Intermetallic compounds of the Cr–Mn system investigated using in situ powder neutron diffraction: The reported order-disorder transformation of the σ phase elucidated

Metal nitrides for seawater electrolysis

“…185 However, since the scattering coefficients of N and O atoms are so close that X-ray techniques cannot accurately distinguish between them, neutron diffraction techniques are required. 186 Although this method has been demonstrated, few studies have provided specific numerical values for the N content of MNs, possibly due to stringent sample crystallinity and size requirements. Recently, Li and colleagues employed a two-step method involving acid digestion and HPLC/UV-vis (Ultraviolet-visible) analysis to quantify the N content in commercial metal-based nitride reduction catalysts (Bi 2 O 3 and Fe).…”
