“…Pores of scaffolds varied from 100 μm to about 1,000 μm diameter, as illustrated in Figures 6A,B . After coating with RGO, elastic modulus of 3D RGO/Alg scaffolds increased 3.8-fold compared to Alg-only scaffolds ( Supplementary Figure S2 ), which is consistent with the previously reported reinforcing property of graphene ( Güler and Bağc1, 2020 ). The RGO/Alg scaffold was electrically conductive as further evidence of successful RGO coating, with a sheet resistance of 1.5 kΩ/sq (±0.14).…”

Tissue engineering, based on a combination of 3D printing, biomaterials blending and stem cell technology, offers the potential to establish customized, transplantable autologous implants using a patient's own cells. Graphene, as a two-dimensional (2D) version of carbon, has shown great potential for tissue engineering. Here, we describe a novel combination of graphene with 3D printed alginate (Alg)-based scaffolds for human adipose stem cell (ADSC) support and osteogenic induction. Alg printing was enabled through addition of gelatin (Gel) that was removed after printing, and the 3D structure was then coated with graphene oxide (GO). GO was chemically reduced with a biocompatible reductant (ascorbic acid) to provide electrical conductivity and cell affinity sites. The reduced 3D graphene oxide (RGO)/Alg scaffold has good cytocompatibility and can support human ADSC proliferation and osteogenic differentiation. Our finding supports the potential for the printed scaffold's use for in vitro engineering of bone and other tissues using ADSCs and potentially other human stem cells, as well as in vivo regenerative medicine.

“…Graphene is a single-layer sheet of sp 2 -hybridized carbon atoms with a honeycomb structure. It is a two-dimensional material with outstanding electrochemical properties compared with CNTs ( Elmekawy et al., 2017 ), being one of the strongest and thinnest materials available ( Güler and Bağcı, 2020 ). This review focuses on CNTs, which were first fabricated in 1991 ( Iijima, 1991 ) and are formed by rolling up a single graphene sheet (single-walled carbon nanotubes, SWCNTs) or a series of concentric graphene sheets (multi-walled carbon nanotubes, MWCNTs).…”

“…Different methods are currently can be applied to carbonmetal systems to obtain composite structure: Al alloy reinforced by GNFs was successfully prepared via powder metallurgy approach [63]; aluminum-matrix composites reinforced with graphene nanoflakes were fabricated by cryomilling and hot extrusion processes [64]; ball milling and hot pressing to reinforce Cu matrix by GNFs; spark plasma sintering (SPS) and then hot rolling [65] to name a few.…”

Simulation of metal-graphene composites by molecular dynamics: a review

et al. 2020

View full text Add to dashboard Cite

Fabrication of the new composite materials with improved mechanical characteristics is of high interest nowadays. Simulation methods can considerably improve understanding of the interaction between the graphene and metal phase, even in the atomistic level. In the present work, the simulation of graphene-metal composites by molecular dynamics is reviewed. Both experiments and simulation results have shown that the metal matrix can be reinforced with graphene flakes, and the overall mechanical properties of the final composite structure can be significantly improved. Two basic types of metal-graphene composite structures are considered: (i) metal matrix strengthens by graphene flakes and (ii) crumpled graphene (the porous structure that consists of crumpled graphene flakes connected by van der Waals forces) as the matrix for metal nanoparticles. Several different types of interatomic potentials like pairwise Lennard-Jones or Morse or complex bond order potentials for the description of metal-carbon interaction are presented and discussed. It is shown that even simple interatomic potentials can be effectively used for the molecular dynamics simulation of graphene-metal composites. Particular attention is paid to graphene-Ni composites obtained by deformation and heat treatment from crumpled graphene with pores filled with Ni nanoparticles. It is shown, that high-temperature compression can be effectively used for the fabrication of the graphene-Ni composite with improved mechanical properties.
