Difference between Fission and Fusion?

Physics
[caption id="attachment_13674" align="alignright" width="440"] Deuterium-Tritium Fusion[/caption] In the 1900s, seeming peace was rudely interrupted by two developments in nuclear science. The first was fission. The second was fusion. Both can be used in positive ways. But rarely does mankind focus on good. What’s the difference between fission and fusion? Fission Fission is the dividing or splitting of something. This word well applies to the splitting of the atom. More often than not, that atom is the uranium atom. In particular, it is 235U. The 235 stands for isotope atomic weight. There are other isotopes of uranium, most notably 238U. Atoms are fissionable with a net release of energy if they have an atomic weight higher than approximately that of iron. Fusion Fusion behaves in the opposite manner. Fusion is defined…

Organic Chemistry: What is a Lactam?

Chemistry
Most have never heard of a lactam. What is it? How can it be produced? Compounds are chemicals formed by combining two or more different atoms, the basic building blocks of matter. Organic compounds contain carbon, frequently bonded to itself, whether in chains, rings, or some other geometric structure. There are so many organic compounds, they must be categorized according to "functional groups." Functional groups are specialized structures within a compound that may contain a special atom, such as nitrogen, sulfur, phosphorous, etc. One kind of compound categorized by functional group is an amide. An amide results when an organic acid group reacts with a nitrogen-containing amine group and loses water. A lactam is a special kind of amide. It may serve as an intermediate in forming heterocyclic rings. Inorganic…
