[생명공학개론] Hydrogen Production-Manipulation of Enzyme Hydrogenase(영문)
Hydrogen Production:Manipulation of Enzyme HydrogenaseOur Planet is going through serious green house effect and therefore global warming. By continuing to use fossil fuels and other limited resources, we are constantly destroying our own atmosphere. An alternative solution to these fuels can be ‘biofuels’. Biofuels are wide range of fuels that are in some way derived from biomasses. There

are very high but they are limited. To supplement this flaw new energies are being developed. They are just solar energy and hydrogen energy. First, solar energy is that using the heat from the sun to earth. It isnt limited to use and does not cause bad effects on the environment. If we can use this energy generally there will be a lot of advantage. Recently new material was made to use solar e

are always unstable and that causes the global problem. The finitude of original resources and threat to the environment also motivate the development of new energy. In this stream, the energy of nuclear fission and nuclear fusion, solar energy, subterranean heat energy, hydrogen energy, tidal energy and so on are researched with activity by scientists. Among them, hydrogen energy system supremel

are designed to withstand very high pressures (up to one thousand atmospheres) and high 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 proce

are supplied. Fuel cell construction generally consists of a fuel electrode (anode) and an oxidant electrode (cathode), and they are separated by an ion-conducting membrane. Oxygen passes over one electrode, and hydrogen over the other, and it generates electricity, water and heat. Fuel cells chemically combine the molecules of a fuel and oxidizer without pollution of traditional combustion. In

Thehydrogen peroxide and the luminol are actually the principal players in the chemical reaction,but in order to produce a strong glow, they need a catalyst to accelerate the process. The mixtureis actually detecting the presence of such a catalyst, in this case the iron in hemoglobin. If
