ORNL researchers combined 3D printing and PM-HIP to make large metal parts faster, cheaper and with less waste. The process enables complex, high-performance components for nuclear, aerospace and energy applications while helping strengthen U.S. manufacturing and supply chains.
ARC and ORNL signed an MOU to accelerate AI-enabled, on-demand production of qualified, mission-critical components for U.S. national security applications. The partnership will combine ORNL's computing and manufacturing capabilities with ARC's ARCNet distributed manufacturing platform to create a closed-loop system for AI-enabled materials and manufacturing qualification and autonomous production at defense-relevant scale.
Tennessee Tech chemistry students are spending the summer at ORNL gaining hands-on experience in radiochemistry research while helping develop improved methods for separating the rare isotope promethium-147. The collaboration, supported by DOE’s RENEW initiative, is also aimed at strengthening the future nuclear science workforce by preparing students for careers at national laboratories and in isotope research.
ORNL and startup Vitriform3D are transforming discarded glass bottles into durable new products using 3D-printing technology. By crushing recycled glass into powder and using a binder jetting process, the team is creating decorative tiles, building materials, and other products while reducing landfill waste and exploring new sustainable manufacturing applications.
Researchers at ORNL developed new experimental methods to measure how uranium-bearing molten salts conduct heat and flow, providing critical data for advancing molten salt reactor technologies. Using specialized tools developed at ORNL, the team generated unique thermal conductivity and viscosity data that will help improve reactor models, support licensing efforts, and expand the Molten Salt Thermal Properties Database.
Researchers at ORNL’s Center for Nanophase Materials Sciences are developing autonomous workflows that combine advanced instruments, AI, simulations and theory to accelerate microelectronics research. These systems can interpret experimental data in real time, guide next steps during materials synthesis and analysis, and help scientists better understand and optimize next-generation materials for memory devices and transistors.
ORNL has named Katherine Kate Evans as associate laboratory director for the Biological and Environmental Systems Science Directorate. Evans will lead the directorate as it advances the science and technology needed to strengthen energy security, safeguard infrastructure and accelerate biotechnology innovation.
ORNL scientists demonstrated a new way to make aluminum nitride store data using far less energy by creating controlled defects with a focused helium ion beam. The approach reduced the energy needed for polarization switching by about 40% and could support more efficient memory and wireless communication devices using existing chip manufacturing methods.
Researchers at ORNL developed an on-machine monitoring system that uses a tactile sensor and algorithms to detect cutting tool wear with about 98% accuracy in seconds. The system provides consistent, real-time feedback unaffected by lighting, helping manufacturers reduce downtime, optimize tool use and lower costs.
Orlando J. Rojas has been named the University of Tennessee-Oak Ridge National Laboratory Governor’s Chair for Circular Biomaterials. An internationally recognized leader in sustainable materials science, Rojas will hold a joint appointment in UT’s Herbert College of Agriculture and ORNL beginning in late 2026.
