High-valent metal-oxo intermediates in energy demanding processes: from dioxygen reduction to water splitting.
Four-electron reduction of dioxygen to water and splitting of water to dioxygen are extremely important processes in the context of attaining clean renewable energy sources. High-valent metal-oxo cores are proposed as reactive intermediates in these vital processes, although they have only been isolated in extremely rare cases in the biological systems thereby making the mechanism ambiguous. Re...
متن کاملthe role of russia in transmission of energy from central asia and caucuses to european union
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 اولMemory-Demanding Password Scrambling
Most of the common password scramblers hinder passwordguessing attacks by “key stretching”, e.g., by iterating a cryptographic hash function many times. With the increasing availability of cheap and massively parallel off-the-shelf hardware, iterating a hash function becomes less and less useful. To defend against attacks based on such hardware, one can exploit their limitations regarding to th...

متن کاملReflection high-energy electron diffraction from carbon nanotubes
Using reflection high-energy electron diffraction, we have observed diffraction patterns from both vertically aligned and randomly oriented multiwalled carbon nanotube samples. The patterns, for both samples, consist of rings and are similar to the patterns observed in x-ray diffraction from multiwalled carbon nanotubes. The ring radii are roughly consistent with powder diffraction from graphit...
