  • Patent number: 6608228
    Abstract: Disclosed are highly efficient multiphoton absorbing compounds and methods of their use. The compounds generally include a bridge of pi-conjugated bonds connecting electron donating groups or electron accepting groups. The bridge may be substituted with a variety of substituents as well. Solubility, lipophilicity, absorption maxima and other characteristics of the compounds may be tailored by changing the electron donating groups or electron accepting groups, the substituents attached to or the length of the pi-conjugated bridge. Numerous photophysical and photochemical methods are enabled by converting these compounds to electronically excited states upon simultaneous absorption of at least two photons of radiation. The compounds have large two-photon or higher-order absorptivities such that upon absorption, one or more Lewis acidic species, Lewis basic species, radical species or ionic species are formed.

  • Patent number: 6603054
    Abstract: Disclosed is a fibrous absorbent structure that is wet stable and has large void volume with a density below the critical density of the fiber employed. In one embodiment, the fibrous absorbent uses open-celled foam technologies to keep the fibrous structure expanded and bonded. In other embodiments, the resulting fibrous structure resembles an open-celled polymeric foam, with fibers serving as struts stabilized by binder material. In another embodiment, the resulting fibrous structure is filled with hydrophilic open-celled foams with the cell size substantially smaller than the fibrous pores. Such a wet-stable, high void volume fibrous absorbent can be used in a disposable product intended for the absorption of fluid such as body fluid, including extensible absorbent articles.

  • Patent number: 6582574
    Abstract: pK-matched buffers, each containing two effective buffering components: one weak base and one weak acid which have similar pKa at 25° C. (within 0.3 pK units On agarose gels, the buffers in various concentrations were tested for separation of double-stranded DNA fragments with various DNA markers, agarose gel concentrations, and field strengths. Mobility was inversely proportional to the logarithm of molecular weight. The buffers provided high resolution without smearing at more dilute concentration than is possible with standard TAE (Tris/Acetate, pH 8.0) or TBE (Tris/Borate, pH 8.3) buffers. The buffers were also tested in 7M urea denaturing LongRanger™ sequencing gels and in non-denaturing polyacrylamide SSCP gels. The pK-matched buffers provide good separation and high resolution, at a broad range of potential pH values.
