Abstract Purpose To determine the impact of low versus atmospheric oxygen tension during only the pre-maturation phase of biphasic capacitation in vitro maturation. Methods The study involved sibling oocytes (532 cumulus-oocyte complexes [COCs] from 20 participants [mean age 29.5 ± 2.5 years]) with polycystic ovary syndrome undergoing CAPA-IVM without gonadotrophins. After oocyte pick-up (OPU), COCs were randomized...

Abstract Kombucha is a traditional fermented tea rich in organic acids and shows potential as a carbon source for Shewanella species to generate electricity in microbial fuel cells (MFCs). This research investigated the applicability of kombucha post-fermentation medium as a substrate to support the growth of Shewanella putrefaciens and electricity generation in recirculating MFCs. A preliminary growth study showed...

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...
