Motivated by public hazards associated with contaminated sources of drinking water — such as Flint, Mich. and Newark, N.J. — a team of scientists has successfully developed and tested tiny, glowing crystals that can detect and trap heavy-metal toxins like mercury and lead.
A combination of experiments, including x-ray studies at Berkeley Lab, revealed new details about pesky deposits that can stop chemical reactions vital to fuel production and other processes. The study focused on deposits on HZSM-5, a common type of catalyst known as a zeolite that is used in biofuel production and in the refinery industry.
Lab researchers have published a new study in Science Advances that, for the first time, explicitly quantifies the thermodynamic scale of metastability for almost 30,000 known materials. This paves the way for designing and making promising next-generation materials for use in everything from semiconductors to pharmaceuticals to steels.
Researchers are working to dramatically increase the efficiency at which thin-film solar cells convert sunlight to electricity. Berkeley Lab scientists have taken a step towards that goal by developing a way to use optical microscopy to map thin-film solar cells in 3-D as they absorb photons.
Scientists have produced detailed 3-D visualizations that show an unexpected connectivity in the genetic material at the center of cells, providing a new understanding of a cell’s evolving architecture.
Berkeley and Illinois researchers have bumped up crop productivity by as much as 20 percent by increasing the expression of genes that result in more efficient use of light in photosynthesis. Their work could potentially be used to help address the world’s future food needs.
Every Nov. 11 the nation observes Veterans Day to pay respects to those who have served the country in the armed forces. Here we share the stories of two Lab veterans, Sandra Miarecki, who works in the Nuclear Science Division, and Chip Kozy, with the Engineering Division.
New findings suggest the rate at which atmospheric CO2 is accumulating has plateaued because Earth’s vegetation is grabbing more carbon from the air than in previous decades. That’s the conclusion of a new study based on extensive ground and atmospheric observations of CO2, satellite measurements of vegetation, and computer modeling.
Berkeley Lab scientists have, for the first time, achieved both lasing and anti-lasing in a single device. Their findings lay the groundwork for developing a new type of integrated device with the flexibility to operate as a laser, an amplifier, a modulator, and a detector.
In a new study, researchers shed light on a complex system of cell regulation that acts as a form of quality control for the transport of genetic information out of the nucleus. Getting a more complete picture of how genetic information gets expressed in cells is important in disease research, they say.
