One of the problems in removing pollutants from water  by photocatalytic methods is the separation of the catalyst from the solution. In this study, the catalyst stabilization method was used to solve this problem. Nano ZnFe2O4 supported on Copper Slag (CS) produced in this research is an environment-friendly, simple and cost-effective catalyst. ZnFe2O4</su...

Alumina-supported Cs3[Re(C2O4)3] precursor has been synthesized  for preparation of Re-Cs/g-Al2O3 catalyst. Cs3[Re(C2O4)3]  has been prepared from the reaction of ReCl3 with  H2C2O4.2H2O and CsCl in ...

Two new heterogenized epoxidation nanocatalysts based on molybdenum and tungsten compounds were prepared withcovalent grafting of MCM-41 with 3-aminoropropyl trimethoxysilane and subsequent reaction with diphenylphosphinobenzaldehyde and complexation with M (Mo, W)O2(acac)2. X-ray diffraction and nitrogen sorption analyses revealed the preservation of the textural properti...

Different methods have been designed to calculate the air quality index in form of mathematical formula. But the formula designed by Central Pollution Control Board in 2014 is more robust to find out the air quality category. The index has been calculated based upon four parameters like particulate matters (PM10, PM2.5), sulfur oxide and nitrogen oxide. The study area has affected by different ...

This study examined emergent coordination processes in collective patterns of behavior in 3 vs 3 sub-phases of the team sport of association football near the scoring zone. We identified coordination tendencies for the centroid (i.e., team center) and surface area (i.e., occupied space) of each sub-group of performers (n=20 plays). We also compared these kinematic variables at three key moments...

In this research new catalyst prepared by supporting ZnFe2O4 on Copper Slag (CS) and characterization of this catalyst was done by using Scanning Electron Microscopy (SEM) image, Energy-Dispersive X-ray (EDX) spectroscopy, BET surface area, and X-Ray Diffraction (XRD) patterns. UV + H2O2 processes by ZnFe2O4...

Tomato  (L.ycopersicon esculentum  Mill.) cv. Rio Grande  seedlings were nutritionally conditioned with solutions complete fertilizer N(60% NO3+40% NH4)-P-K (20-20-20) , N(30%NO3+70% NH4)-P-K (15-5-30) , the first two week   N(60% NO3+40% NH4)-P-K (20-20-20) and later two week  N(30%NO3+70% NH4)-P-K...
