    摘要: A process for postcrosslinking a water-absorbing polymer comprises said polymer being treated with a postcrosslinker and, during or after said treating, being postcrosslinked and dried by temperature elevation, said postcrosslinker being a compound of the formula I where R1, R2, R3, R4, R5, R6, R7, R8 and R9 are each independently hydrogen, C1-C12-alkyl, C2-C12-alkenyl or C6-C12-aryl, wherein C1-C12-alkyl, C2-C12-alkenyl or C6-C12-aryl may be halogen substituted. The liquid-absorbing polymers are useful in hygiene articles and packaging materials.

    摘要: A nanovolume microcapillary crystallization system allows nanoliter-volume screening of crystallization conditions in a crystal card that allows crystals to either be removed for traditional cryoprotection or in situ X-ray diffraction studies on protein crystals that grow within. The system integrates formulation of crystallization cocktails with preparation of the crystallization experiments. The system allows the researcher to select either gradient screening in crystallization experiments for efficient exploration of crystallization phase space or a combination of sparse matrix with gradient screening to execute one comprehensive hybrid crystallization trial.

    摘要: Foams and methods of using foams for fighting fires in confined areas (i.e., mine shafts) are provided. In one embodiment, a foam for extinguishing a fire is provided. The foam includes a surfactant; a non-flammable liquid; and an inert gas having a density substantially less than air. Preferably, the density of the foam is substantially less than the density of air. The light foam will allow a basic form of directional control of the foam because the light foam will float towards the ceiling of a cavern or mine shaft. This offers fire fighters several options in extinguishing an underground fire.
