The north western part of volcano-sedimentary complex of Davazdah-Emam mountain in north of Central Iran is located about 135 km SE Tehran. The Eocene to Oligocene volcanic rocks and dikes of intermediate to mainly basic of complex under the influence of hydrothermal fluids, probably associated with the involvement of meteoric water, experienced different degrees of alteration. The alteration o...
The chabazite-type silicoaluminophosphate SAPO-34 is a promising adsorbent for applications in thermal energy storage using water adsorption-desorption cycles. In order to develop a microscopic understanding of the impact of local heterogeneities and defects on the water adsorption properties, the interaction of different models of SAPO-34 with water was studied using dispersion-corrected densi...
The complexation of NiCl2 with 2,2?-Bipyridine was followed using quasielastic neutron scattering to observe reaction progress. Water adsorption in chabazite time resolution observed strain induced the aluminosilicate framework a high-resolution engineering diffractometer. These reactions illustrate recent progress and possibilities probes realistic catalytic as they
Using a combination of solid-state NMR spectroscopy, powder X-ray diffraction (pXRD), thermogravimetry, and periodic density functional theory (DFT) calculations, we investigate the calcination chabazite-type gallophosphate, GaPO-34, prepared with either 1-methylimidazole (mim) or pyridine (py) as structure-directing agent (SDA) fluoride charge-balancing anion. We demonstrate that, prior to SDA...
