Abstract: Techniques for chemically recycling cellulose waste such as cotton are disclosed herein. In one embodiment, a method includes hydrolyzing a cotton waste and dissolving cellulose in the hydrolyzed cotton waste in an aqueous solution containing an alkali and one or more of urea ((NH2)2CO), polyethylene glycol, or thiourea (SC(NH2)2) to produce another aqueous solution containing dissolved cellulose. Then the another aqueous solution containing the dissolved cellulose can be extruded into a coagulation bath to coalesce the dissolved cellulose in the extruded solution, thereby reforming the dissolved cellulose from the cotton waste into a regenerated fiber.

Abstract: A patient fluid absorption and estimation device includes an absorbent layer comprising an absorbent material and adapted to absorb fluids. The device's sensing layer includes piezoresistive element(s). The sensing layer abuts the absorbent layer such that changes in at the mass or shape of the absorbent layer cause a change in the strain in the piezoresistive element(s). The device includes memory and processing in communication with the memory. The processing includes a piezoresistive element interface. The processing senses a voltage, representing an estimation of the amount of fluid absorbed, across each element via the interface. The processing then converts each voltage to a digital value, and stores the value in the memory. The device includes wireless communications that receives commands from an external computer system to transmit the values, and transmits the values to the external. A power subsystem powers each subsystem.
