Crystallization induced chiral locking of a central labile core in a star-shaped tetra-nuclear complex.
The central labile Al(III) core of a star-shaped tetra-nuclear metal complex, [{Delta-Ru(III)(acac)(2)(taet)}(3)Al(III)] (acac = acetylacetonato; taet = tetraacetylethanato), which was synthesized by reacting Delta-[Ru(III)(acac)(2)(taetH)] (taetH = singly protonated taet) with an Al(III) ion in solution, was found to be locked as a Lambda-form in the solid state.
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولChirality effects on core-periphery connection in a star-burst type tetranuclear Ru(III) complex: application of vibrational circular dichroism spectroscopy.
Vibrational circular dichroism (VCD) spectroscopy was applied to study the stereochemical properties of a star-burst type tetranuclear Ru(III) complex, Δ-(or Λ-)[{Δ-(or Λ-)-Ru(III)(acac)(2)(taet)}(3)Ru(III)] (acac = acetylacetonato; taet = tetraacetylethanato). By comparing the VCD spectra of eight diastereomeric enantiomers, it was shown that the spectra reflected the homo- or hetero-chiral na...

کارشناسان "بررسی مقابله ای نوشتار" در زبان های مختلف بر این باورند که زبان و فرهنگ مبدأ بر نحوه ی نگارش نویسندگان در زبان دوم تاثیر گذار است. درخواست نامه های شغلی نیز از این قاعده مستثنا نیستند. بر پایه ی اصول بررسی "ژانر" یا "نوع" قادر خواهیم بود به بینشی در زمینه ی یک "ژانر" یا "نوع" خاص مانند درخواست نامه های شغلی دست یابیم. علیرغم مطالعات متعدد در زمینه ی جنبه های گوناگون "بررسی نوع" و ...
15 صفحه اولa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
