Graphitic carbon nitride (g-C3N4) powders were successfully synthesized from ball-milled amorphous carbon under NHs atmosphere at high temperature, for the first time to the best of our knowledge. The combined characteristic data obtained by x-ray diffraction, high-resolution transmission-electron microscopy, electron energy loss spectroscopy, Raman spectroscopy, energy dispersive spectroscopic analysis, and Fourier transformation infrared spectroscopy provide substantial evidence for the graphite-like sp2-bonded structure with C3N4 stoichiometry.

早期准确地评估肿瘤患者的淋巴结及难以解释的淋巴结病变,对选择合适的治疗计划及预后的判断至关重要.目前,淋巴结大小仍然是区别转移性和非转移性淋巴结的最常用的指标,但是其准确性不高,为了提高对淋巴结良恶性病变评估的准确性,需要找到一种新的显像方法,它并不仅仅局限于对淋巴结解剖上的评估,还可以在细胞水平对淋巴结生理和生化过程进行直观和定量评估.不同的影像学方法在评价局部淋巴结时具有各自的特点,随着分子影
