    Synthesis, Magnetization, and Electrical Transport Properties of Mn3Zn0.9Cu0.1N by Y. Yin, J. C. Han, T. P. Ying, J. K. Jian, Z. H. Zhang, L. S. Ling, L. Pi, B. Song

    Published 2013-01-01
    “…It is found that Mn3Zn0.9Cu0.1N exhibits a first-order antiferromagnetism (AFM) to paramagnetic (PM) transition with the Néel temperature TN ~163 K, and substitution of Cu for Zn would favor ferromagnetism (FM) state and weaken AFM ground state, leading to a convex curvature character of M(T) curve. With high external fields 10 kOe–50 kOe, magnetic transition remains a robust AFM-PM feature while FM phase is completely suppressed. …”

    Published 2025-01-01
    “…Ethylene signaling appears to be involved in the regulation of these processes, as treatment with a competitive inhibitor of ethylene action, 1‐methylcyclopropene, delayed vesiculation, reduced the expression of SAG12, and increased expression of Curvature Thylakoid 1A (CURT1A). In addition, chloroplast vesiculation during abscission was associated with differential expression of photosynthesis‐related genes, particularly those involved in light reactions, underscoring the possible functional impact of the observed structural changes. …”
