Chemical and Morphological Changes of High Voltage Lithium-Manganese Rich Cathodes with Cycling
— Researchers used full-field transmission X-ray microscopy (TXM), capable of 3D imaging at high spatial resolution over a field of view of about 30×30×30 μm, to study the mechanisms driving structural degradation and voltage fade in a high capacity cathode material with nominal composition Li1.2Mn0.525Ni0.175Co0.1O2.

Advances in Understanding Durability of the Building Envelope: ORNL Research
— Moisture, and its accompanying outriders – things like mold, corrosion, freeze damage, and decay – present powerful threats to the durability and long-term performance of a building envelope.

First Annual Housing Innovation Award Winners Announced
— On October 4, 2013, the US Department of Energy (DOE) presented the inaugural winners of the firstever Housing Innovation Awards. The Awards recognize 46 diverse industry leaders bringing the best in energy efficient building technologies and design to new and older homes and helping households save money.

Tips on Homeowner Education
— Homeowner education is a facet of green building that receives little press; yet it is a growing mandate within various green building certification programs.

Perspectives on Next Steps in Residential Energy Efficiency
— “If you ask five people what sustainability means to them, you’ll get five different answers, but if you ask what makes a building sustainable, you may just get the same answer – energy efficiency,” began Linda L. LaCroix, Partner at Aspen Construction Services and Vermont State Representative to the National Association of Home Builders® (NAHB).

ZEBRAlliance Research Project Shows Promising Results
— Energy efficient ground-source heat pumps and energy efficiency are on the way to becoming affordable and increasingly more desirable options for residential use, thanks to new facts gained from a collaborative research project called ZEBRAlliance.

Pushing Boundaries on Performance & Design: the ClimateMaster Trilogy® 40 Q-Mode™ Geothermal Heat Pump – Part II
— The ClimateMaster Trilogy® 40 Q-Mode™ Geothermal Heat Pump is the outcome of a 5 year collaboration between ClimateMaster, Inc., and Oak Ridge National Laboratory (ORNL). The Trilogy 40 Q-Mode is an ultra- high-efficiency geothermal heat pump that provides space heating, cooling, and water heating.

Pushing Boundaries on Performance & Design: the ClimateMaster Trilogy® 40 Q-Mode™ Geothermal Heat Pump
— Introduced July 9, 2012, and available for limited order in December 2012, the ClimateMaster Trilogy® 40 Q-Mode™ Geothermal Heat Pump, the outcome of a 5 year collaboration between ClimateMaster, Inc.

ORNL BioEnergy Science Center funding renewed
— The U.S. Department of Energy today announced it would fund its three Bioenergy Research Centers for an additional five-year period, subject to continued congressional appropriations.

Human mouth microbes provides insight into health, disease
— Microbes from the human mouth are telling Oak Ridge National Laboratory scientists something about periodontitis and more after they cracked the genetic code of bacteria linked to the condition.

ORNL scientists solve mercury mystery
— By identifying two genes required for transforming inorganic into organic mercury, which is far more toxic, scientists today have taken a significant step toward protecting human health.

'Zoomable' map of poplar proteins offers new view of bioenergy crop
— Researchers seeking to improve production of ethanol from woody crops have a new resource in the form of an extensive molecular map of poplar tree proteins, published by a team from the Department of Energy's Oak Ridge National Laboratory (DOE ORNL).

Carbon Fiber Technology Facility marks another milestone
— January 15, 2013 was a big day for the Carbon Fiber Technology Facility. For the first time, technicians conducted a hot test of the oven system with a band of fibers moving through the ov­ens, thus producing a batch of “black” oxidized polyacrylonitrile fiber, or OPF.

XG Sciences, ORNL partner on titanium/graphene composite materials
— XG Sciences, a developer of graphene nanomaterials, and ORNL’s Manufacturing Demonstration Facility are work­ing together to develop a titanium/graphene composite that would have a greater range of applications than titanium alone. The effort uses advanced powder metallurgy manu­facturing processes developed at ORNL.

ORNL MAXLAB occupied, nearing fully equipped status
— Oak Ridge National Laboratory (ORNL) researchers have settled into new offices and laboratories at the MAXLAB—or Maximum Building Energy Efficiency Research Laboratory. Located on Bethel Valley Road, MAXLAB construction was completed at the end of September.

ORNL partners on critical materials hub
— ORNL wins big as part of a team led by Ames Labora­tory, which was selected for an Energy Innovation Hub to address shortages of critical materials, including rare earth metals. The award of up to $120 million over five years for the Critical Materials Institute involves four national labs, academia, and industrial partners.

Additive manufacturing capabilities expanding
— Additive manufacturing capabilities available through ORNL’s Manufacturing Demonstration Facility are expanding to include large-scale polymer additive manufacturing and a new state-of-the-art Arcam A2XX system for metal additive manufacturing.

Kickoff reveals new twists in robotics competition
— Students from dozens of area high schools piled into ORNL's Manufacturing Demonstration Facility in early Janu­ary to get a sense of the obstacles they will be battling over the next six weeks.

Region wins $2.4 million for Advanced Manufacturing and Prototyping Center
— The Advanced Manufacturing and Prototyping Center of East Tennessee (AMP!) is one of a network of public-pri­vate partnerships to help revitalize US manufacturing and encourage companies to invest in the United States.

Decision-making models for reproducing intelligence in transportation
— It could be the start of a good riddle: How many syn­apses of the brain does it take to figure out how to improve fuel efficiency? If you’re Andreas Malikopoulos, Energy and Transportation Science Division researcher and Alvin M. Weinberg Fellow, the answer is far from simple.
