Synthesis, characterization and photocatalytic activity of ZnO flower and pseudo-sphere: Nonylphenol ethoxylate degradation under UV and solar irradiation

Journal of Alloys and Compounds, 2016
Abstract ZnO particles (flower and pseudo sphere) were synthesized via precipitation route and characterized using X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive X-ray analysis (EDX), Fourier transform infra-red (FTIR) spectroscopy, Atomic force microscopy (AFM), Particle size analyzer and UV–visible techniques.

Hard-sphere/pseudo-particle modelling (HS-PPM) for efficient and scalable molecular simulation of dilute gaseous flow and transport [PDF]

Molecular Simulation, 2016
Continuum methods are not accurate enough for flows at high Knudsen numbers, whereas rigorous molecular dynamics ( MD) methods are too costly for simulations at practical dimensions.

MAGNETIC GROUP ON THE PSEUDOSPHERE

International Journal of Modern Physics B, 1992
The quantum mechanics of a particle moving on a pseudosphere under the action of a constant magnetic field is studied from an algebraic point of view. The magnetic group on the pseudosphere is SU(1, 1). The Hilbert space for the discrete part of the spectrum is investigated.

Path integral for relativistic Aharonov–Bohm–Coulomb system on the pseudo-sphere

Journal of Mathematical Physics, 2001
The Green’s function for relativistic spinless Aharonov–Bohm–Coulomb (ABC) system on the pseudo-sphere Λ(2) is calculated using Kleinert’s path integral representation for relativistic spinless particles. The energy spectrum and the corresponding wave functions are extracted for bound and scattering states.

Codimensionm isometric immersions between pseudo-spheres

Geometriae Dedicata, 1995
The author investigates isometric immersions \(f:S^n_p\to S^{n+m}_{p+1}\), for \(n-p\geq 2m\). Here \(S^m_k\) is the pseudosphere of radius 1 in the pseudo-Euclidean space \(\mathbb{R}^{m+1}_k\). The metric on \(\mathbb{R}^{m+1}_k\) is given by \(\langle x,y\rangle=-\sum^k_{i=1}x_iy_i+ \sum^{m+1}_{i=k+1} x_iy_i\), for \(x=(x_1,\dots,x_{m+1})\), \(y ...

THE XY-MODEL ON A PSEUDO-SPHERE: A RENORMALIZATION GROUP ANALYSIS

Modern Physics Letters B, 1990
We present some simple arguments to indicate that the XY model defined on a space of constant negative curvature is disordered at all non-zero finite temperatures. This corroborates a result which Wilczek and Callan arrived at recently.

Families of Gauss indicatrices on smooth surfaces in pseudo-spheres in the Minkowski 4-space

Journal of Singularities, 2010
We study families of Gauss indicatrices on surfaces in pseudo-spheres in the Minkowski 4space and obtain the generic local models of the congurations of the foliations determined by the bres of their principal curvatures functions.

L_\ell -Biconservative Timelike Hypersurfaces in the Lorentz Pseudo-Sphere

We study L_\ell-biconservative timelike hypersurfaces in the Lorentz pseudo-sphere, defined by isometric immersion \xi: M^n_1\to\mathbb{S}_1^{n+1}. The operator L_\ell, defined in terms of the \ell-th Newton transformation, generalizes the Laplacianand arises as the linearized operator of the (\ell+1)-th mean curvature.A hypersurface is said to be L_ ...
