Cationic High-Entropy Doping Endows O3-Type Na-Ni-Mn-O-Layered Cathode with High Energy Density and Sustainable Sodium Storage

Abstract Although O3-type layered oxides featuring an open framework demonstrate potential as high-capacity cathode materials for sodium-ion batteries, such cathode materials are confronted with commercial limitations, including intricate phase transition mechanisms, structural d...

Layered double hydroxides and metal–organic frameworks aided preparation of polymetallic sulfide electrode for efficient supercapacitor

Polymetal sulfides are regarded as highly promising electrode materials for supercapacitors (SCs), owing to their high stability, relatively short electron transport pathways, enhanced electronic conductivity, and favorable electrochemical properties. Notably, polymetal sulfides...

Informational teacher support strengthens the association between psychological resilience and academic self efficacy among preservice English teachers

Abstract In high-demand, high-stakes pre-service English teacher education, academic self-efficacy is critical for sustained engagement and performance in core tasks (e.g., microteaching, lesson planning, and classroom management). Yet evidence on how resilience translates into s...

Subjective well-being mediates and mindfulness moderates the relationship between perceived discrimination and altruistic behavior in college students with financial difficulties

Altruistic behavior is an essential positive psychological trait for college students. College students with financial difficulties are more likely to perceive discrimination, which may decrease their altruistic behavior, hindering personal growth and social stability. Our study...

An Integrated dual-mode NIR Screening Device Forged by Spectrally Engineered Perovskite pc-LEDs

Abstract Translating advanced luminescent materials into field-deployable screening tools remains a core challenge, demanding synergy between advanced optical materials and device engineering. Here, we demonstrate a portable dual-mode near-infrared semi-quantitative screening dev...

Facilitation or inhibition? The impact of IPR protection on the quality of corporate green innovation

High-quality green innovation is a key driver in promoting sustainable development and accelerating the green transformation of economic structures. Using the National Intellectual Property Model City program as a quasi-natural experiment, this paper examines the impact of intell...

The sword of damocles: AI partners and digital avatars in an era of elderly companionship collapse

Declining global fertility has produced a growing, often invisible population facing Elderly Companionship Collapse—older adults who are childless, kinless, sole family survivors, or aging solo. AI companions already simulate presence; Phase II avatars that digitally resurrect de...

Adaptive intrathecal nanorobotics in mice and nonhuman primates for navigated CNS therapy

Intrathecal delivery for central nervous system (CNS) therapy lacks spatiotemporal control due to spinal canal anatomical constraints, especially at human scale. We developed an adaptive magnetic nanorobotic platform enabling multimode swarm mobility for in vivo spinal canal navi...
