A three-coordinate Cu-NR(2) system (R = p-tolyl) supported by the anionic bis(phosphino)borate ligand [Ph(2)B(CH(2)P(t)Bu(2))(2)](-) has been isolated and structurally characterized in both its anionic Cu(I) and neutral (formally) Cu(II) oxidation states. A large rate constant for the self-exchange electron-transfer reaction (k(S) >or= 10(7) M(-1) s(-1)) makes this system a functional model for...

We measure directed flow (v_{1}) for charged particles in Au+Au and Cu+Cu collisions at sqrt[s_{NN}]=200 and 62.4 GeV, as a function of pseudorapidity (eta), transverse momentum (p_{t}), and collision centrality, based on data from the STAR experiment. We find that the directed flow depends on the incident energy but, contrary to all available model implementations, not on the size of the colli...

Substitution of Li for Cu in La2Cu12xLixO4 donates holes; at x ­ 0.5 the Li ions form an ordered superlattice which isolates individual CuO4 plaquettes from one another, and the number of doped holes is sufficient that each plaquette is occupied. Above 170 K, an activated temperature dependence of the Cu nuclear spin relaxation rate reveals a magnetic excitation of the doped-hole state with an ...

At low coverage of water on Cu(110), substrate-mediated electrostatics lead to zigzagging chains along [001] as observed with STM [T. Yamada, S. Tamamori, H. Okuyama, and T. Aruga, "Anisotropic water chain growth on Cu(110) observed with scanning tunneling microscopy" Phys. Rev. Lett. 96, 036105 (2006)]. Using x-ray absorption spectroscopy we find an anomalous low-energy resonance at ~533.1 eV ...

در این پژوهش تاثیر عنصر لیتیم بر ریز ساختار و ویژگی های مکانیکی آلیاژ آلومینیوم 380 a بررسی شده است. نشان داده شد هنگامی که لیتیم تا میزان 1/0درصد وزنی به آلیاژ پایه (al-8.5%si-3.5%cu-1%fe) اضافه می شود، ریخت شناسی سیلیسم یوتکتیک و فاز β-al5fesi از حالت صفحات تیغه ای و ضخیم پیوسته به حالت الیافی و ریز بهسازی می شوند. آلیاژ حاوی 06/0 درصد لیتیم استحکام و ازدیاد طول نسبی بالاتری دارد که به احتمال...

Compound [Cu(3)(N(3))(6)(DMF)(2)](n) () was initially obtained in a serendipitous way during efforts to prepare a Cu(II)/N(3)(-)/Mebta coordination polymer (Mebta = 1-methylbenzotriazole). With the identity of established by single-crystal crystallography, a rational preparative route to this complex was designed and carried out by reacting Cu(ClO(4)).6H(2)O with two equivalents of NaN(3) in DM...

The Cu spin-lattice relaxation rate 1/T1 in UCu3.5Pd1.5 has been determined at frequencies 38 MHz<n0 <101 MHz and for temperatures 0.4 K<T<100 K. UCu3.5Pd1.5 was one of the first compounds revealing non-Fermi-liquid behavior which was explained in terms of a distribution of Kondo temperatures TK . In contrast to the broad distribution of single Kondo impurity temperatures TK , which accounted f...

We report collective ferromagnetic behavior with high Curie temperatures (T(c)) in Fe dot assemblies supported by the Cu(111) surface. Our ability to tune the average size and spacing of the individual dots allows us to conclude that enhanced magnetic anisotropy cannot account for this high-T(c) ferromagnetic order. Because our Monte Carlo simulations have ruled out the dipolar interaction as t...

The aim of the study was to investigate distribution, enrichment and accumulation of heavy metals in soil and Trigonella foenum-graecum (var. Pusa Early Bunching) after fertigation with paper mill effluent. Doses of paper mill effluent viz. 5%, 10%, 25%, 50%, 75% and 100% were used for fertigation of T. foenum-graecum along with bore well water (control). The results revealed that paper mill ef...
