  • Patent number: 10843172
    Abstract: ABSTRACT OF THE DISCLOSURE A catalyst for electrochemical ammonia synthesis incudes a carbon carrier composed of carbon; and 20-65 wt% of iron, copper and sulfur, based on weight of the carbon, supported in the carbon carrier. The catalyst may be coated on an electrode selected from the group consisting of carbon paper, carbon cloth, carbon felt, fluorine- doped tin oxide (FTO) conducting glass, and combinations thereof by spray coating, screen printing or ink jet printing. The catalyst has an ammonia synthesis activity up to several times to several tens of times of the activity of the existing single metal or metal oxide catalysts. Thus, when using the catalyst, it is possible to provide a method for electrochemical ammonia synthesis having an improved ammonia production yield and rate.

  • Patent number: 10832966
    Abstract: Structures and fabrication methods for a field-effect transistor. First and second spacers are formed adjacent to opposite sidewalls of a gate structure. A section of the gate structure is partially removed with a first etching process to form a cut that extends partially through the gate structure. After partially removing the section of the gate structure with the first etching process, upper sections of the first and second sidewall spacers arranged above the gate structure inside the cut are at least partially removed. After at least partially removing the upper sections of the first and second sidewall spacers, the section of the gate structure is completely removed from the cut with a second etching process. A dielectric material is deposited inside the cut to form a dielectric pillar.

  • Publication number: 20200335800
    Abstract: The present disclosure relates to a fluorine-doped tin oxide support, a platinum catalyst for a fuel cell comprising the same, and a method for producing the same. The present disclosure has a high electrical conductivity and electrochemical durability by doping fluorine to the tin oxide-based support through an electrospinning process. Thus, while resolving a degradation issue of the carbon support in the conventional commercially available platinum/carbon (Pt/C) catalyst, the present disclosure is designed to minimize an electrochemical elution of dopant or tin, which is a limitation of the tin oxide support itself and has excellent performance as a catalyst for a fuel cell.

  • Publication number: 20200191423
    Abstract: The disclosure an air conditioning system and a method of controlling the same. During the heating operation of the A2W indoor unit, the A2A valve that connects the outdoor unit to the A2A indoor unit is closed to prevent the inflow of the refrigerant into the A2A indoor unit, so it is possible to prevent performance degradation by improving performance loss due to refrigerant bypass to a stationary A2A indoor unit. In addition, in order to improve the performance due to deterioration of heating performance, the system itself can cope with a control algorithm without any additional hardware configuration, thereby minimizing the installation cost.
