Abstract: A gas separation unit for the separation of carbon dioxide from air is proposed for use in a cyclic adsorption/desorption process and using a loose particulate sorbent material. The loose particulate sorbent material is disposed within an internal volume of an external support structure and supported by the external support structure, the external support structure comprising a plurality of base portions, deflected portions, and openings. The sheets are arranged parallel defining an inlet face and an outlet face, are arranged with a distance in the range of 0.1-2.5 cm (preferably 0.1-0.5 cm), and the inflow passes through the inlet face, subsequently through the particular sorbent material located in the cavity of the respective layer, subsequently to exit the layer through the outlet face to form the gas outflow. Directionality of the inflow and the outflow through the external support structure is controlled by the deflected portions of the external support structure.

Abstract: A direct air capture (DAC) device and methods of controlling the same are disclosed herein. The DAC device includes a plurality of contactor elements that are aligned with respect to each other to facilitate homogenous drying and have a plurality of spacings located therebetween such that each of the contactor elements defines a contactor volume and each of the spacings defines a spacing volume. The DAC device has a total volume defined by the contactor volumes and the spacing volumes such that the DAC device is modifiable to (a) reduce the total volume for the contactor elements to facilitate desorption of one or more components of a feed stream and (b) increase the total volume for the contactor elements to facilitate adsorption of the one or more components of the feed stream.

Abstract: A sorbent article is described including a plurality of sorbent elements structured to adsorb and desorb CO2 and a plurality of hydrophobic elements mixed with the plurality of sorbent elements and structured to exert hydrophobic force to expel liquid water from the sorbent article. Also described herein are methods of forming such sorbent articles for the purpose of swing adsorption, including for direct air capture (DAC) of carbon dioxide.

Abstract: A dental floss cartridge is disclosed. The cartridge includes a housing, a roll of dental floss comprising a polymer such that the dental floss has a first surface and a second surface, a floss exit opening in the housing through which the floss is configured to exit, a texture-inducing structure arranged within the housing and configured to impart texture onto at least one of the first and second surfaces of the dental floss prior to or during the dental floss passing through the floss exit opening, and a cutting device on an exterior of the housing configured to cut the dental floss into a desired length.

Abstract: Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a medical device including a remotely actuated cross-sectional adjustment mechanism. The medical device may include a cross-sectional adjustment mechanism configured to actuate an implantable medical device between a first dimension and a second dimension that is larger than a first dimension to adjust an amount of fluid flow through the implantable medical device.

Abstract: The present disclosure relates to medical devices such as syringes, auto-injectors, and pens that inhibit oxygen permeation into the fluid chamber. The medical device includes a lubricant-free (e.g., silicone) or a siliconized barrel having an interior surface defining a fluid chamber, an elastomeric stopper, and a plunger rod. In one embodiment, at least a portion of the interior surface of the barrel is reduced to increase the interference fit between the stopper and the barrel. In another embodiment, the stopper may include a plurality of ribs and a valley between each pair of ribs may include a ring member provided in each of the valleys. The ring member includes an oxygen-absorbing, an oxygen-adsorbing material, or both, to bind any oxygen that permeates into the syringe, auto-injector, or pen.
