This article adds a critical lens to the vicissitudinous public remembrance of the comfort women in the People’s Republic of China (PRC) and the oscillating representations of comfort women in Chinese documentary films. First, it probes how the violated bodies of comfort women on the screen constantly challenge and disrupt the entrenched gender norms in the interstices of the PRC’s official paradigms of “national humiliation” and “national greatness.” Then, it examines the distinctive film esthetics and documentary ethics of Chinese director Guo Ke’s documentary films Thirty Two (2014) and Twenty Two (2017), given that the latter harvested record-breaking box office sales and incited heated online discussions of the comfort women issue in China. In particular, this article scrutinizes how Guo’s esthetically appealing, politically non-confrontational, and ethically provocative approach helps constitute survivors’ private, gendered memories and encourages the viewers to contemplate his minimalist narratives. In a broader sense, this article contributes to the discussions of gender, nationalism, war remembrance, and documentary filmmaking in contemporary China.

This article examines the transnational poetics embedded in Chinese American poet Wing Tek Lum's 2012 collection The Nanjing Massacre: Poems. Borrowing from Jahan Ramazani's concept of transnational poetics, I show how a transnational perspective reveals the cross-cultural content and formal experiments in Asian American poetry. I examine Lum's intercultural representations of two groups of people: Japanese perpetrators and comfort women. Lum's poetic construction of Japanese perpetrators explores ordinary Japanese soldiers' mentalities, adapts Japanese folklore, and engages with Japanese verse haiku. Lum's portrayals of comfort women reveal how the women have been reduced to objects and symbols of national humiliation, and I argue that his juxtaposition of the Nanjing Massacre with other historical traumas emphasizes universal, war-inflicted sexual trauma. Lum's representations of Japanese perpetrators and comfort women work together to undermine nationalist uses of Nanjing Massacre history memory and instead emphasize transnational war traumas and gender oppression. Situated at the intersection of Asian American poetry studies and studies of the Nanjing Massacre, this article hopes to push beyond narrowly US-bound models of criticism for Asian American poetry and highlights how Lum mobilizes an intercultural way of approaching the Nanjing Massacre.

Polymeric carbon nitride (PCN)‐based single‐atom catalysts represent the most promising catalysts for photocatalytic hydrogen evolution (PHE), which, however, still suffer from reduced thermodynamic stability because of the metal‐induced heptazine skeleton distortion. Herein, hydroxylated Rh single‐atom antennas (Rh‐SAAs) connected by dual oxygen‐bridges are constructed on the surface of PCN matrix, which brings great structural advantages in avoiding skeleton distortion and increasing stability compared to the traditional direct coordination of metal atoms onto PCN. The optimal PCN‐Rh‐0.5 delivers an average PHE rate of 3409 µmol g −1  h −1 , 32.5 times that of the PCN/Pt benchmark. More importantly, it achieves an ultralong stable operation time (192 h) with a higher amount of hydrogen production per unit mass than those of the state‐of‐the‐art single‐atom catalysts and other high‐stability catalysts (≥50 h) under the same conditions. Insights into the mechanism reveal the key role of the electron pump effect induced by interband trap states composed of hybridized Rh 4d/O 2p orbitals that can propel the directed electron transfer toward Rh‐SAAs. As a result, the improved charge separation efficiency and lifetime, along with the strong protonation capability with dual oxygen‐bridges, trigger a dual‐cycle reaction path, thereby achieving high PHE activity and stability.

An emerging method for effectively improving the catalytic activity of metal oxide hybrids involves the creation of metal oxide interfaces for facilitating the activation of reagents. Here, we demonstrate that bilayer vesicles formed from a hexavanadate cluster functionalized with two alkyl chains are highly efficient catalysts for the oxidation of 3,3＇,5,5＇-tetramethylbenzidine （TMB） with H2O2 at room temperature, a widely used model reaction mimicking the activity of peroxidase in biological catalytic oxidation processes. Driven by hydrophobic interactions, the double-tailed hexavanadate-headed amphiphiles can self-assemble into bilayer vesicles and create hydrophobic domains that segregate the TMB chromogenic substrate. The reaction of TMB with H2O2 takes place at the interface of the hydrophilic and hydrophobic domains, where the reagents also make contact with the catalytic hexavanadate clusters, and it is approximately two times more efficient compared with the reactions carried out with the corresponding unassembled systems. Moreover, the assembled vesicular system possesses affinity for TMB comparable to that of reported noble metal mimic nanomaterials, as well as a higher maximum reaction rate.

The quantum Hall effect can be substantially affected by interfacial coupling between the host two-dimensional electron gases and the substrate, and has been predicted to give rise to exotic topological states. Yet the understanding of the underlying physics and the controllable engineering of this interaction remains challenging. Here we demonstrate the observation of an unusual quantum Hall effect, which differs markedly from that of the known picture, in graphene samples in contact with an antiferromagnetic insulator CrOCl equipped with dual gates. Two distinct quantum Hall phases are developed, with the Landau levels in monolayer graphene remaining intact at the conventional phase, but largely distorted for the interfacial-coupling phase. The latter quantum Hall phase is even present close to the absence of a magnetic field, with the consequential Landau quantization following a parabolic relation between the displacement field and the magnetic field. This characteristic prevails up to 100 K in a wide effective doping range from 0 to 1013 cm−2.Interfacing graphene with an antiferromagnetic insulator CrOCl enables the observation of strong interfacial coupling in the quantum Hall regime.

The controllable fabrication of patterned p -type and n -type channels with precise doping control presents a significant challenge, impeding the realization of complementary metal-oxide-semiconductor (CMOS) logic using a single van der Waals material. However, such an achievement could offer substantial benefits by enabling continued transistor scaling and unprecedented interlayer interconnect technologies. In this study, we devise a precise method for two-dimensional (2D) semiconductor substitutional doping, which allows for the production of wafer-scale 2H-MoTe 2 thin films with specific p -type or n -type doping. Notably, we extend this approach to the synthesis of spatially selective doped 2H-MoTe 2 thin films via a one-step growth method, facilitating the monolithic integration of p -type and n -type semiconductor channels. Leveraging this advancement, we successfully fabricate a chip-sized 2D CMOS inverter array that demonstrates excellent device performance and yield. Collectively, these findings represent a significant stride towards the practical incorporation of 2D semiconductors in very large-scale integration technology. The fabrication of n - and p -type semiconducting channels based on the same layered material would simplify the implementation of 2D electronics. Here, the authors report a spatially selective doping method for the synthesis of wafer-scale p - and n -type 2H-MoTe 2 thin films, and their application for the realization of complementary 2D transistor and inverter arrays.

The realization of graphene gapped states with large on/off ratios over wide doping ranges remains challenging. Here, we investigate heterostructures based on Bernal-stacked bilayer graphene (BLG) atop few-layered CrOCl, exhibiting an over-1-GΩ-resistance insulating state in a widely accessible gate voltage range. The insulating state could be switched into a metallic state with an on/off ratio up to 10 7 by applying an in-plane electric field, heating, or gating. We tentatively associate the observed behavior to the formation of a surface state in CrOCl under vertical electric fields, promoting electron–electron (e–e) interactions in BLG via long-range Coulomb coupling. Consequently, at the charge neutrality point, a crossover from single particle insulating behavior to an unconventional correlated insulator is enabled, below an onset temperature. We demonstrate the application of the insulating state for the realization of a logic inverter operating at low temperatures. Our findings pave the way for future engineering of quantum electronic states based on interfacial charge coupling. Here, the authors report evidence of unconventional correlated insulating states in bilayer graphene/CrOCl heterostructures over wide doping ranges and demonstrate their application for the realization of low-temperature logic inverters.

Objective This study aims to discuss anxiety in mediating role between bullying victimization and adolescent internet addiction, and the moderating role of family support between bullying victimization and adolescent anxiety. Methods A cross-sectional study was conducted in 5 provinces of China by convenience sampling from February to March 2024. A total of 1395 participants (599 boys and 796 girls) with an average age of 15.86 ± 0.74 years were included in the final analysis. Subjective data on bullying victimization, internet addiction, anxiety, and family support were collected and analyzed. A moderated mediation model was constructed. Results After controlling for age and gender, bullying victimization was found to be a significant predictor of internet addiction (β = 0.130, p  < 0.001). Anxiety has a complete mediating effect between bullying victimization and adolescent internet addiction. Specifically, bullying victimization significantly predicted adolescent anxiety (β = 0.264, p  < 0.001). anxiety significantly predicted adolescent internet addiction (β = 0.417, p  < 0.001). Family support alleviated the relationship between bullying victimization and anxiety (β= -0.032, p  < 0.05). Conclusions Bullying victimization can predict internet addiction through anxiety in adolescents, and family support can alleviate the predictive relationship between bullying victimization and adolescent anxiety. It is suggested that guardians should provide adequate support to adolescent bullying victimization in order to reduce the negative impact of bullying victimization on adolescents and prevent the occurrence of internet addiction.
