We examine magnetic domain patterns in symmetric ${[\mathrm{Co}/\mathrm{Ni}]}_{M}$ and asymmetric ${[\mathrm{Pt}/{(\mathrm{Co}/\mathrm{Ni})}_{M}/\mathrm{Ir}]}_{N}$ multi-layers by using Fresnel mode Lorentz transmission electron microscopy (LTEM). In

In this work we prepared Li1.2Ni0.2Mn0.6O2 (LNMO) using a hydroxide co-precipitation method and investigated the effect of co-modification with NH4F and Al2O3. After surface co-modification, the first cycle Coulombic efficiency of Li1.2Ni0.2Mn0.6O2 i
