Ablation mechanisms of bulk Nb4AlC3 ceramics at 1600–2200 °C in nitrogen plasma flame
Published 2025-03-01“…This paper systematically investigates the ablation behaviors of Nb4AlC3 ceramics in nitrogen plasma flames at 1600–2200 °C. By analyzing changes in ablation rate, microstructure, and elemental composition of the surface and cross-section, the ablation evolution mechanism of Nb4AlC3 ceramics is elucidated. …”

Potassium Sulfate Supplementation with Elevated Electrical Conductivity Was Unproductive for Hydroponic Strawberry at the Original Yamazaki Nutrient Solution Nitrogen Level
Published 2025-01-01“…Bare-root plants of strawberry ‘Monterey’ and ‘San Andreas’ were planted in a deep water culture hydroponic system and grown with initial K concentrations of 117, 194, 271, and 348 mg·L−1 under the same initial nitrogen concentration of 77 mg·L−1. As the K concentration increased from 117 to 348 mg·L−1, the nutrient solution electrical conductivity increased from 1.0 to 1.9 dS·m−1. …”
