Growth, nutrient balance, plasma ammonia levels and urinary p-cresol excretion were evaluated in growing pigs fed diets containing various levels of zeolite A or clinoptilolite. In one growth trial, crossbred pigs averaging 25 kg initial body weight were assigned to diets containing no zeolite, .3% zeolite A or .5% clinoptilolite for a 6-wk growing phase trial. Average daily gain (ADG), average...

In this work, low-cost and high permeation NaA zeolite membrane was successfully prepared on kaolinite support by in-situ crystallization using secondary growth method. The effect of synthesis conditions including temperature time crystallization, water ratio studied aiming to improve the quality performance membrane. thoroughly characterized many techniques such as X-ray diffraction, scanning ...

In the Introduction section of this Research Article, description on membrane geometry was incorrect. The first sentence fourth paragraph in section, “Herein we prepared high-silica CHA zeolite membranes ceramic hollow fiber substrates for Kr/Xe separation.” should be revised to read disk This change does not affect interpretation data and conclusions, but guarantees a consistent with other sec...

Novel nanocomposites consisting of a water-soluble acrylamide-based photopolymer and colloidal zeolite nanoparticles of zeolite Beta and zeolite A were prepared. The interactions between the photopolymer components and zeolite nanoparticles in the photopolymerizable nanocomposites were characterized for the first time by (13)C nuclear magnetic resonance and visible spectroscopy. It was found th...

UNLABELLED The influence of natural zeolite on biogenic amines (BAs) and ammonia (AMN) production by eight common gram negative and positive foodborne pathogens (FBP) were investigated in histidine decarboxylase broth (HDB). Presence of 1% zeolite in the HDB resulted in significantly higher AMN production. Histamine (HIS) production by gram positive bacteria was as low as 0.5 mg/L, whereas Esch...

A preferentially oriented mordenite membrane was successfully prepared on a seeded porous a-alumina support. Characterization results of XRD (X-ray diffractometer) and FE-SEM (field emission scanning electron microscope) revealed that evolutionary selection might predominantly contribute to the formation of the sharply oriented mordenite membrane. The necessary conditions under which evolutiona...

This article reported a novel low-temperature process for aromatics production through lignin depolymerization catalyzed by 0.1 wt% Pd-zeolite Y catalyst prepared by a facile method. Under the same reactive condition, the as-prepared Pd-zeolite Y catalysts exhibited much higher catalytic efficiency than zeolite Y or commercial Pd/Al2O3–zeolite composites. The selectivity of the Pd-zeolite Y tow...

Iron incorporated zeolites were prepared from Na-A type zeolite synthesized from melting slag and FeCl3 solution and applied as adsorbents for NH3 and H2S gases. Iron incorporated zeolite was pelletized, calcined and used for gas adsorption experiment. XRD analyses of the zeolite revealed that Fe3þ concentration of solution more than 90mM could destruct the zeolite network structure. It was obs...

A fiber optic intrinsic Fabry-Perot interferometric (IFPI) chemical sensor was developed by fine-polishing a thin layer of polycrystalline nanoporous MFI zeolite synthesized on the cleaved endface of a single mode fiber. The sensor operated by monitoring the optical thickness changes of the zeolite thin film caused by the adsorption of organic molecules into the zeolite channels. The optical th...
