[ 1 ] - تهیه پوششهای دی اکسید تیتانیم آلاییدهشده با آهن به روش پوششدهی چرخشی پیشماده پلیمری و بررسی فعالیت فوتوکاتالیزوری آنها تحت تابش نور مرئی
دی اکسید تیتانیم نانومتری به دلیل کاربردهای فراوان در نیمه هادیها، حسگرها، مواد آنتیباکتریال و بهداشتی، فتوکاتالیزورها و سلولهای خورشیدی مورد توجه زیادی قرار گرفته است. در این تحقیق، پوششهای نانوساختاری دی اکسید تیتانیم خالص و آلاییده شده با آهن به روش پوششدهی چرخشی پیشماده پلیمری تهیه شدند. نمونههای تهیه شده توسط روشهای پراش پرتو ایکس، طیفسنجی FT-IR، طیفسنجی UV-Vis و میکروسکوپ نیروی...
[ 2 ] - Cyclic Voltammetry Investigation of the Mechanism of CuInSe2 and CuIn(Al)Se2 Electrodeposition from Aqueous Solution
Electrodeposition of CuInSe2 (CIS) and CuInAlSe2 (CIAS) from aqueous solution has been systematically investigated by cyclic voltammetery implementing different scan rates. It has been shown that electrodeposited CIS and CIAS have been formed on the substrate through electrochemical-chemical interaction of reduces species on the substrate. From the obtained results, it could be inferred that I...
[ 3 ] - Optimizing of Iron Bioleaching from a Contaminated Kaolin Clay by the Use of Artificial Neural Network
In this research, the amount of Iron removal by bioleaching of a kaolin sample with high iron impurity with Aspergillus niger was optimized. In order to study the effect of initial pH, sucrose and spore concentration on iron, oxalic acid and citric acid concentration, more than twenty experiments were performed. The resulted data were utilized to train, validate and test the two layer artificia...
[ 4 ] - Modeling of Compressive Strength of Metakaolin Based Geopolymers by The Use of Artificial Neural Network RESEARCH NOTE)
In order to study the effect of R2O/Al2O3 (where R=Na or K), SiO2/Al2O3, Na2O/K2O and H2O/R2O molar ratios on the compressive strength (CS) of Metakaolin base geopolymers, more than forty data were gathered from literature. To increase the number of data, some experiments were also designed. The resulted data were utilized to train and test the three layer artificial neural network (ANN). Bayes...
