Fig. 1: Structure characterization and structure–activity relationship between atomic strain and spin polarization.

From: Spin polarization induced by atomic strain of MBene promotes the ·O2– production for groundwater disinfection

Fig. 1

a AC-STEM and GPA images of MB with different HF etching times (18–21 h). Ɛxx is the strain along the horizontal axis. b The EPR  of MB-18/19/20/21. c Structure–activity relationship among Mo vacancy, tensile strain, and spin polarization. All error bars represent the standard deviation of three independent measurements. d HRTEM image of IS/MB-20. e Magnetic hysteresis loop of IS and IS/MB-20. f and g HRTEM images of areas 1 and 2, and corresponding strain mapping images based on GPA. The inset image in Fig. 1f is the SAED image of MB-20.
