The purpose of this study was to investigate the relationship between the chemical form and localization of zinc (Zn) in plant leaves and their Zn accumulation capacity. An interspecific cross between Arabidopsis halleri sp. halleri and Arabidopsis lyrata sp. petrea segregating for Zn accumulation was used. Zinc (Zn) speciation and Zn distribution in the leaves of the parent plants and of selec...
این پژوهش به منظور بررسی تأثیر محلولپاشی روی، بر و منگنز بر عملکرد گلرنگ رقم محلی اصفهان تحت شرایط مختلف رطوبتی در بهار و تابستان 1394 در منطقه قزوین انجام شد. این آزمایش به صورت کرتهای یکبار خرد شده در قالب طرح بلوکهای کامل تصادفی در 3 تکرار اجرا شد. عوامل مورد آزمایش شامل: دور آبیاری در 3 سطح (I1: آبیاری هر 6 روز یکبار، I2: آبیاری هر 9 روز یکبار و I3: آبیاری هر 12 روز یکبار) به عنوان عامل ...
A new concept in multifunctional anticancer agents is demonstrated. Tetrakis-(diisopropyl-guanidino) zinc phthalocyanine (Zn-DIGP) exhibits excellent properties as a photodynamic therapy (PDT) agent, as well as potential anti-metastatic activities in vivo. Zn-DIGP exhibits good cellular uptake and low toxicity in the dark (EC50 > 80 μM) and is well tolerated upon its intravenous injection into ...
The Dirac spin liquid ground state of the spin 1/2 Heisenberg kagome antiferromagnet has potential instabilities. This has been suggested as the reason why it does not emerge as the ground state in large-scale numerical calculations. However, previous attempts to observe these instabilities have failed. We report on the discovery of a projected BCS state with lower energy than the projected Dir...
Using structure-directing agents, pore space partitions of a Zn-phosphonocarboxylate framework have been achieved. Selective adsorption of CO(2) over N(2) has been greatly improved from ca. 9 : 1 to 94 : 1.
برای بررسی تأثیر سطوح رطوبت خاک، روی (Zn) و فسفر (P) بر ویژگیهای رشد سیبزمینی(Solanum tuberosum L.) رقم آگریا، آزمایشی بهصورت فاکتوریل با طرح پایه بلوکهای کامل تصادفی و با سه فاکتور کود Zn در سه سطح (0، 10 و 20 میلیگرم Zn بر کیلوگرم خاک از منبع سولفات روی)، کود P در سه سطح (0، 30 و 60 میلیگرم P بر کیلوگرم خاک از منبع مونوکلسیم فسفات) و رطوبت خاک در سه سطح (FC9/0 تا FC، FC7/0 تا FC8/0 و FC...
Fixed angle surface plasmon coupled fluorescence (SPCF) from iron thin films is demonstrated for the first time. The optimum thickness of the iron thin films was determined to be 15 nm using Fresnel calculations. The angles of minimum reflectivity for light at 496-814 nm were predicted to occur at a fixed and broad range of angles of 60-70°. Experimental corroboration of these predictions were ...
Confirmation of direct photogeneration of intrinsic delocalized free carriers in small-molecule organic semiconductors has been a long-sought but unsolved issue, which is of fundamental significance to its application in photo-electric devices. Although the excitonic description of photoexcitation in these materials has been widely accepted, this concept is challenged by recently reported pheno...
