Unmasking the Electrochemiluminescence Properties of Ternary Mn/Fe/Co Metals Doped Porous g-CN Fiber-like Nanostructure.

Graphitic-phase carbon nitride (g-CN) materials have exhibited increasingly remarkable performance as emerging electrochemiluminescence (ECL) emitters, owing to their unique optical and electronic properties; however, the ECL merits of porous g-CN nanofibers doped with ternary metals are not yet explored. Deciphering the ECL properties of trimetal-doped g-CN nanofibers could provide an exquisite pathway for ultrasensitive sensing and imaging with impressive advantages of minimal background signal, great sensitivity, and durability. Herein, we rationally synthesized g-CN nanofibers doped atomically with Mn, Fe, and Co elements (Mn/Fe/Co/g-CN) in a one-pot via the protonation in ethanol and annealing process driven by the rolling up mechanism.

Xanthogranulomatous cholecystitis on fusion of the planes of the liver.

Xanthogranulomatous cholecystitis (CXG) is a rare entity of cholecystitis, characterized by the presence of xanthogranulomas within the gallbladder wall, that could be misdiagnosed as a vesicular carcinoma.
