📖 Über Nitrogen

Makes up 78% of Earth's atmosphere and is essential to all life as a component of amino acids, proteins, and DNA. The nitrogen cycle moves nitrogen between the atmosphere, soil, and living organisms. The Haber-Bosch process for synthesizing ammonia from nitrogen and hydrogen is arguably the most important industrial process in history.

🔧 Verwendungen und Anwendungen

  • Fertilizer production (via ammonia synthesis)
  • Liquid nitrogen for cryogenics and food preservation
  • Inert atmosphere for electronics manufacturing
  • Explosives (TNT, nitroglycerin contain nitrogen)
  • Airbags in vehicles

💡 Wusstest du?

Fakt: The Haber-Bosch process for fixing atmospheric nitrogen into ammonia feeds roughly half the world's population. Without synthetic nitrogen fertilizers, Earth could support only about 4 billion people at current agricultural practices.
