Graphene has drawn attention as a scientific curiosity owing to its record conductivities, strength and thermal properties.

Graphene-based nanoparticle composites attract considerable attention due to their unique properties and the large variety of possible applications, such as sensing, energy storage, and catalysis. The ...

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 ...

New findings reveal that organosulfate groups, not carboxyls, control graphene oxide's surface charge in water, challenging long-standing models and reshaping its chemical profile. (Nanowerk Spotlight ...

The rGO technique and its related processes have their foundations in the Brodie method, which later became the Hummers method. Variants of the technique then developed on from the Hummers method. The ...

Movable structures can be manufactured from flexible, tear-resistant graphene oxide films, which simultaneously provide ...

McGill University engineers have developed ultra-thin materials that can move, fold, and reshape themselves, ...
