    Abstract: Compositions and methods for making a composition comprising a plurality of polymeric chelator particles comprising a plurality of cross-linked polyamine polymer backbone chains and one or more chelators covalently coupled thereto, wherein at least 90% of the plurality of the polymeric chelator particles have a particle size of 300 μm or less. Also disclosed are methods of using the composition, e.g., for removing metal from a medium or treating iron overload disease.

    Abstract: The invention is directed to stable and labile crosslinked water swellable polymeric microparticles that can be further gelled, methods for making same, and their various uses in the hygiene and medical arts, gel electrophoresis, packaging, agriculture, the cable industry, information technology, in the food industry, papermaking, use as flocculation aids, and the like. More particularly, the invention relates to a composition comprising expandable polymeric microparticles having labile crosslinkers and stable crosslinkers, said microparticle mixed with a fluid and an unreacted tertiary crosslinker comprising PEI or other polyamine based tertiary crosslinker that is capable of further crosslinking the microparticle on degradation of the labile crosslinker and swelling of the particle, so as to form a stable gel. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric microparticles are injected into a well and when the heat and/or pH of the well cause degradation of the labile crosslinker and when the microparticle expands, the tertiary crosslinker crosslinks the polymer to form a stable gel, thus diverting water to lower permeability regions and improving oil recovery.

    Abstract: The instant application relates to nanogels or compositions that hold multivalent metal ions until some level of nanogel degradation has occurred, then slowly release the multivalent metal ions for gelation with carboxylate containing polymers. Compositions comprising such nanogels, together with polymers that can be crosslinked with multivalent metal ions, allow the deployment of such mixtures in various applications, and greatly increased gelation times.

    Abstract: Described herein are magnetic sensors (e.g., force sensors) as well as methods of making and using thereof The magnetic sensors can employ a soft magnetic composite (e.g a composite comprising a population of magnetic particles dispersed within an elastomeric resin) paired with a magnetometer. These sensors can overcome many of the traditional shortcomings that have hampered the effectiveness of existing compression sensors in certain applications, including large size, a lack of 3-dimensional sensing capacity, need for sensors to incorporate rigid components, and/or signal quality issues associated with the orientation or deformation of soft composites under compression.
