در این مطالعه غلظت عناصر محلول در خاک و گیاه اطراف کارخانه ذوب مس خاتون آباد (Al, As, Ba, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Rb, S, Si, Sr, Zn) و تجمع و انتقال این عناصر در گیاه Astragalus sp. با فاکتور انتقال مورد بررسی قرار گرفت. جهت تعیین تغییرات انها از ازمون ANOVA و دانکن استفاده شد. همبستگی عناصر با یکدیگر توسط ضریب همبستگی پیرسون مورد بررسی قرار گرفت. نتایج نشان داد، بیشترین غلظت عناصر مربو...
A series of π-bound Mo-quinonoid complexes supported by pendant phosphines have been synthesized. Structural characterization revealed strong metal-arene interactions between Mo and the π system of the quinonoid fragment. The Mo-catechol complex (2a) was found to react within minutes with 0.5 equiv of O(2) to yield a Mo-quinone complex (3), H(2)O, and CO. Si- and B-protected Mo-catecholate comp...
Herein, the organic semiconductor methyl orange (MO), is investigated for the first time for its electronic applications. For this purpose, Al/MO/n-Si heterojunction is fabricated through economical cheap and simple “drop casting” technique. The currentvoltage (I-V) measurements of the device are made at room temperature under dark conditions. The I-V characteristics of Al/MO/n-Si junction exhi...
