Summary: Quantum-mechanical calculations of electron transport in ideal graphene nanoribbons show that the transport gap predicted by noninteracting theories vanishes when the long-range Coulomb interaction between electrons is considered. However, the gap reappears if a ribbon is connected to wider leads, typically in experimental setups using lithographically patterned graphene ribbons. The gap is determined by scattering at the lead-to-ribbon interface, which can be captured by noninteracting theory.

Summary: This study investigated the diameter-dependent synthesis of GNRs using SWCNTs of different average diameters, and found that the width of GNRs can be tailored by the diameter of SWCNTs. Particularly, SWCNTs with an average diameter of 1.3 nm produced the highest yield of 6 and 7 armchair GNRs, indicating potential for high-yield production of certain GNRs in large scale applications.

Summary: Graphene nanoribbons (GNRs) are promising materials for nanoscale electronic devices due to their exceptional stability and unique electronic and optical properties. In this study, we investigate the formation process of 7-GNRs on Au(111), Ag(111), and Cu(111) substrates using 10,10'-Dibromo-9,9'-bianthracene (DBBA) as the precursor. X-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS) are utilized to track the reaction pathways. Our results demonstrate that the substrate reactivity plays a crucial role in the growth behavior of GNRs.

Summary: The study reveals that hydrogen and fluorine-passivated graphene nanoribbons exhibit plastic deformation when twisted beyond the threshold torsional strain, while hydrogen-passivated nanoribbons show high elasticity. Additionally, fluorine-passivated nanoribbons are found to be more sensitive to torsional strain, resulting in a smaller bandgap.

Summary: The bilateral final/baseline threshold level changes of lower cranial nerve MEPs were found to be significantly correlated with postoperative swallowing function deterioration in patients with skull base and brainstem tumors. An increase in bilateral final/baseline threshold level change of more than 20% was predictive of permanent swallowing deterioration, especially in patients with poor swallowing function preoperatively.

Summary: In this study, a novel CDK4/6 inhibitor YF-PRJ8-1011 was designed and synthesized, which exhibited more potent antitumor activity against patient-derived DMG tumor cells compared with palbociclib. The results showed that YF-PRJ8-1011 could inhibit the growth of DMG cells in vitro and in vivo, penetrate the blood-brain barrier, and significantly inhibit the growth of DMG tumors and prolong the overall survival of mice. In addition, YF-PRJ8-1011 combined with radiotherapy also showed more significant inhibition of DMG xenograft tumor growth than radiotherapy alone.

Summary: In this paper, the authors study a class of linear-quadratic mean field games with common noises and their corresponding N-player games. They analyze the limiting behavior of the representative player and obtain their optimal control in a feedback form. The mean field equilibrium is determined by the Nash certainty equivalence system. By assuming the non-degeneracy of idiosyncratic noises, they solve the N-player game and prove convergence results and the propagation of chaos property.

Summary: Interactions between collective multi-layered cells and an off-axis high-order Bessel beam (HOBB) were studied. The generalized Lorenz-Mie theory was used to derive the expansion of HOBB. Multiple scattering of collective multi-layered nanoparticles was obtained based on the additional theorem and considering the tangential continuous boundary conditions. The effectiveness of the present theory and codes was proven by comparing with simulations obtained from CST software. Numerical results regarding the effects of various parameters on the scattering of aggregated multi-layered particles were displayed, which may contribute to understanding the optical scattering characteristics of complex-shaped aggregated multi-layered biological cells and have important applications in manipulating multi-layered biological structures.

Summary: Nanoscale zero-valent iron (nZVI) has high potential for remediating contaminated groundwater. Sulfidation is a promising approach to enhance nZVI's lifetime. Density functional theory (DFT) was used to study the impact of sulfidation on the hydrophobicity of Fe surfaces. The results show that surface hydrophobicity is mainly determined by the coverage of sulfur (S).
