Researchers Probe Into Electronic Structure Of Metal-organic Framework
2013-11-22 12:39:00

Lawrence Berkeley National Laboratory A unique inside look at the electronic structure of a highly touted metal-organic framework (MOF) as it is adsorbing carbon dioxide gas should help in the design of new and improved MOFs for carbon capture and storage. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have recorded the first in situ electronic structure observations of the adsorption of carbon dioxide inside Mg-MOF-74, an open...

Study Reveals Origins Of An Exotic Phase Of Matter
2013-11-19 06:34:34

Lawrence Berkeley National Laboratory Understanding superconductivity – whereby certain materials can conduct electricity without any loss of energy – has proved to be one of the most persistent problems in modern physics. Scientists have struggled for decades to develop a cohesive theory of superconductivity, largely spurred by the game-changing prospect of creating a superconductor that works at room temperature, but it has proved to be a tremendous tangle of complex physics. Now...

Lignin-Feasting Microbe Could Be Used For Biofuels
2013-11-13 16:08:10

Lawrence Berkeley National Laboratory Nature designed lignin, the tough woody polymer in the walls of plant cells, to bind and protect the cellulose sugars that plants use for energy. For this reason, lignin is a major challenge for those who would extract those same plant sugars and use them to make advanced biofuels. As part of their search for economic ways to overcome the lignin challenge, researchers at the Joint BioEnergy Institute (JBEI) have characterized the enzymatic activity of...

Researchers Develop Technique For Imaging Individual Carbon Nanotubes
2013-11-13 07:50:55

Lawrence Berkeley National Laboratory Despite their almost incomprehensibly small size – a diameter about one ten-thousandth the thickness of a human hair – single-walled carbon nanotubes come in a plethora of different “species,” each with its own structure and unique combination of electronic and optical properties. Characterizing the structure and properties of an individual carbon nanotube has involved a lot of guesswork – until now. Researchers with the U.S. Department of...

Detailed Look At A DNA Repair Protein In Action
2013-10-24 07:07:42

Lawrence Berkeley National Laboratory Provides New Insight into Genome Integrity and Biological Detection of Mismatched DNA Errors in the human genetic code that arise from mismatched nucleotide base pairs in the DNA double helix can lead to cancer and other disorders. In microbes, such errors provide the basis for adaption to environmental stress. As one of the first responders to these genetic errors, a small protein called MutS – for “Mutator S” – controls the integrity of...

Method Developed To Make Hydrogen Fuel From Sunlight
2013-08-29 15:41:47

Lawrence Berkeley National Laboratory Berkeley Lab Researchers at Joint Center for Artificial Photosynthesis Make Unique Semiconductor/Catalyst Construct In the search for clean, green sustainable energy sources to meet human needs for generations to come, perhaps no technology matches the ultimate potential of artificial photosynthesis. Bionic leaves that could produce energy-dense fuels from nothing more than sunlight, water and atmosphere-warming carbon dioxide, with no byproducts...

Finding comes from new Berkeley Lab study Lawrence Berkeley National Laboratory (Berkeley Lab) analyzed more than 50,000 home sales near 67 wind facilities in 27 counties across nine U.S. states, yet was unable to uncover any impacts to nearby home property values. "This is the second of two major studies we have conducted on this topic [the first was published in 2009, see below], and in both studies [using two different datasets] we find no statistical evidence that operating wind...

Size Matters When Nanocrystals Go Through Phases
2013-08-26 15:35:09

Lawrence Berkeley National Laboratory Berkeley Lab Researchers at the Molecular Foundry Reveal Fundamental Size-Dependence of Metal Nanocrystals Undergoing Phase Transitions Understanding what happens to a material as it undergoes phase transformations – changes from a solid to a liquid to a gas or a plasma – is of fundamental scientific interest and critical for optimizing commercial applications. For metal nanocrystals, assumptions about the size-dependence of phase...

Research Could Help Scientists Predict How Carbon Is Stored Underground
2013-08-23 05:49:36

Lawrence Berkeley National Laboratory Computer simulations conducted at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) could help scientists make sense of a recently observed and puzzling wrinkle in one of nature’s most important chemical processes. It turns out that calcium carbonate—the ubiquitous compound that is a major component of seashells, limestone, concrete, antacids and myriad other naturally and industrially produced substances—may...

Researchers Discover A Tiny Twist In Bilayer Graphene That May Solve A Mystery
2013-08-12 16:36:44

Lawrence Berkeley National Laboratory Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a unique new twist to the story of graphene, sheets of pure carbon just one atom thick, and in the process appear to have solved a mystery that has held back device development. Electrons can race through graphene at nearly the speed of light – 100 times faster than they move through silicon. In addition to being superthin...
