On the microporous nature of transition metal nitroprussides

Article Abstract:

Stable phases of nitroprussides of divalent transition metals forming a family of microporous materials with three typical crystal structures and behaviors are investigated. The stable phases of this family of materials belong to following crystal structures, orthorhombic (Pnma) (Mn(super 2+), Fe(super 2+), Zn(super 2+), and Cd(super 2+)), cubic (Fm3m) (Co(super 2+) and Ni (super 2+)) and orthorhombic (Amm2) (Cu(super 2+))

An analytical approach to determine the pore shape and size of MCM-41 materials from X-ray diffraction data

Article Abstract:

The pore shape and size of MCM-41 are studied analytically by comparing the observed powder X-ray diffraction intensities with that derived from the MCM-41 crystal structure models, with two different pore shapes, a hexagon and a circle. The pore size and boundary obtained from this approach has agreed well with those obtained from an [N.sub.2] gas adsorption measurement combined with the Fourier synthesized density map.

Quantitative analysis of the electrostatic potential in rock-salt crystals using accurate electron diffraction data

Article Abstract:

The experiments were done where improved transmission electron-diffraction technique were used in quantitative study of the electrostatic potentials in LiF, NaF, and MgO crystals. The results show the suitability of electron diffraction for determination of the core-electron binding energy.
