  • Patent number: 11766366
    Abstract: Absorbent articles with biodegradable and/or biocompostable elements are disclosed, wherein the absorbent articles include sensors. The sensors detect and determine variables associated with collected fluids, solids, and gases, including a presence of fluids, solids, and gases, a volume of fluids, solids, and gases, and/or a distribution of fluids, solids, and gases. In one embodiment, the sensors and/or connected computing systems are calibrated to capacities and other properties of elements within the articles, including superabsorbent polymers, and are operable to trigger an alert based on detected or determined conditions.

  • Publication number: 20230138358
    Abstract: Provided herein are coated particles, such as, for example, proppants comprising a coating. A coated particle of the present invention may swell upon contact with a solution having a salinity in a range of about 50 ppm to about 100,000 ppm and/or having a hardness in a range of about 1 ppm to about 150,000 ppm. The amount of swelling may vary by less than 50% over a salinity concentration in a range of about 50 ppm to about 100,000 ppm and/or a hardness concentration in a range of about 1 ppm to about 150,000 ppm. Also provided herein are methods of making coated particles and methods of using the same.

  • Publication number: 20210290452
    Abstract: A system for treating used hygienic articles including soiled or swollen superabsorbent materials (SAMs). The portion of the article including the soiled or swollen SAM is treated with a chemical which restructures or degrades the soiled or swollen SAM so that the products of the reaction are easily disposable in a method alternative to trash disposal and landfilling, including through municipal treatment where the products of the reaction do not clog a standard toilet or standard plumbing. Hygienic articles include baby diapers, adult diapers, incontinence pads, menstrual pads, or any other article which includes one or more SAMs.
