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

野生动物学报, 2011 精液品质评定的常见方法有精子活力、畸形率和顶体完整率等指标,但这些指标不能评定精子的真实受精能力。目前低渗膨胀试验作为检验精子膜功能的一种方法得到广泛认可,利用它可检验具有完整膜的精子是否具有生化活性。本试验通过对冷冻2只黑猩猩精液进行低渗膨胀来评定冷冻精子的膜完整性。试验结果显示,本研究中的黑猩猩的冷冻精子在低渗溶液中的膨胀率较高,表明试验黑猩猩的冷冻精液有较高的活力,精子具有较高的穿透率和受精能力。

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT NiFe‐based MIL‐55 metal‐organic frameworks (MOFs) face challenges in achieving atomically precise composition and reliable methods for uniform growth. This study addresses these challenges by applying a slow evaporation crystallization technique to crude colloidal MIL‐55 products from hydrothermal synthesis, resulting in highly uniform ...

Shp2 in Sertoli cells Regulate Spermatogenesis [PDF]
, 2015 支持细胞（sertolicell）为各级生精细胞提供营养、支持、保护作用，分泌一些对精子发生有重要作用的成分，参与FSH、睾酮对生殖细胞的的调节作用。 Shp2是一种细胞质中的蛋白酪氨酸磷酸酶，弥散性表达于全身各器官，调控多种生长因子的信号，调节细胞增殖和分化、参与免疫反应、调控代谢。研究支持细胞当中的Shp2对精子发生的调控具有理论意义和实用价值。虽然在努男综合症（noonan）中涉及过Shp2与雄性生殖的关系，以及大鼠睾丸支持细胞中Shp2介导肝细胞生长因子（HGF）的Ras-MAPK信号通路 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The development of efficient and stable bifunctional electrocatalysts is a key challenge for the industrialization of hydrogen production by water electrolysis. In this work, Co‐doped NiS/Ni3S2 heterostructured nanowire arrays (Co–NiS/Ni3S2 NA) were successfully constructed by precisely modulating the phase‐selective behavior of nickel ...

Studies on Biology of Early Developmental Stages of Babylonia [PDF]
, 2016 东风螺(Babylonia)隶属软体动物门(Mollusca)、腹足纲(Gastropoda)、新腹足目(Neogastropoda)、东风螺科(Babyloniidae)，分布于中国东海、南海以及东南亚、日本和印度洋沿岸，因肉质鲜美、市场接受度高，而且生长速度快、养殖产量大，被认为是本世纪最具开发前景的优质海产腹足类之一。方斑东风螺和泥东风螺是我国常见的东风螺种类，对于其早期发育阶段的形态学以及多种组学进行研究，不仅在理论研究上具有科学意义，而且在生产实践上也具有重要的指导意义 ...

People and Nature, Volume 8, Issue 2, Page 270-282, February 2026.Abstract Chinese consumer demand for ivory threatens vulnerable African elephant populations, despite long‐standing efforts to combat the illegal wildlife trade. Behavioural science approaches have been proposed to address these systemic behaviours. However, their robust use remains uncommon in demand management interventions.
