Green tea leaves have high contents of phenolic compounds which has strong antioxidant properties but can have bitter taste which makes it less useful in food applications. Encapsulation in nanoliposomes could mask undesirable taste of green teas components and protect them against processing and storage. The objective of this study was to: 1) produce and evaluate physical properties of green t...
Abstract: Spectrophotometric studies were successfully used in quantitative analysis of Amitriptyline Hydrochloride (ATH) Two new methods using spectrophotometry are described for the determination of (ATH) with potassium bromate as the oxidizing agent and acid dyes, Methyl orange and Indigo carmine. Both spectrophotometric methods are based o...
ددر این تحقیق استفاده از کربن اکتیو ، ذرات نانو مغناطیسی آهن و ذرات نانو کامپوزیت آهن- کربن اکتیو، برای حذف رنگ آنیونی از پسابهای سمی مورد مطالعه قرار گرفتند . رنگ direct orange -26 به عنوان مدلی از رنگ آنیونی مورد بررسی قرار گرفت. مشخصات سطحی نانو ذرات آهن و نانو کامپوزیت آهن توسط sem مورد بررسی قرار گرفت . تاثیر عوامل مختلف (ph ، دوز جاذب، زمان تماس، دور هم زدن) به روش طراحی آزمایش تاگوچی مور...
چکیده: شته ی رز macrosiphum rosae (l.) (homoptera: aphididae)، یکی از مهمترین آفات گل های رز (rosa spp.) بوده که با تغذیه از شیره ی گیاهی جوانه ها و سرشاخه ها، مانع باز شدن برگ ها و غنچه ها شده و موجب تضعیف گیاه می شود. آگاهی از ویژگی های زیستی این آفت روی ارقام مختلف گل رز، می تواند در معرفی ارقام نسبتاً حساس یا غیر حساس نسبت به آلودگی های این آفت مفید باشد. پارامترهای دموگرافی این شته در شرایط...
In order to improve the dispersion of nano-TiO₂ particles and enhance its self-cleaning properties, including photocatalytic degradation of pollutants and surface hydrophilicity, we prepared nano-TiO₂-coated SiO₂ microsphere composite self-cleaning materials (SiO₂-TiO₂) by co-grinding SiO₂ microspheres and TiO₂ soliquid and calcining the ground product. The structure, morphology, and self-clean...
In this study, CN-TiO₂ was modified with cryptomelane octahedral molecular sieves (OMS-2) by the sol-gel method based on the self-assembly technique to enhance its photocatalytic activity under the daylight irradiation. The synthesized samples were characterized by X-ray diffraction (XRD), UV-vis spectroscopy, Fourier transform infrared spectroscopy (FT-IR) and porosimeter analysis. The results...
Zirconium based metal organic frameworks (Zr-MOFs) have become popular in engineering studies due to their high mechanical stability, thermostability and chemical stability. In our work, by using a theoretical kinetic adsorption isotherm, we can exert MOFs to an acid dye adsorption process, experimentally exploring the adsorption of MOFs, their external behavior and internal mechanism. The resu...
This study was conducted to investigate the use of cubic LaMnO3 nano-perovskite as a green catalyst for the degradation of an aqueous solution of methyl orange under different conditions. Nanoscale cubic lanthanum manganite with the particle size of ~20 nm was successfully synthesized via citrate sol-gel method. The sample was characterized using the FT-IR and UV-Vis spectroscopy, XRD, SEM, and...
