An oligothiophene derivative named DR3TBDTT with high hydrophobicity was synthesized and functioned as the hole transporting material without an ion additive. 8.8% of power conversion efficiency was obtained for CH3NH3PbI3-xClx based planar solar cells with improved stability, compared to devices using Li-TFSI doped spiro-MeOTAD.

Serum IL-6 levels correlated with disease status of colorectal cancer but could not be regarded as an independent predictor for prognosis.

This study confirms that LigaSure system can achieve a radical ablation of hemorrhoids, reduce operative time, and result in less postoperative pain on postoperative Days 1 and 2.
