Atomistic simulations go the distance on metal strength

29-Sep-2017

Lawrence Livermore National Laboratory researchers have dived down to the atomic scale to resolve every "jiggle and wiggle" of atomic motion that underlies metal strength. In a first of its kind series of computer simulations focused on metal tantalum, the team predicted that, on reaching certain ...

Outperforming nature's water filtration ability with nanotubes

29-Aug-2017

At just the right size, carbon nanotubes can filter water with better efficiency than biological proteins, a new study reveals. The results could pave the way to new water filtration systems, at a time when demands for fresh water pose a global threat to sustainable development. A class of ...

3D printed metamaterial shrinks when heated

26-Oct-2016

Members of Lawrence Livermore National Laboratory's Additive Manufacturing Initiative are among a group of researchers who have developed 3D printed materials with a unique property -- instead of expanding when heated, they shrink. In a study LLNL engineers, along with scientists from the ...

Scientists identify enzymes that create a highly toxic form of mercury in Antarctic sea ice

02-Sep-2016

Researchers from Lawrence Livermore National Laboratory (LLNL) assisted a team from the University of Melbourne in discovering how methylmercury enters the Antarctic sea and bioaccumulates in the marine food web. LLNL scientists Michael Thelen and Adam Zemla performed protein sequence analysis ...

Feeling the force between sand grains

26-Aug-2016

For the first time, Lawrence Livermore National Laboratory (LLNL) researchers have measured how forces move through 3D granular materials, determining how this important class of materials might pack and behave in processes throughout nature and industry. Granular materials such as sand, soil and ...

Putting pressure on 3D-printed structures

29-Jun-2016

Through a series of dynamic compression experiments on additively manufactured (AM) structured lattices, a Lawrence Livermore National Laboratory team, supported by colleagues at Los Alamos National Laboratory, has found that the assemblies have unique properties not exhibited by disordered ...

New 3-D printed polymer can convert methane to methanol

17-Jun-2016

Lawrence Livermore National Laboratory scientists have combined biology and 3-D printing to create the first reactor that can continuously produce methanol from methane at room temperature and pressure. The team removed enzymes from methanotrophs, bacteria that eat methane, and mixed them with ...
