Researchers manage to induce "artificial magnetic texture"

The electrodes revealed a surprise — the magnet induced an artificial magnetic texture in the graphene that persisted even in areas of the graphene away from the magnet. Put simply, the intimate contact between the two objects caused the normally nonmagnetic carbon to behave differently, exhibiting magnetic properties similar to common magnetic materials like iron or cobalt.

Graphene oxide is not conducive to the long-term protection of steel, and the residual chloride ions in polyaniline, especially in industrial production, accelerate the corrosion of coatings. Therefore, we prepared the modified graphite oxide and phytic acid-doped polyaniline to improve the protection time of graphene oxide coatings and the corrosion resistance of polyaniline.

Nanomaterials

In this study, the physicochemical and surface properties of the GO–Ag composite promote a synergistic antibacterial effect towards both Gram-negative Escherichia coli (E. coli) and Gram-positive Staphylococcus aureus (S. Aureus) bacteria. GO–Ag NPs have a better bactericidal effect on E. coli (73%) and S. Aureus (98.5%) than pristine samples (pure Ag or GO). Transmission electron

Graphene additives promote 'eco

We also learned that the degree of corrosion resistance for a given coating depends on the amount of both the graphene and the second, synergistic, corrosion-protection pigment. The optimum amounts differ for each second pigment used, and finding them has to be done experimentally, because so far no general theory has been established.

Mixed‐Valence Single‐Atom Catalyst Derived from

The synergistic effect of Cu(II) and Cu(I) is the essential part in the reaction mechanism. The developed strategy opens the door to a broad portfolio of other SACs via their coordination to various functional groups of graphene, as demonstrated by successful entrapment of Fe III /Fe II single atoms to carboxy‐graphene.

Graphene/Polymer Nanocomposites

Graphene has emerged as a subject of enormous scientific interest due to its exceptional electron transport, mechanical properties, and high surface area. When incorporated appropriately, these atomically thin carbon sheets can significantly improve physical properties of host polymers at extremely small loading. We first review production routes to exfoliated graphite with an emphasis on top
