Tumor metastasis remains the primary cause of treatment failure in cancer patients, and high-sensitivity preoperative intraoperative detection occult micrometastases continues to pose a notorious challenge. Therefore, we have designed an situ albumin-hitchhiking near-infrared window II (NIR-II) fluorescence probe, IR1080, for precise subsequent image-guided surgery. IR1080 rapidly covalently conjugates with albumin plasma, resulting stronger brightness upon binding. Moreover,...

The research on snubber circuits for power electronic switch (PE switch) in DC current breaking is introduced this paper. During the turn-off of PE switch, voltage devices rises quickly due to high di/dt and system inductance. MOV connected parallel with absorb fault energy suppress overvoltage. However, across would surpass nominal because stray inductance existed loop MOV. J.Magnusson proposed a method without by use varistors. By analyzing transient shock during turn-off, it concluded...
