In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Ceramic capacitors are critical components in advanced electronic devices, primarily due to their multi‐functionalities in energy/information storage and conversion. However, poor temperature stability remains a long‐standing challenge for practical applications, especially at extremely high‐ or low‐temperature conditions (e.g., > 200°C or ...

He jishu超声分子束注入是磁约束聚变装置常用的补充加料手段之一，并对等离子体流和湍流产生重要影响。实验在J-TEXT装置上开展，采用三台阶朗缪尔探针阵列，在欧姆放电氢等离子体中观测了超声分子束注入对边缘流和湍流的影响。结果表明：超声分子束注入后测地声模带状流、湍流及其驱动的粒子输运分别减小40%~60%、50%~70%及60%~70%，且伴随着离子-离子碰撞频率增大；湍流雷诺协强及湍流对测地声模带状流做功明显减小；密度及温度梯度降低。进一步分析表明，测地声模带状流减弱主要归因于湍流雷诺功的降低和碰撞率的增加 ...

He jishu电子回旋共振（Electron Cyclotron Resonance，ECR）预电离对于球形托卡马克的可靠启动有着重要意义。本文建立了球形托卡马克装置的三维模型，采用了多物理场仿真软件COMSOL对该装置内ECR的预电离过程进行了模拟，并在此基础上研究了不同输入功率对功率沉积、电子温度及电子密度的影响效应。研究结果表明，提高输入功率可以大大缩短电子的电离时间，使等离子体电子密度和电子温度的峰值均有较大的提升。但是，过高的输入功率也会使电离产生的等离子体密度过大，入射电磁波难以到达共振区位置 ...

Gaoya dianqi, 2016 表面介质阻挡放电因能产生大面积均匀等离子体而被广泛研究及应用。然而多数研究致力于通过改变反应器对放电产生的等离子体参数进行优化。文中重点研究了介质表面粗糙度对沿面介质阻挡放电特性的影响,从介质表面态角度对产生的等离子体进行优化。石英玻璃作为阻挡介质在实验前经均匀机械研磨,并测量处理后的介质表面粗糙度指标Ra。实验结果发现:当放电产生的低温等离子体均匀分布于放电气隙时,表面粗糙度指标Ra为427.1 nm的介质的起始放电电压最低、平均放电功率最大、放电产生等离子体的电子激发温度最高 ...
