Abstract The rapidly increasing number of mobile devices, voluminous data, and higher data rate is pushing the development of the fifth-generation (5G) wireless communications. The 5G networks are broadly characterized by three unique features: ubiquitous connectivity, extremely low latency, and very high-speed data transfer via adoption of new technology to equip future millimeter band wireless communication systems at nanoscale and massive multi-input multi-output (MIMO) with extreme base station and device densities, as well as unprecedented numbers of nanoantennas. In this article, these new technologies of 5G are presented so as to figure out the advanced requirements proposed for the nanomaterials applied to antennas in particular. Because of massive MIMO and ultra-densification technology, conventional antennas are unable to serve the new frequency for smaller sizes, and the nanoantennas are used in 5G. The nanomaterials for nanoantennas applied in wideband millimeter waves are introduced. Four types of nanomaterials including graphene, carbon nanotubes, metallic nanomaterials, and metamaterials are illustrated with a focus on their morphology and electromagnetic properties. The challenges for the commercialization of 5G and nanomaterials are also discussed. An atomistic modeling approach is proposed for the development of novel nanomaterials applied in 5G and beyond.

Material advancement in technological development for the 5G wireless communications

The multiplicity of targets of the 5G and further future technologies, set by the modern societies and industry, lacks the establishment of design methods for the highly multidisciplinary application of wireless platforms for small cells. Constraints are set by the overall energy concept, structural safety and sustainability. Various Smart poles and Light poles exist but it is challenging to define the design drivers especially for a composite load-carrying structure. In this study, the design drivers of a composite 5G smart pole are determined and the connecting design between finite element modelling (FEM), signal penetration and computational fluid dynamics (CFD) for thermal analysis are reported as an interdisciplinary process. The results emphasize the significant effects of thermal loading on the material selection. The physical architecture, including various cutouts, is manipulated by the needs of the mmW radios, structural safety and the societal preferences of sustainable city planning, i.e., heat management and aesthetic reasons. Finally, the paint thickness and paint type must be optimized due to radome-integrated radios. In the future, sustainability regulations and realized business models will define the cost-structure and the response by customers.

Mesoporous Carbon: A Versatile Adsorbent and Catalyst with Techno-Economic and Life Cycle Perspectives

The imminent 5G technologies are rather different from many other technological waves that change the world and our everyday lives. The difference is that the interests of industry and technological leaps emerge faster than expected for the 5G revolution. The ever-increasing needs of wireless services, such as high-accuracy navigation, mobile services, the multifaceted infrastructure for autonomous vehicles, as well as various local services for individuals require significantly higher data throughput compared to current 3G and 4G technologies. The 5G technology relies on a wide span of frequency ranges also beyond the UHF spectrum, say 24–90 GHz, to overcome the challenges of latency, resilience, and bandwidth limits . In addition to the above-mentioned public services

Superactive carbon (SAC), having a high surface area of over 2500 m2/g, could be a superior choice for many applications. However, the manufacture of SAC in bulk quantities is challenging. To demonstrate the possibility of SAC manufacturing in large amounts, a techno‐economic assessment was performed. For that purpose, a new method utilizing a mixture of waste lignin, KOH and KCl was employed. The chemicals were recovered after use. The technical assessment was performed based on laboratory‐scale experimental findings, a simplified process diagram, and mass and heat balance calculations. The economic evaluation was assessed through the estimation of capital costs (CAPEX), operational costs (OPEX) and the minimum selling price (MSP). Moreover, to demonstrate the potential costs saving for the water treatment process, the performance of SAC for the removal of natural organic matter was compared with that of commercial active carbon. SAC was obtained at a minimized KOH amount (1 g/g) and chemicals were successfully recovered with a rate of 5–10% losses. The CAPEX, OPEX and MSP were found to be 4–21 million EUR, 1–9 million EUR/year and 4.4–2.9 kEUR/t for a 0.5–5.0 t/year production capacity, respectively, at a profitability requirement of 20% and a less than 5 year payback period. In addition, SAC demonstrated considerably higher adsorptive capacity for natural organic matter (600–900 mg total organic carbon/g) compared with commercial active carbon (40–50 mg total organic carbon/g), which could lead to substantial process savings. SAC manufacture through this method has been validated and the benefit for the potential application is sufficiently clear to promote the successful commercialization of SAC using lignin wastes. © 2022 The Authors.
