Tectochrysin is one of the major flavonoids of Alpinia oxyphylla Miquel. However, the anti-cancer effects and the molecular mechanisms of tectochrysin in colon cancer cells(More)
A novel in situ co-assembled nanocomposite LSM-Bi1.6 Er0.4 O3 (ESB) (icn-LSMESB) was obtained by conjugated wet-chemical synthesis. It showed an enhancement of the cathode polarization at 600 °C by >140 times relative to conventional LSM-Y0.08 Zr0.84 O1.92 (YSZ) cathodes and exceptional solid oxide fuel cell (SOFC) performance of >2 W cm(-2) below 750 °C.(More)
