Abstract

The steep rhombohedra MnCO3microcrystals and their large-scale assembly into regular elongated patterns are obtained viaa novel surfactant-free route by adjusting the proportion of the mixed solvent (methanol and DMF). We hope this synthetic strategy can provide a new approach to synthesize metal carbonates. [ABSTRACT FROM AUTHOR]

Abstract

Ammonium phosphate ((NH4)3PO4) has been first used as a surface treatment reagent for Li-rich cathode materials. Compared to the conventional surface treatment, the samples treated with (NH4)3PO4 exhibit an ultra-high initial Coulomb efficiency of 98.0% and excellent cycling stability. This is mainly attributed to the simultaneous construction of surface integrated structures, including oxygen vacancies, spinel phases, and Li3PO4 coating. This study demonstrates the effectiveness of ammonium phosphate surface treatment and provides a new idea for designing other cathode materials. [ABSTRACT FROM AUTHOR]

Abstract

Ferrimagnetic Fe3S4nanowalls and triple hierarchical microspheres have been fabricated viaan ionic liquid-modulated solution–phase process, respectively. Magnetic hysteresis measurements demonstrate that their morphology–dependent magnetic properties might be originated from their unique nanostructures. [ABSTRACT FROM AUTHOR]
