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.

Prediction and optimization of adsorption properties for Cs+on NiSiO@NiAlFe LDHs hollow spheres from aqueous solution: Kinetics, isotherms, and BBD model.

Journal of Hazardous Materials, 2020
In this work, novel NiSiO@NiAlFe layered double hydroxides (LDHs) hollow spheres were prepared by hydrothermal method. It was worth noting that LDHs' grafting towards NiSiO hollow spheres could avoid the LDHs' aggregation, and thus enhanced the material ...

Adsorption of Cr(VI) from aqueous solutions using novel activated carbon spheres derived from glucose and sodium dodecylbenzene sulfonate.

Science of the Total Environment, 2020
Cr(VI) is a common wastewater pollutant. Various adsorbents including carbon-based materials are used for the removal of Cr(VI) owing to their high adsorption capacity.

Adsorption behavior and mechanism of Mg/Fe layered double hydroxide with Fe3O4-carbon spheres on the removal of Pb(II) and Cu(II).

Journal of Colloid and Interface Science, 2019
Mg/Fe layered double hydroxide loaded with Magnetic(Fe3O4) carbon spheres (MCs@Mg/Fe-LDHs) was firstly synthesized by a facile in-situ co-precipitation method to remove Pb(II) and Cu(II) pollution.

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.

Modified carbon spheres as universal materials for adsorption of cationic harmful substances (paraquat and dyes) in water

, 2020
In this study, carbon spheres (CS) with ideal particle sizes (~700 nm) and regular morphology were prepared by extending the Stober method followed by oxidative modification of nitric acid to obtain carbon spheres (MCS) with abundant carboxyl and nitryl ...

Hollow carbon spheres/graphene hybrid aerogels as high-performance adsorbents for organic pollution

Separation and Purification Technology, 2019
The development of high-performance adsorbents for water purification is of utmost importance. Herein, we report the construction of a 3D graphene hybrid aerogel integrated with hollow carbon spheres via a two-step synthetic strategy.
