The projected cost had passed $10 billion and the completion date pushed back to 2038, so federal officials were looking for an alternative approach for the proposed Uranium Processing Facility at the Y-12 National Security Complex.

Earlier this year, the National Nuclear Security Administration asked Thom Mason, Oak Ridge National Laboratory director, to lead a team—a so-called “Red Team”—that would develop an alternative approach.

The team’s task was to find a faster, more efficient solution, NNSA Acting Administrator Bruce Held told a House subcommittee on April 3.

On Tuesday, the deadline for submitting a report, Mason said the team has identified a possible alternative and provided information on how the proposal could be implemented if the NNSA adopts it. The next step will be up to the NNSA. Y-12 is an NNSA site.

The goal is to still allow workers to get out of Y-12’s aging Building 9212 by 2025 and keep the cost within an approved range of $4.2 billion to $6.5 billion, Mason said late Tuesday afternoon, when the report was being polished before transmittal. [Read more…]

Anasys Instruments Corp. has licensed an Oak Ridge National Laboratory technology that allows for simultaneous chemical and physical characterization and could lead to advances in  materials and drug development.

The technique, which combines the power of atomic force microscopy and mass spectrometry, fills a void and streamlines analytical processes that are vital to science and industry, said Roshan Shetty, chief executive officer of Anasys Instruments. He also noted that the technology improves the current spatial resolution of ambient methods for mass spectrometry imaging by a factor of more than 100, resulting in imaging resolution as small as 250 nanometers, or 1/400th the thickness of a human hair.

“This capability could have a tremendous impact on a broad field of applications in materials and life sciences ranging from single-cell imaging to polymer composites,” Shetty said. [Read more…]

U.S. Sen. Lamar Alexander on Wednesday called for a special Senate hearing on whether an ongoing review of the Uranium Processing Facility in Oak Ridge could serve as a model to improve oversight of U.S. Department of Energy projects, a press release said.

In a hearing held by the Appropriations Subcommittee for Energy and Water Development, of which he is the lead Republican, Alexander noted that Thom Mason, director of Oak Ridge National Laboratory, is currently conducting a “Red Team” review of UPF. Mason’s Red Team members are using the same process that has made the Office of Science the only office in DOE that successfully manages efficient and cost-effective projects, said Alexander, a Tennessee Republican.

SEATTLE—University of Washington scientists have built the thinnest-known LED that can be used as a source of light energy in electronics, thanks in part to a breakthrough by researchers at Oak Ridge National Laboratory and University of Tennessee in Knoxville.

The LED is based off of two-dimensional, flexible semiconductors, making it possible to stack or use in much smaller and more diverse applications than current technology allows.

“We are able to make the thinnest-possible LEDs, only three atoms thick yet mechanically strong,” said Xiaodong Xu, a UW assistant professor in materials science and engineering and in physics. “Such thin and foldable LEDs are critical for future portable and integrated electronic devices.”

Most consumer electronics use three-dimensional LEDs, but they are up to 20 times thicker than the LEDs being developed. [Read more…]

ORHS team will compete in National Science Bowl

High school students from across Tennessee competed on Saturday, Feb. 22, at Pellissippi State Community College’s Blount County Campus, in the U.S. Department of Energy’s Tennessee Science Bowl competition. Fifty-five high school teams comprised of four students, and one alternate student, answered challenging mathematical problems and tested their knowledge in broad disciplines including chemistry, biology, earth and space science, physics, and energy.

Training for months after school, the student competitors committed hours of study to expanding and honing their mathematics and science knowledge and competition skills. And, all their work showed. Many of the competition rounds came down to the last nail-biting seconds before a winner emerged. However, in the end, Oak Ridge High’s Team 1 edged out their competitors, placing first.

Oak Ridge High School received a $1,000 cash prize, a first-place trophy, and an all-expenses-paid trip to the DOE National Science Bowl in Washington, D.C., from April 24-28, when they will compete against other winning teams from around the nation. [Read more…]

Local Motors and ORNL on 3-D Printing

A new partnership between Local Motors and ORNL will explore vehicle design and construction using 3-D printing technologies. The project will make use of equipment at DOE’s Manufacturing Demonstration Facility, such as the large-scale additive manufacturing machine operated here by ORNL’s Peter LLoyd.

Local Motors Inc. and Oak Ridge National Laboratory have signed a new partnership to develop and deliver technology to produce the world’s first production 3-D printed vehicle.

The cooperative research and development agreement, or CRADA, between Local Motors and ORNL will explore ways to make vehicle construction more efficient—including by lower production time, costs, and part count—and raise standards for control, safety, aesthetics, and mechanical flexibility.

“The primary tool in this drive for efficiency is a combination of material science and cutting-edge advanced manufacturing techniques that are both additive and subtractive,” an ORNL press release said. ORNL is part of the U.S. Department of Energy’s national laboratory system.

“By invoking the principle of open-source, this partnership—and future efforts like it—will drive a true paradigm shift in hardware product development and automotive manufacturing technologies,” said Jay Rogers, co-founder and chief executive officers of Local Motors. “Just as exciting as the vision of delivering the first direct digital manufactured car is that we will be engaging future consumers to contribute and evangelize its creation. We are living in a time when speed to market trumps slow-going protectionism. Local Motors’ open development platform is what delivers this very speed.” [Read more…]

ORNL and UT researchers have invented a method to merge different 2-dimensional materials into a seamless layer. This colorized scanning tunneling microscope image shows a single-atom sheet composed of graphene (seen in blue) combined with hexagonal boron nitride (seen in yellow).

Researchers at Oak Ridge National Laboratory and the University of Tennessee in Knoxville have pioneered a new technique for forming a two-dimensional, single-atom sheet of two different materials with a seamless boundary.

The study, published in the journal Science, could enable the use of new types of 2-D hybrid materials in technological applications and fundamental research.

By rethinking a traditional method of growing materials, the researchers combined two compounds—graphene and boron nitride—into a single layer only one atom thick. Graphene, which consists of carbon atoms arranged in hexagonal, honeycomb-like rings, has attracted waves of attention because of its high strength and electronic properties. [Read more…]

ORNL devises recipe to fine-tune silica rod diameters

By controlling the temperature of silica rods as they grow, researchers at Oak Ridge National Laboratory could be setting the stage for advances in anti-reflective solar cells, computer monitors, TV screens, eye glasses, and more.

The goal of fabricating fixed-size one-dimensional silica structures and being able to precisely control the diameter during growth has long eluded scientists. Now, Panos Datskos and Jaswinder Sharma have demonstrated what they describe as the addressable local control of diameter of each segment of the silica rod.

“In nature, many intricate structures develop and grow in response to their environments,” said Sharma, a Wigner Fellow and corresponding author of the Angewandte Chemie International Edition paper that outlines the process. “For example, in addition to genotype, shell shape is also controlled by the local environment in many oysters and scallops.” [Read more…]
