بر اساس تقریب چگالی وزنی wda فرمولبندی دیگری برای مایعات کلاسیک غیریکنواخت به دست آمده است که تقریب چگالی وزنی اصلاح شده nwda نامیده می شود. در این روش همه مرتبه های بسط تابعی انرژی اضافی با استفاده از روش خودسازگاری به کار می رود. تابع همبسته مستقیم دوتایی مایع کره های سخت به کار رفته در این روش معمولا py (percus-yevick) می باشد و ما در این مقاله برای اولین بار از توابع همبسته مستقیم دوتایی پی...
The use of insects as feedstock for biodiesel production has sparsely been studied and very little is known the fuel properties engine performance insect biodiesel. In this study, was initially produced from an M. nigeriensis, then its physicochemical were characterized. via three-step process lipid extraction, acid esterification (1 wt% H2SO4) alkaline transesterification (0.5 NaOH). optimal r...
Magnetization dynamics and field dependent magnetization of different devices based on 25-30 nm thick Permalloy (Py) films: such as single Py layers (Py/MgO; Py/CoFeB/Al2O3) and Py inserted as a magnetic layer in magnetic tunnel junctions (Py/CoFe/Al2O3/CoFe; Py/CoFeB/Al2O3/CoFe; Py/MgO/Fe) have been extensively studied within a temperature range between 300 K down to 5 K. The dynamic response ...
The purpose of this study was to expand our knowledge of small RNAs, which are known to function within protein complexes to modulate the transcriptional output of the cell. Here we describe two previously unrecognized, small RNAs, termed pY RNA1-s1 and pY RNA1-s2 (processed Y RNA1-stem -1 and -2), thereby expanding the list of known small RNAs. pY RNA1-s1 and pY RNA1-s2 were discovered by RNA ...
The in situ reaction of the tripodal anion [EtAl((Me)Py)3](-) ((Me)Py = 6-Me-2-py) with SnCl2 gives the Janus-head ligand ((Me)Py)3Sn-Sn((Me)Py)3, containing a Sn-Sn bond, through a novel, one-pot reaction involving a combination of pyridyl transfer and metal-oxidation.
[IrCl(COE)2]2 (1) reacts with pyridine (py) and H2 to form crystallographically characterized IrCl(H)2(COE)(py)2 (2). 2 undergoes py loss to form 16-electron IrCl(H)2(COE)(py) (3), with equivalent hydride ligands. When this reaction is studied with parahydrogen, 1 efficiently achieves hyperpolarization of free py (and nicotinamide, nicotine, 5-aminopyrimidine, and 3,5-lutudine) via signal ampli...
The reaction of the Tc(II) nitrosyl complex (Bu(4)N)[Tc(NO)Cl(4)] with Di-(2-picolyl)(NEt)amine in methanol yields the neutral complex [Tc(NO)Cl(py-N(Et)-py)]. The reaction of the Tc(I) nitrosyl complex [Tc(NO)Cl(2)(HOMe)(PPh(3))(2)] with this tridentate ligand yields cationic [Tc(NO)Cl(py-N(Et)-py)(PPh(3))]Cl. These two complexes have been structurally characterized. The reaction of [Tc(NO)Cl(...
