Enabling fast ionic transport in CeO-LaBaBiFeO nanocomposite electrolyte for low temperature solid oxide fuel cell application.

Recent studies indicate that electrolyte ionic conductivity plays a pivotal role in reducing the operating temperature of solid oxide fuel cells (SOFCs). In this regard, nanocomposite electrolytes have drawn significant attention owing to their enhanced ionic conductivity and fast ionic transport. In this study, we fabricated CeO-LaBaBiFeO nanocomposites and tested them as a high-performance electrolyte for low-temperature solid oxide fuel cells (LT-SOFCs).

[Metabolism of mangiferin by human intestinal bacteria in vitro].

Objective: To study the metabolism of mangiferin by human intestinal bacteria in vitro.

Method: Human intestinal bacteria and mangiferin were incubated under anaerobic conditions in vitro. The metabolite was separated and purified by D101 macroporous resin column and preparation high performance liquid chromatography, and its structure was identified by MS and NMR.

[Optimization of molding technics of xiaochuang granules by central composite design-response surface methodology].

Objective: The optimal molding technics of Xiaochuang granules was selected.

Methods: The main influential factors of the molding technics included the mixed excipients' ratio, the quantity times of excipients and the ethanol concentration. The molding effect was evaluated with the yield of qualified granules and solubility.
