    Abstract: A 3D porous metal-organic framework and method of making are described. In some embodiments, a 3D porous metal-organic framework may be based on a trinodal (3,3,4) net of zyg topology by the self-assembly of the nonlinear hexacarboxylate (BHB) with the paddle-wheel Cu2(COO)4 cluster. Although its porosity and surface area are moderate, the open copper sites and optimal pore spaces enable the pore spaces to be fully utilized for methane storage, resulting in a high methane storage density and high absolute volumetric methane storage at room temperature and 35 bar. By the immobilization of high density open metal sites and the deliberate control of the pore space for their efficient methane storage, this porous MOF functions as an efficient media for methane and natural gas storage.

  • Patent number: 8357719
    Abstract: A drug having a muscle relaxing effect can be prepared by binding negatively charged gold nanoparticles having a size of 1.4 nm fitted to synaptic clefts to choline through ionic bonds, thereby inducing gold-sulfur bonds in the Cys loop of an acetylcholine receptor in neuromuscular junction, and thus blocking the electric current induced in signal transduction from a nerve to a muscle, thereby blocking neuromuscular transmission chemically and physically. When the reverse is administered after surgery, the gold-sulfur bonds are broken due to the re-flow of the electric current, and thus the gold nanoparticles are again released and metabolized into neuromuscular junction. Further, such muscle relaxing effect can be applied as an anticonvulsant.

  • Patent number: 8338327
    Abstract: An allyl acetate production catalyst comprising at least (a) palladium, (b) gold, (c) a compound containing at least one element selected from copper, nickel, zinc and cobalt, (d) an alkali metal salt compound and (e) a carrier, is produced by a process comprising step 1 in which a homogeneous solution of a palladium-containing compound and a gold-containing compound is supported on a carrier by contact therewith, step 2 in which the carrier obtained in step 1 is contacted with an alkali solution for impregnation, step 3 in which the carrier obtained in step 2 is subjected to reduction treatment, and step 4 in which a compound containing at least one element selected from copper, nickel, zinc and cobalt and an alkali metal salt compound are supported onto the carrier obtained in step 3. The obtained allyl acetate production catalyst has minimal reduction in activity and improved selectivity, when used for production of allyl acetate from propylene, oxygen and acetic acid.

  • Publication number: 20120295969
    Abstract: In order to achieve muscle relaxing effect and anti-atrial fibrillation effect, the present invention provides gold nanoparticles complexes. Gold nanoparticles complexes include negatively charged gold nanoparticles bound to choline or spermidine through ionic bonds according to the purpose to be achieved, which form gold nanoparticles-choline complexes or gold nanoparticles-spermidine complexes. The complexes migrate to an acetylcholine receptor and then the ionic bonds of the complexes are broken, thereby inducing gold-sulfur bonds in the Cys loop of an acetylcholine receptor, thus block the ionic path and achieve the effects.
