Abstract: Embodiments disclosed herein are directed to a cathlock system integrally formed with a port or similar access device. The cathlock mechanism can include a shroud defining a recess, a stem disposed therein, and a collet lock transitionable between an unlocked and a locked configuration. The system can further include a tool configured to engage an outer surface of the cathlock and plastically deform the collet lock into the recess to the locked configuration. The collet lock can compress the catheter onto the stem to form a fluid-tight seal therebetween. The collet lock can be configured to engage the cathlock mechanism in the open configuration to facilitate coupling the catheter with the cathlock within the confined environment of a subcutaneous placement. Embodiments can include an extension leg disposed between the port and the cathlock mechanism.

Abstract: A system, composition, method and kit for removing a detergent, such as an anionic detergent, from an aqueous solution, comprising a salt, a water immiscible alcohol of Formula I: R1—OH??(Formula I) where R1 is an optionally substituted, linear, branched or cyclic C4-C12 alkyl; and a water immiscible halocarbon, wherein said halocarbon is miscible with said alcohol of Formula I. The system can be used on aqueous solutions that contain detergents (such as Sodium Dodecyl Sulphate (SDS), for example), and any detergent-associated or detergent-bound molecules that may be present in the aqueous solution, to form an aqueous phase and a non-aqueous phase, for effectively removing the detergent and any detergent-associated or detergent-bound molecules, and sequestering them into the non-aqueous phase.

Abstract: Methods of functionalizing activated carbon for selective adsorption of a per- or polyfluoroalkyl substance (PFAS), methods of removing PFAS, and compositions comprising activated carbon; and a molecularly imprinted polymer (MIP) coupled to the activated carbon are described. In the embodiment, the method of functionalizing activated carbon for selective adsorption of a PFAS comprises coordinating a PFAS template with a plurality of functional monomers; polymerizing the plurality of functional monomers coordinated with the PFAS template in the presence of an activated carbon substrate to provide a molecularly imprinted polymer (MIP) coupled to the activated carbon; and extracting the PFAS template from the MIP.

Abstract: A cooler with a dry interior chamber that effectively keeps beverages cold without subjecting them to moisture. By combining a highly insulated outer container with an inner container designed for efficient cooling, this invention prevents labels from peeling off and enhances the overall beverage experience. Additionally, the depth of the ice chamber is adjustable, offering versatility to suit varying needs while reducing the required amount of ice.

Abstract: A method of producing biochar from spent coffee grounds, biochar, such as biochar produced according to the methods of the present disclosure, an environmental remediation system including biochar according to embodiments of the present disclosure, and methods of removing contaminants from an aqueous solution using biochar according to embodiments of the present disclosure are described. In an embodiment, the method of producing biochar from spent coffee grounds comprises heating dried spent coffee grounds in an oven in a first pyrolysis temperature range to provide an intermediate biochar; and heating the intermediate biochar and a caustic in the oven in a second pyrolysis temperature range to provide the biochar.
