Dry–Hot Compound Events Driving the 2024 Pantanal Wildfires

International Journal of Climatology, EarlyView.
Extreme wildfires in the Pantanal in 2024 were driven by a cascade of heatwaves, rainfall deficits and the absence of the annual flood pulse. These conditions dried soils and rivers, enhanced fuel accumulation and enabled early and intense fire outbreaks.

Testing VIPV Curved Modules: Methods and Challenges

Progress in Photovoltaics: Research and Applications, EarlyView.
This work presents procedures and equipment for characterizing curved vehicle‐integrated photovoltaic (VIPV) modules through STC I–V curve and relative angular response (RAR) measurements. Outdoor measurements are compared with indoor measurements obtained using a collimated‐light solar simulator, showing excellent agreement for STC I–V curves.

Robotics‐assisted acoustic surveys could deliver reliable, landscape‐level biodiversity insights

Remote Sensing in Ecology and Conservation, EarlyView.
Deploying and maintaining sensors is often a major bottleneck in collecting rapid biodiversity data. We tested whether autonomous hopping drones equipped with acoustic recorders could collect reliable biodiversity data in Costa Rica. Using 26,000+ hours of existing audio from 341 sites, with machine learning detections of 19 bird species and spider ...

Mechanochemical Fullerene Nanoencapsulation in Amino‐Functionalized ZIF‐12 for Visible‐Light Disinfection of Waterborne Viruses and Bacteria

Small, EarlyView.
A solvent‐minimized mechanochemical strategy enables the synthesis of C₆₀‐encapsulated amino‐functionalized ZIF‐12 as a visible‐light‐driven bifunctional photocatalyst. Synergistic charge separation enhances hydroxyl radical generation, achieving efficient viral in saline water and bacterial inactivation in river water under environmentally relevant ...
