Summary: This paper proposes a machine learning-based framework, called MORM, to address the challenge of insufficient coverage of the Pareto front in many-objective optimization problems. The framework reversely maps the objective values to decision variables using a learning model constructed on the initial PF set. It generates candidate solutions using inexpensive generative techniques and covers the initial PF efficiently through iteratively generated non-dominated candidate solutions.

Summary: This work conducted field tests to explore the causes of failure of connecting bolts between the axle box front cover and axle box body on high-speed trains. The results revealed the 20th-order polygonization of the wheel and drastic vibration of the front cover at a speed of 300 km/h. The bench test reproduced the unique and drastic vibration phenomenon and confirmed the responsibility of wheel polygonization for the vibration of the front cover. Operational Modal Analysis and theoretical analysis verified the existence of non-linear vibration of the front cover under 20th-order polygonization. The study also investigated the cause of bolt failure and the dynamic characteristics of the front cover resulting from different wheel polygon orders.

Summary: The Front Cover illustrates that metals with more destabilized interfacial water molecules can act as efficient electrocatalysts for the hydrogen evolution reaction (HER). Despite a relatively high activation energy, a high reaction rate can be achieved through proton tunneling by having high values of preexponential factor. While the destabilization of the proton's solvation sphere is intuitive in acidic electrolytes, a more complex mechanism is involved in alkaline media.

Summary: In this study, the DNA-like double helix is used to represent the structure of parameterized quantum circuit, which corresponds to the design of a revised multiobjective genetic algorithm. The split circuit fragment at the end of the double helix represents the optimization of the parameterized quantum circuit structure. The two guide lines colored by red and blue represent the two objectives (gradient and cost) to be optimized.

Summary: Experimental results showed that the erosion rates on the cover of the inner front pole in a 12.5 kW Hall thruster are most sensitive to low voltage and current conditions, with increasing magnetic field strength leading to higher erosion rates, particularly near the inner radius. Additionally, the energy distributions of ions generated by the hollow cathode may also impact certain erosion trends.

Summary: Designing engineering structures like nanocages, shells, and containers through self-assembly of colloids is a challenging problem. This work proposes a simple model for the subunit, which leads to the formation of monodispersed spherical cages or containers. The model with only one control parameter can be used to design cages with the desired radius.

Summary: The cycling lifespan and coulombic efficiency of lithium-ion batteries are crucial for high C-rate applications. The Li-ion concentration plays a crucial role in determining the mechanical integrity and structural stability of electrodes. This study focuses on graphite as the working electrode and establishes an experimental system to investigate the mechanical properties of composite graphite electrode at different C-rates. Considering the effect of Li-ion concentration in stress analysis is found to be significant.

Summary: This study investigates the influence of intramolecular pi-pi interactions on the electronic transport capabilities of molecules. By designing and analyzing three pi-conjugated molecules, the researchers observe that different pi-conjugated structures have varying effects on electron transport. The findings provide a theoretical foundation for designing single-molecule electronic devices with multiple electron channels based on intramolecular pi-pi interactions.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

It is found that shock compaction waves exhibit a distinct two-step structure, with the formation of faster precursor waves that travel ahead of the main compaction waves. The complexity of the shock Hugoniot curve of the tested nanomaterial is described, and the effect of initial porosity on the compressed states is demonstrated.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.

Summary: Inspired by the successful transfer of freestanding ultrathin films of SrTiO3 and BiFeO3, this study assessed the structural stability and investigated the electronic, optical, and thermoelectric properties of a group of two-dimensional perovskite-type materials called perovskenes. The findings revealed that these materials are wide bandgap semiconductors with potential application in UV shielding. Moreover, they exhibit better electrical and thermal conductivity at high temperatures, enabling efficient power generation in thermoelectric devices.
