[ 1 ] - تولید پوشش متخلخل از الیاف پلی وینیل پیرولیدون به روش الکتروریسی با اثر القای فارادی
الکتروریسی روش سریع، ساده و کارآمد در تولید الیاف به شمار می‌رود. در این مقاله، نتایج حاصل از الکتروریسی فیبرهایی از پلیمر نارسانای پلی وینیل پیرولیدون حلال اتانول در حضور میدان مغناطیسی متغیر ارائه می‌گردد. بررسی نمونه ها با میکروسکوپ نوری نشان داد اعمال میدان مغناطیسی متغیر در حین ساخت فیبر موجب پیچیده شدن آنها می شود در حالی که در غیاب میدان الیاف با ساختاری تصادفی و غیر مارپیچ شکل می‌گیرند....
[ 2 ] - تغییر ترشوندگی لایه اکسید گرافین با استفاده از کاهش به روش فوتوکاتالیستی
In this paper, the effect of photocatalytic reduction on hydrophilicity of graphene oxide nanosheets is presented. The graphene oxide nanosheets were prepared by oxidation and exfoliation of natural graphite. The prepared samples were exposed to UV irradiation in presence of TiO2 nanoparticles. Raman spectroscopy and atomic force microscopy show that roughness of the surface is increased due to...
[ 3 ] - ویژگی‌های اپتیکی و ساختاری نانوذرات دی‌اکسید تیتانیوم تثبیت شده بر روی اکسید گرافین در اثر عملیات حرارتی
In this paper, we study the decorated graphene oxide with titanium dioxide nanoparticles. In order to produce this nanomaterial, the titanium dioxide nanoparticles were produced and anchored simultaneously on graphene oxide sheets by arc current. The morphology of the prepared samples was studied by scanning and tunneling electron microscopy, showing that nanoparticles were stabilized on the gr...
[ 4 ] - Preparation and Characterization of Cerium Doped Titanium Dioxide Nanoparticles by the Electrical Discharge Method
Titanium dioxide nanoparticles (TiO2) are known as a widely used photocatalyst. In order to improve the performance of these nanoparticles, the recombination of the electron-cavity pair must be reduced and the absorption rate of the visible region should be expanded. One way to increase the performance of these nanoparticles is using cerium doped TiO2. In the present study, pure and doped titan...
[ 5 ] - Carbon black-intercalated reduced graphene oxide electrode with graphene oxide separator for high-performance supercapacitor
We present a general study on a high performance supercapacitor based on intercalated reduced graphene oxide with carbon black nanoparticles. Graphene oxide sheets were synthesized by oxidation and exfoliation of natural graphite and were reduced using hydroiodic acid in the presence of carbon black nanoparticles. Graphene paper was fabricated by one-step procedure via simultaneous reducing and...
