Research Progress and Perspective on Lithium/Sodium Metal Anodes for Next-Generation Rechargeable Batteries.

With the development of consumer electronic devices and electric vehicles, lithium-ion batteries (LIBs) are vital components for high energy storage with great impact on our modern life. However, LIBs still cannot meet all the essential demands of rapidly growing new industries. In pursuance of higher energy requirement, metal batteries (MBs) are the next-generation high-energy-density devices.

Nanostructure induced metal-insulator transition and enhanced low-field magnetoresistance in La0.7 Sr0.3MnO3 systems.

We investigated implications of nanostructure formation on structural and magnetotransport properties of La0.7Sr0.3MnO3 compound.

Nanoscale switching characteristics of nearly tetragonal BiFeO3 thin films.

We have investigated the nanoscale switching properties of strain-engineered BiFeO(3) thin films deposited on LaAlO(3) substrates using a combination of scanning probe techniques. Polarized Raman spectral analysis indicates that the nearly tetragonal films have monoclinic (Cc) rather than P4mm tetragonal symmetry. Through local switching-spectroscopy measurements and piezoresponse force microscopy, we provide clear evidence of ferroelectric switching of the tetragonal phase, but the polarization direction, and therefore its switching, deviates strongly from the expected (001) tetragonal axis.
