[ 1 ] - Enhancing Photocatalytic Activity of Nitrogen Doped TiO2 for Degradation of 4-Chlorophenol under Solar Light Irradiation
The nitrogen doped TiO2 as heterogeneous photocatalyst via sol-gel method were successfully synthesized. The physicochemical, morphological and textural characteristics of the obtained TiO2 samples were characterized by advanced analysis techniques. The photocatalytic activity of the samples were evaluated for degradation of 4-CP under solar irradiation. The as-synthesized photocatalysts were c...
[ 2 ] - Pressure Profile Estimation through CFD in UBD Operation Considering with Influx to Wellbore
Nowadays, UnderBalanced Drilling (UBD) technology is widely applicable in the petroleum industry due to its advantages to an overbalanced drilling operation. UBD success depends on maintaining the drilling fluid circulating pressure below the reservoir pore pressure during operations. One of the main prerequisites of a successful UBD operation is the correct estimation of the pressure profi...
[ 3 ] - اثرات ویسکوالاستیسیته و پتانسیل جریانی بر واکنشهای سطح در میکرورآکتورها
بسیاری از سیالات زیستی مورد بررسی در آزمایشگاه‌های-روی-تراشه (آزروشه) رفتاری غیرخطی دارند. همچنین به علت اندازه بسیار کوچک مجاری موجود در اجزای مختلف آزروشه ها، همانند میکرورآکتورها و میکروهم زن ها، جریان فشار-محرک مایعات در این اجزا با پدیده پتانسیل جریانی همراه خواهد بود که تمایل به کاهش سرعت سیال دارد. تحقیق حاضر به بررسی اثرات پتانسیل جریانی و رفتار غیرنیوتنی سیال حامل بر انتقال جرم و واکنش...
