Rapid Building Energy Modeler: The Key to Fast Energy Efficiency

Wednesday, April 23rd, 2014

A multi-billion dollar market exists for reducing the energy use of existing buildings, if scientists can only figure out a way to substantially reduce the cost and time required to assess building energy performance, recommend energy performance measures, and identify problems in building operations. This is the goal of RAPMOD, the Rapid Building Energy Modeler, a collaborative project involving UC Berkeley, Berkeley Lab, and engineers at Baumann Consulting. More>

First Size-based Chromatography Technique for the Study of Living Cells

Tuesday, April 22nd, 2014

Jay Groves of the Physical Biosciences Division led the development of the first size-based form of chromatography that can be used to study the membranes of living cells. This unique physical approach to probing cellular membrane structures, which is based on nanodot technology, can reveal information critical to whether a cell lives or dies, remains normal or turns cancerous, that can’t be obtained through conventional microscopy. Working with Groves on this project were Niña Caculitan, Hiroyuki Kai, Eulanca Liu, Nicole Fay, Yan Yu, Theobald Lohmüller and Geoff O’Donoghue. More>

Lab Programs Enable Ebola Virus Research

Friday, April 18th, 2014

The Ebola outbreak in West Africa has claimed over 110 lives and more than 170 cases have been reported. While there is no known cure for the virus, basic research is providing insight into the viral mechanism. Recently, a team led by Erica Ollman Saphire (Scripps) elucidated one of the structures of an Ebola virus protein VP40 using data collected in the Berkeley Center for Structural Biology at the Advanced Light Source. Further studies illustrate how VP40 assumes various structural conformations to enable different functions. All structures were solved using PHENIX, automated crystallography software developed under the direction of Paul Adams in the Physical Biosciences Division. More>

Lab Scientists are Leading Contributors to Latest IPCC Assessment

Tuesday, April 15th, 2014

The bad news: a major transformation of our current energy supply system is needed in order to avoid a dangerous increase in global temperatures. The good news: the technologies needed to get there are mostly readily available. These are some of the main conclusions reached by Berkeley Lab experts and their Working Group III co-authors on the Fifth Assessment Report of the U.N. Intergovernmental Panel on Climate Change (IPCC). Lab contributors included Jayant Sathaye, Ryan Wiser, Ashok Gadgil, Lynn Price, James McMahon, Ali Hasanbeigi, and Stephane de la Rue Du Can, all of the Environmental Energy Technologies Division.

EERE’s David Danielson Visits Lab to Help Launch FLEXLAB Research Project

Tuesday, April 15th, 2014

David Danielson, Assistant DOE Secretary for Energy Efficiency and Renewable Energy, visited the Lab Monday to tour FLEXLAB, the Facility for Low-Energy experiments in Buildings, and to meet with executives of Webcor. The construction firm is partnering with FLEXLAB to test building energy performance for a new building for Genentech. The research will take place in FLEXLAB’s rotating testbed, a unit that rotates 270 degrees to allow the study of building energy use in a variety of orientations relative to the sun. Danielson also met with Lab researchers and Lab Director Paul Alivisatos and toured the Molecular Foundry.

Novel Way to Make Ethanol Without Corn or Other Plants

Monday, April 14th, 2014

ncem imageStanford University scientists, with help from Jim Ciston at Berkeley Lab’s National Center for Electron Microscopy, have found a new, highly efficient way to produce liquid ethanol from carbon monoxide gas. This promising discovery could provide an eco-friendly alternative to conventional ethanol production from corn and other crops, say the scientists. Their results are published in the April 9 advanced online edition of the journal Nature. Go here to read a Stanford University news release on the research.

UC Berkeley College of Chemistry Launches Research Hub

Vehicle to Grid Simulator Will Help Harness EVs

Friday, April 11th, 2014

EV imageV2G Sim, a vehicle-to-grid simulation program developed by EETD researchers, will help government authorities, power markets, entrepreneurs, and other stakeholders harness the resource offered by the growing fleet of plug-in electric vehicles (PEVs). The PEV fleet can be used to avoid potential shortages of electricity during peak times, and provide extra storage capacity when the grid is generating more than it needs to satisfy demand. Learn more about the research here.

ALS Capabilities Reveal How Like Can Attract Like

Friday, April 11th, 2014

story imageBerkeley Lab researchers working at the ALS have observed an unusual pairing that seems to go against a universal scientific truth–that opposite charges attract and like charges repel. The researchers demonstrated that, when hydrated in water, positively charged ions (cations) can actually pair up with one another. Read more…

BOSS Quasars Measure Universal Expansion Rate With Highest Precision

Tuesday, April 8th, 2014

The Baryon Oscillation Spectroscopic Survey (BOSS), part of the third Sloan Digital Sky Survey, pioneered quasar studies of dark energy. Andreu Font-Ribera of the Physics Division has led a new kind of quasar analytical method. Combined with older methods, it establishes the universe’s expansion rate at redshift 2.34 within two percent: 68 kilometers per second per million light years, the most precise measurement of expansion since galaxies formed. BOSS PI David Schlegel remarks that when the technique was first suggested, “some of us were afraid it wouldn’t work,” but “our precision measures are even better than we optimistically hoped for.” More>
