Diamond anvil cell behavior up to 4 Mbar
Diamond anvil cell behavior up to 4 Mbar
Since its invention, the diamond anvil cell (DAC) has been one of the most essential tools used to simulate ultrahigh pressure conditions in multidisciplinary research fields. Recently, a research team led by Dr. Ho-kwang Mao conducted in situ high-pressure synchrotron X-ray diffraction and absorption measurements to study the loading behaviors of the beveled DAC by using the submicrometer synchrotron X-ray beam at the Advanced Photon Source (APS) at Argonne National Laboratory (ANL). The investigation presented a comprehensive understanding of variables that affect the achievement of ultrahigh pressures. This study established a solid foundation for future development of DAC techniques.More...

Syntheses, structure and properties of a new Fillowite-type compound Na0.48Mn1.22PO4
Syntheses, structure and properties of a new Fillowite-type compound Na0.48Mn1.22PO4
Scientists recently synthesized a new Fillowite-type NMPO compound, Na0.48 Mn1.22PO4, by using solid-state reaction. Within the new NMPO system, Mn binds O as a 3D Mn-O-Mn network with the insertion of some Mn5O6. The valence of Mn was confirmed in HPSynC by using the facilities at APS at Argonne National Lab. Further electrochemical tests indicated that the new NMPO compound has great potential in Na-ion battery applications, a low cost and environmental friendly energy storage alternative to Li-ion batteries.More...
