Summary: Improvements in carbon-based conductors can impact the development of new electronic and optoelectronic devices, potentially offering significant weight savings compared to copper, which is important in mass sensitive applications such as aircraft design. Chemical doping is seen as the most likely route to high specific conductivity carbon-based wiring, with the testing of potassium tetrabromoaurate showing potential complications due to differences in the nominal dopant molecule and the 'in situ' configuration of the dopant species. Ab initio modeling of KAuBr4 doping suggests that the dopant is most effective in a disassociated form, but overall, KAuBr4 doping is unlikely to produce high specific conductivity CNT wiring.

Summary: In this study, ab initio calculations were performed to investigate the energetic, dynamical, and electronic properties of polymerized (2n + 1, 0) (n = 2, 3, 4) sing wall carbon nanotubes. The results showed that the equilibrium energies of the carbon allotropes studied were comparable to existing carbon structures. Phonon band spectrum calculations confirmed their dynamical stability, while ab initio molecular dynamics simulations confirmed their thermal stability. The electronic properties of these carbon structures varied, with CNT(5,0) and CNT(7,0) carbon exhibiting nodal line semimetal behavior and CNT(9,0) carbon behaving as a semiconductor. The study provided insights into the relationship between real space crystalline structures and momentum space band topologies.

Summary: Density functional theory calculations were conducted to investigate the interaction between (10,0) GaPNT and FeCl3 and CrO3 compounds, revealing that FeCl3 and CrO3 interact strongly with GaPNT through chemisorption, leading to significant changes in electronic and structural properties. The adsorption of FeCl3 on GaPNT resulted in the appearance of localized states in the gap region, causing a reduction in band gap, while CrO3 adsorption outside GaPNT increased the band gap. FeCl3 adsorption inside GaPNT turned the system metallic, unlike the other systems which remained semiconductors.

Summary: The research demonstrates that BC3 nanotubes have significant sensor properties for detecting poisonous cyanogen gas, with stable complexes formed and efficient recovery time. The absorption of cyanogen gases leads to a substantial change in the band gap of BC3NTs, making them sensitive and selective sensor even in the presence of other molecules. The study also shows that BC3NTs are more convenient and sensitive compared to BC(3)NSs for detecting cyanogen gas in practical applications.

Summary: In this study, the structure and electronic properties of puckered GeS nanotubes were investigated using first-principles density functional theory calculation. The results show that the GeS nanotubes, both armchair and zigzag, are semiconductor materials with an adjustable band gap. The band gap increases with the tube diameter and strain can induce interesting variations in the band gap. Furthermore, the elastic properties of the stable armchair GeS nanotubes were studied and their Young's modulus was calculated.

Summary: In the past decade, controlled assembly of clean-edged and defect-free graphene nanoribbons has been achieved through surface-assisted reactions using well-defined molecular precursors. Recently, the successful realization of a bisanthene-like quantum dot with pairs of pentagon-heptagon defects has been accomplished. By studying the electronic properties of systems based on the concatenation of SW-bisanthene motifs, it has been shown that nanoribbons with SW-defects maintain their semiconducting character. Notably, frontier levels exhibit behaviors that affect the carrier mobilities of both electrons and holes. Additionally, the electronic transport properties of nanojunctions composed of graphene nanoribbons with a localized distribution of SW-defects compatible with the geometry of the corresponding bisanthene-like blocks have been investigated, and it has been found that the transmission spectrum is sensitive to the position and concentration of SW-defects.

Summary: This article proposes a taxonomy for two-dimensional single-layer carbon allotropes, where each allotrope is assigned a unique symbol based on its geometry. The naming scheme is demonstrated for known structures and additional topology-allowed carbon systems. The symbol provides easy access to geometrical features and simplifies the classification of structures in the literature, which often have arbitrary names. This naming scheme will aid future studies on this class of systems. The energetic properties of the structures are also compared using consistent numerical parameters. The naming scheme can be extended to carbon systems with mixed hybridizations and other non-carbon 2D systems.

Summary: This study reports the synthesis of magnetic graphene oxide (GO Fe3O4) with different amounts of iron nanoparticles for the adsorption of furosemide (FUR). The optimal adsorbent was found to be GO Fe3O4 1:1, with a removal percentage and adsorption capacity of 96.15% and 96.91 mg g-1, respectively, at pH 3.0 and 293.15 K. The process was influenced by initial concentration, adsorbent dosage, and pH, while the ionic strength had minimal effect on the performance of GO Fe3O4 1:1. Sips and PSO models were the best fit for the experimental data, indicating a heterogeneous surface. GO Fe3O4 1:1 exhibited high removal percentage even after several cycles of adsorption/desorption.

Summary: A comparative investigation into the extraction of bisphenol A using alpha, beta, and gamma cyclodextrins was performed with computational and spectroscopic assistance. A mu-solid-phase extraction podium and HPLC-UV were used for extraction and analysis. Beta-cyclodextrin was selected as the adsorbent for bisphenol A extraction based on density functional theory calculations and spectroscopy data. Optimization of various parameters led to a limit of detection of 0.70 ng/ml and a limit of quantification of 2.31 ng/ml with beta-cyclodextrin in real source water samples, demonstrating the development of a novel, simple, sensitive, and economic analytical method.
