Using the chemical reduction method, silver nanoparticles (Ag NPs) were effectively synthesized into the zeolite framework in the absence of any heat treatment. Zeolite, silver nitrate, and sodium borohydride were used as an inorganic solid support, a silver precursor, and a chemical reduction agent, respectively. Silver ions were introduced into the porous zeolite lattice by an ion-exchange pa...

introduction: soil structural stability affects the profitability and sustainability of agricultural systems. particle size distribution (psd) and aggregate stability are the important characteristics of soil. aggregate stability has a significant impact on the development of the root system, water and carbon cycle and soil resistance against soil erosion. soil aggregate stability, defined as t...

Background & Aim: Aloe vera is used in the food and pharmaceutical as an aid to effective treatment. The purpose of this study is to improve growth, increase production of valuable metabolites and increase the sugars in Aloe vera gel with low cost and high efficiency under water stress conditions. Experimental: In this study, Aloe vera potted in greenhouse conditions...

GIS-NaP1 zeolite samples were synthesized using seven different Si/Al ratios (5-11) of the hydrothermal reaction mixtures having chemical composition Al2O3:xSiO2:14Na2O:840H2O to study the impact of Si/Al molar ratio on the water vapour adsorption potential, phase purity, morphology and crystal size of as-synthesized GIS-NaP1 zeolite crystals. The X-ray diffraction (XRD) observations reveal tha...

Growth Response and Humoral Immunity of Broiler Chickens Fed Organic Acids Zeolite Coated with Silver Nanoparticles under Heat Stress Conditions

this research was conducted at the department of horticluture, university of tehran during years 2005-2006, to investigate the use of iran apatite rocks in zeoponic substrate and as well to evaluate them as substitutes for phosphate fertilizers. five different substrates namely: m1: 89 wt. % soil+10 wt. % zeolite + 1 wt.% jeyrood apatite; m2: 82 wt.% soil + 15 wt.% zeolite+ 3 wt. % jeyrood apat...

in order to evaluate the effect of zeolite application and selenium spraying on some physiological traits and grain yield in medicinal pumpkin (cucurbita pepo l.) under different moisture regimes, a study was conducted in a factorial experiment based on randomized complete block design with three replications during 2010 in takestan at gazvin province, iran. the three levels of irrigation facto...

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...
