Food Security Versus Environmental Health: The Nitrogen Dilemma

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Soil Type Controls the Effects of the Nitrification Inhibitor DMPP on Nitrate Leaching and Mineral N Retention Under Simulated Heavy Rainfall

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Nitrate (NO3−) leaching is a major nitrogen (N) loss pathway in agriculture and may increase with more frequent heavy rainfall. Nitrification inhibitors, such as 3,4‐dimethylpyrazole phosphate (DMPP), can reduce these losses, but their effectiveness under frequent heavy rainfall events remains unclear, which limits their targeted ...

Spatiotemporal distribution and potential functions of N2O-reducing bacteria in the waters of the Pearl River Estuary

BMC Microbiology
Background The reduction of N2O to N2, catalyzed by two kinds of N2O-reducing bacteria, is the only known biological pathway of N2O sink. However, the distribution and function of N2O-reducing bacteria in estuarine waters remains unknown.

Effects of Fertilization and Wheat Straw Management on Rice Yield and Greenhouse Gas Emissions in Paddy Fields

Land Degradation &Development, EarlyView.
ABSTRACT Environmental pollution caused by excessive nitrogen fertilization has become increasingly serious, making optimized fertilization and straw management critical for improving agricultural sustainability. This study involved a two‐year field trial with three fertilization strategies: conventional fertilization (CF), 23.50% nitrogen reduction ...

Optimized Fertilization Balances Microbial Carbon and Nitrogen Use Efficiency: Evidence From Microbial Communities

Land Degradation &Development, EarlyView.
ABSTRACT Optimized fertilization involving reduced mineral N input and organic substitution can alter resource stoichiometry, microbial carbon use efficiency (CUE) and nitrogen use efficiency (NUE). However, how fertilization‐induced resource imbalance reshapes microbial community to regulate CUE and NUE remains unclear. We conducted a field experiment

Nanoscale Rear‐Interface Architecture Enables 36.2 mA cm−2 Photocurrent in Ultrathin and Bifacial ACIGS Solar Cells Through Light Management

Laser &Photonics Reviews, EarlyView.
An array of SiOx nanopillars is developed on ITO transparent rear contacts through nanoimprint lithography to promote light scattering in 500–600 nm bifacial ACIGS solar cells. This architecture increases the short‐circuit current density by 7.8 and 7.6 mA cm−2 under front (up to 36.2 mA cm−2) and rear illumination, respectively, offering a scalable ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

A Voxel‐Wise T2 Distribution Framework for Lesion Severity Stratification and Treatment‐Response Assessment in Stroke: Insights Into Suberoylanilide Hydroxamic Acid‐Induced Neuroprotection

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate lesion severity distribution in ischaemic brain lesions in spontaneously hypertensive rats (SHR) subjected to 90‐min transient middle cerebral artery occlusion (tMCAO), and to determine whether epigenetically based neuroprotection modifies lesion severity profiles using a voxel‐wise T2 distribution framework.

Reducing Ammonia Emission during Food Waste Composting and Enhancing Compost Quality Using Different Additives

ChemistryOpen, EarlyView.
This research successfully reduces the ammonia emission by 45% and achieves good quality compost using additives (lactic acid or acetic acid) and bulking agents (mature compost or sawdust). The study supports Sustainable Development Goals 12 and 13 by promoting waste‐to‐resource option.
