JBEI Researchers Splice Corn Gene into Switchgrass, Increasing Plant Cell Wall Starch by 250%

December 7th, 2011|Categories: Energy, JBEI, News, Renewable Energy, Transportation Energy|Tags: , , , , , , |

Many experts believe that advanced biofuels made from cellulosic biomass are the most promising alternative to petroleum-based liquid fuels for a renewable, clean, green, domestic source of transportation energy. Nature, however, does not make it easy. Unlike the starch sugars in grains, the complex polysaccharides in the cellulose of plant cell walls are locked within a tough woody material called lignin. For advanced biofuels to be economically competitive, scientists must find inexpensive ways to [...]

E. Coli Bacteria Engineered to Eat Switchgrass and Make Transportation Fuels

December 7th, 2011|Categories: Energy, JBEI, News, Renewable Energy, Transportation Energy|Tags: , , , , , |

A milestone has been reached on the road to developing advanced biofuels that can replace gasoline, diesel, and jet fuels with a domestically produced clean, green, renewable alternative. Researchers with the U.S. Department of Energy's Joint BioEnergy Institute (JBEI) have engineered the first strains of Escherichia coli bacteria that can digest switchgrass biomass and synthesize its sugars into all three of those transportation fuels. What's more, the microbes are able to do this [...]

Sandia Study Shows Large LNG Fires Hotter but Smaller Than Expected

December 6th, 2011|Categories: Analysis, Energy Assurance, Infrastructure Security, Modeling, Modeling & Analysis, News, News & Events|Tags: , , , |

New research shows that large-scale liquefied natural gas fires are hotter but smaller than anticipated, which means regulators can assume that a slightly smaller area would be at risk in the case of an LNG incident, an official from Sandia National Laboratory said Sunday at a meeting of the National Association of Regulatory Utility Commissioners. However, the study showed that extreme cold from spilling LNG combined with extreme heat from an LNG fire [...]

Researchers at the Wind Energy Manufacturing Laboratory—a joint effort of researchers from TPI Composites, a Scottsdale, Arizona-based company that operates a turbine blade factory in Newton, and Sandia National Laboratories, and located at Iowa State University—used laser readings to calculate how dozens of the layers would fit and flow over the curves of a mold used to manufacture a blade. If there was a wrinkle or wave in the fabric, any defect at [...]

From Compost to Sustainable Fuels: Heat-Loving Fungi Are Sequenced

November 10th, 2011|Categories: Energy, Modeling, Modeling & Analysis, News, Renewable Energy, Transportation Energy|Tags: , , , |

Two heat-loving fungi, often found in composts that self-ignite without flame or spark, could soon have new vocations. The complete genetic makeup of Myceliophthora thermophi­la and Thielavia terrestris has been decoded by an international group of scientists. The findings, published in Nature Biotechnology, may lead to the faster and greener development of biomass-based fuels, chemicals, and other industrial materials. In sequencing M. thermophila and T. terrestris, the research team also discovered that both [...]

June 27-28, 2011 [singlepic id=979 w=320 h=240 float=right] The rebound (or take-back) effect) is the term in energy economics used to describe the effectin which increases in energy efficiency do not necessarily lead to simple 1:1 decreases in energy consumption, but instead are “taken back” in the form of higher consumption of the goods and services that the energy is used to create. Although taken very seriously in Europe, both in academia and in policy circles, [...]

Four-color laser white illuminant demonstrating high color-rendering quality

August 15th, 2011|Categories: News, Solid-State Lighting|Tags: , , , , , , , |

July 4, 2011 [singlepic id=980 w=320 h=240 float=right]Solid-state lighting is currently based on light-emitting diodes (LEDs) and phosphors.  Solid-state lighting based on lasers would offer significant advantages including high potential efficiencies at high current densities. Light emitted from lasers, however, has a much narrower spectral linewidth than light emitted from LEDs or phosphors.  Therefore it is a common belief that white light produced by a set of lasers of different colors would not be of [...]
