سنتز نانو ساختارهای پلاتین-قلع با استفاده از کمپلکس آلی – فلزی پلاتین و قلع در مرز مشترک تولوئن - آب
آلیاژ شدن فلزات غیر نجیب با پلاتین یک روش محبوب برای تولید کاتالیزورهای پلاتینی است که همراه با کاهش مصرف و افزایش فعالیت پلاتین است. این پژوهش، یک روش ساده و موثر جهت تهیه ی لایه ی نازک نانوذرات pt/sn، pt3/sn/go و pd/sn بر اساس کاهش کمپلکس ptcl2(cod)]]، pdcl2(cod)]] و ترکیب snme4 در سطح مشترک تولوئن-آب و در غیاب پایدار کننده ارائه می دهد. استفاده از پیش ماده ی آلی-فلزی که قادر به تخریب به صورت...
Epoxy is a versatile resin used in different fields such as coatings, colors, colorants, and composites. Adding nano-scale fillers/additives to the epoxy has valued epoxy coatings for engineering applications, and opened the time of advanced epoxy-based nanocomposite coatings. In the present work, graphene oxide GO was chemically functionalized with starch, as a natural polymer, and added to th...

Graphene oxide (GO) thin films were simply deposited on fluorine doped tin oxide (FTO) substrate via a low-voltage electrodeposition. The GO and GO thin films were characterized by Zeta Potential, X-ray diffraction, Ultraviolet-Visible spectroscopy, atomic force microscopy, Fourier transform infrared spectroscopy, field emission scanning electron microscopy and energy dispersive X-ray spectrosc...
objective (s): there is corroborating evidence to substantiate redox imbalance and oxidative stress in sepsis that finally leads to organ damage or even death. gamma oryzanol (go) is one of the major bioactive components in rice bran has been considered to function as an antioxidant. the present study was carried out to evaluate the antioxidant activity of gamma oryzanol in vitro and its effica...
Introduction: In motivation and learning areas, achievement goals are of special importance whose behavioral outcome is academic achievement. Goal Orientation (GO) is based on the premise that human behavior is purposeful and people are driven by goals. Therefore, it has motivational implications for learning and performance. The purpose of this paper was to examine the relationship between GO ...
