Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The realization of bifunctional perovskite devices integrating photovoltaic (PV) and light‐emitting diode (LED) capabilities requires precisely controlled grain architectures to facilitate dual carrier transport pathways. In this work, sulfaguanidine (SG) molecules were introduced into the perovskite solution to reconstruct the crystallization

Shuitu Baochi Xuebao, 2008 通过对比分析坡面水流的水动力参数与径流溶质迁移量间的关系,研究了不同地表状况下黄土坡面土壤溶质随径流迁移的水动力学特性,以求深入了解和认识坡面土壤侵蚀中溶质随径流迁移的本质机理。研究结果表明:不同坡面地表状况下,糙率系数和平均水深之比(n/h)与侵蚀过程中随径流迁移的溶质存在一定的关系,径流溶质Br-平均浓度、径流溶质Br-的平均流失率以及径流溶质Br-的相对流失量均随n/h的增加而减小。径流溶质Br-的平均流失率以及径流溶质Br-的相对流失量与水流水动力学参数n/h具有指数关系。
