LLNL scientists discover a new way that metals freeze at extreme conditions

Feb. 22, 2021- 
Since the dawn of civilization, metallurgy has determined the fate of powerful cities, states and empires. Blacksmiths have harnessed the power of heat to melt simple metals that would then be cast into hard, sharp and shiny alloys. Varying process conditions, such as rate of cooling and composition, can lead to new materials with dramatically different mechanical properties, such as...

Research on transition phenomena to aid in improving safety of explosives

Feb. 16, 2021- 
On Aug. 4, 2020, a massive explosion rocked Lebanon’s capital of Beirut, sending shockwaves through the city and shattering windows, reducing some buildings to rubble and killing at least 200 people. Officials have since traced the blast to a stockpile of more than 2,500 tons of confiscated ammonium nitrate stored in a port warehouse. While the official investigation is ongoing, it...

What Hollywood gets wrong, and right, about asteroids

Feb. 11, 2021- 
Meet Kirsten Howley, the real-life astrophysicist working to prevent an asteroid “Armageddon” In the 1998 movie “Armageddon,” an asteroid the width of Texas is about to hit Earth.

Scientists measure temperature under shock conditions

Feb. 8, 2021- 
Temperature is tough to measure, especially in shock compression experiments. A big challenge is having to account for thermal transport — the flow of energy in the form of heat. To better understand this challenge, researchers from Lawrence Livermore National Laboratory (LLNL) have taken important steps to show that thermal conduction is important and measurable at high pressure and...
