Nuclear magnetic resonance spectroscopy Updated 2025-07-16

Used to identify organic compounds.

Seems to be based on the effects that electrons around the nuclei (shielding electrons) have on the outcome of NMR.

So it is a bit unlike MRI where you are interested in the position of certain nuclei in space (of course, these being atoms, you can't see their positions in space).

What's Nuclear Magnetic Resonance by Bruker Corporation (2020)

Source. Good 3D animations showing the structure of the NMR machine. We understand that it is very bulky largely due to the cryogenic system. It then talks a bit about organic compound identification by talking about ethanol, i.e. this is NMR spectroscopy, but it is a bit too much to follow closely. Basically the electron configuration alters the nuclear response somehow, and allows identifying functional groups.

youtu.be/TQegSF4ZiIQ?t=465 usage of non-ionizing radiation (only radio frequencies) means that it is very safe to use. The only dangerous part is the magnetic field interacting with metallic objects.

Dr Mansfield's MRI MEDICAL MARVEL by BBC

. Source. Broadcast in 1978. Description:

Tomorrow's World gave audiences a true world first as Dr Peter Mansfield of the University of Nottingham demonstrated the first full body prototype device for Magnetic resonance imaging (MRI), allowing us to see inside the human body without the use of X-rays.

Featuring the yet-to-be 2003 Nobel Prize in Physiology and Medicine Dr. Mansfield.

Nuclear reactor Updated 2025-07-16

Some of the most notable ones:

1942: Chicago Pile-1: the first human-made nuclear chain reaction.
1943: X-10 Graphite Reactor: an intermediate step between the nuclear chain reaction prototype Chicago Pile-1 and the full blown mass production at Hanford site. Located in the Oak Ridge National Laboratory.
1944: B Reactor at the Hanford site produced the plutonium used for Trinity and Fat Man
