The commercial SAPO-34 zeolite with 0.38 nm pore size and ZIF-8 particles 0.34 aperture were separately dispersed into different polymer matrix, to prepare the mixed matrix membranes (MMMs) for gas separation. situation of in influence fillers on separation performance membrane had been investigated this study. as-synthesized MMMs showed a better trade-off between permeability selectivity than ...

Global climatic change leads to many detrimental effects on all life forms. Outstanding case, salinity, and drought are considered multidimensional stress that severely affect plant growth sustainable agriculture. Thymus vulgaris is a medicinal has phytochemical constituents, it threatened by several abiotic stresses caused climate change. Therefore, the present study aims evaluate physiologica...

Pervaporation (PV) dehydration of isopropanol (IPA) using modified chitosan membranes was studied. The membranes were prepared from chitosan and were modified by using zeolite-A. Pre-weighed amount of zeolite-A was added into acidic solvent and stirred to produce homogeneous solution. Chitosan flakes were then added into the solution and stirred overnight. Various ratios of zeolite-A and chitos...

The use of doses higher than 500 g of Zeolite leads to a dramatic depression of feed intake. Even the effective dose reduces feed intake and induces hypophosphataemia; however, these effects are considered transient. Zeolite may reduce serum Mg but this is without physiological significance. Serum levels of copper and zinc as well as milk yield and composition are not affected by Zeolite treatm...

Hitherto zeolite formation has not been fully understood. Although electrochemical impedance spectroscopy has proven to be a versatile tool for characterizing ionic solutions, it was never used for monitoring zeolite growth. We show here that EIS can quantitatively monitor zeolite formation, especially during crucial early steps where other methods fall short.

The antibacterial activity of natural zeolite (CLI) containing 2.60 wt. % Cu 2+ (Cu-CLI) or 5.07 wt.% Ag + (Ag-CLI) were tested against clinical isolates of Acinetobacter baumannii. A. baumannii belonging to the European clone I and II were isolated in Split University Hospital, Croatia. The isolate from clone II was more sensitive on the effect of the metalloaded zeolite than isolate of clone ...

A d-dimensional zeolite is a d-dimensional body-and-pin framework with a (d+1)-regular underlying graph G. That is, each body of the zeolite is incident with d+1 pins and each pin belongs to exactly two bodies. The corresponding d-dimensional combinatorial zeolite is a bar-and-joint framework whose graph is the line graph of G. We show that a two-dimensional combinatorial zeolite is generically...
