Summary: In this paper, a new variational form is developed to simulate the propagation of surface plasmon polaritons on graphene sheets. Graphene is treated as a thin sheet of current with an effective conductivity, and modeled as a lower-dimensional interface. A novel time-domain finite element method is proposed to solve this graphene model, which couples an ordinary differential equation on the interface with Maxwell's equations in the physical domain. Discrete stability and error estimate are proved for the proposed method. Numerical results are presented to demonstrate the effectiveness of this graphene model for simulating the surface plasmon polaritons propagating on graphene sheets.

Summary: In this study, explicit formulas for the Casimir energy of parallel sheets composed of conducting planes with tensorial conductivities were derived using the scattering matrix approach. Formulas for the Casimir energy and force acting on the planes within a stack of graphene were obtained by solving the recurrence relations. The binding energy in the graphene stack with graphite interplane separation was also calculated and found to be E-ib = 9.9 meV/atom. Notably, the Casimir force on graphene sheets decreases rapidly for planes beyond the first one, with the force on the second graphene layer being 35 times smaller than that experienced by the first layer.

Summary: The use of magnesium alloys is a new trend in the automotive industry, but joining these alloys is challenging due to their low formability at room temperature. In this research, a novel joining process called hole hemming is developed for attaching magnesium and aluminum alloy sheets, without the need for heating or rivets. By characterizing the fracture limits of the materials and using finite element analysis, a process for joining was designed and the influence of process parameters on mechanical interlock was investigated.

Summary: Recently, there has been increasing attention to the sheet joining process for building lightweight structures. Clinching technology is a green joining method that is energy-saving and cost-efficient. The main challenge in conventional clinching using a round punch is the unsatisfactory joint strength. To improve the mechanical properties of clinched joints, the tools and process parameters of the clinching process need to be optimized. This study investigates the influence of forming forces on the joining quality of clinched joints using a stepped punch through experimental methods and analyzes the geometric parameters, failure modes, mechanical characteristics, and energy absorption in detail. A comparison with clinched joints created with a round punch concludes that the usage of a stepped punch is meaningful in creating joints with higher neck thickness. At the same forming force, the maximum increments in tensile and shear strength of the joints created by the stepped punch are 26.1% and 59.2%, respectively.

Summary: Based on dendrimers, a series of polyphenol compounds (P1, P2, and P3) were coordinated with iron (III) (Fe3+) to investigate the effect of polyphenol structures on their T1 contrast performance. These new Fe3+-based complexes, featuring regular amplification of their phenolic hydroxyl groups, exhibit enhanced longitudinal relaxivity (r1) due to proton exchange facilitated by a hydrogen-bonding network. Furthermore, these designed Fe3+-based complexes demonstrate good T1 contrast effect in vitro and in vivo. Modifying the coordination structure of Fe3+-based contrast agents can potentially improve their relaxivity properties and facilitate the development of excellent magnetic resonance imaging agents for disease diagnosis.

Summary: In this study, a synchronous nucleation pseudopyrolysis method was used to confine Fe/FeOx ultrafine nanoparticles (UNPs) in intact porous carbon nanorods (IPCNs). The strong physical and chemical confinement effects between UNPs and carbon were achieved through moderate thermal kinetics and abundant oxygen defects. This strong confinement greatly benefited subsequent chemical transformations and resulted in different Fe-based UNPs with excellent electrochemical performance. As a proof of concept, FeSe UNPs in IPCNs exhibited superior lithium storage performance with an ultrahigh and stable capacity of 815.1 mAh g-1 at 0.1 A g -1 and 379.7 mAh g-1 at 5 A g-1 for 1000 cycles.

Summary: The misuse of antibiotics has led to the emergence of drug-resistant bacteria, posing a serious public health threat. Antibacterial photodynamic therapy (aPDT) serves as a promising strategy to combat drug-resistant microbes. However, conventional photosensitizers have limited efficacy due to the complex bacterial infectious microenvironment (BIME). In this study, a BIME-triggered nanoplatform, HA-CY, was developed to enhance aPDT efficacy by exploiting the specific conditions of BIME.

Summary: The Cu2SnTe3 (CST) nano-reagent is able to effectively inhibit tumor growth through a strong synergetic effect in chemodynamic therapy (CDT), photodynamic therapy (PDT), and photothermal therapy. CST nanoparticles convert H2O2 into *OH and generate O-1(2) through surface-catalyzed reactions and light irradiation-induced electron pair separation, leading to oxidative stress accumulation in tumor cells. The nanoparticles also possess catalase-like activity, enhancing O-2 levels within hypoxic tumors and the production efficiency of O-1(2) by PDT.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
