  • Patent number: 8785348
    Abstract: The present disclosure relates to a method and apparatus for separating nucleic acids. A carrier may include a porous microbead having cation-exchangeable groups attached to the surface of the porous microbead. Capturing chains modified with positively charged functional groups and having a base sequence complementary to a target nucleic acid chain sequence are immobilized on to the surface of the porous microbead. In various embodiments, capturing chains are immobilized on to the surface of the porous microbead through an ion exchange bond or a covalent bond with the cation-exchangeable groups of the porous microbead. In some cases, the porous microbead has a number of through pores adapted to permit a solution to pass rapidly through the through pores and a number of diffusive pores adapted to permit a solute of the solution to diffuse into the diffusive pores.

  • Patent number: 8454912
    Abstract: Disclosed herein is an radioisotope adsorbent including a bifunctional organosilane compound, including an organosiloxane functional group and a phosphate group, bonded on the surface of silica which is a bone structure of the adsorbent, and a method of preparing the radioisotope adsorbent, and a strontium/yttrium generator using the radioisotope adsorbent. Since the radioisotope adsorbent has a high adsorption capacity for 90Y such as 95% extraction efficiency or more from ICi 90Sr/90Y by using a column packed with 0.4 g of the adsorbent with a high-purity of 90Y, it can be usefully to be employed in the fields requiring 90Y.

    Abstract: Compositions and methods for producing a manufactured product, a method for making a liquid absorbent, and processes for disposal of flammable liquids with a flue gas desulfurization by-product. The compositions for the manufactured products combine a binder and the by-product. The composition contains a greater percentage by weight of the by-product than the binder. The methods for producing manufactured products include dewatering the gypsum-depleted waste stream to reduce a water content, and forming the manufactured product. The method for making a liquid absorbent includes dewatering, granulating, drying, heating, and packaging a granulated gypsum-depleted composition as the liquid absorbent. The processes for disposal of flammable liquids include distributing a by-product into contact with flammable liquid, absorbing the liquid, transporting, and igniting the flammable liquid. The artificial soils are a combination of by-product and animal waste.
