synthesized and characterized by H-1, C-13, P-31 NMR and IR spectroscopies. The reaction of MnCl2 center dot 4H(2)O with L led to the formation of a new 3D system {MnL2Cl2}(n)center dot 34CH(3)OH (C-1). X-ray crystallographic data revealed that the ligand ...
The metal-org. frameworks M2(dobdc) (dobdc4- = 2,5-dioxido-1,4-benzenedicarboxylate, MOF-74, CPO-27) (M = Mg, Mn, Fe, Co, Ni, Zn) have shown considerable promise for a no. of gas storage and sepn. applications. These have included CO2/N2, CO2/H2, O2/N2, an ...
Materials exhibiting reversible hydrogen adsorption with high gravimetric and volumetric capacities are sought for use in on-board storage systems of hydrogen fuel cell-powered vehicles. Microporous metal-org. frameworks with high internal surface areas ha ...
The computational elucidation and proper description of the ultrafast deactivation mechanisms of simple organic electronic units, such as thiophene and its oligomers, is as challenging as it is contentious. A comprehensive excited state dynamics analysis o ...
Six metal-org. frameworks of the M2(dobdc) (M = Mg, Mn, Fe, Co, Ni, Zn; dobdc4- = 2,5-dioxido-1,4-benzenedicarboxylate) structure type bind carbon monoxide reversibly and at high capacity. IR spectra indicate that, upon coordination of CO to the divalent m ...
Metal org. frameworks (MOFs) are cryst. materials that contain metal-ions or metal-ion clusters as nodes and org. ligands as linkers to form 1-, 2-, and 3-D structures. In addn. to their convenient modular synthesis and chem. tunability, this class of mate ...
Functional nanostructured carbon materials, including two-dimensionally extended nanosheets, offer
intriguing perspectives for applications in emerging technologies such as hydrogen storage, lithium
storage, transition metal free catalysis, or solar abso ...
Results are presented that explore the dynamic structural changes occurring in two highly flexible nanocryst. metal-org. framework (MOF) compds. during the adsorption and desorption of pure gases and binary mixts. The Ni(1,2-bis(4-pyridyl)ethylene)[Ni(CN)4 ...
Resonant absorption can be used as a filter for high energy neutron spectroscopy. Here we report the transmission of eight thin foil filters: erbium, indium, iridium, dysprosium, hafnium, gadolinium, cadmium and samarium, measured using neutron time-of-fli ...
Reactions between gas molecules, e.g. H-2 and CO2 and solids take place at the surface. The electronic states and the local geometry of the atomic arrangement determine the energy of the adsorbate, i.e. the initial molecule and the transition state. Here w ...
