High Free‐Volume Imidazole‐Based Ionomers for High‐Temperature Proton Exchange Membrane Fuel Cells
Advanced Science, EarlyView.High free‐volume imidazole‐based ionomers (PF4IM‐72) enable enhanced phosphoric acid uptake and efficient proton transport, delivering peak power densities of 0.645 W cm−2 at 160 °C and 0.838 W cm−2 at 200 °C in HT‐PEMFCs. This work highlights a promising platform for next‐generation ionomers with improved high‐temperature performance and stability ...

Advanced Science, EarlyView.Light wavelength encodes distinct macrophage fates through mitochondrial and metabolic remodeling. Red 625 nm irradiation induces glycolysis, mitochondrial fission, and M1 polarization, whereas near‐infrared 850 nm irradiation promotes fatty acid oxidation, mitochondrial fusion, and M2 polarization.

Tracking the efficacy of prescribed burns in three phases: fuel removal, wildfire mitigation, and vegetation recovery [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesIn the United States (U.S.), aggressive suppression policies in the 20th century reduced wildfires in the short term, but accumulated fuels contributed to increased wildfire risk in the long term.

Adipocyte Myoglobin Is a Determinant of Energy Expenditure and a Potential Target to Limit Obesity
Advanced Science, EarlyView.Myoglobin, known as a muscle oxygen‐carrying protein, is shown to play a key role in fat cells that burn energy. Loss of myoglobin reduces the body's ability to generate heat and increases obesity risk, while restoring it improves metabolism. The study identifies myoglobin as a regulator of fat burning and a potential target to enhance energy ...

Fire Season and fuel Load Predict Fire Behavior in Open Savannas in Northern Cerrado
Biodiversidade Brasileira, 2019 Fire is one of the main factors determining the structure of mesic savannas like the Brazilian Cerrado. Its plant species have evolved with fire for millions of years, but intense human use in the past century has been threatening biodiversity.

Advanced Science, EarlyView.ROS‐Responsive H2S Hydrogel (HAPPF) Coordinated Regeneration for High‐Quality Diabetic Wound Repair.A self‐regulating dynamic hydrogel is developed to deliver a fluorogenic H2S donor in response to excessive ROS. Released H2S acts as a master regulator to resolve chronic inflammation (M2 polarization), restore VEGF‐driven angiogenesis, and rebalance ...

Advanced Science, EarlyView.A nebulized nanoassembly alleviates radiation‐induced lung injury by reprogramming macrophages through coordinated ROS scavenging, NAD+ replenishment, and PPAR‐γ activation. Redox balance, mitochondrial homeostasis, and immune regulation are restored, revealing a microenvironment‐centered strategy for localized radioprotection.

Fuel Microstructural Analysis of Incubation Burn-Up for Fission Gas Release
Journal of Nuclear Science and Technology, 1986 A study was made on an incubation burn-up for fission gas release using fuel swelling microstructural analysis. Conclusions of the study are: (1) The fuel microstructural analysis successfully determined the incubation burn-up. The analyzed values agreed with those estimated by the Halden empirical gas release model. (2) The incubation burn-up obtained

Advanced Science, EarlyView.In bladder cancer, LRG1 binds to ANXA2 to trigger mitochondrial ROS‐dependent NETosis. This pathogenic cascade actively uncouples endothelial‐mural cell interactions, driving profound vascular destabilization. Consequently, targeting the LRG1‐ANXA2 axis attenuates the neutrophil burden and induces structural vascular normalization, offering a powerful ...
