Polymer Engineering &Science, EarlyView.A hydrodynamic process window for roll‐to‐roll slot‐die coating of photosensitive solder resist (PSR) was established by systematically varying the slot‐die gap and pump flow rate. Under the optimized conditions, a highly uniform 26 μm dry‐film solder resist (DFSR) layer with a thickness variation of ±3.74% was obtained without coating defects.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

PLANTS, PEOPLE, PLANET, EarlyView.Earth's ecosystems are experiencing wide‐ranging impacts from global climate change, including increased average and extreme temperatures. These temperature shifts can drastically affect plant physiology, threatening the future of even common plant species. Here, we focus on photosynthetic function in a native Southern California shrub species.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers
River Research and Applications, EarlyView.ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Large‐Scale MXene Membrane Fabrication via Nonsolvent Phase Separation
Small Methods, EarlyView.ABSTRACT Over the past decade, 2D MXenes have garnered tremendous attention for membrane applications owing to their exceptional hydrophilicity, tunable surface chemistry, and antifouling properties. However, translating MXene‐based membranes from laboratory demonstrations to practically relevant manufacturing remains challenging because scalable ...
