A Hybrid Material Combined Copper Oxide with Graphene for an Oxygen Reduction Reaction in an Alkaline Medium.

ABSTRACT: In this work, an electrode material based on CuO nanoparticles (NPs)/graphene (G) is developed for ORR in alkaline medium. According to the characterization of scanning electron microscope and transmission electron microscope, CuO NPs are uniformly distributed on the wrinkled G sheets. The X-ray diffraction test reveals that the phase of CuO is monoclinic. The CuO/G hybrid electrode exhibits a positive onset potential (0.8 V), high cathodic current density (3.79 × 10-5 mA/cm²) and high electron transfer number (four-electron from O? to H?O) for ORR in alkaline media. Compared with commercial Pt/C electrocatalyst, the CuO/G electrode also shows superior fuel durability. The high electrocatalytic activity and durability are attribute to the strong coupling between CuO NPs and G nanosheets.

We report two octogenarian patients with primary urethral cancer treated with chemotherapy and external beam radiation therapy. An 85-year-old female presented with perineal bleeding. Magnetic resonance imaging (MRI) showed a locally advanced tumor in the urethra. Biopsy was performed and pathologic findings demonstrated squamous cell carcinoma. After receiving one cycle of a half dose of gemcitabine and nedaplatin, the patient received external beam radiation therapy with gemcitabine and nedapl  ...[more]
