[ 1 ] - Chemical Composition of the Volatile Fraction of Perovskia abrotanoides and Nepeta glomerulosa. Growing Wild in Iran by Different Extraction Methods

Background & Aim: Essential oils are isolated from different sections of plants such as flowers, seeds, leaves, stems and roots. Essential oils are applied extensively in producing of perfumes, cosmetics, foods, beverages and confectioneries and as ingredients of disinfectants and insecticides. Experimental: Essential oil are obtained by several isolation methods, such as hydrodistillation (HD...

[ 2 ] - مطالعه مقایسه ای روی سرعت تخریب فوتوکاتالیستی تتراسایکلین با استفاده از نانو ذرات ZnS و Cu-loaded ZnSحساس شده به نور مرئی

نانو ذراتZnS و Cu-loaded ZnS حساس شده به نور مرئی با استفاده از روش ترسیب شیمیایی سنتز شد که در این سنتز از رنگ طبیعی آنتوسیانین به عنوان حساس کننده و بازدارنده رشد استفاده شد. از تکنیکهای XRD و TEM و UV-Vis جهت شناسایی و بررسی ویژگی های ساختاری نانو ذرات استفاده شد. سپس اثر فوتوکاتالیستی این نانو ذرات در تخریب تتراسایکلین مورد مقایسه و سنجش قرار گرفت و میزان تخریب فوتوکاتالیستی تتراسایکلین توس...

[ 3 ] - Synthesis of ZnO-nanoparticles by microwave assisted sol-gel method and its role in photocatalytic degradation of food dye Tartrazine (Acid Yellow 23)

ZnO- nanoparticles with an average particle size of 24 nm were successfully synthesized using the microwave assisted sol- gel technique. Structural and morphological properties of the nanoparticles were characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), Energy disperse spectrum (EDS) and Fourier transform infrared spectroscopy (FTIR). The band gap ene...
