Purpose and sacrifice mark offsite assignment

June 23, 2016 -  
When Daryl Boyer was asked to lend his technical expertise to help shape the future of the U.S. nuclear deterrent, he knew it meant relocating to Omaha, Nebraska, without his parents and children. But the challenge called him and the timing was right. He acted decisively. Boyer is an LLNL engineer...

Lawrence Livermore team improves 3D-printed graphene aerogel supercapacitors

June 16, 2016 -  
Lawrence Livermore National Laboratory (LLNL) researchers, along with a team from UC Santa Cruz (UCSC), have devised a method for doubling the performance of 3D-printed graphene-based supercapacitors. The method, which involves sandwiching lithium ion and perchlorate ion between layers of graphene...

‘Human-on-a-chip’ could replace animal testing

June 2, 2016 -  
Development of new prescription drugs and antidotes to toxins currently relies extensively on animal testing in the early stages of development, which is not only expensive and time consuming, it can give scientists inaccurate data about how humans will respond to such agents. But what if...

Lawrence Livermore discovery a ‘big step forward’ for metal 3-D printing process

May 25, 2016 -  
Researchers at Lawrence Livermore National Laboratory (LLNL) have taken a major step toward answering a question plaguing a common metal 3-D printing technique: What interactions can lead to the porosity found in parts produced by laser powder-bed fusion processes? In a paper published in the May...

Researchers outline physics of metal 3D printing

Jan. 14, 2016 -  
While the most common method of metal 3D printing is growing exponentially, moving forward from producing prototypes to manufacturing critical parts will be possible only by reaching a fundamental understanding of the complex physics behind the process, according to a new paper authored by Lawrence...
