  • Publication number: 20240097685
    Abstract: A buffer circuit includes a power control circuit, an inverting circuit, and a voltage adjustment circuit. The power control circuit is configured to provide voltages based on an input signal and a mode signal, and the inverting circuit is configured to receive and invert the voltages to generate an output signal. The voltage adjustment circuit is configured to adjust voltage levels based on the mode signal and the output signal.

  • Patent number: 10322400
    Abstract: Provided is an adsorbent for capturing carbon dioxide and a method for manufacturing same, and more particularly, to an adsorbent for capturing carbon dioxide, including a magnesium oxide/titanium dioxide composite having wide surface area, large pore volume and good CO2 adsorption performance, and a method for manufacturing same. According to the present invention, a novel MgO based composite metal oxide which may stably adsorb CO2 at a low temperature such as room temperature is provided. The adsorbent for capturing carbon dioxide, including a magnesium oxide/titanium dioxide composite has good thermal stability, and controls basic sites easily, and is used in various fields for capturing carbon dioxide. In addition, by controlling the molar ratio of the metal ions of the magnesium oxide/titanium dioxide composite and controlling morphology, an adsorbent for capturing carbon dioxide having large surface area and pore volume and strong basic sites may be provided.
