In this paper, core-shell like LiAlO2-coated Li1.2Ni0.13Co0.13Mn0.54O2 composite was synthesized by an improved solvothermal method. The surface of the material becomes rough after LiAlO2 coating with a thickness of 5–10 nm. Meanwhile, the surface-coating component with the layer structure α-LiAlO2 can change the dispersion of transition metal elements. When tested in 2.0–4.8 V at 0.05 °C, the initial...
PEI and chitosan are considered to be promising non-viral gene delivery vectors. To improve the transfection efficiency of chitosan, we linked chitosan with polyethylenimine (PEI, Mw=1.8kDa) by 1,1′-carbonyldiimidazole to form a complex. The composition, particle size, as well as the zeta potential of this chitosan-linked-PEI (CP) complex were measured. And the DNA binding ability, cytotoxicity, and...
