Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In electrocatalysis, traditional single‐atom catalysts (SACs) face challenges in achieving coordinated control of reaction pathways due to limitations such as single local energy levels and carrier recombination. By introducing an additional defect structure, it is possible to break the electronic structure symmetry, thereby activating SACs ...

Shiyou jixie, 2011 针对输气干线优化设计属于约束非线性混合离散变量优化设计问题，采用以并行计算为基础的连续型Hopfield神经网络进行求解，将实际问题的优化解与神经网络的稳定状态相对应，把实际问题的优化过程映射为神经网络系统的演化过程。结果表明，CHNN算法能显著减小计算量，降低求解模型的计算复杂度，其优化效果优于模拟退火算法和方案比较法，可在保证各项约束的前提下，达到投资最小化，对输气干线优化设计和设计方案的优选具有一定的工程指导意义。

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In conventional photoconductive detectors, the shared collection path for dark current and photocurrent imposes a fundamental compromise between noise suppression and signal responsivity. To break this trade‐off, we introduce a device architecture featuring a strategically integrated third electrode within a MAPbI3/Nb2CTx heterostructure. This
