Advanced Materials and Manufacturing

Adding an optimized void structure (top right) counteracts a shockwave-induced instability, reducing jetting (bottom right) that can interfere with inertial confinement fusion. Without this void, significant jetting occurs (bottom left). (Image: Strucka et al.)

Looking into the void to cancel out material instabilities

Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that wave hits a bump in the material interface, it slows down. If it hits a dent, it accelerates forward. This imbalance creates fast, narrow jets of material — called the Richtmyer…

Some of the toughest challenges in American manufacturing are being solved without ever stepping onto a factory floor. Inside supercomputers, scientists are modeling systems too complex, costly or time-consuming to test in the real world. In the latest episode of the Big Ideas Lab podcast, Lawrence Livermore National Laboratory (LLNL) spotlights the High-Performance…

Cryogenic micro-calorimetry offers a novel material-dating method for nuclear forensics and safeguards

The moment nuclear material is produced, processed or purified, it sets off a hidden countdown, marked by the half-life of its radioactive atoms as they begin to decay. For scientists tracking the origins of these substances, decoding this natural clock is crucial for verifying material histories in support of global security efforts. In a new study published in the…

In a new study, researchers genetically engineered the metabolic pathways in yeast to consume sugar and produce oxalic acid. The latter can be used to separate rare earth elements from other metals. (Graphic: Dan Herchek/LLNL)

Engineered yeast produce acids needed to refine rare-earth elements

From mining to magnet manufacturing, the process for refining rare-earth elements is complex and intensive. The supply chain for such critical materials is dominated by China — and so is the oxalic acid needed for the separation and purification stages. To move toward a U.S. supply chain for rare-earth element recovery, researchers from Lawrence Livermore National…

Big Ideas Lab NIF target fabrication

Big Ideas Lab podcast zooms in on tiny targets

At the end of an inertial confinement fusion (ICF) experiment at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), the target, measuring just two centimeters, is mostly obliterated. The gold plating, the high-density carbon and months of meticulous assembly vanish in an instant. That’s the point. In that flash, the target becomes what NIF is built…

By adding a lid-like structure to a carbon nanotube, LLNL researchers mimicked how biological channels open and close to allow ion transport.

Nanotubes with lids mimic real biology

When water and ions move together through channels only a nanometer wide, they behave in unusual ways. In these tight spaces, water molecules line up in single file. This forces ions to shed some of the water molecules that normally surround them, leading to the unique physics of ion transport. Biological channels are especially adept at this behavior, often choreographing…

From fleeting to stable: scientists uncover recipe for new carbon dioxide-based energetic materials

When materials are compressed, their atoms are forced into unusual arrangements that do not normally exist under everyday conditions. These configurations are often fleeting: when the pressure is released, the atoms typically relax back to a stable low-pressure state. Only a few very specific materials, like diamond, retain their high-pressure structure after returning to…
