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…

CASIS workshop explores building a Wikipedia for visual queries

The 18th annual Signal and Image Sciences Workshop, a signature event of the Engineering Directorate's Center for Advanced Signal and Image Sciences (CASIS), attracted more than 100 attendees last week.The workshop is designed to showcase R&D in signal and image sciences at Lawrence Livermore and Sandia national laboratories as well as local academic institutions and…

A computer code led to entrepreneurial success

Editor's note: This article is part of an occasional series about LLNL entrepreneurs. John Hallquist knew it was a game changer when he invented a small computer code to analyze the structures of bombs dropped by U.S. Air Force jets. It was 1976 and Hallquist was a young engineer who had joined Lawrence Livermore National Laboratory after getting his Ph.D. from Michigan…

UC Merced students inspired by Laboratory visit

UC Merced students spent Friday touring Lawrence Livermore National Laboratory (LLNL), a place where some of them dream of working as a scientist or engineer. The group included 20 undergraduate and graduate students from the university's science, technology, engineering and mathematics (STEM) Resource Center. The purpose of the visit was for LLNL to strengthen its…

Lab researcher inspired by math

What makes Carol Meyers tick is a series of proofs, theorems and complex equations.The self-described "nerd" has loved mathematics since she was young, and it has helped her succeed as a researcher in Lawrence Livermore National Laboratory's Computational Engineering Division."I've always loved numbers," Meyers said. "I like to think logically. Higher math allows me to…

Visiting engineering professor works on materials designed for additive manufacturing

Many professors publish research papers but never get to see their research move into the development phase.That's not the case for Daniel Tortorelli, an engineering professor at the University of Illinois Urbana-Champaign.He recently completed a nine-week sabbatical at Lawrence Livermore National Laboratory, where his research on structural optimization was put to use in…

Livermore Lab shines new light on novel additive manufacturing approach

For nearly a century, electrophoretic deposition (EPD) has been used as a method of coating material by depositing particles of various substances onto the surfaces of various manufactured items. One of the most common and oldest processes that utilize EPD is the application of a primer coat to new car bodies on a production assembly line. The body of the car is positively…
