photochromic nature of azo moiety and pyridine radicals, two photochromic MOFs, namely [M(H2O) (azpy)0.5 (mal)]·0.25azpy (M = Zn for 1 and Mn for 2, azpy = azopyridine, H2mal = malonic acid) have been constructed. MOFs 1 and 2 exhibit 3D porous frameworks with ins topology. Both of the compounds features trans-cis isomerization of the azpy molecule as well as the formation of pyridine based radicals with

The hydrazinium(1+) metal acetates and malonate dihydrates of the molecular formula [(N2H5)(2)M(CH3COO)(4)] and (N2H5)(2)[M(OOCCH2COO)(2)(H2O)(2)] respectively, where M = Co, Ni or Zn, have been prepared and characterized by chemical analyses, conductance, magnetic, spectral, thermal and X-ray powder diffraction studies. The magnetic moments and electronic spectra indicate that these complexes are of high-spin octahedral variety. The infrared spectra show that the hydrazinium ions are coordinated in the case of acetate complexes, whereas in the malonate complexes the hydrazinium ions are out side the coordination sphere. These complexes undergo exothermic decomposition in the temperature range 150-450 degrees C to give the respective metal oxide as the final residue. The X-ray powder diffraction patterns of the malonate complexes indicate isomorphism among them.
A sub-ppm level formaldehyde gas sensor based on Zn-doped NiO prepared by a co-precipitation route
prepared by a controlled coprecipitation in aqueous solution. The phase identification, the texture, the morphologies and the chemical composition (including the chemical state of Zn and Ni) for all the samples were investigated by a set of techniques such as XRD, BET, SEM and XPS respectively. The comparison of the gas-sensing properties towards formaldehyde of the undoped NiO and the Zn-doped NiO was also
