[ 1 ] - Green synthesis of magnetic copper ferrite nanoparticles using tragacanth gum as a biotemplate and their catalytic activity for the oxidation of alcohols
During this study, we report the green synthesis of magnetic copper ferrite nanoparticles using tragacanth gum as a reducing and stabilizing agent by the sol-gel method. The green synthesized CuFe2O4 MNPs are characterized by powder X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), vibrating sample magnetometer (VSM) and scanning electron microscopy...
[ 2 ] - Synthesis of electron-poor N-Vinylimidazole derivatives catalyzed by Silica nanoparticles under solvent-free conditions
Protonation of the highly reactive 1:1 intermediates, produced in the reaction between triphenylphosphine and acetylenic esters, by NH-acids such as azathioprine, imidazole or theophylline leads to the formation of vinyltriphenylphosphonium salts, which undergo a Michael addition reaction with a conjugate base to produce phosphorus ylides. Silica nanoparticles (silica NPs were prepared by therm...

[ 8 ] - اثر بیوچار پوست بادام‌زمینی اصلاح شده با پرمنگنات پتاسیم بر حذف کادمیوم از محیط آبی
کادمیوم فلزی تخریبناپذیر و یکی از سمی‌ترین فلزات سنگین است که می‌تواند وارد اکوسیستم‌های آبزی شده، در زنجیره غذایی تجمع یابد و تهدیدی جدی برای موجودات آبزی و سلامت انسان باشد. در این پژوهش تأثیر پوست بادام‌زمینی (PN)، بیوچار اولیه (PBc) و بیوچار مهندسی‌شده با پرمنگنات پتاسیم (PPBc) در حذف کادمیوم از محیط‌های آبی مورد بررسی قرار گرفت. برخی ویژگی‌های جاذب‌ها نظیر pH، ظرفیت تبادل کاتیونی، گروه‌ها...
[ 9 ] - One-pot three-component synthesis of tetrahydrobenzo[b]pyrans in the presence of Ni0.5Cu0.5Fe2O4 magnetic nanoparticles under microwave irradiation in solvent-free conditions
Ni0.5Cu0.5Fe2O4 magnetic nanoparticles using Arabic gel (AG) as a reducing and stabilizing agent was prepared by the sol-method. The catalyst identification was performed using Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM). The magnetic anal...
