Perfluoroarene‐Based Tin Halide Perovskite Photovoltaics

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Herein, perfluoroarene cations, 2‐(perfluorophenyl)methylammonium (F‐BNA) and 1,4‐(perfluorophenyl)dimethylammonium (F‐PDMA), are applied to form layered Ruddlesden–Popper and Dion–Jacobson tin‐based perovskites. Following a detailed structural and optoelectronic characterization, a suitable solvent is identified and the perfluoroarenes are applied to ...

Biosynthesis of phytases and phosphatases by Aspergillus niger 551

open access: yesAFRICAN JOURNAL OF BIOTECHNOLOGY, 2012
The purpose of this study was to determine the ability of the Aspergillus niger 551 strain to produce phytases and phosphatases in 24 days shake cultures at a pH adjusted to 5.5 and a changing (uncontrolled) pH, in a medium containing 0.5% of glucose and 4% of starch. The fermentation process of the culture performed with no adjustment of the pH showed
