After preparation, the films prepared with O+2 ions consisted of hematite (α-Fe2O3), although with a low degree of order as revealed by grazing angle X-ray diffraction (GXRD), transmission infrared (IR) spectroscopy and extended X-ray absorption fine structure (EXAFS) spectroscopy.
The foot-stepping angle and the BBB score are parameters assessing plantar stepping ability [21], [28], [53], requiring a low degree of supraspinal control.
