Substantial research activity is currently invested in the pursuit of next generation cathode materials for rechargeable Li-ion batteries. We carry out an initial assessment of the suitability of a recently described empirical potential [J. Phys. Chem. B 2006, 110, 11780] as a rapid, portable, and at least qualitatively accurate computational tool ...
TiO2 has been used as a model system for the surface of medical implant devices based upon titanium alloys. Self Assembled Monolayers (SAM) can be applied via a specific phosphate interaction to modify the surface properties of the TiO2 substrate. Here it is demonstrated via in situ Quartz Crystal Microbalance and Neutron Reflectometry experiments ...
Exploring novel low-cost cathodes for sodium-ion batteries, here we unveil [small beta]-Na2MnP2O7, a new pyrophosphate cathode. Stabilizing into a triclinic structure, it was found to be electrochemically active, delivering a discharge capacity approaching 80 mA h g-1 along with the highest ever Mn3+/Mn2+ redox potential located at 3.6 V. © 2013, R...

Rhodamine 6G (RH6G) laser dye-doped AlPO(4) xerogel and glass were prepared via a simple sol-gel route by one-step process and two-step process, respectively. The aggregating behavior of dyes in xerogel and glass was studied by excitation and emission spectra. The results indicated the dye aggregates become significantly weak in AlPO(4) glass than ...
