  • AMMONIA MANUFACTURING APPARATUS AND AMMONIA MANUFACTURING METHOD
    Publication number: 20240092646
    Abstract: An ammonia manufacturing apparatus includes: an ammonia synthesis unit synthesizing ammonia under a chemical reaction using hydrogen and nitrogen as a raw material gas in a reactor; and a heat storage unit including a heating medium. The heat storage unit can supply heat from the heating medium to the ammonia synthesis unit when an amount of the raw material gas supplied to the ammonia synthesis unit increases.

  • THREE-DIMENSIONAL STRUCTURE OF PROSTAGLANDIN D SYNTHASE AND UTILIZATION THEREOF
    Publication number: 20090263784
    Abstract: A method of designing an anti-allergic agent, sleep controlling agent, anti-obesity agent and remedy for brain injury acting via the inhibition of biosynthesis of prostaglandin D2. Crystal of a complex of human origin hematopoietic prostaglandin D synthase, glutathione, and a substrate analog or an inhibitor, etc are prepared and the three-dimensional structural coordinate of each atom in the complex is determined by X-ray crystal analysis.
