I have a Master’s degree in Chemistry, and find all your videos to be tremendously pertinent and entertaining. I regularly learn new things from them.

Interesting timing on this video. I’ve literally been working for over a year on a project at work to replace our 10 year old Cf-252 neutron source that we use to calibrate neutron dosimeters. Cf-252 is now insanely expensive. 1500 microgram source is a cool $1.3 million
I've watched this like 20 times in the past 2 years. I love how fluent the knowledge is, and the further I go in science, the more I understand and see without thinking. This is amazing. And to be fair, the first year I was in lots of biology with some chemistry. Wasn't sure what i'd want to get into.
Im a grad student who currently works with Cf-249 among other rare isotopes like this. Very excited to see this video! If anyone has questions feel free to ask!
I work as a Carpenter in a lot of Cement plants. They have these restricted areas where the machine is housed so no one gets near it. So cool to understand how the analysis happens during the separation process.
As a biochemist, I have deep respect for that chromatography. It is next level. I thought separating materials differing by less than 1 kDa to be high resolution. This atomic weight separation puts that to shame! Not to mention the ion exchange chemistry involved.
These videos remind me how lucky I was to get the chance to do research at Lawrence Berkeley Labs as an undergrad; just the level of science and history oozing from the walls is crazy. No jokes, Fermi's old cyclotron is just laying outside in the center of a round about, and there are reserved parking spots for Nobel laureates in front of every other building. Hope I can visit Oak Ridge one day (and Nottingham too!!).
I’ve been a geophysicist for over 4 decades and relish these presentations. I feel like a sponge trying o to absorb all that I can…as I once did as a starry eyed 12 year old. The host captures the enthusiasm for science that is the fuel that powers curiosity.
It's always a treat to see a new video from this channel, and as an undergrad recently studying actinide complex chemistry the information on a californium metallocene was fascinating!
The way the ORNL scientist is describing the process sounds simple, but I can't even begin to fathom how it was developed. All I know is that lanthanides and actinides are something that none of the students in the chemistry fraternity I was a part of really ever discussed, it was predominantly organic chemistry because that was huge at the time. These heavy elements were like "yeah they're there, they play by different rules", and that was it.
I wonder how much Californium actually exists around the world at the moment... And also at the mention of Fermium a few times in the video, I hope at some point a visible amount of it can be created enough to be photographed before it decays.
@@mastershooter64 The known picture of einsteinium was 300 micrograms of einsteinium-253, which has a half life of only 20 days. 300 micrograms is about 0.0003 grams. So, I still have hope that we will possible be able to assemble at least 100-300 micrograms of fermium-257!
@@zygarde718 They also believe, with a high enough neutron flux (1000× greater than any created so far in any reactors), it may be possible to skip past the "fermium gap" they call it (along with another "gap" at around element 106), and create macroscopic amounts of even higher elements (maybe copernicium, nihonium, and flerovium, in the island of stability)! It is all theoretical, but it is a spark of hope.
I also wonder if someone could make some sort of timelapse that somehow shows elements decaying into other elements. Of course, the elements would have to be distinguishable from each other, so probably a noble gas decaying into an alkali metal or halogen (fluorine and chlorine would be hard to see). The isotope may have to have a long half life in order to have an amount of it to be timelapsed, so it may take a long time (maybe years).
Los Alamos National Laboratory is located in my birthplace/hometown. I was never sure what was going on at the sister lab in Oak Ridge. This video helped fill in the gaps.
How do they change the lightbulbs in the cubicles? What sort of hazmat gear is required to do that? Is it the janitor’s job or does it require a PhD? Fascinating lab and chemistry, brilliant staff, amazing content as usual. Thanks for the insight into a local facility!
It would be interesting to get a color correction card into one of those shielded workrooms, then use software to color adjust for that greenish glass so you could see what it looks like if you were in there.

The Oak Ridge visit was one of my favourite videos, I really loved how detailed the description of the reactor was, and ofcurse seeing the huge blue cherenkov radiation was the best
I believe that tiny amounts of californium is used in certain designs of home fire alarms. I'm not sure exactly how it functions but I believe it is to do with how it detects the smoke.

Cf is used to investigatie explosives f.e. whether a grenade is filled with a conventional explosive charge or with a chemical or biological charge. The inspection effectiveness of ²⁵²Cf is useful with a thermal flux greater than or equal to 10⁷ n/cm² s. This means that there will then be about 22 micrograms of ²⁵²CF in the detector, corresponding to an activity of 436 MBq. Furthermore ²⁵²CF is used in clinical neutron therapy for cancer treatment (i.e. brachytherapy).
This seems like a pretty fulfilling field to work in. Not many people get to say that they make totally manmade radioactive elements in their lifetime. Might as well be a spacecraft engineer.
Questions about the container: if I understand correctly the polymer stops the thermal neutrons and the tungsten is to shield gamma. I noticed this independently when running thoriated tungsten rods under a spectrometer it was able to almost entirely shield my 1uCi cs-137 sample from detection. Ironically 2.5 mm of W seems equivalent to 12mm of Pb.
