“…According to the theoretical calculations or MD simulations, the carbon honeycomb exhibits anisotropic thermal transport properties, i.e., a larger axial thermal conductivity than the transverse thermal conductivity. These in silico studies have also shown marked influences on the thermal conductivity of the honeycomb structures from various factors, such as the cell structures (or morphologies),141,142c mechanical strain,142b and temperature 142a. Figure b illustrates the specific axial and lateral thermal conductivity of a carbon honeycomb structure with varying density as obtained from density functional theory (DFT) calculations.…”

This work summarizes the recent progress on the thermal transport properties of 3D nanostructures, with an emphasis on experimental results. Depending on the applications, different 3D nanostructures can be prepared or designed to either achieve a low thermal conductivity for thermal insulation or thermoelectric devices or a high thermal conductivity for thermal interface materials used in the continuing miniaturization of electronics. A broad range of 3D nanostructures are discussed, ranging from colloidal crystals/assemblies, array structures, holey structures, hierarchical structures, to 3D nanostructured fillers for metal matrix composites and polymer composites. Different factors that impact the thermal conductivity of these 3D structures are compared and analyzed. This work provides an overall understanding of the thermal transport properties of various 3D nanostructures, which will shed light on the thermal management at nanoscale.

“…The atomic positions were optimized using the conjugate gradient method. The energy and force convergence criteria are set to be 10 -6 eV and only 0.18 eV/atom smaller than diamond but greater than some other carbon allotropes such as CKL [53] and CHC-2 [54]. [Detail structure parameters can be seen in Table S1 in Supplementary Information (SI)].…”

Nodal chain is a typical topological phase in nodal line semimetals. Here, we propose a new topological phase ---interlocking nodal chains, in which two sets of nodal chains are interlocked each other. It includes one-(1D), two-(2D) and threedimensional (3D) versions, which can be produced by a three-band model. The 2D and 3D interlocking nodal chains will evolve into some other phases, such as double concentric isolated (or intersecting) nodal rings, coexisting nodal chain and isolated (or intersecting) nodal rings. These phases exhibit diverse surface states and Landau levels, which implies that there are rich electronic and magnetic properties associating with them. Moreover, the 2D interlocking nodal chains and related phase transitions can be realized in a series of carbon networks under strain. Without strain, topological phase in the carbon structures is double concentric isolated nodal rings. A larger tensile strain leads to the phase transiting to an interlocking nodal chain, while the middle phase is a coexisting phase of a nodal chain and isolated nodal rings. In addition, stability and synthesis of the carbon networks are discussed.

“…While scaling 2D graphene up to its three-dimensional counterparts there are many significant challenges in maintaining the nature and intrinsic properties of individual graphene sheets in the resulting three-dimensional bulk structures. But the comprehensive theoretical studies of CHs [9,[16][17][18][19][20][21][22][23] proved their superb strength and stability. This strength remains at a high level but tunable with different cell sizes [17,24] and crucially depends on defectness of CH structures [25].…”

The paper presents a brief review of the recent developments in the field of absorption of atomic and molecular species in carbon cellular structures. Such absorbing objects can be distinctly recognized among a large family of carbon porous materials owing to potential and already observed in experiments very high capacity to soak and to keep inside different substances, which at usual conditions outside the porous matrices may often stay only in a gaseous form. High capacity filling is attained owing to single graphene-like walls separating different cells in the whole structures providing their lightweight. This property of cellular structures makes them very promising for numerous technological applications such as hydrogen storage in fuel cells and molecular sieving in membranes made from such structures or for their usage in microelectronics, photovoltaics and production of Li-ion batteries. Independently of the targeted applications gases are good candidates for probing tests of carbon matrices themselves.
