Engineer develops 'leap forward' with 3D-printer
Lawrence Livermore Lab engineer Bryan Moran wasn’t necessarily looking to improve on 3D printing technology when he moved over to Additive Manufacturing three years ago, but he may have done just that.Moran’s creation, a new take on a process called projection micro-stereolithography, which uses UV light to create 3D objects, won him a coveted R&D 100 award in Las…
Researchers 3D print 'living' blood vessels
The cardiovascular system is a complex web of tens of thousands of miles of arteries, capillaries and veins, branching throughout the body like tributaries of a great river. And now, researchers at Lawrence Livermore National Laboratory are recapitulating this intricate network using an emerging technology: 3D bioprinting."It’s going to change the way we do biology," said…
LLNL wins three 2014 R&D 100 awards
Lawrence Livermore National Laboratory researchers are the recipients of three awards among the top 100 industrial inventions worldwide for 2014. The trade journal R&D Magazine announced the winners of its annual awards, sometimes called the "Oscars of invention," Friday in Las Vegas. With this year's results, the Laboratory has now captured a total of 155 R&D…
Event honors 20 years of Stockpile Stewardship
The proven success of the Stockpile Stewardship Program (SSP) – which pushed the limits of modern science and engineering by requiring the transition from explosive nuclear weapons testing to what is effectively virtual nuclear testing – was celebrated Wednesday at a half-day public event hosted by the Department of Energy’s National Nuclear Security Administration (NNSA)…
3D-printing device wins tech-transfer award
A 3D-printing device developed by a Lawrence Livermore National Laboratory (LLNL) optical engineer has garnered a 2015 Federal Laboratory Consortium (FLC) Far West Region Award for outstanding technology development.The award, given for the Large Area Projection Micro Stereolithography (LAPµSL) technology, was presented to Bryan Moran at the recent FLC Far West/Mid…
LLNL researcher takes aim at solar-cell reliability
A Lawrence Livermore National Lab engineer has been awarded $570,000 through the Department of Energy SunShot Initiative to explore spectroscopic technology as a means of detecting moisture buildup in solar photovoltaic (PV) cells. Over the next two years, Mihail Bora, a Materials Engineering Division (MED) research team member at the Lab, will try to prove that spectral…
Nanocrystals don't add up for reactor materials
Lawrence Livermore researchers have found that nanocrystalline materials do not necessarily resist radiation effects in nuclear reactors better than currently used materials.As researchers hunt for materials with the ability to withstand prolonged radiation damage, the use of nanostructured materials, with high interfacial area to absorb radiation-induced defects, has been…
Lawrence Livermore teams up with Autodesk to investigate design of next-generation materials
Researchers from Lawrence Livermore National Laboratory (LLNL) and a Bay Area company are joining forces to explore how design software can accelerate innovation for three-dimensional printing of advanced materials.Under an 18-month Cooperative Research and Development Agreement (CRADA), LLNL will use state-of-the-art software for generative design from San Rafael-based…

Despite heavy storms and rough seas, Laboratory team captures missile flight data
"Everything was very successful, but this was the toughest mission we’ve ever supported." That was the assessment of Steve Yakuma, LLNL’s ICBM flight test director, when asked to sum up his team’s support of the recently completed GT214 and GT215 missile flight tests off of Saipan in the South Pacific.ICBM test flights are regularly launched from Vandenberg Air Force Base…
Implantable electrode coating good as gold
A team of researchers from Lawrence Livermore and UC Davis have found that covering an implantable neural electrode with nanoporous gold could eliminate the risk of scar tissue forming over the electrode’s surface.The team demonstrated that the nanostructure of nanoporous gold achieves close physical coupling of neurons by maintaining a high neuron-to-astrocyte surface…
3D-printed aerogels improve energy storage
A new type of graphene aerogel will make for better energy storage, sensors, nanoelectronics, catalysis and separations.Lawrence Livermore National Laboratory researchers have made graphene aerogel microlattices with an engineered architecture via a 3D printing technique known as direct ink writing. The research appears in the April 22 edition of the journal, Nature…
