[ 1 ] - Catalytic production of biodiesel from corn oil by metal-mixed oxides

The present study investigates the transesterification of corn oil with methanol over two oxides of MgO and ZnO at 65 ͦC and 1 atm. These two catalysts have been prepared via a conventional co-precipitation process. As for MgO, the corresponding mixed metal nitrate solution has been mixed and heated at the presence of urea. ZnO has also been synthesized by co-precipitation of metal acetate at th...

[ 3 ] - اکسید گرافن کربوکسیله به‌عنوان لایۀ تزریق‌کنندۀ حفرۀ مؤثر در دیود نورگسیل پلیمری

In this work, polymer light-emitting diode (PLED) with configuration of glass/ITO/GO-COOH/MEH-PPV/Al was fabricated. At first, indium tin oxide (ITO) thin ﬁlm was deposited on glass substrates by radio frequency (RF) sputtering and the influence of synthetic carboxylated graphene oxide (GO-COOH) as the hole-injection layer (HIL) on the performance of the PLED made from poly [2-methoxy-5- (2&rsq...

[ 4 ] - مقایسه مدل‌های HK، اDA و DS در تعیین توزیع اندازه حفرات جاذب‌های کربنی ریز حفره با استفاده از جذب دی اکسید کربن

در این مقاله، ایزوترم جذب دی اکسید کربن در دمای K 273 بر روی پنج جاذب کربنی تجاری، به روش حجمی اندازه‌گیری شده است. در ادامه به کمک داده‌های تعادلی جذب، توزیع اندازه حفرات این جاذب‌ها، با سه مدل DS، DA و HK تعیین و مقایسه شده است. نتایج نشان می‌دهد، هر چند متوسط قطر حفرات به‌دست آمده از این مدل‌ها، تقریباً یکسان است ولی این مدل‌ها توزیع اندازه حفرات متفاوتی را ارائه می‌کنند. در ادامه نتایج حاصل ...
