[ 1 ] - Inverse Co-precipitation Synthesis of Copper Chromite Nanoparticles
In this study, copper chromite (CuCr2O4) nanoparticles was prepared by inverse co-precipitation method. In this method, cupric nitrate trihydrate, (Cu (NO3)2.3...
[ 2 ] - Simultaneous Determination of Hydrochlorothiazide and Enalapril Maleate in Pharmaceutical Formulations Using Fourier Transform Infrared Spectrometry
A new Fourier Transform-Infra Red (FT-IR) spectrometric method was developed for assaying hydrochlorothiazide (HCT) and enalapril maleate (ENM) in binary solid pharmaceutical formulations. Multivariate Partial Least Squares (PLS) method was used for calibration of derivative spectral data. Acetonitrile was used as solvent due to its spectral tran...
[ 3 ] - Solvothermal synthesis of copper nanoparticles loaded on multi-wall carbon nanotubes as catalyst for thermal decomposition of ammonium perchlorate
Copper nanoparticles were synthesized on multiwall carbon nanotubes, (Cu)/(MWCNTs), based on solvothermal method. The used reagents include MWCNTs, cupric nitrate trihydrate (Cu (NO3)2.3H2O), diethylene glycol (DEG), diethanol amine. Characterization of Cu/MWCNTS nanoparticles was performed by techniques of Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray diffraction sp...
[ 4 ] - مقایسه اثرکاتالیزوری نانوکرومیت مس و نانولولههای کربنی اصلاح شده در تجزیۀ حرارتی آمونیوم پرکلرات
In this study, the effect of copper chromite (CuO.Cr2O3) nanoparticles and multi-walled carbon nanotubes (MWCNTs) as nanocatalysts on the thermal decomposition behavior of ammonium perchlorate (AP) has been investigated using Differential Scanning Calorimetry (DSC). At first, copper chromite (CuO.Cr2O3) nanoparticles were prepared by inverse co-precipitation method. In this method, cupric nitra...
[ 5 ] - بررسی عملکرد آبشیرینکن خورشیدی تک مرحلهای غیرفعال همراه با ماده تغییرفازدهنده
در این پژوهش به بررسی عملکرد آبشیرینکن خورشیدی تک مرحلهای غیرفعال همراه با ماده تغییرفازدهنده پرداخته شده است. ابتدا از بین استئاریکاسید، ستیل الکل و پارافین18-C، یک ماده به عنوان ماده تغییر فاز دهنده مناسب با بیشترین بازده انتخاب گردید. استئاریک اسید به دلیل بالاتر بودن دمای ذوب که منجر به بیشتر شدن انتقال حرارت به خوراک میشود، بازدهی بیشتر را از خود نشان داد و به عنوان ماده تغییرفازدهنده...
