Enhancing the Efficiency of Solar Energy Conversion in Titania
— A new method that simultaneously incorporates chromium (Cr) and nitrogen (N) atoms as Cr-N pairs into titania yields a material with an extraordinarily large (> 1 eV) band gap reduction.

Electronic properties of manganite surfaces robust against reduction
— While the broad range of properties of complex oxides degrade severely with decreasing oxygen content, it has now been shown that the electronic properties at their surfaces can remain unaffected in a reducing environment. This discovery carries important implications for the design of functional complex oxides for energy efficient catalysis and batteries that depend on these surface properties.

Revealing the rapid isothermal growth of graphene on catalytic substrates
— Real-time optical diagnostics reveal that graphene nucleates and grows rapidly and isothermally on Ni substrates by dissolution and precipitation of carbon; the flux-dependent kinetics indicate autocatalytic reactions.

Condensed phase growth of nanooysters from Fe-decorated single-wall carbon nanohorns
— New hybrid "nanooysters" consisting of encapsulated metal nanoparticles inside hollow carbon shells were synthesized by transforming single-wall carbon nanohorns with reactive metals in a rapid, high-temperature annealing process.
