Single walled carbon nanotube in the reaction layer of gas diffusion electrode for oxygen reduction reaction
In this paper, the effect of surface area of reaction layers in gas diffusion electrodes on oxygen reduction reaction was investigated. For this purpose, various amounts (0.1, 0.2, 0.3, 0.4, 0.5, 1, 1.5 and zero %wt of total loading of reaction layer) of single walled carbon nanotube (SWCNT) were inserted in the reaction layer. The performance of gas diffusion electrodes for oxygen reduction re...
متن کاملSpin-Related Micro-Photoluminescence in Fe3+ Doped ZnSe Nanoribbons
Spin-related emission properties have important applications in the future information technology; however, they involve microscopic ferromagnetic coupling, antiferromagnetic or ferrimagnetic coupling between transition metal ions and excitons, or d state coupling with phonons is not well understood in these diluted magnetic semiconductors (DMS). Fe3+ doped ZnSe nanoribbons, as a DMS example, h...
متن کاملElectronic behavior of three oxygen non-stoichiometric Fe4+/Fe3+ oxoperovskites
For comparison with the Mn/Mn oxoperovskites at the crossover from localized to itinerant behavior of the s-bonding e electrons, the electronic properties of three oxygen non-stoichiometric, mixed-valent Fe/Fe oxoperovskites were explored by measuring their resistivity r(T), thermoelectric power a(T), and magnetic susceptibility w(T). Oxidation of Ca2Fe2O5 by annealing in ozone progresses by ox...
متن کاملEffects of in vitro glycation on Fe3+ binding and Fe3+ isoforms of transferrin.
BACKGROUND In diabetes, protein function is altered by glycation, but the impact on the Fe3+ binding and antioxidant functions of transferrin (Tf) is largely unknown. The aim of the present study was to investigate the effects of glycation on the distribution of Fe3+ on the two Fe3+ -binding sites of Tf. METHODS In vitro glycation of Tf was accomplished by preincubation with glucose for 14 da...
متن کاملتجزیه آموکسی سیلین با استفاده از فرآیند الکتروفنتون گرافیت فلت اصلاح‌شده و نانو کاتالیست Fe3 O4
سابقه و هدف: آموکسیسیلین پرمصرفترین آنتیبیوتیکی است که به دلیل ایجاد مقاومت در باکتریها موردتوجه خاصی قرارگرفته است. این ترکیب از مسیرهای مختلفی مانند دفع مستقیم فاضلاب و زائدات پزشکی، دامپزشکی و صنعت می‌تواند، وارد محیطهای آبی شود. هدف از این مطالعه، حذف آموکسی سیلین به‌وسیله فرآیند الکتروفنتون با استفاده از گرافیت فلت اصلاح‌شده و نانو ذرات Fe3O4 از محلول‌های آبی بود. مواد و روشها: ن...
