Alan Tennant has been appointed director of the Joint Institute for Neutron Sciences at Oak Ridge National Laboratory. The institute is a partnership between ORNL and the University of Tennessee in Knoxville.

“Neutrons are the future in characterizing materials, especially soft matter,” said Taylor Eighmy, vice chancellor for research and engagement at UT. “With Alan as director, we can begin to establish deep thought leadership at UT and ORNL in this growing field.”

Tennant assumes the directorship from Takeshi Egami, the founding director of JINS, who is stepping down after leading the institute for 11 years. Egami will remain as director emeritus as he continues to hold his distinguished scientist position at ORNL and teach at the university.

“I am grateful for Takeshi’s leadership as the founding director of JINS, and I look forward to working with Alan as he continues to propel neutron science at the institute,” Eighmy said. [Read more…]

Helium Atoms into Crystalline Film

Researchers at Oak Ridge National Laboratory have developed a new method to manipulate a wide range of materials and their behavior using only a handful of helium ions.

The team’s technique, published in Physical Review Letters, advances the understanding and use of complex oxide materials that boast unusual properties such as superconductivity and colossal magnetoresistance but are notoriously difficult to control.

For the first time, ORNL researchers have discovered a simple way to control the elongation of a crystalline material along a single direction without changing the length along the other directions or damaging the crystalline structure. This is accomplished by adding a few helium ions into a complex oxide material and provides a never before possible level of control over magnetic and electronic properties.

“By putting a little helium into the material, we’re able to control strain along a single axis,” said ORNL’s Zac Ward, who led the team’s study. “This type of control wasn’t possible before, and it allows you to tune material properties with a finesse that we haven’t previously had access to.” [Read more…]

HED: Silica ‘spiky screws’ could enhance industrial coatings, additive manufacturing

It took marine sponges millions of years to perfect their spike-like structures, but research mimicking these formations may soon alter how industrial coatings and 3-D printed objects are produced.

A molecular process developed by researchers at Oak Ridge National Laboratory paves the way for improved silica structure design by introducing microscopic, segmented screw-like spikes that can more effectively bond materials for commercial use.

The study, conducted by Jaswinder Sharma and his colleagues Panos Datskos and David Cullen, has been published in Angewandte Chemie International Edition. Authors said other applications of the screw-like spikes could include coatings for eyeglasses, television screens, commercial transportation, and even self-cleaning windows and roofs in rural and urban environments.

Created by emulsion droplets applied to a silica particle’s surface, the new, segmented spikes offer an alternative tool for material scientists and engineers that can better maintain and fuse bonds within a variety of microstructures. [Read more…]

Letter: Expansion of DOE waste storage highlights environmental justice problem

To the Editor:

For years, the Oak Ridge National Laboratory and Y-12 have steered their workers to live in surrounding counties. This has boosted those economies—while lowering our home values, financially burdening our schools, and limiting our retail growth.

Now, the U.S. Department of Energy wants to store more of its nuclear waste here.

In the last four years, our two counties (Anderson and Roane) lost 20 percent of their resident DOE workers, costing us an estimated $93 million in annual DOE payroll.

DOE’s economic favoritism is environmentally unfair and politically dumb. It works against the long-term interests of DOE’s important nuclear programs—which need a strong local political base of support to successfully operate. [Read more…]

ORNL: New tool on horizon for surgeons treating cancer patients

Surgeons could know while their patients are still on the operating table if a tissue is cancerous, according to researchers from Oak Ridge National Laboratory and Brigham and Women’s Hospital/Harvard Medical School.

In the journal Analytical and Bioanalytical Chemistry, a team led by ORNL’s Vilmos Kertesz describes an automated droplet-based surface sampling probe that accomplishes in about 10 minutes what now routinely takes 20 to 30 minutes. Kertesz expects that time to be cut to four to five minutes soon. For this proof-of-concept demonstration, researchers rapidly profiled two hormones from human pituitary tissue.

“Instead of having to cut and mount tissue and wait for a trained pathologist to review the sample under a microscope, a technician might soon perform an equally conclusive test in the operating environment,” Kertesz said.

The new mass spectrometry-based technology provides an attractive alternative to the traditional method called immunohistochemistry, or IHC, which looks for specific protein biomarkers to make a diagnosis. Although the IHC approach provides a high degree of spatial recognition, it is time-consuming and limited by the quality and specificity of the antibody used to detect the protein. [Read more…]
