Abstract: The present disclosure generally relates in certain embodiments to a combined cycle power plant system comprising an electrochemical compressor. For instance, in one set of embodiments, the electrochemical compressor is may separate oxygen from a flow of air from an air source to provide a pressurized flow of oxygen to a combustor. In some embodiments, the resulting combustion products may only include oxygen and water without any substantial fraction of other combustion products or contaminants which may facilitate the separation of carbon dioxide (CO2) for subsequent processes including compression and/or storage.

Abstract: An auxiliary label device for attaching to an object, such as a container having a side wall, includes a label enclosure that includes a longitudinal slot therethrough, a bottom side, and a top side. A rotatable spool fixed within the label enclosure is fixed with a first end of a label that traverses the slot of the label enclosure. A spring connected between the label enclosure and the spool urges the spool to wind the label around the spool in a coiled configuration. A second opposing end of the label is attached to the container, and with the spool and label under tension of the spring to urge the label around the spool, the label enclosure is urged to contact the container. The label thereafter is unwound from the spool in an extended configuration for viewing when the label enclosure is manually grasped and pulled away from the container.

Abstract: Barocaloric heat transfer systems and related methods are generally described. In some embodiments, a heat transfer system may include a barocaloric material which may generate heat upon compression and may cool down upon decompression. The barocaloric material may be pressurized using high pressure and low pressure fluids, which may, in some embodiments, also transfer heat to/from the barocaloric material. The heat transfer system may also include a hot heat exchanger to dissipate heat from the heat transfer system to a first environment and a cold heat exchanger to absorb heat from a second environment, effectively cooling the second environment. In some embodiments, the barocaloric material may be in particulate form.
