The graphene oxide (GO) loaded spiky gold (AuNS) nanocomposites were prepared by electrostatic interaction between negatively-charged GO nanosheets and positively-charged AuNS by the assistance of chitosan as linker molecules. The AuNS/GO nanocomposites exhibit a red-shift in the extinction spectra and a reduction in the zeta potential compared to those of the pristine AuNS due to the presence of oxygen-containing functional groups in GO.

In this study, rGO/NiCo2S4 composite materials were successfully synthesized by hydrothermal method. The properties of obtained materials were systematically characterized using XRD, SEM, EDX, and Raman techniques. The electrochemical performance of the materials was evaluated through cyclic voltammetry (CV) and Galvanostatic charge-discharge (GCD) measurements.

The rGO/CueCu2O deposited on the electrode surface was confirmed by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, confocal microscopy, and electrochemical characterization. The analytical performance of the proposed rGO/CueCu2O-modified electrode was also compared with the CuO/rGO-modified electrode using commercial CuO nanoparticles.

While triboelectric nanogenerators (TENGs) made of biomaterials are becoming significant components of self-charged monitoring healthcare systems, most of them show low output performance and poor durability. Herein, a surfactant-free graphene oxide-polylactic acid (GO/PLA) nanocomposite with customizable honeycomb patterns was, for the first time, prepared via a scalable two-step solution method to achieve a power-boosted biocompatible TENG.

In this investigation, a new nanocomposite as a nanocarrier based on functionalized graphene oxide was synthesized by reaction of tetraethylenepentamine and chlorosulfonic acid with functional groups on the surface of GO. The synthesized nanocomposite was characterized by FT-IR, XRD TGA, FE-SEM, EDAX, TEM, and AFM analysis. To explore the potential of nanocomposites in drug delivery, the loading and releases of quercetin as an anticancer drug were investigated.

Thermostable and highly water-soluble polymers are essential for polymer flooding — one of the most effective methods used in the enhanced oil recovery (EOR) in hightemperature (HT) offshore reservoirs. In this research, the copolymerization reaction of acrylamide (AM) and N-vinylpyrrolidone (NVP) monomers were performed via a freeradical mechanism induced by gamma-rays (γ-rays) irradiation.

The spectroscopic studies reveal that the GO–Fe 3 O4 nanocomposite is a highly efficient adsorbent for MB removal from aqueous solution, providing an adsorption capacity of 172.6 mg/g, and the equilibrium for MB adsorption is attained in ∼70 min. Moreover, it is a magnetically separable and reusable material for MB removal from water, preserving 87% of its initial efficiency after 5 successive runs.

High density polyethylene (HDPE) was compounded with thermally exfoliated graphene oxide (TEGO) by thermokinetic mixing in a short time. High shear rates during the compounding process provided high exfoliation and proper dispersion of graphene layers in the polymer matrix. Different TEGO/polymer ratios were used to get efficient melt mixing. Structural analysis by spectroscopic techniques confirmed the exfoliation of TEGO sheets and the coverage of their surfaces by HDPE chains.
