In a study, ORNL researchers concluded that the most direct path to plastic upcycling is through designing polymers specifically for reuse, which would allow the material to be converted into high-value products. Credit: Andy Sproles/ORNL, U.S. Dept. of Energy

Oak Ridge National Laboratory researchers determined that designing polymers specifically with upcycling in mind could reduce future plastic waste considerably and facilitate a circular economy where the material is used repeatedly.

Researchers at Oak Ridge National Laboratory have developed a method of adding nanostructures to high-entropy metal alloys, or HEAs, that enhance both strength and ductility, which is the ability to deform or stretch
Atmospheric Radiation Measurement Data Center in Crested Butte, Colorado.

New data hosted through the Atmospheric Radiation Measurement Data Center at Oak Ridge National Laboratory will help improve models that predict climate change effects on the water supply in the Colorado River Basin.

ORNL researchers used a laser power bed manufacturing technique to 3D print a lightweight aluminum and cerium-based alloy that can withstand temperatures up to 300 degrees Celsius, proving high strength and durability for automotive, aerospace and defense applications.

A multidisciplinary team of scientists at ORNL has applied a laser-interference structuring, or LIS, technique that makes significant strides toward eliminating the need for hazardous chemicals in corrosion protection for vehicles.

The 3D printed concrete smart wall installed at ORNL over the summer was monitored for energy efficiency, with preliminary results showing a minimum of 8% cost savings. Credit: ORNL, U.S. Dept. of Energy

Oak Ridge National Laboratory researchers demonstrated that cooling cost savings could be achieved with a 3D printed concrete smart wall following a three-month field test.

Summer Widner, Stephanie Timbs, James Gaugler and James Avenell of ORNL are part of a team that processes thorium-228, a byproduct of actinium-227. As new uses for thorium are realized, particularly in medicine, the lab expects the demand for the radioisotope to grow.

As a medical isotope, thorium-228 has a lot of potential — and Oak Ridge National Laboratory produces a lot.
