In situ growth of heterostructured Sn/SnO nanospheres embedded in crumpled graphene as an anode material for lithium ion batteries.

The in situ growth of Sn/SnO heterostructured nanospheres embedded in crumpled graphene is based on a new strategy for the calcination of tin oleate coating on the crystal surface of sodium carbonate. Sn/SnO nanospheres and crumpled graphene are acquired simultaneously without external forces involved. The obtained composite exhibits superior electrochemical properties when used as an anode material for lithium-ion batteries.

Uniportal video-assisted thoracoscopic combined segmentectomy for lung cancer with incomplete fissure.

This video clip demonstrated a performance of uniportal video-assisted thoracoscopic surgery combined segmentectomy. The patient had a potential invasive nodule located near the bifurcation of right bronchus, 3-dimensional reconstruction image showed the fissure between posterior segment of upper lobe and superior segment of lower lobe was incomplete. An up-to-down approach was applied in this operation with the en bloc resection of the two segments.

Primary tracheal schwannoma treated by surgical resection: a case report.

The rarity and non-specific symptoms of benign primary tracheal tumors always leaded to misdiagnosis and delayed treatment, and also undefined the optimal treatment. In this case, a 45-year-old woman had a history of progressive shortness of breath and dry cough for several years, CT scan revealed an intra-luminal tracheal mass invaded the left side of tracheal wall. After being located by bronchoscope preoperatively, the tumor was removed by surgical resection.
