The 2011 Journal of Materials Chemistry Lectureship recipient, Liberato Manna, has published a paper on cubic and hexagonal phases of copper-sulfur-selenium alloys which exhibit a well-defined near-infrared valence band plasmon resonance. The nanocrystals were then evaluated as an anode material in Li-ion batteries, and were capable of undergoing lithiation/delithiation via a displacement/conversion reaction (Cu to Li and vice versa) in a partially reversible manner.
His work was highlighted on the back cover of the journal, and can be read by clicking on the link below:
