Investigation on the microstructures of the Li-ion battery cathodes using transmission electron microscopy, to understand the failures or working mechanisms down to the atomic level

To Create New Multiferroics; Synthesis of the New NaLnCoWO6 Family; Structure and Composition Study by X-ray and Neutron Powder Diffraction, TEM, SEM, EDX; Structure Refinement by Rietveld Method, the Nine New Compounds Found to Be Polar; Modulated Structures in Some Compounds Studied by TEM and STEM; Magnetic, and (Di)Electric Measured by MPMS, PPMS, and Home-made Cryostat Setup, the ME Coupling Experimentally Observed in The Material Class AA’BB’O6 for the First Time; Magnetic Structure Determined

To compare different approaches to optimise the resistance such like edge- or top-contact configuration, different contact metals, wet chemistry clean, plasma treatment, thermal annealing, ultraviolet ozone treatment and degassing. TiPd Contact, Thermal Annealing and Degassing Evidenced to Be Promising; Electrical Resistance Characterization

We synthesized a new doubly ordered perovskite family NaLnCoWO6 to pursue multiferroics. Their structures (X-ray, neutron, electron microscopy) and physical properties (magnetism, electricity) were systematically investigated over the series. The ME coupling was observed firstly.
