As industries and consumers increasingly seek improved battery power sources, cutting-edge microscopy performed at the Department of Energy's Oak Ridge National Laboratory is providing an unprecedented perspective on how lithium-ion batteries function. A research team led by ORNL's Nina Balke, Stephen Jesse and Sergei Kalinin has developed a new type of scanning probe microscopy called electrochemical strain microscopy (ESM) to examine the movement of lithium ions through a battery's cathode...

Nanoscale simulations and theoretical research performed at the Department of Energy's Oak Ridge National Laboratory are bringing scientists closer to realizing graphene's potential in electronic applications. A research team led by ORNL's Bobby Sumpter, Vincent Meunier and Eduardo Cruz-Silva has discovered how loops develop in graphene, an electrically conductive high-strength low-weight material that resembles an atomic-scale honeycomb. Structural loops that sometimes form during a graphene...

Thin layers of oxide materials and their interfaces have been observed in atomic resolution during growth for the first time by researchers at the Center for Nanophase Materials Sciences at the Department of Energy's Oak Ridge National Laboratory, providing new insight into the complicated link between their structure and properties. "Imagine you suddenly had the ability to see in color, or in 3-D," said the CNMS's Sergei Kalinin. "That is how close we have been able to look at these very...

The Department of Energy's Spallation Neutron Source (SNS), already the world's most powerful facility for pulsed neutron scattering science, is now the first pulsed spallation neutron source to break the one-megawatt barrier. "Advances in the materials sciences are fundamental to the development of clean and sustainable energy technologies. In reaching this milestone of operating power, the Spallation Neutron Source is providing scientists with an unmatched resource for unlocking the secrets...

Electronic devices of the future could be smaller, faster, more powerful and consume less energy because of a discovery by researchers at the Department of Energy's Oak Ridge National Laboratory.The key to the finding, published in Science, involves a method to measure intrinsic conducting properties of ferroelectric materials, which for decades have held tremendous promise but have eluded experimental proof. Now, however, ORNL Wigner Fellow Peter Maksymovych and co-authors Stephen Jesse, Art...

The U.S. Department of Energy has given its initial approval to begin plans for a second target station for the Spallation Neutron Source, expanding what is already the world's most powerful pulsed neutron scattering facility located at DOE's Oak Ridge National Laboratory.The Critical Decision Zero (CD-0) status is the first step in an approximately $1 billion construction project. The Second Target Station (STS) will be optimized for nanoscale and biological sciences with an emphasis on...

OAK RIDGE, Tenn., Aug. 19, 2005 "” The Spallation Neutron Source at the Department of Energy's Oak Ridge National Laboratory has met a crucial milestone on its way to completion in June 2006 -- operation of the superconducting section of its linear accelerator. The SNS linac has two sections: a room-temperature, or warm, section, which completed its commissioning last January, and a superconducting, or cold, section, which operates at temperatures hundreds of degrees below zero. The...
