Enhanced methylene blue adsorption using zirconate alginate/graphene oxide/UiO-67 aerogel spheres: Synthesis, characterization, kinetic studies, and adsorption mechanisms.

International Journal of Biological Macromolecules, 2023
Zirconium alginate/graphene oxide (ZA/GO) hydrogel spheres were prepared by crosslinking sodium alginate and GO with Zr4+. Then Zr4+ on the surface of the ZA/GO substrate acted as the metal nucleation site of the UiO-67 crystal and interacted with the ...

Improved p-chlorophenol adsorption onto copper-modified cellulose nanocrystal-based hydrogel spheres.

International Journal of Biological Macromolecules, 2023
The present study intended to develop efficient hydrogel spheres in treating simulated wastewater contaminated with p-chlorophenol. Herein, copper-modified nanocellulose was grafted onto alginate to produce eco-friendly hydrogel spheres to utilize as a ...

The pseudo-two-dimensional dynamics in a system of macroscopic rolling spheres

, 2020
We study in this work the dynamics of a collection of identical hollow spheres (ping-pong balls) that rest on a horizontal metallic grid. Fluidization is achieved by means of a turbulent air current coming from below.

A space-sacrificed pyrolysis strategy for boron-doped carbon spheres with high supercapacitor performance.

Journal of Colloid and Interface Science, 2021
Targeting the potential application of morphological carbon in electrode materials, a space-sacrificed pyrolysis strategy was applied for the preparation of boron-doped carbon spheres (B-CSs), using commercial triphenyl borate (TPB) as carbon and boron ...

On Some Compact Spacelike Submanifolds of Pseudo-sphere

Geometriae Dedicata, 2004
Let \(M\) be an \(n\)-dimensional compact connected space-like submanifold of the pseudo-sphere \(S^{n+m}_p= \{x\in\mathbb{R}^{n+m+1}_p: \langle x,x\rangle= {1\over c}\}\), where \(\mathbb{R}^{n+m+1}_p\) is the real vector space with an inner product of signature \(p\), \(1\leq p\leq m\). Let \(M\) have flat normal bundle and a parallel one-dimensional

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.
