Abstract This study investigates the key social, psychological, and technological factors influencing social commerce adoption among Gen Z university students in Vietnam. It examines how social support constructs, trust, and technophilia contribute to forming social commerce intention and translating it into actual usage behavior. Guided by the Stimulus-Organism-Response model and the Theory of Planned Behavior,...
Abstract GaOOH/reduced graphene oxide (rGO) composites are investigated for UVC photodetection with a defect-controlled photoresponse. The morphology and crystallinity of GaOOH grown on rGO are strongly influenced by the Ga(NO3)3 concentration. Excess precursor induces GaOOH aggregation, reducing the effective GaOOH/rGO interfacial area and generating trap states in GaOOH. These traps act as recombination centers that shorten...
Abstract The development of sustainable catalytic systems for biomass valorization is of great importance in the transition toward renewable energy and green chemical processes. In this study, a noble-metal-free Bi2O3-Cr2O3 catalyst supported on nitrogen-doped carbon nanotubes (N-CNT) was developed for the aerobic conversion of carbohydrates into 2,5-diformylfuran (DFF) using molecular oxygen as the oxidant. The catalytic...
Abstract Missing data is a commonly encountered problem in practice that can degrade the performance of predictive models and distort statistical inference. Many advanced imputation techniques suffer from a lack of interpretability, operating as “black boxes”. This paper introduces Parameter-based Imputation via Cycle-ensemble Averaging (PICA), a novel framework that first estimates distributional parameters directly from...
Abstract Developing cost-effective, durable, and efficient bifunctional electrocatalysts is essential for advancing green hydrogen production. Here, we report a rapid, one-step, room-temperature, corrosion-driven strategy for directly constructing nickel-iron layered double hydroxides (NiFe LDH) on nickel foam (NF), where the NF serves as both the conductive substrate and the sole Ni source. In an Fe3 + -ethylene glycol...
Abstract Temporal knowledge graphs (TKGs) represent real-world facts evolving over time by incorporating the multirelational structure of knowledge graphs with temporal dimensions. While extensions of graph convolutional networks, such as relational and composition-based variants, have demonstrated strong capabilities in modeling graph-structured data, effectively capturing both symmetric and asymmetric relational dependencies, their application to TKG reasoning...
Abstract Transition-metal oxide memristors are promising for neuromorphic computing, yet most SPICE models overlook material-specific effects such as oxygen stoichiometry and non-pinched hysteresis. Here, we systematically study CrOx/TiOy memristors fabricated under controlled oxygen concentrations (10%–50%) and propose an improved SPICE-compatible model. The devices exhibit oxygen-dependent resistive switching, retention, and pulse-driven plasticity, with optimal performance at 40%...
Abstract The mechanism of thermally enhanced luminescence (TEL), such as thermally activated delayed fluorescence (TADF) and thermally stimulated delayed phosphorescence (TSDP), is of fundamental importance in the molecular design of emissive transition-metal complexes, as it can enable bright emission with enhanced radiative rate for high-performance organic light-emitting diodes (OLEDs). It is essential to resolve the...
Abstract Social media has emerged as a prominent factor in shaping public perceptions. However, significant gaps remain in our understanding of the complex interplay between social media and human-nature relationships, including for mangrove ecosystems. We assessed how mangroves have been discussed and perceived on social media by analysing 649,495 Twitter/X posts between 2010 and 2022....
Abstract The current paradigm of plasmon-enhanced up-conversion photoluminescence (PE-UCPL) lays in intimate coupling domains of noble metal and lanthanide-doped nanoparticles. An increase of incident electromagnetic field and radiative emission rates is the key reason for the UCPL enhancement by the primitive plasmonic architectures of metal nanospheres/nanorods/nanoshells. Based on the hypothesis of precise tuning surface plasmon...
