[ 1 ] - Electrochemical Determination of Mesalazine by Modified Graphite Paste Electrode with Poly (Benzoquinone) Chromium(III) Complex
In this work, for the first time poly (benzoquinone) chromium (III) complex (PBQC) was synthesized with a one pot, one step, simple and fast method. This novel polymer was used for modification of graphite paste electrode for electrochemical determination of Mesalazine. Moreover, this novel modifier was characterized by Fourier transform infrared spectroscopy, Field emission scanning electron m...
[ 2 ] - Simultaneous Voltammetric Measurement of Ascorbic Acid, Epinephrine, Uric Acid and Tyrosine at a Glassy Carbon Electrode Modified with Nanozeolite-Multiwall Carbon Nanotube
In this study, incorporation of iron ion-doped natrolite nanozeolite, multi-wall carbon nanotubes into chitosan-coated glassy carbon electrode for the simultaneous determination of ascorbic acid, epinephrine, uric acid and tyrosine is studied. The results show that the combination of multi-wall carbon nanotubes and iron ion-doped natrolite zeolite causes a dramatic enhancement in the sensitivit...
[ 3 ] - Optimization of the catalytic ozonation process using copper oxide nanoparticles for the removal of benzene from aqueous solutions
The current study aimed to examine the overall feasibility of the use of copper oxide nanoparticles (CuO-NPs) as a catalyst in ozonation process for the removal of benzene from aqueous solutions under experimental conditions. This experimental study was conducted on a laboratory scale reactor in a semi-batch mode. The effect of critical operating parameters such factors as pH, concentration of ...
[ 4 ] - SrFeO3-δ Assisting with Pd Nanoparticles on the Performance of Alcohols Catalytic Oxidation
Current catalysts for the alcohol oxidation in fuel cells (typically noble metals-based) are susceptible to poisoning with intermediates like CO. Hence we decided to find superseded catalysts for methanol oxidation based on incorporation of mixed oxides. In this research, a nano-size perovskite SrFeO3-δ (SrFeO3<su...
[ 5 ] - Fabrication and Characterization of a Conductive Proton Exchange Membrane Based on Sulfonated Polystyrenedivinylbenzene Resin-Polyethylene (SPSDR-PE): Application in Direct Methanol Fuel Cells
A novel proton exchange membrane has been prepared using sulfonated poly(styrene-divinylbenzene) resin(SPSDR)–polyethylene(PE). The membrane is characterized by FT-IR, SEM and TGA/DSC. Water uptake, oxidative resistance, ionic conductivity and methanol permeability are measured to evaluate its performance in a direct methanol fuel cell. The on-set degradation temp...
[ 6 ] - CORROSION INHIBITION OF COPPER IN ACID MEDIUM BY DRUGS: EXPERIMENTAL AND THEORETICAL APPROACHES
The inhibition performances of nafcillin (III), methicillin (II) and penicillin G (I) on the corrosion of copper in HCl was studied and tested by weight loss, Tafel polarization, SEM, UV-vis spectrophotometry, molecular dynamics method and quantum chemical calculations. Polarization curves indicated that the studied inhibitors act as mixed-type inhibitors. The values of inhibition efficiency an...
[ 7 ] - تهیه و شناسایی نانوذرات Cu0.2ZnNi3.27O5.29 به روش هم‌رسوبی و کاربرد آن در پیل‌های سوختی
نانوذرات Cu0.2ZnNi3.27O5.29 با روش هم‌رسوبی سنتز شد. فعالیت نانوکاتالیستی Cu0.2ZnNi3.27O5.29، به تنهایی و با افزودن نانولوله کربنی و با اضافه کردن نانوذرات پالادیم برای اکسایش الکتروشیمیایی متانول با استفاده از الکترود کربن شیشه‌ای با روش ولتاسنجی چرخه‌ای در محیط قلیایی مورد بررسی قرار گرفت و تأثیر برخی عامل‌ها مانند غلظت متانول، غلظت الکترولیت و سرعت روبش مورد مطالعه قرار گرفت. نتایج به‌دست آم...
