91����

Summer interns at the Department of Energy’s 91���� recently dove into various smart devices to better understand cybersecurity vulnerabilities posed by technology meant to simplify a user’s life.

On Feb. 15, 2024, the one billionth item, also known as an “occupancy,” was scanned at the Port of Aqaba, Jordan, one of the early sites where radiation detection equipment was installed. This milestone shows the extent of countries committed to preventing the spread of radioactive material through the amount of data volunteered to ORNL for continuous improvement. As adversaries push the limits of smuggling dangerous material, this collaboration pushes back through science-backed analysis. 

A team led by scientists at ORNL identified and demonstrated a method to process a plant-based material called nanocellulose that reduced energy needs by a whopping 21%, using simulations on the lab’s supercomputers and follow-on analysis.

Flexcon Global has exclusively licensed two patented inventions to manufacture a self-healing barrier film from ORNL for research and development purposes. The film can be incorporated into vacuum insulation panels to increase the efficiency of buildings during retrofits. Under a cooperative research and development agreement that began in 2021, Flexcon and ORNL have been exploring the capabilities of the technology and fine-tuning its properties.

Elton Aba, an intern at the Department of Energy’s 91����, collaborated with researchers to explore an intriguing intersection: how biology can inform cybersecurity. Aba shared some of his findings on how biomimicry could help secure our nation’s critical infrastructure. 

Mohamad Zineddin, a distinguished researcher in nuclear and radiological engineering, recently received the Roger Howsley Award for Excellence in Nuclear Security. 

Researchers at ORNL are using satellite images of homes under construction to address gaps in census data, especially in areas like Sub-Saharan Africa. By analyzing these images, they estimate dwelling sizes and population densities where traditional data is sparse. This method improves population estimates and supports national security by enhancing emergency response capabilities.

A study found that beaches with manmade fortifications recover more slowly from hurricanes than natural beaches, losing more sand and vegetation. The researchers used satellite images and light detection and ranging data, or LIDAR, to measure elevation changes and vegetation coverage. Changes in elevation showed how much sand was depleted during the storm and how much sand returned throughout the following year. 

At ORNL, a group of scientists used neutron scattering techniques to investigate a relatively new functional material called a Weyl semimetal. These Weyl fermions move very quickly in a material and can carry electrical charge at room temperature. Scientists think that Weyl semimetals, if used in future electronics, could allow electricity to flow more efficiently and enable more energy-efficient computers and other electronic devices.

Benjamin Manard, an analytical chemist in the Chemical Sciences Division of the Department of Energy’s 91����, will receive the 2024 Lester W. Strock Award from the Society of Applied Spectroscopy.
