Coexistence of ferroelectricity and ferromagnetism in a rubidium manganese hexacyanoferrate.

Low Voltage Charge/Discharge Behavior of Manganese Hexacyanoferrate

Recently, Prussian blue analogues (PBAs) have been reported to exhibit a low voltage charge/discharge behavior with high capacity (300–545 mAh/g) in lithium-ion secondary batteries (LIBs). To clarify the mechanism of low voltage behavior, we performed ex situ synchrotron radiation X-ray diffraction (XRD) and ex situ X-ray absorption spectroscopy (XAS) of a film of Na1.34Mn[Fe(CN)6]0.84·3.4H2O w...

Glucose-Treated Manganese Hexacyanoferrate for Sodium-Ion Secondary Battery

Manganese hexacyanoferrate (Mn-PBA) is a promising cathode material for sodium-ion secondary battery (SIB) with high average voltage (=3.4 V) against Na. Here, we find that the thermal decomposition of glucose modifies the surface state of Mn-PBA, without affecting the bulk crystal structure. The glucose treatment significantly improves the rate properties of Mn-PBA in SIB. The critical dischar...

Multifunctional Topology Design of Cellular Material Structures

1 This is a revised version of Paper Number DETC2006-99373, published in the ASME Advances in Design Automation Conference. ABSTRACT Prismatic cellular or honeycomb materials exhibit favorable properties for multifunctional applications such as ultra-light load bearing combined with active cooling. Since these properties are strongly dependent on the underlying cellular structure, design method...

Size dependence of the photoinduced magnetism and long-range ordering in Prussian blue analog nanoparticles of rubidium cobalt hexacyanoferrate

Nanoparticles of rubidium cobalt hexacyanoferrate (RbjCok[Fe(CN)6]l · nH2O) were synthesized using different concentrations of polyvinylpyrrolidone (PVP) to produce four different batches of particles with characteristic diameters ranging from 3 to 13 nm. Upon illumination with white light at 5 K, the magnetization of these particles increases. The long-range ferrimagnetic ordering temperatures...
