The metals used in this study represent two classes based on the type of bonding formed with graphene. Ti and Ni form chemisorbed interfaces (strong bonding) with graphene and high TBC is expected while Au forms physisorbed interfaces (weak bonding). The measured TBC at M-G-M interfaces ...
- Now we model graphene using tight-binding theory. The relevant atomic orbital is the single $\pi$ orbital which is left unfilled by the bonding electrons, and which is normal to the plane of the lattice. If we denote the the orbital on atom $i$ with spin $\sigma$ as $(i,\sigma)...
Here, a multilayered graphene (MLG) as a top electrode is successfully implanted, via dry bonding, onto the top organic layer of transparent OLED (TOLED) with flexion patterns. The performance of the TOLED with MLG electrode is comparable to that of a conventional TOLED with a semi-...
which increases the probability of bonding between the underlying layers. The removal of the first layer with low bonds density improved the graphene strength by about 40%. Also, removal of the five upper layers has increased the ultimate tensile strength from about 4 GPa to about 8 GPa,...
The type of bonding in these MAX phases is a hybrid of covalent, metallic and ionic [51]. Since the MXenes are obtained from their parent MAX phases, the M atoms are similarly arranged in a close-packed fashion with the X atoms in the octahedral interstices [52]. Generally, the MXenes...
or graphdiyne, holey graphene not only has the ideal 2D semiconducting properties but also has nonlinear sp bonding and a special π-conjugated structure, which offers promising applications in optoelectronic, energy harvesting, gas separation, catalysis, water remediation, sensor, and energy-related fie...
Without the guidance of preformed templates, GO sheets can self-assemble during hydrothermal reduction processing to form a 3D porous structure through the restoration of π-π bonding between monolayers. For example, Wu et al. have designed a mild hydrothermal method of 2D graphene self-assembly ...

According to the first-principles calculations, the well-bonded heterostructure between MgO and rGO is the main reason for the strong bonding force. Moreover, the prepared rGO# coating showed a superior photothermal effect, which brings a new strategy to the treatment of bone tumors with Mg-...
Graphene oxide (GO) is an electrical insulator due to disruption of its sp2 bonding network, while reduced graphene oxide (rGO) contains less oxygen and hence less disruption in its sp2 bonding network. Many attempts have been made to make rGO-polymer nano-composite to enhance the mechanical, ...
