Controlling the configuration of graphene oxide (GO) phases, or rather their smaller synthetic analogs, graphene (oxide) quantum dots (GOQDs), is crucial for any of their commonly used applications, ...

The macroscopic alignment of dilute dispersions of graphene oxide can be controlled, with extremely large optical sensitivity, through the application of weak electric fields. Song and ...

Contamination with manganese is a frequent issue with other forms of graphene oxide that can cause issues when using graphene oxide in biological systems. The low levels of manganese and high purity ...

Apr 07, 2020: Physicists produce stable water-based graphene dispersion (Nanowerk News) Umeå researchers show how activated graphene, activated carbons and other hydrophobic carbons can be dispersed ...

An evaporating colloidal particle–laden droplet leaves behind a ring-like residue after drying. We routinely observe this ubiquitous phenomenon for dried coffee drops; thus, it is known as the "coffee ...

Graphene oxide, which is a product of graphite oxidation, ... Or, more water can be added to the dough to transform it into a high-quality GO dispersion on demand.

A graphene sensor trained by machine learning can now taste like a human, identifying both basic and complex flavors with ...

Researchers show how graphene oxide suspended in water biodegrades in a reaction catalyzed by a human enzyme, with the effectiveness of the breakdown dependent on the colloidal stability of the ...

A team of researchers report in the Proceedings of the National Academy of Sciences on a new graphene-based sensor design ...
