Switchable ErSc2N rotor within a C80 fullerene cage: an electron paramagnetic resonance and photoluminescence excitation study.
Motivated by the possibility of observing photoluminescence and electron paramagnetic resonance from the same species located within a fullerene molecule, we initiated an EPR study of Er3+ in ErSc2N@C80. Two orientations of the ErSc2N rotor within the C80 fullerene are observed in EPR, consistent with earlier studies using photoluminescence excitation (PLE) spectroscopy. For some crystal field ...
متن کاملScandium carbide/cyanide alloyed cluster inside fullerene cage: synthesis and structural studies of Sc3(μ3-C2)(μ3-CN)@Ih-C80.
A new Sc3(C2)(CN)@Ih-C80 metallofullerene encaging a scandium carbide/cyanide alloyed cluster was prepared and investigated. Sc3(C2)(CN)@Ih-C80 was synthesized by the arc-discharging method and isolated by HPLC. Its experimental (13)C NMR spectrum with two signals clearly confirms an icosahedral C80 cage, and theoretically calculated (13)C NMR peaks agree well with the experimental results. Fur...
متن کاملMetal-Polyhydride Molecules Are Compact Inside a Fullerene Cage.
Quantum chemical calculations show that metal-hydride molecules are more compact when they are placed inside a fullerene cage than when they are isolated molecules. The metal-hydrogen bond distance in ZrH4 becomes 0.15 Å shorter when it is placed inside a C60 cage. Metal-polyhydride molecules with a large number of H atoms such as ScH15 and ZrH16, which are not bound as isolated molecules, are ...
متن کاملNon-covalent single transcription factor encapsulation inside a DNA cage.
Regulation of gene expression is fundamental for cell development, maintenance, and growth. Gene regulation occurs mainly at the level of transcription, controlled primarily by DNA-binding proteins known as transcription factors (TFs). For example, the delivery of just four TFs to fully differentiated cells can cause them to revert to a stemcell-like state, offering promise for regenerative med...

در این رساله t_n - علیت قوی تعریف می شود. این رده ها در جدول علیت فضا- زمان بین علیت پایدار و علیت قوی قرار دارند. یک قضیه برای رده بندی آنها ثابت می شود و t_n- علیت قوی با رده های علی کارتر مقایسه می شود. همچنین ثابت می شود که علیت فشرده پایدار از t_n - علیت قوی نتیجه می شود. بعلاوه به بررسی رابطه نظریه دامنه ها با نسبیت عام می پردازیم و ثابت می کنیم که نوع خاصی از فضا- زمان های علی پایدار, ب...
