“…Interestingly, the small-diameter NTs are found to be semiconducting. This behavior is different than what is found in carbon NTs, BC 2 N, and Silicene NTs [80][81][82]. Hybridization is the key to understanding the metallic behavior in carbon NTs at small diameters [80].…”

We explore the possibility and potential benefit of rolling a Si2BN sheet into single-walled nanotubes (NTs). Using density functional theory (DFT), we consider both structural stability and the impact on the nature of chemical bonding and conduction. The structure is similar to carbon NTs and hexagonal boron-nitride (hBN) NTs and we consider both armchair and zigzag Si2BN configurations with varying diameters. The stability of these Si2BN NTs is confirmed by first-principles molecular dynamics calculations, by an exothermal formation, an absence of imaginary modes in the phonon spectra. Also, we find the nature of conduction varies semiconducting, from semi-metallic to metallic, reflecting differences in armchair/zigzag-type structures, curvature effects, and the effect of quantum confinement. We present the detailed characterization of how these properties lead to differences in both the bonding nature and electronic structures.

With the global energy demand on the rise, lithium-ion batteries (LIBs) have attracted more attention as they play a pivotal role in electrification revolution. This research intends to investigate how does the application of nanotechnology have an impact on the current commercialized LIBs among electric vehicles through different components such as cathode, anode and electrolyte of the battery itself under the carbon neutral context in the next decade. The major trends for cathode material are NMC/NCA though efforts have been made to reduce the reliance on cobalt; anode material is mainly graphite-based, and the mainstream electrolyte remains in liquid organic solvent thats electrochemically unstable. Through current research findings presented in different research, a summary of the current progress made in the nanotechnology field for better battery performance will be generated, and a proposed future research focus and innovations with lingering challenges like energy density and sustainability issues for battery recycling will be carried out.
