Elucidation of Adsorbate Structures and Interactions on Brønsted Acid Sites in H-ZSM-5 by Synchrotron X-ray Powder Diffraction.
Microporous H-ZSM-5 containing one Brønsted acid site per asymmetric unit is deliberately chosen to host pyridine, methanol, and ammonia as guest molecules. By using new-generation in situ synchrotron X-ray powder diffraction combined with Rietveld refinement, the slight but significant alteration in scattering parameters of framework atoms modified by the guest molecules enables the user to el...
متن کاملClarithromycin form I determined by synchrotron X-ray powder diffraction.
The structure of the metastable form I polymorph of the macrolide antibiotic clarithromycin, C(38)H(69)NO(13), was determined by a powder diffraction method using synchrotron radiation. The space group of form I is P2(1)2(1)2. The initial model was determined by a molecular replacement method using the structure of clarithromycin form 0 as a search model, and the final structure was obtained th...
متن کاملPropene adsorption sites in zeolite ITQ-12: a combined synchrotron X-ray and neutron diffraction study.
The adsorption site of propene in the small-pore, pure silica zeolite [Si24O48]-ITW-ITQ-12 has been characterized via Rietveld refinement of the crystal structure of propene-loaded ITQ-12 on the basis of synchrotron X-ray and neutron diffraction data taken at 298 K. The structure can be described with a monoclinic unit cell having Cm symmetry and unit cell parameters a = 10.436 angstroms, b = 1...
متن کاملSr–fresnoite determined from synchrotron X-ray powder diffraction data
The fresnoite-type compound Sr2TiO(Si2O7), distrontium oxidotitanium disilicate, has been prepared by high-temperature solid-state synthesis. The results of a Rietveld refinement study, based on high-resolution synchrotron X-ray powder diffraction data, show that the title compound crystallizes in the space group P4bm and adopts the structure of other fresnoite-type mineral samples with general...
متن کاملLaser and synchrotron radiation pump–probe x-ray diffraction experiments
Recent developments have allowed x-ray diffraction techniques at synchrotron radiation facilities to be employed with a temporal resolution of around 1 ps. These developments are the availability of firstly, high brightness third-generation x-ray sources, secondly, passively mode-locked lasers with 100 fs temporal duration and thirdly, averaging streak cameras with sub-picosecond temporal resol...
