Quantitative assessment of tree responses to the local environment can help provide scientific guidance for planted forest management. However, research on the climate-growth relationship of Korshinsk peashrub ( Caragana korshinskii Kom.) under different land preparation and post-management (irrigation) conditions is still insufficient. In this study, we collected 223 tree-ring samples from Korshinsk peashrubs using dendroecological methods and systematically quantified the relationships between shrub growth and c…

Abstract In this work, a new kind of YGdBa 4 CuNbO y (YGdNb-11411) nano-particles was designed and sintered using a solid-state reaction method, whereas their impact on the performance of GdBCO bulks was investigated for the first time. From the acquired x-ray diffraction data and scanning electron microscopy imaging results, it was proved that the YGdNb-11411 particles were of excellent chemical stability and did not react with other phases during the crystal growth process. The YGdNb-11411 particles ranged from …

In this study, the effect of the pre-infiltration temperature (Ti) on the liquid-phase infiltration characteristics and its effect on the magnetic properties of single-domain GdBCO bulks prepared by the top-seeded infiltration growth (TSIG) method are comprehensively investigated. The results reveal that (1) the liquid Ba-Cu-O phase (LP) did not uniformly infiltrate into the Gd2BaCuO5 (Gd-211) solid-phase pellet (SPP). (2) The initial melting and infiltration of the LP occurred at approximately 920 °C. The average…

During the preparation of single-domain (S-D) REBa2Cu3O7-x (RE-123) superconducting bulks, the seed crystals can serve as templates for crystal growth, guiding the newly formed crystals to grow in a specific direction, thereby ensuring the consistency of the crystal orientation within the sample. However, the infiltration temperature is typically restricted to approximately 1050 °C when employing NdBa2Cu3O7-x (Nd-123) crystal seeds in the traditional top-seeded infiltration growth (TSIG) technique for producing si…

To study the influence of thickness on the magnetic properties of ReBCO (Re = Y, Gd, Sm, Nd, etc.) bulk superconductors, a single domain gadolinium barium copper oxide (GdBCO) bulk superconductor fabricated by the Re + 011 top seeded infiltration growth (Re + 011 TSIG) method was continuously sliced along the bottom to obtain samples of different thickness. The levitation force and attractive force of these samples were tested at 77 K in the zero-field-cooled (ZFC) state. It is found that as the sample thickness d…
