Researchers develop efficient method to measure residual stress in 3D printed parts
LIVERMORE, California – Lawrence Livermore National Laboratory researchers have developed an efficient method to measure residual stress in metal parts produced by powder-bed fusion additive manufacturing.This 3D printing process produces metal parts layer by layer using a high-energy laser beam to fuse metal powder particles. When each layer is complete, the build…
Lawrence Livermore develops infrared camera system to view tokamak from the inside
LIVERMORE, Calif. – General Atomics’ DIII-D Tokamak has been a critical part of the nation’s magnetic fusion energy research since it was built in the 1980s.Over the years, wear and tear has taken its toll. However, it was impossible for researchers to see inside the San Diego company’s highly complicated machine to assess damage -- until now.Lawrence Livermore National…

This popular daylong event is held for girls, grades 6-12, to increase interest in and foster awareness of careers in STEM (science, technology, engineering and…
STEM women part of tri-lab team cutting boundaries
The Department of Energy's 17 national laboratories employ brilliant minds, addressing the greatest science and technology issues facing our planet from climate change and energy solutions to space exploration to national security. Amid these are three nuclear weapons laboratories that share the critical responsibilities of ensuring the safety, security and effectiveness…
Tracing tainted food back to its source
Imagine identifying the source of an outbreak from contaminated foods within hours instead of weeks. That's what several University of Oklahoma (OU) summer interns believe an innovative Lawrence Livermore National Laboratory (LLNL) technology is capable of doing.OU students Alyssa Boutelle, Michael Petri and Lauren Gilbert evaluated a new market opportunity for an…
Chemical engineer selected for national engineering symposium
Rebecca Dylla-Spears will have a chance to collaborate with the nation's top mid-career engineers from industry, academia and government next month.The chemical engineer in the Physics & Life Sciences Directorate at Lawrence Livermore National Laboratory was selected to represent the Lab at the National Academy of Engineering's 20th annual U.S. Frontiers of Engineering…
Livermore researchers create engineered energy absorbing material
Materials like solid gels and porous foams are used for padding and cushioning, but each has its own advantages and limitations. Gels are effective as padding but are relatively heavy; gel performance can also be affected by temperature, and possesses a limited range of compression due to a lack of porosity. Foams are lighter and more compressible, but their performance is…

Lab technology helps companies win Tibbetts Awards
Technology developed by Lawrence Livermore National Laboratory (LLNL) research teams helped two companies win the U.S. Small Business Administration's (SBA)Tibbetts Award recognizing economic impact.STAR Cryoelectronics, LLC of Santa Fe, New Mexico and Inrad Optics of Northvale, New Jersey -- both of which have licensed LLNL technologies -- are two of 25 companies selected…
DARPA taps Lawrence Livermore to develop world's first neural device to restore memory
LIVERMORE, Calif. - The Department of Defense's Defense Advanced Research Projects Agency (DARPA) awarded Lawrence Livermore National Laboratory (LLNL) up to $2.5 million to develop an implantable neural device with the ability to record and stimulate neurons within the brain to help restore memory, DARPA officials announced this week.The research builds on the…
Study shows design standards for dams are effective for earthquakes
There has long been a concern among civil engineers that dams could fail days or weeks after an earthquake, even if no immediate evidence of a problem surfaced.Their concern has focused on possible cracks at the interface between the concrete section of a dam and the soil embankments at the dam's sides, and on how the soil filters nestled amidst the embankments would fare…
Lawrence Livermore, MIT researchers develop new ultralight, ultrastiff 3D printed materials
LIVERMORE, Calif. - Imagine a material with the same weight and density as aerogel -- a material so light it's called 'frozen smoke' -- but with 10,000 times more stiffness. This material could have a profound impact on the aerospace and automotive industries as well as other applications where lightweight, high-stiffness and high-strength materials are needed.Lawrence…
Researchers develop efficient approach to manufacture 3D metal parts
LIVERMORE, Calif. -Lawrence Livermore National Laboratory researchers have developed a new and more efficient approach to a challenging problem in additive manufacturing -- using selective laser melting, namely, the selection of appropriate process parameters that result in parts with desired properties. Selective laser melting (SLM) is a powder-based, additive…
