چکیده
Inspired by the working principle of naturally-existing photosynthetic and respiratory electron transport chains (ETCs) in phototrophic organisms living cells, we have constructed artificial ETCs to promote kinetics transfer thus achieving efficient conversion haze pollutants electricity light- or (photo-thermal) heat-driven liquid flow fuel cells (LFFCs). Ferricyanide (K3[Fe(CN)6]) VO2+/VO2+ with activation HNO3 been screened as anode cathode mediators electrons oxygen. Light-driven LFFC a [email protected]2 photo-anode achieved maximal power density (Pmax) 1.2 mW/cm2 at room temperature, while made Pmax 142.7 90 °C. About 80% overall efficiency haze-to-electricity was obtained. Various wastes including different sugars, lignin, cellulose, urea even coal-burning plant ashes could be converted electricity, indicating promising prospect this technology for application treatment organic coupled generation electricity.

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولOptimizing naturally driven air flow in a vertical pipe by changing the intensity and location of the wall heat flux
Heat transfer from the internal surfaces of a vertical pipe to the adjacent air gives rise to the air flow establishment within the pipe. With the aim of optimizing the convective air flow rate in a vertical pipe, the details of the flow and thermal fields were investigated in the present study. Conservation equations of mass, momentum, and energy were solved numerically using simple implicit f...
