Surface‐Mounted Metal‐Organic Framework for the Adsorption and Sensing of Monoaromatic Pollutants in Water Using Quartz Crystal Microbalance

Advanced Materials Technologies, EarlyView.
A hydrophobic metal‐organic framework (UHMOF‐100) is grown on a quartz crystal microbalance sensor for the first time. The device enables real‐time, selective detection of monoaromatic BTEX pollutants in water, demonstrating a new strategy for creating robust chemical sensors for challenging environmental monitoring applications. Abstract Environmental

Life Cycle Assessment of Magnesium‐Impregnated Biochar Production and its Application for Nutrient Removal and Soil Improvement in Rice Cultivation

Advanced Sustainable Systems, EarlyView.
This study evaluates the environmental trade‐offs of different rice husk management strategies using a life cycle assessment (LCA) approach. It compares biochar production for water treatment and soil improvement with direct incineration for energy generation.

Efficient Model Calibration Using Submodels

Water Resources Research
Groundwater models tend to become increasingly detailed to accommodate increasing data availability and higher accuracy demands from stakeholders. As runtimes increase almost quadratically with the number of model cells, this makes the models ever more ...

In Situ Structural Evolution and Activity Descriptor of Atomically Dispersed Catalysts During Nitrate Electroreduction

Advanced Science, EarlyView.
The in situ evolution of single‐atom catalysts to metallic nanoclusters during nitrate electroreduction is demonstrated. A direct correlation between the OH binding energy on the metallic clusters and ammonia production rate is established as a key activity descriptor, explaining the superior performance of Ni and Co catalysts.

Novel Role of Gut‐Derived Roseburia Intestinalis in Safeguarding Intestinal Barrier Integrity and Microenvironment Homeostasis During Arsenic Exposure

Advanced Science, EarlyView.
Arsenic exposure disrupts intestinal barriers and gut microenvironment. Fecal microbiota transplantation (FMT) alleviates arsenic‐induced damage, with gut‐derived Roseburia intestinalis (R.i) identified as a key protective strain. R.i administration counters arsenic toxicity through immunomodulatory pathways and metabolites.
