Researchers at the Department of Energy’s Lawrence Berkeley National Lab (Berkeley Lab) and the University of Hawaii have uncovered the first step in the process that transforms gas-phase molecules into solid particles like soot and other carbon-based compounds.

Shapes of Things to Come: Exotic Shapes for Liquid Drops Have Many Possible Uses

Through a combination of water, oil and nanoparticle surfactants plus an external field, spherical droplets are being transformed into ellipsoids and other unusual shapes that could find many valuable uses.

3D Dynamic Imaging of Soft Materials

Through a combination of transmission electron microscopy (TEM) and a unique graphene liquid cell, Berkeley Lab researchers have recorded the three-dimensional motion of DNA connected to gold nanocrystals, the first reported use of TEM for 3D dynamic imaging of soft materials.

One-Pot to Prep Biomass for Biofuels:

Joint BioEnergy Institute (JBEI) researchers save water and reduce pollution with the first one-pot, wash-free, process for the ionic liquid pretreatment and saccharification of switchgrass, one of the leading biofuel feedstock candidates.

A Path to Better MTV-MOFs:

A team of Berkeley Lab and UC Berkeley researchers have developed a method for accurately predicting the ability of MTV-MOFs (multivariate metal organic frameworks) to scrub carbon dioxide from the exhaust gases of fossil fuel power plants.

Speeding the Search for Better Methane Capture

Systematic in silico studies have identified several zeolite compounds that show technological promise for capturing methane, the main component of natural gas that can serve as an ally or an adversary in combating global climate change.

In the Blink of an Eye: X-ray Imaging on the Attosecond Timescale

In the blink of an eye, more attoseconds have expired than the age of Earth measured in – minutes. A lot more. To be precise, an attosecond is one billionth of a billionth of a second. The attosecond timescale is where you must go to study the electron action that is the starting point of

Searching for the Solar System’s Chemical Recipe

The ratio of isotopes in elements like oxygen, sulfur, and nitrogen were once thought to be much the same everywhere, determined only by their different masses. Then isotope ratios in meteorites, interplanetary dust and gas, and the sun itself were found to differ from those on Earth. Planetary researchers now use Berkeley Lab’s Advanced Light Source to study these “mass-independent” effects and their origins in the chemical processes of the early solar system.

Forcing the Molecular Bond Issue

Researchers at Berkeley Lab’s Molecular Foundry developed a first-of-its-kind model for providing a comprehensive description of the way in which molecular bonds form and rupture. This model enables researchers to predict the “binding free energy” of a given molecular system, a key to predicting how that molecule will interact with other molecules.

Four Berkeley Lab Researchers Named to National Academy of Sciences

Bernard Sadoulet

Four Lawrence Berkeley National Laboratory (Berkeley Lab) researchers were elected members or foreign associates to the National Academy of Sciences (NAS), today. The four make up a class of 84 new members and 21 foreign associates this year. The election recognizes their distinguished careers and research achievements. The NAS membership is one of the highest
