  • Patent number: 9751899
    Abstract: The direct depolymerization of biogenic and other high surface area silica sources uses both simple and hindered diols to produce alkoxysilanes in one or two steps that can be separated and purified directly from the reaction mixture by distillation, extraction or filtration followed by solution modification and distillation or extraction. The alkoxysilanes can take the form of spirosiloxanes or simple alkoxysilanes or oligomers thereof. Thereafter they can be treated with acid to produce colloidal or precipitated silica or aerosolized and combusted to provide fumed silica without the intervention of SiCl4.

  • Patent number: 8193350
    Abstract: A novel fluorescent compound having a high light fastness, high fluorescence quantum yield and sharp absorption spectrum, which emits fluorescence having a wavelength in long wavelength region, as well as its use as a labeling agent, is disclosed. In Formula [I] below, by forming a specific hetero ring(s) with R1 and R2, and/or R6 and R7, shift of the wavelength of the fluorescence to longer wavelength and increase in molar extinction coefficient are attained maintaining the high light fastness, high fluorescence quantum yield and sharp absorption spectrum which the fluorescent dyes having the boron dipyrromethene skeleton have.

  • Publication number: 20120130071
    Abstract: Platinum(II) complexes and the use of these complexes for oxidation of methane to methyl sulfate are disclosed, the catalyst having, as ligands, a network based on aromatic N-heterocycles which has at least 2 coordinative nitrogen atoms per platinum atom, and the complex anion is selected from a halide, hydrogensulfate, hydrogensulfite, sulfate, sulfite, methylsulfate, methanol, water, hydroxide, carbon monoxide, hydrogencarbonate and carbonate. The catalyst enables a selective low-temperature oxidation of methane to methyl sulfate or methanol. The catalysts not only exhibit high activity, but can also be removed easily from the reaction mixture and reused over several runs without significant loss of activity.

  • Publication number: 20120029167
    Abstract: A drug using the magnetic properties of a metal salen complex as represented by the following general formula in order to magnetize the intended drug by chemically binding the drug to a metal salen complex so that the drug can be delivered to the target diseased site. The drug can be delivered to the diseased site using the magnetic properties of the drug per se without using a carrier made of a magnetic substance as in the conventional methods.

  • Publication number: 20110252580
    Abstract: Embodiments herein provide a nanoparticle, such as a metal nanoparticle, coupled to a linker molecule to form a nanoparticle-linker construct. In an embodiment, a nanoparticle-linker construct may be further bound to a substrate to take advantage of one or more properties of the nanoparticle. In an embodiment, a functionalized nanoparticle (a nanoparticle having a reactive functionality) may be bound to a linker to form a functionalized nanoparticle-linker construct which may in-turn be bound to a substrate.
