    摘要: A plurality of carbonation plots are positioned in communication with atmospheric carbon dioxide to facilitate sequestration thereof via ambient weathering. The carbonation plots include a composition rich in metal oxides, which are positioned within the environment, such as on non-arable land, and exposed to the environment to react with carbon dioxide in the air and form metal carbonates. After about one year of exposure, the composition is recollected and calcined to produce a carbon dioxide stream and replenish the metal oxides, which can be redistributed in the carbonation plots to sequester additional carbon dioxide. The systems and methods of the present disclosure enable capture and redistribution of carbon dioxide for industrial-scale uses for very abundant quarry minerals and enable large-scale low-cost carbon capture projects for municipalities or corporations. CO2 removal from air via these methods and systems have a similar or lower cost than CO2 removal using DAC with synthetic sorbents or solvents.

    摘要: The present subject matter relates to techniques for opening target tissue. The disclosed system can include a navigation guidance device configured to locate and/or monitor the target tissue, a single-element transducer for stimulating the target tissue with focused ultrasound (FUS), and a processor configured to determine a cavitation mode. The navigation guidance device can include a cavitation detector and an arm. The single-element transducer can be attached to the arm and be configured to induce the FUS with a predetermined parameter to open the target tissue.
