    摘要： Superabsorbent material treated to resist damage when subjected to an Absorbent Product Processing Simulation Test, which simulates the mechanical damage that occurs during current commercial diaper manufacturing processes. The treated superabsorbent material has a centrifuge retention capacity of about 15 grams or greater of 0.9 weight percent sodium chloride per gram of the superabsorbent material and a gel bed permeability (GBP) at 0 psi swell pressure on pre-screened particles of about 200 (×10−9 cm2) or greater. After subjecting the treated superabsorbent material to the Absorbent Product Processing Simulation Test, the treated superabsorbent may exhibit minimal reduction in GBP of pre-screened or un-screened particles at 0 psi or at 0.3 psi swell pressure, as well as possibly exhibiting minimal reduction in average particle size diameter (PSD). The superabsorbent material can be treated by adding an aqueous solution of a hydrophilic soft polymer to the superabsorbent material, mixing the superabsorbent material with the aqueous solution, and drying the superabsorbent material.

    摘要： An article comprises a stretchable absorbent composite (30) that includes a quantity of superabsorbent particles (32) which are operatively contained within a matrix of elastomeric polymer fibers (34). In particular aspects, the composite article can include at least about 60 wt % of the superabsorbent particles and not more than about 40 wt % of the elastomeric polymer fibers, based on a total weight of the composite. In other aspects, the composite article can provide a high stretchability. Additional aspects can provide a low shake-out. Particular configurations can, for example, provide a stretchability value of at least about 30%. Additional aspects can include a configuration that provides a shake-out value of not more than about 2%. In other aspects, the invention can provide a shake-out value of not more than about 1.2%. In further aspects, the absorbent composite can include superabsorbent particles having a coating of treatment-material that is thermally processible. Additional aspects can include a treatment-material which is water soluble.

    摘要： An absorbent composition includes absorbent material, such as superabsorbent material, surface-treated with at least two different compatible agents. The superabsorbent material may be coated with multiple surface treatment agents in such a manner that each of the surface treatment agents is exposed on a surface of the superabsorbent material. For example, one surface treatment agent may be in a liquid coating form and another surface treatment agent may be in a powder form, each applied separately to the superabsorbent material.

    摘要： A method of estimating a concentration of DNA molecules in a biological sample includes storing a number of a plurality of reaction sites in a memory and distributing the biological sample among the plurality of reaction sites. The method also includes determining a number of the plurality of reaction sites characterized by a presence of one or more of the DNA molecules and computing a portion of the plurality of reaction sites characterized by the presence of the one or more of the DNA molecules. The method further includes estimating the concentration of the DNA molecules as a function of the portion of the plurality of reaction sites and computing a confidence interval for the estimated concentration of DNA molecules.

    摘要： An absorbent material formed at least in part of a crosslinked polymer. The absorbent material has a centrifuge retention capacity as determined by a Centrifuge Retention Capacity Test of at least about 20 g/g and a gel bed permeability under load as determined by a Gel Bed Permeability Under Load Test of at least about 300×10−9 cm2 or a free swell gel bed permeability as determined by a Free Swell Gel Bed Permeability Test of at least about 2,500×10−9 cm2. The crosslinked polymer may comprise either at least about 75 weight percent anionic polymer or at least about 75 weight percent cationic polymer. In one embodiment, the cross-linked polymer is surface treated with a water soluble non-cross-linked polymer having a potential for becoming charged opposite that of the cross-linked polymer.
