to fragment. That leads to surface corrosion and reduces the battery lifetime. Experiments made on D1B followed changes during cycling on different electrode materials. These experiments showed that a ... intermediate γ phase with a cell volume between that of the α and β phases may appear (see figure 1) for some peculiar alloy compositions. The ...

Why can’t alkaline batteries be recharged? D1B is a high intensity powder diffractometer with an 80° PSD (position sensitive detector). One of its major use is for kinetic and real time experiments like

the magnetic structures of MnRhAs The magnetic phase transition in MnRhAs have been investigated on D1B by recording the thermal evolution of the powder diffraction pattern over the whole 80° angular range
