[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

[설계] 수소저장 능력이 우수한 마그네슘 복합재료의 개발
Hydrogen diffusion and effect of grain size on hydrogenation kinetics in magnesium hydrides”를 살펴보면 실험을 통해 100~300°C에서 Mg중의 수소 확산의 활성화 에너지 Ea = 24.07±0.48kJ/mol을 측정하였다.결국, Mg2NiH4중의 수소 확산의 활성화 에너지가 Mg중의 수소 확산의 활성화 에너지가보다 더 작으므로 Mg에 Ni를 첨가하면, Mg2Ni

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 supremely comes into the spotlight. Hydrogen energy system bases an ideal principle which hydrogen is produced from water and returns to the original substance; water after b

[반응공학] 암모니아 합성(Ammonia synthesis)영문
in 1901. During World War I, synthetic ammonia was used to manufacture ammunition after Germanys nitrate supplies had been cut off. Commercial ammonia synthesis takes place in large steel reactors that 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

The source of Energy A summary of the physical and chemical nature of life must begin, not on the Earth, but in the Sun; in fact, at the Sun’s very center. It is here that is to be found the source of the energy that the Sun constantly pours out into space as light and heat. This energy is librated at the center of the Sun as billions upon billions of nuclei of hydrogen atoms collide with each
