Evaluation of graphen oxide nanoparticles efficacy in chromium and lead removal from aqueous solutions

مجله دانشگاه علوم پزشکی بیرجند, 2015
Background and Aim: Currently, several methods are used to remove heavy metals from aqueous solutions one of which is the adsorption process. Graphene oxide nanoparticles, due to their high adsorption capacity, have caused major concerns.

Quantum Transport in Nitrogen-Doped Nanoporous Graphenes. [PDF]

Small
Nanoporous graphenes are 2D arrays of graphene nanoribbons. Here, the quantum transport properties of nitrogen (N) doped nanoporous graphenes, combining N‐doped GNRs and non‐doped GNRs, are studied for the first time via Green's functions simulations.

NONCOMMUTATIVE GRAPHENE [PDF]

International Journal of Modern Physics A, 2013
We consider a noncommutative description of graphene. This description consists of a Dirac equation for massless Dirac fermions plus noncommutative corrections, which are treated in the presence of an external magnetic field. We argue that, being a two-dimensional Dirac system, graphene is particularly interesting to test noncommutativity.

Ionic Liquid Supported on Magnetic Graphene Oxide as a Highly Efficient and Stable Catalyst for the Synthesis of Triazolopyrimidines

Acta Chimica Slovenica, 2022
A novel sulfonic acid functionalized ionic liquid was prepared by anchoring 1-(propyl-3-sulfonate) vinylimidazolium hydrogen sulfate ([(CH2)3SO3HVIm]HSO4) on Fe3O4@GO. The prepared heterogeneous catalyst was characterized by XRD, FT-IR, EDX, SEM, VSM and

Immobilized nickel hexacyanoferrate nano particles on graphen for effective removal of Cs(I) ions from radionuclide wastes [PDF]

Journal of Water and Environmental Nanotechnology, 2023
In the current work synthesis and modification of graphene oxide with Nickel Hexa Ferrocyanide (NiHCF) nanoparticles has been reported. The Graphene oxide- Nickel Hexa Ferrocyanide (GO-NiHCF) was used as an adsorbent to remove Cesium (Cs) ions from a ...
