spinel limn2o4 nanorods as lithium ion battery cathodes
Nano Letters, 2008Co-Authors: Do Kyung Kim, Hyun Wook Lee, Pradyumna Muralidharan, Robert A Huggins, Candace K. Chan, Hailin Peng, Riccardo Ruffo, Yuan Yang, Yi CuiAbstract:Spinel LiMn2O4 is a low-cost, environmentally friendly, and highly abundant material for Li-ion battery cathodes. Here, we report the hydrothermal synthesis of single-crystalline β-MnO2 nanorods and their chemical conversion into free-standing single-crystalline LiMn2O4 nanorods using a simple solid-state reaction. The LiMn2O4 nanorods have an average diameter of 130 nm and length of 1.2 μm. Galvanostatic battery testing showed that LiMn2O4 nanorods have a high Charge storage capacity at high power rates compared with commercially available powders. More than 85% of the Initial Charge storage capacity was maintained for over 100 cycles. The structural transformation studies showed that the Li ions intercalated into the cubic phase of the LiMn2O4 with a small change of lattice parameter, followed by the coexistence of two nearly identical cubic phases in the potential range of 3.5 to 4.3V.

mechanisms of site specific photochemistry following core shell ionization of chemically inequivalent carbon atoms in acetaldehyde ethanal
Journal of Chemical Physics, 2016Co-Authors: Sergey Zagorodskikh, J H D Eland, Vitali Zhaunerchyk, Melanie Mucke, Richard J Squibb, P LinussonAbstract:Site-specific fragmentation upon 1s photoionisation of acetaldehyde has been studied using synchrotron radiation and a multi-electron-ion coincidence technique based on a magnetic bottle. Experimental evidence is presented that bond rupture occurs with highest probability in the vicinity of the Initial Charge localisation and possible mechanisms are discussed. We find that a significant contribution to site-specific photochemistry is made by different fragmentation patterns of individual quantum states populated at identical ionisation energies.

dissociation of multiply Charged icn by coulomb explosion
Journal of Chemical Physics, 2016Co-Authors: Sergey Zagorodskikh, J H D Eland, R Singh, James D Pickering, C Slater, Hult A Roos, J AnderssonAbstract:The fragmentations of iodine cyanide ions created with 2 to 8 positive Charges by photoionization from inner shells with binding energies from 59 eV (I 4d) to ca. 900 eV (I 3p) have been examined by multi-electron and multi-ion coincidence spectroscopy with velocity map imaging ion capability. The Charge distributions produced by hole formation in each shell are characterised and systematic effects of the number of Charges and of Initial Charge localisation are found.
