“…Thus, CFms are actively investigated as heat sink materials because of their good properties, such as high thermal stability, high thermal/electrical conductivity, low density, high porosity and high specific surface area [4,5]. CFms are suitable materials for applications in phase-change materials, such as in latent heat thermal energy storage and lithium-ion batteries [6][7][8][9].CFms are prepared from thermoplastic graphitizable precursors, such as petroleum-derived, coal-derived and mesophase pitch (MP). In particular, MP has been widely used as an appropriate precursor for high-performance carbon materials due to its attractive properties, i.e., high coke yield, low softening point, and high fluidity [10].…”

Carbon foams (CFms) are of crucial importance in electrical and mechanical devices due to their high thermal conductivity used for eliminating high heat flow and maintaining low temperatures [1]. The most common CFms are types of aluminum alloys, copper and diamond. However, the mechanical properties of metal-based heat sink materials are difficult to control at temperatures over 550°C [2,3]. Thus, CFms are actively investigated as heat sink materials because of their good properties, such as high thermal stability, high thermal/electrical conductivity, low density, high porosity and high specific surface area [4,5]. CFms are suitable materials for applications in phase-change materials, such as in latent heat thermal energy storage and lithium-ion batteries [6][7][8][9].CFms are prepared from thermoplastic graphitizable precursors, such as petroleum-derived, coal-derived and mesophase pitch (MP). In particular, MP has been widely used as an appropriate precursor for high-performance carbon materials due to its attractive properties, i.e., high coke yield, low softening point, and high fluidity [10]. Previous processes used a blowing technique, or pressure release, to produce foam from MP. These manufacturing techniques have many disadvantages: the volume fraction of generated cells cannot be precisely controlled, and controlling the shape and distribution of cells is difficult, if not impossible [11]. To better control and tailor the structure of such foams, polymer template methods are actively being researched. Hydrogel template methods are suitable for preparing high-strength CFms due to their large quantities of carbon precursors and the pressure generated through hydrogel shrinkage via heat treatment [10,12]. However, their mechanical strengths are low because of their high porosities.One method for improving the mechanical strength of CFms is adding fillers with a high mechanical strength. Several additives have been used as fillers, including carbon nanofibers, short carbon fibers, graphite and graphene nanosheets [13][14][15][16][17][18][19][20][21][22]. In particular, graphite has beneficial properties that include high lubricating ability, heat resistance, corrosion resistance and thermal/electrical conductivity. It has been widely applied in various fields as a highly functional component with efficient properties. Additionally, the theoretical thermal conductivity of graphite is high, with values ranging from 3000 to 5000 W/mK, and its mechanical strength is 1100 GPa [23,24]. The thermal/mechanical properties of CFms could be improved by the addition of carbon nanofillers with good thermal/mechanical properties through the formation of network structures comprising CFms and carbon nanofillers. Furthermore, carbon nanofillers can be carbon-coated (C-coated) to improve the interfacial bonding with metal. For example, Katzman [25] showed that carbon fibers could be C-coated using amorphous pitch to improve the interfacial bonding with metal oxide and prepare a carbon-fiber-reinforced metal-matrix compo...

Rhenium disulfide (ReS2) is a two dimensional (2D) group VII transition metal dichalcogenide (TMD). It is attributed with structural and vibrational anisotropy, layer independent electrical and optical properties, and metal-free magnetism properties. These properties are unusual compared with more widely used group VI-TMDs e.g. MoS2, MoSe2, WS2 and WSe2. Consequently, it has attracted significant interest in recent years and is now being used for a variety of applications including solid state electronics, catalysis, and, energy harvesting and energy storage. It is anticipated that ReS2 has the potential to be equally used in parallel with isotropic TMDs from group VI for all known applications and beyond.Therefore, a review on ReS2 is very timely. In this first review on ReS2, we critically analyze the available synthesis procedures and their pros-cons, atomic structure and lattice symmetry, crystal structure and growth mechanisms with an insight to the orientation and architecture of domain and grain boundaries, decoupling of structural and vibrational properties, anisotropic electrical, optical and magnetic properties impacted by crystal imperfections, doping and adatoms adsorptions, and the contemporary applications in different areas.
