Another great video from NurdRage. One of the most detailed and methodical YouTube chemists.

New NurdRage video!

Nice to see another amateur-accessible source of thorium, since incandescent gas mantles have mostly switched to yttrium.

I wonder what the easiest way would be to reduce the thorium dioxide to thorium metal?

Making liquid nitrogen is quite an achievement, especially using salvaged air conditioner and refrigerator parts. A nice application of the Joule-Thomson effect and countercurrent exchange too.

Another useful example of producing a strong acid from a weak acid by using precipitation as the driving force.

Cody plays with thermite... again.

One of the OG YouTube chemists dabbles in some radiochemistry and spectroscopy.

Not very practical, but the chemistry is interesting. Producing a strong acid from a weak acid by using precipitation as the driving force is something I don't see very often.

A bit of analytical chemistry for a change. I had never heard of a pycnometer!

Very useful video. Nitrate salts are a foundational feedstock in amateur (and professional) chemistry.

Edit: NurdRage reuploaded a slightly censored version: https://www.youtube.com/watch?v=RlonW4iJYrw

NurdRage has published a couple videos on oleum synthesis:

• Lab Notes - Making Oleum - Successful - (April 21-2024)
• Lab notes - Making Oleum - 20% yield improvement - (May 4th - 2024)

Still optimizations to be done, but cool work so far. I love that one of the OG chemistry YouTubers is still doing interesting work.

A long-time viewer of Periodic Videos grew up to study chemistry, and invented a new synthetic route for thalidomide.

Also, TIL that thalidomide still has several medical uses, as long as the recipients are not pregnant.
