Measurement report: Soil reactive nitrogen gas emissions in the Tibetan Plateau

Abstract. The Tibetan Plateau, highly sensitive to climate change, exerts strong atmospheric oxidation capacity partly through rapid cycling of atmospheric reactive nitrogen (Nr). Soil Nr emissions play a crucial role in atmospheric nitrogen cycling and oxidation capacity, yet th...

Reversible Inhibition of Ammonia Monooxygenase by 1,9-Decanediol Triggers a RegB-RegA-Associated Energy Crisis and Stress Response in Nitrosomonas europaea

Abstract 1,9-decanediol, a rice-derived biological nitrification inhibitor (BNI) suppresses soil nitrification and nitrous-oxide emissions, but the mechanisms of action against ammonia-oxidizing bacteria remain unclear. Combining physiology and transcriptomics in Nitrosomonas eur...

CropStabDB: a protein stability resource and Engineering Atlas of orthologue-supported substitutions for 30 plant proteomes

Protein stability, the capacity to maintain a folded structure and function, matters as much for transporters and regulators as for enzymes, and heat erodes it. Wheat, rice, maize and soybean supply two-thirds of human caloric intake, and warming reduces yields. Rubisco activase...

Physics-informed neural network for modeling coupled fluid flow and heat transport in a geothermal doublet system

Geothermal energy is an important renewable energy resource, and geothermal doublet systems are widely used for its sustainable exploitation. Accurate simulation of coupled fluid-flow and heat-transfer processes in geothermal doublet systems provides an important basis for assess...

Trophic reorganization may contribute to shifts in nitrogen transformations following alleviation of saline alkaline stress

Soil salinization is a widespread form of land degradation, yet how saline-alkaline stress is linked to belowground micro-food webs and shapes nitrogen transformations remains poorly understood. Here we compare natural saline–sodic and reclaimed farmland soils in northeastern Chi...

Temperature-dependent inhibition of methane oxidation by ammonium in paddy soils

Rice paddy soils are major sources of atmospheric methane emissions, contributing significantly to global warming. Methane oxidation by microbes regulates methane release from soils, but the process is influenced by temperature and nitrogen status. However, the interactive effect...

Short-Range Mass Transfer in Core–Shell Catalysts Suppresses Radical Self-Quenching for Efficient Water Purification

Abstract Fenton-like reactions hold considerable promise for organic wastewater treatment. However, their practical application remains limited by the difficulty of synthesizing the catalyst’s local structure in a controlled manner through a sustainable route. Herein, a coordinat...

Trace Element Bioavailability Shapes Bacterial Communities and Biological Nitrogen Fixation in Paddy Soils

Biological nitrogen fixation (BNF) is a key nitrogen source in paddy soils, yet its spatial variability remains poorly understood. In this study, we conducted a 90-day 15N2 labeling experiment using soils from seven paddy fields in Zhejiang Province, China, to quantify total nitr...

From FAT to value: building competence through fairness, accountability and transparency for sustainable business

Purpose The aim of this paper is to investigate how core characteristics of artificial intelligence (AI), including fairness, accountability and transparency (FAT), contribute to sustainable business value creation. Design/methodology/approach The data were collected through a su...

Nanoparticle-mediated drought resilience in cereal crops from physiological modulation to sustainable agronomic translation

Nanotechnology offers transformative potential for mitigating drought stress in cereal crops, yet translation from controlled environments to field applications remains constrained by inconsistent outcomes, limited mechanistic understanding, and insufficient environmental risk as...

Application and prospect of artificial intelligence in biochar for acidic soil amelioration

Abstract Effective amelioration of acidic soils with biochar is critical for mitigating soil degradation and promoting sustainable agriculture, yet this requires robust mechanistic understanding and predictive modeling. This review synthesizes the key biogeochemical pathways by w...

Impact of PGPR-enriched tuff on biochemical characteristics, antioxidant enzyme activities and hormonal responses in walnut saplings

Walnut (Juglans regia L.) is one of the most economically important tree nuts worldwide due to its nutritional and health-promoting properties. The use of plant growth-promoting rhizobacteria (PGPR) in agriculture is increasing attention as a sustainable alternative to intensivel...

Modulating the Spin State of Co 3+ to Promote Ampere‐Level Electrosynthesis of Ammonia

ABSTRACT Ammonia electrosynthesis via nitrate reduction offers a sustainable alternative to Haber–Bosch process, and this reaction involves an initial deoxygenation step from NO 3 − to *NO 2 , followed by successive hydrogenation steps to NH 3 . Previous studies have mainly focus...

The Melatonin–Nitric Oxide Signaling Pathway Alleviates Iron Starvation by Mobilizing Apoplastic Iron Pools and Reshaping Iron Transport in Rice ( Oryza sativa L.)

Iron (Fe) is indispensable for plant growth and development. Notably, melatonin (MT) serves as a key regulator to improve plant tolerance under nutrient stress conditions. Currently, the exact mechanism regulating MT's involvement in the rice Fe-deficiency response remains to be...
