For the first time a metal hydride has been used for the preparation of a metal-organic framework. MIL-78 has been synthesized by the solid-state mechanochemical reaction between yttrium hydride and trimesic acid. The process does not involve solvents and does not generate liquid by-products, thus proving the viability of the solid-state approach to the(More)
The aim of this paper is to study the distribution of adult migrants from the household. The inflated Poisson-Lindley distribution is found to be a suitable model to describe this distribution. The parameters of this distribution have been estimated by two methods and suitability of model is checked by using real data sets. Findings may help planners and(More)
The mechanism of thermochemical dehydrogenation of the 1:3 mixture of Li(3)AlH(6) and NH(3)BH(3) (AB) has been studied by the extensive use of solid-state NMR spectroscopy and theoretical calculations. The activation energy for the dehydrogenation is estimated to be 110 kJ mol(-1), which is lower than for pristine AB (184 kJ mol(-1)). The major hydrogen(More)

The magnetization of the oriented Er5Si4 single crystal, measured along the three principal crystallographic directions, reveals strong magnetocrystalline anisotropy. The b axis is the easy magnetization direction. The possible presence of the crystal-field effect and the noncollinear alignment of magnetic moments result in a lower than g J magnetization(More)
