Sulfidation Textures of FeNi Alloy in Unequilibrated Chondrites and Its Petrogenesis
A lot of troilite reaction rim textures formed through sulfidation of FeNi alloy of kamacite and taenite with sulfur rich gas have been identified especially in C03 unequilibrated carbonaceous chondrites. Troilite formation through sulfidation of FeNi alloy of kamacite and taenite with sulfur rich gas in the solar nebula is expected from the reaction kinetics as well as from the equilibrium con...

متن کاملOxygen Isotopes of Al-rich Chondrules from Unequilibrated Ordinary Chondrites
Al-rich chondrules (ARCs) are a rare constituent of chondrites. They have relatively high bulk Al20 3 content(> 10 wt%), which is due to the presence of Al-rich phases, such as plagioclase, spinel, Al-rich glass etc. [1]. ARCs share some chemical and petrologic characteristics with Ca, Al-rich inclusions (CAis), and may represent a genetic link between ferromagnesian chondrules and CAis. Twelve...
متن کاملStatic and Dynamic Magnetization of Gradient FeNi Alloy Nanowire
FeNi binary nanowires with gradient composition are fabricated by the electrodeposition method. The energy dispersive spec-trometer line-sweep results show that the composition changes gradually along the wire axis. The gradient FeNi nanowires exhibit polycrystalline and crystal twinning at different areas along the nanowire axis, with a textured face-centered cubic structure. The static and dy...
متن کاملthe survey of the virtual higher education in iran and the ways of its development and improvement
این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
