A direct comparison of quasielastic neutron scattering experimental measurements and molecular dynamics computer simulations is carried out for the first time for hydrogen and deuterium confined in the nanostructure of faujasite type zeolites at a temperature of 100 K, in order to investigate the dependence of sorption thermodynamics and sorbate dynamics on the sorbed phase concentration. The c...

1. Introduction Practical applications of zeolites and other nanoporous materials always involve at least two different components, but understanding of multicomponent diffusion in zeolites is limited and experimental data are scarce. The elements of the multicomponent Fickian diffusion tensor for a given system may depend on the total loading of adsorbed molecules, the adsorbed-phase compositi...

This paper discusses the unprecedented microscopic findings of micellar growth in colloidal system (CS) of catalyzed piperidinolysis of ionized phenyl salicylate (PS-). The giant vesicles (GV) was observed under the optical polarization microscope (OPM) at [NaX]=0.1M where X=3-isopropC6H4O-. The conditions were rationalized from pseudo-first-order rate constant, kobs of PS- of micellar phase at...

Artificial photonic antenna systems have been realised by incorporating organic dyes in a microporous material.[1] We have been using zeolite L in most of our experiments as it has proven to be a very versatile host material. Zeolite L crystals are cylindrically shaped, porous aluminosilicates featuring a hexagonal symmetry. The size and aspect ratio of the crystallites can be tuned over a wide...

The impact of the crystal size template zeolite on textural properties resulting Zeolite Templated Carbons was studied using nano- (20 nm) and micron-sized (5 μm) beta crystals. ZTCs were obtained for both crystals, yet sample presence supermicropores small mesopores detected, indicating a higher degree structural defects during templating process hence in final ZTC. insights gained from nitrog...

We report below on nuclear magnetic resonance investigations of the structure and exchange kinetics for the free acid, anion, sodium complex, and barium complex of the ionophore lasalocid A (X537A) in methanol solution. A comparison between the proton and carbon longitudinal relaxation times of lasalocid in nonpolar and polar solvents demonstrates that the free acid (HX) is a monomer in methano...
