Linkage Engineering Boosts Battery Performance of Two‐Electron Phenothiazine‐Based Polyamide Cathodes

ABSTRACT Organic cathode materials based on redox‐active p‐type phenothiazine have attracted considerable interest for lithium‐organic batteries (LOBs) due to their high operating voltage and tunable chemical structures. Nevertheless, their practical application is often limited...

Does teacher-student closeness mediate the effect of teacher enthusiasm on self-efficacy? A diary study among Chinese teachers

Teacher self-efficacy is critical for effective teaching, highlighting the importance of identifying its predictors. Drawing on the Broaden-and-Build Theory of positive emotions and the Prosocial Classroom Model, this study examined whether teacher enthusiasm predicts teacher sel...

Effects of combined training on inflammatory biomarkers in middle-aged and older adults: a systematic review and meta-analysis

Chronic low-grade inflammation is a key factor in aging and age-related diseases. With population aging, effective anti-inflammatory interventions were increasingly needed. Combined aerobic and resistance training (CART) has emerged as a promising non-pharmacological approach; ho...

Data-driven identification of economic drivers and regional disparities of ecological resilience in china’s urban agglomerations: an explainable deep learning framework

As key spatial carriers for regional economic growth and ecological protection, urban agglomerations’ ecological resilience is critical to regional risk adaptation and sustainable development. This study examines 92 prefecture-level and above cities in China’s five major urban ag...

Teachers' AI use and student learning outcomes in higher education: The roles of learning engagement and teacher AI literacy

Purpose As generative artificial intelligence (AI) becomes increasingly integrated into higher education, teachers are playing a central role in transforming AI technologies into educational value. However, empirical evidence regarding whether and how teachers' AI use improves st...

A new species of the genus Macrobiotus (Tardigrada: Macrobiotidae) from Southeastern China

Zhang, Pin, Sun, Xi-Zhai (2014): A new species of the genus Macrobiotus (Tardigrada: Macrobiotidae) from Southeastern China. Zoological Systematics 39 (2): 224-228, DOI: 10.11865/zs20140203

Rh-Catalyzed [3 + 2] Cascade Annulation of Aromatic Acids with Oxabicyclic Alkenes: Direct Access to Planar Benzo[ a ]fluorenones

Abstract A rhodium-catalyzed [3 + 2] annulation of aromatic acids and 7-oxabenzonorbornadienes has been developed, enabling a facile one-step synthesis of planar π-conjugated polycyclic benzo[a]fluorenone featuring an ordered herringbone packing motif with slipped stacking in mod...

The state-led reproductive boundary: Divisions and income disparity in mainland China's paid care work

This study examines how the state and the market shape income divisions among paid care workers in China's domestic service economy. We develop the concept of the state-led reproductive boundary to examine how state intervention, through certification, training, work arrangement,...

CCA-ID: Confidence-calibrated adaptive intrusion detection with selective routing for IoT networks

The rapid expansion of Internet of Things (IoT) deployments has extended the cyber-attack surface. In resource-constrained IoT monitoring environments, maintaining always-on deep or ensemble-based intrusion detection can be challenging for high-rate, real-time traffic. This study...

Observed teacher collaboration indices: Professional learning impact, self‐efficacy and job satisfaction among lower and upper secondary teachers in TALIS 2024

Abstract Teacher collaboration is widely promoted as a resource for professional learning, teacher efficacy and retention, but research and policy often treat collaboration as a single practice and use frequency as a proxy for professional value. This risks overlooking difference...

Fungal extracellular vesicles reshape Lactobacillus rhamnosus vesicles to enhance lysosomal homeostasis and resolve intestinal inflammation

Extracellular vesicles (EVs) are emerging mediators of intercellular and interkingdom communication. While bacterial EVs directly modulate host health, whether exogenous vesicles can reprogram gut microbial vesiculation and bioactivity remains unclear. Using a defined in vitro co...

Global analyses of a state-dependent impulsive system for an SIRS model with a nonlinear incidence rate

, however, the model may exhibit bistability between the disease-free periodic solution and an endemic periodic solution, where the final outcome depends sensitively on the initial infection size, which is consistent with the weak transmissibility and controllable low-level preva...

A Cobalt Porphyrin Doubly Tethered with Piperazine Groups for Highly Selective Electrocatalytic Four‐Electron Oxygen Reduction Reaction in Acidic Aqueous Solution

Comprehensive Summary Selective electrocatalytic four‐electron (4e) oxygen reduction reaction (ORR) is required in many new energy conversion technologies. Although Co porphyrins are active for electrocatalytic ORR, their selectivity for the 4e ORR is usually poor. Herein, we rep...

Mechanism and Origins of Enantioselectivity of Rhodium‐Catalyzed [4+3] Annulation of Benzosilacyclobutenes with 7‐Oxabenzonorbornadienes

ABSTRACT Rhodium‐catalyzed asymmetric [4+3] annulation of benzosilacyclobutenes with 7‐oxabenzonorbornadienes provides an efficient route to enantioenriched seven‐membered sila‐heterocycles. In this study, density functional theory calculations were performed to elucidate the rea...

Age-related vertical soil water redistribution and root water uptake pattern of artificial forest in the Loess Plateau of China

Understanding how stand age regulates soil water balance components is essential for sustainable afforestation in semi-arid regions. However, the long-term dynamics of deep soil water depletion and root water uptake patterns at different forest growth stages remain insufficiently...

Practical synthesis of 3-Oxa/Aza-bicyclo[3.1.1]heptanes from 3-Oxa/Aza[3.1.1]propellanes

While bicyclo[1.1.1]pentanes (BCPs) and bicyclo[3.1.1]heptanes (BCHeps) serve as established 3D bioisosteres for para- and meta-substituted benzenes, accessible via ring-opening of their corresponding propellanes, the integration of heteroatoms into these propellane scaffolds has...

Inverse ZrO2/Co Enables Low-Temperature Direct CO2 Hydrogenation to Liquid Hydrocarbons

Abstract Direct hydrogenation of CO2 to liquid hydrocarbons (C5+) at low temperature is a highly desirable but challenging transformation, as conventional catalysts typically operate at high temperatures via indirect pathways by producing and using a CO intermediate. In this work...

A morphology‐based phylogeny of Gryllidae: Insights from a conspecific pair of mid‐Cretaceous amber crickets

Abstract Gryllidae Laicharting, 1781, the most speciose family within Grylloidea, has a rich fossil record; yet, the phylogenetic relationships among these fossil taxa remain poorly resolved. Integration of fossil and extant lineages into a systematic framework has been impeded b...
