    Abstract Two-dimensional fullerene networks have been synthesized in several forms, and it is unknown which monolayer form is stable under ambient conditions. Using first-principles calculations, I show that the believed stability of the quasi-tetragonal phases is challenged by mechanical, dynamic, or thermodynamic stability. For all temperatures, the quasi-hexagonal phase is thermodynamically the least stable. However, the relatively high dynamic and mechanical stabilities suggest that the quasi-hexagonal phase is intrinsically stronger than the other phases under various strains. The origin of the high stability and strength of the quasi-hexagonal phase can be attributed to the strong covalent C-C bonds that strongly hold the linked C

    Abstract ABSTRACT Enhancing the physical health of college students is the fundamental guarantee of cultivating high-quality talents. In order to understand the influencing factors of college students' physical health and carry out targeted intervention, this study aims to analyze the factors affecting college students' physical health. Through the construction of physical health evaluation index and its influencing factors evaluation index, the importance of different indicators is evaluated by using the analytic hierarchy process, and a questionnaire about college students' physical health and its influencing factors is designed. The results show that the factors affecting college students' physical health include students' own factors, school factors, and others. At the same time, the insufficient construction of public sports facilities and the lack of first-class sports venues and equipment are also the reasons for the decline of college students' physique. Therefore, we can intervene in the students' physical health from the aspects of raising the students' awareness about physical exercise and Ensuring the construction of school sports facilities. It is hoped that this study can provide some reference for the empirical analysis and intervention research on the influencing factors of college students' physical health.

    Abstract Two-dimensional fullerene networks have been synthesized in several forms [Hou et al., Nature 606, 507 (2022)], and it is unknown which monolayer form is stable at ambient condition. Using first principles calculations, I show that the believed stability of the quasi-tetragonal phases is challenged by mechanical, dynamic or thermodynamic stability. For all temperatures, the quasi-hexagonal phase is thermodynamically least stable. However, the relatively high dynamic and mechanical stabilities suggest that the quasi-hexagonal phase is intrinsically stronger than the other phases under various strains. The origin of the high stability and strength of the quasi-hexagonal phase can be attributed to the strong covalent C$-$C bonds that strongly hold the linked C$_{60}$ clusters together, enabling the closely packed hexagonal network. These results rationalize the experimental observations that so far only the quasi-hexagonal phase has been exfoliated experimentally as monolayers.

    Abstract Photocatalytic water splitting can produce hydrogen in an environmentally friendly way and provide alternative energy sources to reduce global carbon emissions. Recently, monolayer fullerene networks have been successfully synthesized [Hou $\textit{et al., Nature}$ $\textbf{2022}$, 606, 507], offering new material candidates for photocatalysis because of their large surface area with abundant active sites, feasibility to be combined with other 2D materials to form heterojunctions, and the C$_{60}$ cages for potential hydrogen storage. However, efficient photocatalysts need a combination of a suitable band gap and appropriate positions of the band edges with sufficient driving force for water splitting. In this study, I employ semilocal density functional theory and hybrid functional calculations to investigate the electronic structures of monolayer fullerene networks. I find that only the weakly screened hybrid functional, in combine with time-dependent Hartree-Fock calculations to include the exciton binding energy, can reproduce the experimentally obtained optical band gap of monolayer C$_{60}$. All the phases of monolayer fullerene networks have suitable band gaps with high carrier mobility and appropriate band edges to thermodynamically drive overall water splitting. In addition, the optical properties of monolayer C$_{60}$ are studied, and different phases of fullerene networks exhibit distinct absorption and recombination behavior, providing unique advantages either as an electron acceptor or as an electron donor in photocatalysis.

    Abstract With the increasing development of low-permeability reservoirs, the significance of conformance control treatment has risen considerably. To address the conflict between injectability and plugging performance, as well as to enhance the deep migration capacity of conformance control agents, preformed submicron crosslinked polymer coils (SCPCs) have been manufactured using aqueous solution dispersion polymerization. Fourier transform infrared and scanning electron microscopy were employed to examine the chemical structure and micromorphology, while particle size distribution, zeta potential, rheological, and filtration properties were analyzed. The effectiveness of conformance control was confirmed through the parallel core displacement. The effective particle size of SCPCs was at a submicron level (500~800 nm). SCPCs exhibit a transitional threshold concentration between gel and sol states (0.25 wt%~0.5 wt%). SCPCs can efficiently block the 1.2 μm microporous filter membrane. The filtration time is up to 67.8 min. SCPCs can improve the water absorption rate of lower permeability cores from 21.21% to 57.89% with a permeability difference of 5. Therefore, SCPCs have good injectability, plugging performance, and deep migration capacity and can be used for conformance control in low-permeability reservoirs.
