill noble gas tubes with the correct amount of gas and pressure just by pressing a button on my mobile phone😀

Rhenium doped phosphate glass!
For the first time and after many unsuccessful attempts I was able to incorporate a small amount of Rhenium (~ 0.6 - 1 mol%) into an aluminum barium phosphate glass without immediate reduction to black Re.
On the right you see the colorless and transparent glass with fully dissolved Re in the +7 state. On the left there is the same glass where Re formed nano clusters after slow cooling under slight reducing conditions.
The picture below shows the pale yellow luminescence of the colorless glass under 257nm UV irradiation.
Very impressive! Is Rhenium known for fluorescence in glassy materials?
