    Making use of the preferred adsorption affinity and capacity to CO 2 as well as the highly porous structure with huge cavities of 2.4 nm, a highly permeable and selective ZIF-95 molecular sieve membrane was developed for ...
  • Kumar, P. Jeevan; Nishimura, K.; Senna, M.; Düvel, A.; Heitjans, Paul; Kawaguchi, T.; Sakamoto, N.; Wakiya, N.; Suzuki, H. (Cambridge : Royal Society of Chemistry, 2016)
    We present a novel approach to the solid-state synthesis of garnet-type cubic Li7La3Zr2O12 (c-LLZO) nanostructured particles with 1.0 mass% Al at 750 °C within 3 h. In contrast to conventional solid-state processes, a ...
  • Elgamal, M.Hani A.; Soliman, Hesham S.M.; Duddeck, Helmut; Mikhova, Bozhana; Gartmann, Martin (Berlin : De Gruyter, 1995)
    A novel C-28 tetraglycoside of quillaic acid (1) has been isolated from Gypsophila capillaris. The structure was elucidated by 1 D NMR (NOE difference, DEPT, selective13C{1H} INEPT), 2D NMR (1H,1H and1H,13C COSY,1H,1H,1H ...
  • Paleek, Jiri; Zweigerdt, Robert; Olmer, Ruth; Martin, Ulrich; Kirschning, Andreas; Dräger, Gerald (Cambridge : Royal Society of Chemistry, 2011)
    A practical synthesis of the Rho-Kinase inhibitor Y-27632 and two new fluoro derivatives was achieved in seven steps and with a good overall yield of 45% starting from commercially available (R)-1-phenylethylamine. Compared ...
  • Krüger, Christoph; Sato, Hiroki; Matsumoto, Takuto; Shiga, Takuya; Newton, Graham N.; Renz, Franz; Oshio, Hiroki (Cambridge : Royal Society of Chemistry, 2012)
    An asymmetric polycyanide iron complex, K2[Fe III(L1)(CN)4](MeOH) (HL1 = 2,2′-(1H-pyrazole-3,5- diyl)bis-pyridine), was synthesized and its complexation compatibility with nickel ions was examined. Two kinds of enantiomeric ...
  • Esparan, Vida; Krings, Ulrich; Struch, Marlene; Berger, Ralf Günter (Basel : MDPI AG, 2015)
    The symmetrical structure of curcumin includes two 4-hydroxy-3-methoxyphenyl substructures. Laccase catalyzed formation of a phenol radical, radical migration and oxygen insertion at the benzylic positions can result in ...
  • Springer, Sergej; Baburin, Igor A.; Heinemeyer, Thea; Schiffmann, Jan Gerrit; van Wüllen, Leo; Leoni, Stefano; Wiebcke, Michael (Cambridge : Royal Society of Chemistry, 2016)
    We show via structural considerations and DFT calculations that for a zeolitic imidazolate framework (ZIF) with sodalite (SOD) topology, [Zn(dcim)2]-SOD (dcim = 4,5-dichloroimidazolate), structural models of an infinite ...
  • Schieid, Thomas; Lissner, Falk (Berlin : De Gruyter, 1996)
    The oxidation of reduced chlorides (MCl2) or chloride-hydrides (MClHx) of the lanthanides with sulfur (700-850°C, 7 d, sealed tantalum capsules or evacuated silica vessels) usually results in the formation of the sesquisulfides ...
  • Indris, Sylvio; Heitjans, Paul; Ulrich, Markus; Bunde, Armin (Berlin : Walter de Gruyter, 2005)
