Seeking organic cathode materials with low cost and long cycle life that can be employed for large‐scale energy storage remains a significant challenge. This work has synthesized an organic compound, triphenazino[2,3‐b](1,4,5,8,9,12‐hexaazatriphenylene) (TPHATP), with as high as 87.16% yield. This compound has a highly π‐conjugated and rigid molecular structure, which is synthesized by capping hexaketocyclohexane...
The combination of observation of skin lesion and digital image technology contributes to the diagnosis and treatment of skin diseases. To solve the problems of large variation of target size and shape in skin disease images, small difference between disease images and normal images, and difficulty of label acquisition, we propose a classification algorithm for skin lesion based on hybrid self‐supervised...
