A new computational materials chemistry method quantitatively details the behavior of alloyed nanocatalysts under working conditions. Catalysts can undergo a variety of changes induced by the chemical environment in which they operate. A nanocatalyst’s surface composition depends on the overall composition of the catalyst and its local chemical environment. Scientists showcased the power of their method using a 50:50 palladium-rhodium catalyst in an oxygen environment. Without any oxygen, a palladium shell forms; conversely, with oxygen present rhodium elbows palladium out of the way t
|For Ames Laboratory's holiday greeting this year, Public Affair videographer Brian Marczewski created an animated construction scene of the Sensitive Instrument Facility that concludes with a decorated tree hoisted atop the building that morphs into the Ames Laboratory logo. Check it out!|

|The 14th annual Ames Laboratory Employees Holiday Auction raised just over $5,000, setting a new record. It also boosted the total amount raised for local charities to more than $41,000. This year the money was split between Heartland Senior Services and the Bethesda Community Food Pantry.|
Ames Laboratory scientist Cai-Zhuang Wang, a senior scientist at the Ames Laboratory, was named a 2014 Fellow of the American Physical Society (APS).
According to APS, Wang was elected for “significant advances in developing computation methods including tight-binding molecular dynamics for atomistic simulations, genetic algorithm for crystal and interface structure prediction, and Gutzwiller density functional theory for strongly correlated electron systems.”
