LLNL project aims to transform electrical grid resiliency with distributed energy resources

Sep. 28, 2017 -  
In the event of a major earthquake, hurricane or flood, electricity might be lost for days, affecting communications, recovery efforts and people’s lives. Normally, in a large-scale emergency, distributed energy resources (DERs) -- such as the energy produced by solar panels at customers’ homes --...

Lab researchers achieve '4D printed' material

Sep. 13, 2017 -  
For the first time, Lawrence Livermore National Laboratory ( LLNL ) researchers have successfully 3D printed composite silicone materials that are flexible, stretchable and possess shape memory behavior, a discovery that could be used to create form-fitting cushioning activated by body heat, such...

LLNL finds reason behind defects in 3D printing

Aug. 1, 2017 -  
High-speed images of a common laser-based metal 3D printing process, coupled with newly updated computer models, have revealed the mechanisms behind material redistribution, a phenomenon that leads to defects in printed metal parts, Lawrence Livermore National Laboratory (LLNL) researchers reported...

Lab loans state-of-the-art 3D printer to Cal Poly

Jun. 7, 2017 -  
California Polytechnic State University (Cal Poly) San Luis Obispo engineering students now have access to the state-of-the-art in metal additive manufacturing and the ability to perform contracted work for Lawrence Livermore National Laborator y (LLNL), thanks to a new Selective Laser Melting (SLM...

NIF technology could revolutionize 3D printing

May. 25, 2017 -  
A technology originally developed to smooth out and pattern high-powered laser beams for the National Ignition Facility ( NIF ) can be used to 3D print metal objects faster than ever before, according to a new study by Lawrence Livermore researchers. A team of Lab scientists report the findings in...

LLNL and LBNL researchers explore more energy-efficient solutions for paper industry

May. 16, 2017 -  
If you had to name the industries in the United States that use the most energy, paper manufacturing probably wouldn’t immediately come to mind. In fact, the paper-making industry ranks third among the country’s largest energy users, behind only petroleum-refining and chemical production, according...

Lawrence Livermore unveils 'heart-on-a-chip'

May. 11, 2017 -  
Prescription drugs have enabled millions of Americans with chronic medical conditions to live longer and more fulfilling lives, but many promising new drugs never make it to the human trials stage due to the potential for cardiac toxicity. Through “heart-on-a-chip” technology — modeling a human...
