Three cationic lipids with lysylated(1),histidylated(2),and arginylated(3) headgroups and cholesterol hy-drophobic moiety were synthesized.The average sizes of
Polyacrylonitrile(PAN)/Fe 3 O 4 composite nanofibers were successfully obtained through electrospinning and sol-gel technology. The resulting magnetic Fe 3 O 4
