extraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds
سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
Nonmetal ordering in TiC1−xNx: Ground-state structure and the effects of finite temperature
The TiC1−xNx system has long been prized in industry because of its desirable thermodynamic and hardness characteristics. Previous studies have not produced comprehensive results describing the ordering tendencies of TiC1−xNx at any temperature. We apply the mixed-basis cluster expansion and Monte Carlo methods to the problem and find a fascinating array of ground-state structures occurring at ...

متن کاملGroup 12 metal zwitterionic thiolate compounds: preparation and structural characterization.
Reactions of TabHPF(6) (Tab = 4-(trimethylammonio)benzenethiolate) with three equiv. of M(OAc)(2)·2H(2)O (M = Zn, Cd) gave rise to two tetranuclear adamantane-like compounds, [M(4)(μ-Tab)(6)(Tab)(4)](PF(6))(8)·S (·S: M = Zn, S = DMF·4H(2)O; ·S: M = Cd, S = DMF·5H(2)O). The similar reactions of MCl(2) (M = Zn, Cd, Hg) with four equiv. of TabHPF(6) in the presence of Et(3)N afforded three mononuc...
متن کاملOrbital Ordering in Transition-metal Compounds: I. the 120-degree Model
We study the classical version of the 120-model. This is an attractive nearest-neighbor system in three dimensions with XY (rotor) spins and interaction such that only a particular projection of the spins gets coupled in each coordinate direction. Although the Hamiltonian has only discrete symmetries, it turns out that every constant field is a ground state. Employing a combination of spin-wave...
