    Abstract: A nanoclay based solid sorbent is provided having a nanoclay with at least one surface, and at least one amine containing compound wherein the amine containing compound is attached to the surface, as well as a method of making it. A method of capturing carbon dioxide gas is disclosed includes passing a gas from an effluent process stream containing carbon dioxide through the nanoclay based solid sorbent and capturing the carbon dioxide gas on the surface and within the nanoclay based solid sorbent. The nanoclay based solid sorbent having the captured carbon dioxide gas is regenerated by undergoing one or more cycles of desorption of the captured carbon dioxide gas from the nanoclay. The regenerated nanoclay based solid sorbent may then be reused.

    Abstract: A bandgap voltage reference and voltage regulator system includes a bandgap voltage reference circuit and a voltage regulator circuit that share a single, common amplifier. The amplifier acts as a gain stage for the reference circuit and as an error amplifier for a driver stage of the regulator circuit. The regulator circuit has an input reference generated by the reference circuit, and the reference circuit acts as a load to the driver stage, obviating the need for a bias resistance network. By sharing the amplifier and obviating the need for a resistance network, the area and overall quiescent current of the system are reduced. The system can be implemented in CMOS/BiCMOS technology and is suited for low power applications.
