Electrochemical Response of 3D-Printed Free-Standing Reduced Graphene Oxide Electrode for Sodium Ion Batteries Using a Three-Electrode Glass Cell.

Graphene and its derivatives have been widely used to develop novel materials with applications in energy storage. Among them, reduced graphene oxide has shown great potential for more efficient storage of Na ions and is a current target in the design of electrodes for environmentally friendly Na ion batteries. The search for more sustainable and versatile manufacturing processes also motivates research into additive manufacturing electrodes.

Graphene-Based Materials, Their Composites, and Potential Applications.

Since its isolation in 2004, monolayer graphene has attracted enormous attention within the scientific community, the industry, and the general public owing to its exceptional properties (electrical, optical, thermal, and mechanical) and prospects [...

Applications of Ceramic/Graphene Composites and Hybrids.

Research activity on ceramic/graphene composites and hybrids has increased dramatically in the last decade. In this review, we provide an overview of recent contributions involving ceramics, graphene, and graphene-related materials (GRM, i.e.

Reinforced 3D Composite Structures of γ-, α-AlO with Carbon Nanotubes and Reduced GO Ribbons Printed from Boehmite Gels.

The ability of boehmite to form printable inks has sparked interest in the manufacturing of 3D alumina (AlO) and composite structures by enabling direct ink writing methods while avoiding the use of printing additives. These materials may exhibit high porosity due to the printing and sintering procedures, depending on the intended application. The 3D-printed porous composite structures of γ-AlO and α-AlO containing 2 wt.

Protein adsorption and in vitro behavior of additively manufactured 3D-silicon nitride scaffolds intended for bone tissue engineering.

Highly porous scaffolds of SiN are fabricated by direct ink writing method (Robocasting) with a pattern of macroporous cavities of 650-700μm. Two different SiN ink compositions regarding the oxide sintering aids (namely, YO, AlO, and SiO) are tried. Both inks reach solid volume fractions of ~0.

Remarkable Effects of an Electrodeposited Copper Skin on the Strength and the Electrical and Thermal Conductivities of Reduced Graphene Oxide-Printed Scaffolds.

Architected Cu/reduced graphene oxide (rGO) heterostructures are achieved by electrodepositing copper on filament-printed rGO scaffolds. The Cu coating perfectly contours the printed rGO structure, but isolated Cu particles also permeate inside the filaments. Although the Cu deposition conveys a certain mass augment, the three-dimensional (3D) structures remain reasonably light (bulk density ≅ 0.
