A case series of malignant pericardial effusion.

The most common primary malignancies that affect the pericardium are lung cancers. Typically, pericardial involvement stays undiagnosed, with almost 1-20% of all tumor-related autopsies revealing invasion of the pericardium. Pericardial effusions are seldom the first location of metastasis and presentation of a primary malignancy.

Rapid microwave hydrothermal processed spinel CoOnanospheres infused N-doped graphene nanosheets for high-performance battery.

Spinel CoOnanospheres have been synthesized by the microwave-assisted hydrothermal method. The N-doped graphene nanosheets (NGN) were synthesized using Hummer's method. The prepared spinel CoOand NGN were mixed under certain proportions using an ultrasonication process and treated with microwave radiation to prepare a novel spinel CoOnanospheres infused NGN.
