temperatures (about 700°C or 1300°F). The reactors also resist attack by hydrogen gases which can corrode many metals, especially at high temperature and pressure. The catalyst in commercial ammonia synthesis is usually an iron oxide mixed with a small amount of additional "promoter" material. When the process begins, the hydrogen gas converts the catalyst to pure iron. Gradually, as the iron c

1. Understanding of Kimchi
History
Given the facts that Koreans have been using vegetables and making salt from ancient times, and the era of making fermented foods, such as pickled fishes and soy pastes, we can assume that some kinds of Kimchi have been made since the period of the Three States. Kimchi, Korean traditional fermented food, is stemmed from natural environment, su
Introduction (What is plasma?)
1. Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artif
