  • Publication number: 20120065383
    Abstract: A process is provided that includes performing a high-temperature high-pressure hydrothermal treatment for a reaction liquid prepared as a mixture of an acylated inorganic fine particle precursor and an organic modifying agent that has a carboxyl group. Because the reaction liquid contains the acylated inorganic fine particle precursor in advance, the grain growth during the high-temperature high-pressure hydrothermal treatment can be suppressed. The process thus enables production of organic-modified inorganic fine particles of a size about the same as or even smaller than that before the high-temperature high-pressure hydrothermal treatment.

  • Publication number: 20110313147
    Abstract: Ion exchange and hydrophobic interaction chromatographic materials are constructed by tethering a terminal binding functionality to a solid support via a hydrophobic linker. The backbone of the linker typically comprises sulfur-containing moieties. Suitable terminal binding functionalities are tertiary amines, quaternary ammonium salts, or hydrophobic groups. These chromatographic materials possess both hydrophobic and ionic character under the conditions prescribed for their use. The separation of proteins from crude mixtures at physiological ionic strength can be accomplished with a chromatographic material of this type by applying pH or ionic strength gradients, thereby effecting protein adsorption and desorption.
