Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The precise quantification of cytokines is crucial for monitoring disease onset and progression. Herein, we developed a synergistic signal amplification approach by utilizing nanoreactor‐encapsulated CeO2 nanozymes, which were in situ electrodeposited within the mesoporous silica nanochannel film (SNF) grown on indium tin oxide (ITO ...

Gaoya dianqi, 2022 电力设备局部放电射频检测技术具有灵敏度高、抗干扰能力强的优势。该方法在电力设备带电检测中得到了广泛重视和推广应用。然而，电力设备的金属外壳限制了射频信号向外传播，极大降低了外置式射频检测技术的灵敏度。为此，提出一种地线外置式局部放电射频检测方法。首先，阐述了地线引出电力设备金属外壳的结构，阐述了局部放电射频信号在地线上耦合、传导、辐射的原理；其次，利用时域有限差分法仿真了射频电磁波经过地线向外传播的动态过程，分析了设备外侧射频信号的时频特性；最后，应用了地线外置式射频信号检测方法 ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...
