July 25, 2016 - Advanced Science has received its first impact factor: 6.00. A bit of history: the front cover of the first issue back in 2014 came from our group. Coincidentally 31 years ago when Advanced Materials launched its first changable graphic-based front cover, the cover story was from our group, too. Our group cover gallery can be accessed here.
July 25, 2016 - Kulbir's perspective article titled "Surface Analogs of Molecular Frustrated Lewis Pairs in Heterogeneous CO2 Hydrogenation Catalysis" accepted by ACS Catalysis. Congratulations, Kulbir! The article discusses whether or not thinking about surface acidity and basicity in terms of FLPs is something new or something old, something useful and serves a practical purpose or something uninformative and unhelpful.

July 06, 2016 - Jia Jia and Paul G. O'Brien's work on the reverse water gas shift (RWGS) reaction driven by Nb2O5 nanorod-supported Pd nanocrystals was published in Advanced Science. This work represents a significant enhancement in our understanding of the underlying mechanism of photothermally driven CO2 reduction and will help guide the way toward the development of highly efficient catalysts that exploit the full solar spectrum to convert gas-phase CO2 to valuable chemicals and fuels. The full article can be found on the Adv. Sci. website.
June 16, 2016 - In a review authored by Wei Sun, Chenxi Qian, and Kenneth Chen of our Silicon team, recent studies in the literature on size dependent properties of mono-disperse Silicon nanocrystals is summarized. The full article can be found on the ChemNanoMat website.
June 15, 2016 - Laura’s investigation on the effect catalyst precursors play in the photocatalytic activity of In2O3 is described in her recent Chemistry of Materials paper. It was observed that the active form, a defected In2O3-x(OH)y is formed upon thermal decomposition of In(OH)3, whereas In(NO3)3 decomposition results in a more stoichiometric but less active In2O3. This study further sheds light on the importance of surface defects in heterogeneous photocatalysis. The full article can be found on the Chemistry of Materials website.
