Sensing oxysulfates: A new type of bismuth oxysulfate nanowire emerges from the straightforward hydrothermal reaction of Bi2O3 and K2SO4. The formation pathway of this versatile material is monitored with in situ QEXAFS techniques. The high-aspect-ratio nanorods display promising features for application in humidity sensors.
