[ 1 ] - Role of gel aging in template-free synthesis of micro and nano-crystalline sodalites

A facile effective stirring aging at room temperature prior to conventional hydrothermal treatment was employed in the template-free synthesis of micro- and nano-crystalline sodalites with two different initial gel compositions. The effect of initial Si/Al molar ratio, NaOH concentration and stirring aging time were investigated on the morphology and particle size of the...

[ 2 ] - Investigation of molecular motion of Cl-adamantane in the nanoprous zeolite by 13C NMR dipolar dephasing and variable contact time measurements

Dipolar-dephasing method provides some information about the strength of dipolar coupling in solids. Dipolar dephasing technique measures the time for a polarized carbon nucleus to lose its magnetization once the proton locking field is terminated. The dynamics of guest molecules adsorbed within the cavities and channels of nonporouszeolite strongly depend on the structure and chemical composit...
