Concomitant formation of differently coordinated copper(II) complexes in the same reaction: Structural studies of [trans-Cu(γ-picoline) 2(H 2O) 4](p-toluene sulfonate) 2·2H 2O and [trans-Cu(γ-picoline) 4](p-toluenesulfonate) 2·2H 2O
No full textTwo new copper(II) complexes comprising of coordinated and non-coordinated p-toluenesulfonate, [trans-Cu(γ-pic) 2(H 2O) 4](pts) 2·2H 2O, 1 and [trans-Cu(γ-pic) 4(pts) 2]·2H 2O, 2 (where p-toluenesulfonate = pts and γ-picoline = γ-pic) have been isolated from the same reaction mixture. These complexes have been characterized by spectroscopic techniques, molar conductance, TGA, magnetic susceptibility studies, and single crystal X-ray structure determination. Both complexes crystallize in the monoclinic crystal system with P2 1/c space group having cell dimensions of a = 8.0203(2) , b = 19.4471(4) , c = 10.3000(3) , β = 93.4420(9)°, V = 1603.61(7) 3, (Z = 2) in 1 and a = 10.1473(2) , b = 10.9948(2) , c = 18.0952(5) , β = 93.0340(9)°, V = 2015.96(8) 3, (Z = 2) in 2. Single -crystal X-ray structure determinations revealed the presence of ionic complex, viz: one complex cation [trans-Cu(γ-pic) 2(H 2O) 4], two pts anions and two water molecules of crystallization in the complex 1 and neutral [trans-Cu(γ-pic) 4(pts) 2] and two water molecules of crystallization in 2. The crystal packing in both complexes is stabilized by OH⋯O, CH⋯O hydrogen bonds and CH⋯π interactions
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region

On the structure and origin of pressure fluctuations in wall turbulence: predictions based on the resolvent analysis
No full textWe generate predictions for the fluctuating pressure field in turbulent pipe flow by re-formulating the resolvent analysis of McKeon & Sharma (2010) in terms of the so-called primitive variables. Under this analysis, the nonlinear convective terms in the Fourier-transformed Navier-Stokes equations are treated as a forcing that is mapped to a velocity and pressure response by the resolvent of the linearized Navier-Stokes operator. At each wavenumber-frequency combination, the turbulent velocity and pressure field are represented by the most-amplified (rank-1) response modes, identified via a singular value decomposition of the resolvent. We show that these rank-1 response modes reconcile many of the key relationships between the velocity field, coherent structure (i.e., hairpin vortices), and the high-amplitude wall-pressure events observed in previous experiment and DNS. A Green’s function representation shows that the pressure fields obtained under this analysis correspond primarily to the fast pressure contribution arising from the linear interaction between the mean shear and the turbulent wall-normal velocity. Recovering the slow pressure requires an explicit treatment of the nonlinear interactions between the Fourier response modes. By considering the velocity and pressure fields associated with the triadically-consistent mode combination studied by Sharma & McKeon (2013), we identify the possibility of an apparent amplitude modulation effect in the pressure field, similar to that observed for the streamwise velocity field. However, unlike the streamwise velocity, for which the large scales of the flow are in phase with the envelope of the small-scale activity close to the wall, we expect there to be a ?/2 phase difference between the large scale wall-pressure and the envelope of the small-scale activity. Finally, we generate spectral predictions based on a rank-1 model assuming broadband forcing across all wavenumber-frequency combinations. Despite the significant simplifying assumptions, this approach reproduces trends observed in previous DNS for the wavenumber spectra of velocity and pressure, and for the scale-dependence of wall-pressure propagation speed
