This leads to some fundamental differences between the two. We uncover here the broken electron-hole symmetry in non-alternant NGRs as one fundamental difference closely related to distorted Dirac points (cones) and their diradical open-shell character. We also show by higher level calculations beyond common DFT, based on many-body (MPn) and coupled clusters (CCSD(T)) theory, that the alternant series of peri‑acenes (bisanthene, peri‑tetracene, peri‑pentacene, … etc.), contrary to opposite reports in the literature, have clearly closed singlet ground states, in contrast to their non-alternant isomers based on Stone-Wales (SW) defects. We suggest that this can be experimentally verified by sub-molecularly resolved STM images. The misconceptions in the literature are due to insufficient correlation. For non-alternant SW-NGRs/GNRs with antiaromatic rings the driving force for open-shell states and distorted Dirac points (involving localized electrons and delocalized holes) is antiaromaticity, which is a sufficient but not always necessary condition. This is in juxtaposition to the aromaticity of the alternant isomers with closed shell states. Thus, in both cases sublattice problems, such as sublattice imbalance or complete lack of sublattice would lead to open shell magnetic states; ferromagnetic (<em>e.g.</em> triangulenes), or antiferromagnetic respectively (<em>e.g.</em> SW3 × 2, SW4 × 2), in contrast to non-magnetic (diamagnetic) states for balanced sublattices (<em>e.g.</em> armchair GNRs, AGNRs).

This article reviews the recent advances in synthesis, characterization, and environmental applications of these demand-driven adsorbents from biomass and non-biomass sources. It first identifies relevant literature sources and knowledge gaps and then segmentalizes and scrutinizes the theme to elucidate contemporary carbon-based adsorbents. Conventional and advanced syntheses are highlighted. Current trends in adsorbents' characterization and remediation are also presented. The conventional AC synthesis includes one-step or two-step chemical or physical activation or a combinatorial synthesis of the two. Issues in the combinatorics are examined. Advanced techniques such as hydrothermal carbonization/activation and microwave-assisted irradiation are described, which may also involve one-step or two-step procedures. OCDs, including carbon nanotubes, carbon nanofibers, and carbon dots, mainly employ advanced syntheses, for example, nanotechnology. Currently, ACs and OCDs are mainly characterized using advanced techniques like scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), nitrogen (N₂) adsorption, and X-ray diffraction (XRD), which elucidate their structures, properties, and potential efficacies. Their applications for removing water, soil, and air pollutants are evaluated. The highest percent removal efficiency was activation type-specific, reflecting the precursor's nature, synthesis method, product properties, and quality. For instance, the chemical activation of neem leaves by H₃PO₄ activation and Fe nanoparticles from tea extracts were 100% successful for Pb²⁺and Cr⁶⁺, respectively, whereas physical activation of rice husk produced 91.8% success for Cr³⁺. However, their differential adsorptivities for other metals were moderate, with H₃PO₄ activation the lowest. Due to the high cost, tedious processes in producing and restoring ACs, and their non-selectiveness, researchers continually search for suitable alternatives, which this review considers. Also, applying artificial intelligence (AI) techniques in advancing novel ACs and OCDs for environmental remediation is discussed.
