A cold-spray chamber is shown during deposition
// Recognition
LLNL and TTEC Thermoelectric Technologies have won an R&D 100 award for developing a new technique called Versatile Cold Spray.
Four scientists, head shots
// Recognition
Four Lawrence Livermore National Laboratory (LLNL) scientists have been selected as 2020 fellows of the American Physical Society (APS).
Ben Santer
// Recognition
Renowned Livermore atmospheric scientist Ben Santer has been honored with the American Geophysical Union’s 2020 Bert Bolin Award.
Composite of electron microscope image and simulation
// S&T Highlights
An LLNL team solved a mystery of metallurgy by simulating the metal hardening process.
methane hydrate electron microscope image
// S&T Highlights
A multi-institutional research team synthesized methane hydrate with sediments to determine the electrical conductivity of the mixtures.
Elephant Toothpaste Demonstration
// Fun with Science
In this experiment, “elephant toothpaste” is made by the decomposition of hydrogen peroxide using a catalyst to facilitate an otherwise invisible chemical reaction. H202 is decomposed in a graduated cylinder by adding a scoop of potassium iodide. Soap is added to make the mixture foam and food coloring is used to add color and the effect of foaming toothpaste.
Cryogen Crunch Demo
// Fun with Science
Experiments with ultra-cold liquid nitrogen demonstrate states of matter, such as solids, liquids and gases, and phase transitions between these states using everyday items. A large CO2 balloon is compressed inside a tiny beaker by freezing the gas into dry ice. Then, a fluffy marshmallow is submerged in liquid nitrogen and shattered into tiny pieces.
An artist’s view of small-diameter carbon nanotubes that pass through water molecules (red and white) and reject ions (blue)
// S&T Highlights
Livermore researchers have created carbon nanotube pores that are so efficient at removing salt from water they are comparable to commercial desalination membranes.
Félicie Albert
// Recognition
Staff Scientist Félicie Albert has been elected a Kavli Fellow of the U.S. National Academy of Sciences.
