Sounds like your education system is much better over in the UK than here in the USA at least pertaining to these subjects. I didn't learn about materials science to this level until I started pursuing my engineering degree at university. It's a damn shame, so much time in American grade school is wasted on busy work or useless subjects no one cares about, and they wonder why students don't stay engaged and end up losing interest. Hell I hated school myself until I went to university, it was a frickin joke. The grade schools I went to were even considered better-than-average! But when the average is almost 30th in the world... oof I'm not looking forward to figuring out what I'm going to do for education when I have children.
The articles linked in here also give excellent explanations of how and why the cryo process works. The NitroFreeze one is perfect.
