Highly Selective Electrocatalytic Ammonia Synthesis Enabled by Spatial Separation of Active Hydrogen Capture and Spillover Sites

ABSTRACT Electrochemical nitrate reduction (eNO 3 RR) enables sustainable ammonia (NH 3 ) synthesis and nitrate (NO 3 − ) remediation but is limited by sluggish multi‐step proton−electron transfers and inefficient intermediate conversion. To address these challenges, we strategic...

Hierarchical Fuzzy Adaptive Control for Cooperative Pursuit‐Evasion Formation in Marine Surface Vehicles

ABSTRACT This paper investigates a formation‐based cooperative pursuit‐evasion (PE) problem for marine surface vehicles (MSVs) under local sensing and partially connected communication topologies. A distributed two‐layer control framework is proposed for the case where each pursu...

Wavelength- and Energy-Dependent Nonlinear Absorption and Transient Absorption in Silver Nanoparticles

Nonlinear absorption (NLA) in silver nanoparticles (Ag NPs) is strongly affected by plasmonic field enhancement. However, its wavelength- and energy-dependent evolution on the red side of the surface plasmon resonance (SPR) band remains insufficiently understood. Here, we systema...

CLM-YOLO: An Improved YOLOv11n-Based Model for Accurate Rice Pest Detection and Intelligent Monitoring

Rice is one of the most important food crops in China, and frequent outbreaks of rice pests pose a serious threat to both the yield and quality of rice. Accurate monitoring of rice pests is therefore of great significance for field management and intelligent pest control. In this...

Genome-wide identification of the chalcone synthase (CHS) family in tigernut and function analysis of cechs57 in drought stress response

Drought stress is a major abiotic constraint that severely impairs crop growth and reduces yield globally. Identification of drought-tolerant candidate genes and their application in molecular breeding represent effective strategies to alleviate drought-induced losses. Genome-wid...
