“…Activated carbons (AC) with high specific surface areas (SSA) are very important for a wide range of industrial applications where they are used as adsorbents for solvents, vapors and pollutants [ 1 , 2 , 3 , 4 ]. Their electric conductivity makes them highly promising electrodes for supercapacitors in energy storage applications [ 5 , 6 , 7 ], and as fillers for thermally conductive polymer composites [ 8 , 9 , 10 ].…”

Plasmonic nanoresonators consisting of a gold nanorod and a spherical silica core and gold shell, both coated with a gain layer, were optimized to maximize the stimulated emission in the near-field (NF-c-type) and the outcoupling into the far-field (FF-c-type) and to enter into the spasing operation region (NF-c*-type). It was shown that in the case of a moderate dye concentration, the nanorod has more advantages: smaller lasing threshold and larger slope efficiency and larger achieved intensities in the near-field in addition to FF-c-type systems’ smaller gain and outflow threshold, earlier dip-to-peak switching in the spectrum and slightly larger far-field outcoupling efficiency. However, the near-field (far-field) bandwidth is smaller for NF-c-type (FF-c-type) core–shell nanoresonators. In the case of a larger dye concentration (NF-c*-type), although the slope efficiency and near-field intensity remain larger for the nanorod, the core–shell nanoresonator is more advantageous, considering the smaller lasing, outflow, absorption and extinction cross-section thresholds and near-field bandwidth as well as the significantly larger internal and external quantum efficiencies. It was also shown that the strong-coupling of time-competing plasmonic modes accompanies the transition from lasing to spasing occurring, when the extinction cross-section crosses zero. As a result of the most efficient enhancement in the forward direction, the most uniform far-field distribution was achieved.

“…Graphene is utilized to increase the thermal conductivity of epoxy glue with minor adjustment in the heat transfer rate as a potential conduction filler. Chen et al [ 129 ] examined the influence of filler loading on composite thermal conductivity. The findings demonstrated that graphene in any form is more successful at increasing the thermal conductivity of composites than carbon nanotubes and other carbon-based nanofillers (shown in Figure 11 ).…”

The application of epoxy adhesive is widespread in electronic packaging. Epoxy adhesives can be integrated with various types of nanoparticles for enhancing thermal conductivity. The joints with thermally conductive adhesive (TCA) are preferred for research and advances in thermal management. Many studies have been conducted to increase the thermal conductivity of epoxy-based TCAs by conductive fillers. This paper reviews and summarizes recent advances of these available fillers in TCAs that contribute to electronic packaging. It also covers the challenges of using the filler as a nano-composite. Moreover, the review reveals a broad scope for future research, particularly on thermal management by nanoparticles and improving bonding strength in electronic packaging.

“…Because of such high thermal and electrical conductivity, CNT and graphene have great potential for enhancing the conductive property of textiles. In an interesting study, Chen, et al [15] studied the effect of different carbon-based nanomaterials and their aspect ratios on the thermal conductivity of epoxy nanocomposites, where the thermal conductivity increased with increasing filler concentration and aspect ratio. Moreover, graphene oxide (GO) showed the best thermal conductivity, while carbon black showed the most inferior performance [15].…”

Conductive metallic nanomaterialsConductive metals (such as silver, copper, gold, aluminum, and tin) and metal oxide (TiO 2 and ZnO) nanomaterials exhibit great promise as alternatives to conventional conductive materials [6][7][8]. These conductive metal nanomaterials (nanoparticles or nanowires) can be incorporated in different polymers to make conductive polymer nanocomposites, which can be used further for making conductive fibers or coated textiles. However, in polymer matrices, generally, metal nanowires exhibit better conductivity in comparison to metal nanoparticles because of their better conductive network at lower concentrations and less inter-particle junctions in the case of nanowires [9]. Conductive nanoparticles such Ag, ZnO and TiO 2 dissipate the static charge of synthetic fibers because of their good electro-conductive property and hence, these nanoparticles can be used to develop antistatic fabrics [10][11]. Carbon-based nanomaterialsDifferent carbon-based nanomaterials such as 2D graphite and graphene, 1D CNTs, carbon black etc. are extensively used to increase conductivity of polymer and textiles [12][13][14]. The electrical conductivity, of pure CNT can be as high as 10 6 to 10 7 S m -1 and for pure graphene, it can be up to 10 5 S m -1 . On the other hand, the thermal conductivity value of CNT may vary between 2800-6000
