uranium 235
Usually referred to as just u235. It is an isotope of uranium that differs from the element's other common isotope, u238, by its ability to cause a rapidly expanding fission chain reaction. A uranium nucleus that absorbs a neutron splits into two lighter nuclei; this is called nuclear fission. It releases either two or three neutrons which continue the reaction. In nuclear reactors, the reaction is slowed down by the addition of control rods which are made of elements such as boron, cadmium, and hafnium which can absorb a large number of neutrons. In nuclear bombs, the reaction is uncontrolled and the large amount of energy released creates a nuclear explosion. One atom of U-235 generates 200 MeV = 3.2 × 10-11 J, i.e. 18 TJ/mol = 77 TJ/kg. Only around 0.72% of all natural uranium is uranium-235, the rest being mostly uranium-238. This concentration is insufficient for a self sustaining reaction; enrichment, which just means separating out the uranium-238, must take place to get a usable concentration of uranium-235. For an explosion, approximately 90% purity is required.

This looks like a weird design but it looks cool
This T shirt is the best piece of material to have ever graced this Earth. The fine quality fabrics and in depth definition, which is professionally implanted on the back of the shirt, which makes for some very interesting talking points. Thank you Pablo Parmesan.

Glad I had utmost FREEDOM OF SPEECH to express in articulate detail what evv it is the fk i was on a rant about that day. I haven't even received my shirt. I just a few moments ago placed the order. That is how pleased 😄 I am. Fk yeah fk yeah. Very empowering experience. My thoughts turned into type, that made some shi# happen. Having freedom of expression was most definitely...one fk ton of fun. A fk ton can be quantified as exuberance an joy beyond expectation. Fk yeah fk yeah. Awesome>>>
Proofread much? She might seem "quite"? Please fix the spelling to "quiet". Can't believe I was considering this purchase...
Damonism T-shirt :+) I found this by accident while surfing through your site. I love this shirt. I bought one and wear it when I feel frisky.
Another hit!
Great shirt, great service. A big thumbs up👍🏻
I always get so many compliments when I wear this (my favorite) shirt. I have been able to give out my phone number to lots of nice old men and my parents think it's great that I have so many nice mentors grooming me into a nice young boy who is willing to "follow the rules ".
Very comfortable and love the tyoeface
