Abstract: In one aspect, the disclosure relates to open cell hydrogel networks, methods of making the same and baits formed from the same, methods of loading the same with attractant molecules and compositions, and methods of catching fish and/or other aquatic organisms using the same. The open cell hydrogel networks disclosed herein can be configured to have different properties based on the specific polymers used for synthesis as well as any initiators, catalysts, and/or crosslinkers, thus allowing the fabrication of suitable baits for a variety of target species. In some aspects, the open cell hydrogel networks can be used as a filter or drug delivery device.

Abstract: Disclosed herein are systems and methods relating to in-situ servo-hydraulic biomanipulators. In-situ servo-hydraulic bio-manipulators as described herein have the advantages over existing systems and methods at least by having a lower cost, interchangeable and/or disposal displacement devices coupled to the extrusion head, and mounting of the displacement head along the optical axis of a microscope for enhanced visibility and well clearance.

Abstract: The present disclosure provides for compositions including at least one type of water-soluble polymer, methods of making the water-soluble polymer, structures having the water-soluble polymer disposed thereof, and methods of use thereof.

Abstract: A device comprises a surface that is a hydrogel having a targeted mesh size that permits a low-speed friction coefficient near or lower that that typically reported for cartilage of 0.01 to 0.02, a transition. The device can be a contact lens to sit on the cornea where, during a blink, eyelid slides past the eye surface at about 100 mm s?1. The hydrodynamic lubrication of the hydrogel of the device separates the contact lens surface from the surfaces of the tarsal conjunctiva and marginal conjunctiva of the eyelid. Other devices that can comprise the hydrogel of a targeted mesh size are those that can contact cartilage of articulating joints.

Abstract: A hydrogel fishing bait has a fish attractive scent infused into a water swollen hydrogel. The hydrogel can be a copolymer of at least one water miscible monomer and a cross-linking monomer. The hydrogel can be a terpolymer of hydroxyethyl methacrylate (HEMA), acrylamide, and a crosslinking monomer. The hydrogel terpolymer can be prepared in the shape of a fish or other fish attracting shape. The scent can be an amino acid, protein, fatty acid, sugar, or any combination thereof, and can be from a natural or artificial source. The hydrogel can be filled with a fiber, mesh, or matrix material. The hydrogel can be an interpenetrating polymer network. The hydrogel can be biodegradable. The hydrogel baits when fully hydrated on their surface do not stick to each other.

Abstract: Embodiments of the present disclosure include electrically conductive solid lubricant transfer films, methods of making the same, and the like.

Abstract: A method for in-situ solid lubrication of sliding electrical contacts includes the steps of providing a device having a movable electrically conductive first member and an electrically conductive second member, the first and second member being in electrical contact at a slideable electrical contact, and automatically applying an electrically conductive solid lubricant transfer film to the slideable electrical contact during operation of the device. The applying step can be a deposition of the electrically conductive solid lubricant transfer film on a surface of the first member, wherein the electrically conductive solid lubricant transfer film is carried by movement of the first member to the electrical contact.
