چکیده
in this research, a single-stage low-temperature hydrothermal synthesis route was successfully developed for preparation of iron disulfide. the prepared powder was characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem). these analyses showed that nanoparticles were well crystallized, pyrite was the main product and the shape of crystals was nanorod. also, the influences of reaction temperature and iron source on the formation of the target compound were investigated.

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولProduction of Hydroxylapatite from Biowaste, Chicken Manure by Hydrothermal Process
Hydrothermal process has been applied for effective production of Hydrogen from biowastes. In this study hydrothermal process for production of valuable Hydroxylapatitefrom chicken manure containing phosphorus was focused on. Conditions of 400 ̊C and 26 27 MPa with addition of 1 mmol Ca(OH)2 were determined as the optimal by using Ophospho-DL-serine as a model compound. Afterwards, the real biow...
متن کاملTuning photoluminescence of organic rubrene nanoparticles through a hydrothermal process
Light-emitting 5,6,11,12-tetraphenylnaphthacene (rubrene) nanoparticles (NPs) prepared by a reprecipitation method were treated hydrothermally. The diameters of hydrothermally treated rubrene NPs were changed from 100 nm to 2 μm, depending on hydrothermal temperature. Photoluminescence (PL) characteristics of rubrene NPs varied with hydrothermal temperatures. Luminescence of pristine rubrene NP...
متن کاملSurfactant-assisted synthesis of Barium hexaferrite nanoparticles by hydrothermal method
In the present work, the synthesis of Barium hexaferrite (BaFe12O19) nanoparticles in thepresence of a large excess amount of OH− anions by the hydrothermal method in the presence and absence of surfactants such as Sodium dodecyl benzene sulfonate and Triton X-114 was reported. The optimized temperature in the absence of surfactant was determined (200 °C) and then Barium hexaferrite nanoparticl...
متن کاملSynthesis and morphology characterization of SnO2 nanoparticles by hydrothermal method
Nanoparticles are widely used in different applications such as cancer cell treatment and antibacterial agents. SnO2 nanoparticles were synthesized successfully by hydrothermal method and subsequent calcination using Tin (II) chloride- dihydrate, Sodium hydroxide, in presence of Hexadecyltrimethylammoniumn bromide (CTAB) as Surfactant. These nanoparticles were characterized by using Fourier tra...
