By combining various metal clusters with different interconnecting organic linkers, the pore structure, crystallinity, as well as the surface properties can be modified. In the present work, modification of the organic linker molecules is utilized to synthesize CAU-10 type MOFs with variable affinity of the pore surface to water. In principle, this should influence the accessibility of the pores for water vapor and therefore offer a tool to control its sorption properties. For a deeper understanding we studied the water sorption characteristics and compared the results to the conductive and dielectric properties studied by impedance spectroscopy. Spectra in a wide frequency range from 1 mHz to 1 MHz were recorded. Data analysis is performed using the Havriliak–Negami model. The MOFs are also tested as sensitive layers for capacitive humidity sensing by correlating the change in permittivity of the materials with the amount of physisorbed water. Such an MOF-based sensor was tested with respect to environmental monitoring and compared to a commonly used commercial humidity sensor.}}, author = {{Weiss, Alexander and Reimer, Nele and Stock, Norbert and Tiemann, Michael and Wagner, Thorsten}}, issn = {{1463-9076}}, journal = {{Physical Chemistry Chemical Physics}}, pages = {{21634--21642}}, title = {{{Surface-modified CAU-10 MOF materials as humidity sensors: impedance spectroscopic study on water uptake}}}, doi = {{10.1039/c5cp01988e}}, year = {{2015}}, } @article{25939, abstract = {{A variety of metal nitrates were filled into the pores of an ordered mesoporous CMK-3 carbon matrix by solution-based impregnation.

This study aims to monitor the thermally induced processes by thermogravimetric analysis (TGA), coupled with mass ion detection (MS). The highly dispersed metal nitrates in the pores of the carbon matrix tend to react to the respective metal oxides at lower temperature than reported in the literature for pure, i.e., carbon-free, metal nitrates. The subsequent thermal combustion of the CMK-3 carbon matrix also occurs at lower temperature, which is explained by a catalytic effect of the metal oxides present in the pores.

In particular, higher electron mobilities are observed in n-doped samples with monoclinic strain along the [110] direction, and experimental evidence relates this to changes in the effective mass as well as the scattering rates. To assess the relative importance of these two factors, we combine density-functional theory in the local-density approximation with the GW approximation for the electronic self-energy and investigate the effect of uniaxial and biaxial strains along the [110] direction on the structural and electronic properties of Si. Longitudinal and transverse components of the electron effective mass as a function of the strain are derived from fits to the quasiparticle band structure and a diagonalization of the full effective-mass tensor. The changes in the effective masses and the energy splitting of the conduction-band valleys for uniaxial and biaxial strains as well as their impact on the electron mobility are analyzed. The self-energy corrections within GW lead to band gaps in excellent agreement with experimental measurements and slightly larger effective masses than in the local-density approximation.}}, author = {{Bouhassoune, Mohammed and Schindlmayr, Arno}}, issn = {{1687-8124}}, journal = {{Advances in Condensed Matter Physics}}, publisher = {{Hindawi}}, title = {{{Ab initio study of strain effects on the quasiparticle bands and effective masses in silicon}}}, doi = {{10.1155/2015/453125}}, volume = {{2015}}, year = {{2015}}, } @article{43250, abstract = {{We present radiation mechanism exhibited by a higher order soliton.
