Vortex Pinning and the Mechanism in CaKFe4As4 Revealed by Dynamical Magnetization Relaxation
We have studied the vortex dynamics of CaKFe4As4 single crystals using a dynamical magnetization relaxation method. A large region of vortex elastic motion is observed indicating strong vortex pinning ability. Te...

CoO nanorod arrays on carbon nanotube foams fabricated by reducing carbon dioxide as high-performance electrode materials for Li-ion batteries
We have successfully synthesized 3D carbon nanotube foams through a simple self-assembly method. Taking these carbon nanotube foams as substrates, we have fabricated a novel core-shell structure of CNTF@CoO th...
