Abstract: Enhanced cleaning of a fouled membrane is achieved via controlled deformation in a method wherein a feed composition, comprising a solvent and dissolved components, flows into a retentate side of a membrane module. The solvent passes through the membrane from the retentate side to a permeate or draw side of the membrane module while retaining the dissolved components on the membrane. As a foulant accumulates on either side of the membrane, a driving force is generated across the membrane, wherein the membrane responds cyclically by deforming back and forth toward the permeate or draw side and toward the retentate side. The foulant is dislodged from the membrane via mechanical fatigue at the foulant-membrane interface caused by the deformation of the membrane and contact with a spacer in contact with the membrane.

Abstract: A responsive material having an elastomeric matrix in which ferromagnetic particles are dispersed so as to have a predetermined magnetization pattern which, when exposed to an external magnetic field, changes the shape of the responsive material from an initial shape to a predetermined transformed shape dictated by the magnetization pattern. An initial shape of the responsive material is formed by direct ink printing while applying magnetic fields to a dispensing nozzle to align the particles and gives rise to the desired magnetization pattern.

Abstract: A biorobotic hybrid heart that preserves organic intracardiac structures and mimics cardiac motion by image-guided replication of the cardiac myofiber architecture of the left ventricle with an active synthetic myocardium that drives the motion of the heart. The active soft tissue mimic is adhered to the organic endocardial tissue in a helical fashion using a custom-designed adhesive to form a flexible, conformable, and watertight organosynthetic interface.

Abstract: Adhesion of conducting polymers on diverse insulating and conductive substrates via a hydrophilic adhesion layer, where one or more functional groups may be disposed between the substrate and the hydrophilic adhesion layer. Adhesion of the conducting polymers on the substrates is such that adhesion is maintained or substantially maintained in wet physiological environments.

Abstract: A dry shape memory adhesive material for adhering a target surface in the presence of fluid and for providing tunable mechanical contraction of an adhered surface. The dry shape memory adhesive material is pre-stretched and dried to provide an adhesive structure that implements a hydration-based shape memory mechanism to achieve both uniaxial and biaxial contractions of the adhered surface. According to preferred embodiments, the shape memory adhesive material includes a combination of one or more hydrophilic polymers or copolymers, one or more amine coupling group, and one or more cross linkers.

Abstract: An adhesive material that provides fast and robust adhesion on wet surfaces, where the adhesion formed is detachable on-demand. The adhesive material is formed of one or more hydrophilic polymers or copolymers grafted with one or more amine coupling groups via a plurality of cleavable physical bonds and/or cleavable covalent bonds and one or more cross linkers. Application of the adhesive material on a wet surface causes the adhesive material to absorb liquid to thereby swell the adhesive material to form a layer of hydrogel, resulting in the formation of temporary crosslinks followed by covalent crosslinks with the surface. Introducing a triggering agent cleaves the cleavable physical bonds and/or cleavable covalent bonds to allow for non-traumatic detachment of the adhesive material from the surface.
