Self-assembly of chromophores nanoconfined in porous materials such as zeolite L has led to technologically relevant host-guest systems exploited in solar energy harvesting, photonics, nanodiagnostics and information technology. The response of these hybrid materials to compression, which would be crucial to enhance their application range, has never been explored to date. By a joint high-press...

background: there are great resources of natural zeolite in iran. zeolite, an inorganic ion-exchanger, may be used as a suitable technical-economical solution for water treatment in many regions of iran. in this study, the characterization of natural zeolite natrolite and the feasibility of removing hardness, cations, and anions were investigated. methods: first, zeolite composition and type we...

besides human dental and skeletal fluorosis, drinking water above permissible levels of fluoride is known to cause a wide range of adverse health effects. in this study, the adsorption of fluoride from aqueous solution onto pretreated zeolite has been studied by using batch test. the large surface area of natural zeolite (i. e., clinoptilolite from miyaneh region, iran) was utilized to create a...

Large-pore microporous materials are of great interest to process bulky hydrocarbon and biomass-derived molecules. ITQ-27 (IWV) has a two-dimensional pore system bounded by 12-membered rings (MRs) that lead to internal cross-sections containing 14 MRs. Investigations into the catalytic behavior of aluminosilicate (zeolite) materials with this framework structure have been limited until now due ...

in this paper we report synthesis of fe2tio5-5a zeolite (z5a) nanocomposites with 5%, 10% and 20% weight percent of fe2tio5 in 5a zeolite in stearic acid media after calcination of the gel samples obtained at 600-900°c for 2 hrs. the powder x-ray diffraction (xrd) patterns have been used for characterization of the prepared samples. the scanning electron microscopy (sem) images and x-ray energy...

The applicability of electro-Fenton technology to remediation of wastewater contaminated by several organic pollutants such as dyes and polycyclic aromatic hydrocarbons has been evaluated using iron-enriched zeolite as heterogeneous catalyst. The electro-Fenton technology is an advanced oxidation process that is efficient for the degradation of organic pollutants, but it suffers from the high o...

In this study, the suitability of zeolite as a possible medium for ammonium adsorption, desorption and recovery from wastewater was investigated. Specifically, batch adsorption studies with solutions enriched in NH$_4^+$ were conducted employing to evaluate how chemical treatment contact time affect desorption. Several experimental tests carried out considering both untreated treated zeolite. U...

Genus Leishmania is a protozoan parasite that causes different severe diseases. Fetal Calf Serum (FCS) is the major part of the Leishmania culture media, for mass cultivation and the most expensive ingredient in these media. In the present work, the efficacy of chicken serum was evaluated in Leishmania culture media. The results indicated that, the (10%) chicken serum enriched culture medium su...
