Spatiotemporal-switchable 2D NIR-II single-atom nanozyme for single-cell–level surgical navigation and glioblastoma phototherapy

Single-cell–level resolution tumor therapy represents an advanced strategy against glioblastoma but lacks suitable theranostic agents. Here, we developed a spatiotemporal-switchable, two-dimensional (2D), bismuthene-based second near-infrared window (NIR-II) nanozyme. In this pla...

Review of Particle Physics *

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,200 new measurements from 903 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and b...

Beyond Morphological Conservatism: Integrative Taxonomy Unveils Remarkable Cryptic Diversity in the Tachysurus virgatus (Oshima 1926) Group (Siluriformes: Bagridae) Endemic to the Northern Margin of East Asian Tropics

The northern margin of the East Asian tropics harbors exceptional endemism, yet its freshwater fish fauna remains poorly characterized. Tachysurus virgatus, long considered a single widespread species in this region, exemplifies this taxonomic gap. Through integrative taxonomic a...

Antioxidant nanozymes for regenerative medicine: mechanisms, design, and applications in tissue repair

Natural antioxidant enzymes play a central role in regulating oxidative stress within living organisms. During tissue repair following injury, these enzymes act synergistically to scavenge excess reactive oxygen species and maintain cellular redox homeostasis, thereby supporting...

Thermally Modulated Microfluidic Fabrication of Phase-Tunable Cs4PbBr6/CsPbBr3 Hybrid Perovskite Nanocrystals for White Light-Emitting Diodes

All inorganic CsPbBr3 perovskite nanocrystals (NCs) exhibit outstanding luminescence for optoelectronics, yet poor environmental stability severely restricts their practical deployment. As a stable derivative phase, Cs4PbBr6 can effectively improve structural stability. Neverthel...

Abstract Direct C–H bond functionalization represents a facile synthetic strategy that adheres to the principle of atom economy. Among a variety of metal catalysts, rhodium catalysts demonstrate distinctive advantages owing to their excellent reactivity. This account summarizes o...

From Spatial Evolution to Low-Carbon Transition: Regional Heterogeneity and Stage Diagnosis of Carbon Emissions Across 19 Urban Agglomerations in China

Understanding the spatiotemporal dynamics of carbon emissions and developing differentiated governance strategies for urban agglomerations are essential for achieving regional low-carbon transformation. This study aims to identify the spatiotemporal patterns, driving mechanisms,...

Trichoderma-Enabled Crop Resilience Under Abiotic Stress: From Field Delivery to Systems-Level Stress Reprogramming

Abiotic stresses increasingly threaten crop productivity, whereas reliance on chemical and resource-intensive interventions can compromise environmental sustainability. Existing literature identifies Trichoderma spp. as multifunctional biocontrol agents, biofertilizers, and micro...

Trends and Lagged Cumulative Associations Between Vegetation NDVI and Extreme Climate Indices in the Yangtze River Basin: A 41-Year Observational Analysis

Extreme climate events can disturb vegetation dynamics and alter ecosystem stability. This study investigated the evolution of extreme climatic conditions and vegetation greenness across the Yangtze River Basin during 1982–2022 by integrating CN05.1 daily meteorological records w...

A Microseismic Energy Field Distribution Prediction Method Guided by Geological Structure Priors

Existing microseismic prediction methods commonly incorporate domain prior knowledge as ordinary input features, which makes it difficult to fully exploit its structural constraints and physical implications. To address this limitation, this study proposes a geological-structure-...
