Absolutely stunning plutonium (III) crystals this morning! #plutonium #fblockrocks

@duolingo why is there no option for me to turn off the word bank?

@Bai_bai_123 doing a plutonium-242 purification column. More examples of the #colorfulchemistry of #plutonium!

@And1129 @Jsperling91 @TEAS_Actinides Holmium is one of the more stark contrasts in color. Intense pink in fluorescent light and yellow in natural light

@RotermundBrian @Jsperling91 @TEAS_Actinides Yeah, I've seen Alexandrites do that, but never a liquid solution. I might have to try it with those other metals! 🤔👨‍🔬

The alexandrite effects of plutonium! In select elements, by changing the light emitting conditions, different colors are observed from the sample despite no chemical changes occurring! @Jsperling91 @TEAS_Actinides #Plutonium #colorfulchemistry #actinides

@And1129 @Jsperling91 @TEAS_Actinides If you have enough concentration to see color then you should be able to observe the effect. Other elements that have the alexandrite effect are U(III)/(IV), Nd, and Ho. TM have the effect too. The namesake of the effect from the mineral alexandrite I believe is due to chromium.

@RotermundBrian @Jsperling91 @TEAS_Actinides If I could ask... what is the concentration of Pu in those solutions needed to observe that effect?? 🤔 Do other metals show similar behavior? Very cool!

@acid_angelic Absolutely. High radiation fields can degrade sensitive ligands before they even have time to crystallize. This is especially the case with our more radioactive isotopes like Cf-249 and Bk-249

@RotermundBrian I see. I guess purity in radioisotope is a whole different ball game. Does radioactivity impact on crystal growth?

Turn your brightness up! The static you see here is from gamma radiation from Am-243 hitting the camera sensor! #radiation #radioactivity #americium

@acid_angelic We are currently purifying our stock of Am-243 but in our group we make coordination compounds with actinides such as americium. We can get some beautiful crystals and a lot of valuable information from the compounds we create.

@RotermundBrian What are you planning on doing with the Am243?

Some fantastic looking clean neptunium (IV) at decreasing concentrations! @TEAS_Actinides @Jsperling91 #colorfulchemsitry #actinides #neptunium

Mines researchers isolate first molecule of californium 2+ minesnewsroom.com/news/mines-res…

A time lapse by @RotermundBrian from team @TEAS_Actinides showing neptunium elute from an ion exchange column. #fblockrocks #RealTimeChem

Neptunium Funtime with the @TEAS_Actinides group. This is how much Np precipitated after about 5 minutes. Excited to see what Monday brings. Photo cred: @RotermundBrian #fblockrocks

With larger, purer batches, @ORNL is moving closer to #routine #production of #promethium-147. Researchers rescue the #isotope, used for #nuclear #batteries and thin film #measurement, from byproducts of #Pu-238 ORNL produces for #space travel. ornl.gov/news/changing-…

After struggling with this americium reaction for 2 weeks, I've finally got the very exciting results I was after! #fblockrocks #americium @TEAS_Actinides
