Summary: Single-walled carbon nanotubes (SWCNTs) exhibit large nonlinear deformations without permanent damage and have important implications in science and technology. This study investigates the nonlinear dynamics of a curved SWCNT oscillator model when two control parameters are varied simultaneously. The study identifies the existence of a quint points lattice merged in a domain of periodic dynamics, the coexistence of different stable states for the same parameter combinations and different initial conditions, and the existence of infinite self-organized generic stable periodic structures (SPSs) merged into chaotic dynamics domains. The findings highlight the complexity of the dynamics in damped-driven curved SWCNTs and its potential impact on theoretical and experimental applications.

Summary: By using Ar-ion etching to remove the top layer of the electrode surface before nanotube placement, the contact resistance at the nanotube-metal interface can be significantly reduced. This results in a tenfold decrease in the median ON-resistance of transistors and a more than two orders of magnitude decrease in the interquartile range of resistance values.

Summary: Engineering anisotropic nanostructures of isotropic FCC metals like Au, Pt, or Pd requires a symmetry-breaking mechanism and a judicious selection of capping agents. The formation mechanism of ultrathin single-crystalline Pt nanowires was investigated using electron microscopy, showing that ligand binding to the Pt surface plays a crucial role in morphology and growth direction control. Adopting a ligand-exchange mechanism can separate Pt nanowire bundles into individual wires, crucial for improving their electrocatalytic activity.

Summary: The review focuses on the advancements made in the semiconductor-nanocrystal-sensitized, three-component upconversion system over the past 5 years. It discusses the critical roles of the triplet photosensitizer, mediator, and emitter in determining the overall quantum efficiency of the system, as well as the mechanisms involved in triplet energy transfer between the components. Through optimization of the sensitizer, mediator, and emitter, an increase in anti-Stokes shift and total quantum efficiency can be achieved.

Summary: This study compares the application of modified microbial flocculants (MMFs) with conventional organic flocculants in mitigating membrane fouling. The results show that MMF has better performance in pollutant removal and membrane fouling control. The study also reveals that cake layer formation is the main mechanism of membrane fouling and MMF can reduce the accumulation of foulants on the membrane surface. Correlation analysis indicates that total phosphorus, polysaccharide, zeta potential, and particle size have the greatest correlation with fouling resistance.

Summary: This study aims to investigate the dynamic response associated with the impact of a kinetic projectile on the internal structure of an artificial satellite. Through ground damage testing and finite element dynamic simulation, we determined the lateral effect and penetration performance of the projectile, and studied its dynamic behavior when penetrating a honeycomb sandwich panel and multi-layer plates. The ballistic limit velocity of the projectile was found to be 150 m/s, and the deformation of the opening had little relationship with the projectile velocity. Additionally, it was observed that the launch velocity required to meet the damage requirements of the multi-layer plates was within 325 +/- 25 m/s, with higher initial velocities resulting in reduced damage area.

Summary: This research examines the impact of Buddhism on mergers & acquisitions (M&As) performance using data from 4622 M&A transactions of Chinese public firms between 2004 and 2018. The findings provide ample evidence that acquirers located in regions with a higher intensity of Buddhism achieve better short-term and long-term performance after the merger. Furthermore, the study reveals that state ownership plays a crucial role in mitigating this effect, and the value creation is driven by higher deal completion rates and fewer violation cases for acquiring firms. Finally, the study addresses the issue of endogeneity, and the results remain unchanged.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
