New automotive engine technologies, such as direct injection with stratified charge combustion, are being explored under programs of the DOE and others that offer significant increases in efficiency and reductions in emissions. Research tools are needed to help determine how best to adequately control the combustion process throughout the engine operating envelope, to optimize combustion efficienc ...

Algae production in conjunction with wastewater treatment is a low-cost path to algae biofuels. Whole biomass is available for conversion to biofuel because algae biomass co-product sales are not required for good economics. Instead, added revenue is derived from wastewater treatment. Existing wastewater treatment pond facilities covering hundreds of acres are the only producers of microalgae ap ...

The Exascale Computing Project is tasked to develop the next generation of high performance computing systems capable of computing at 50 to 100 times faster than current HPC systems. Computing at this extreme-scale will significantly enhance the value of materials modeling and simulation to basic materials research and engineering In particular, computing at the extreme scale will enable a higher ...

Computer-aided Engineering software that apply the Finite Element Method to perform a multi-physics analysis have received widespread acceptance for traditional macro-scale material systems. Challenges persist in the modeling of complex coupled processes in environmental/thermal barrier coatings (E/TBCs) used to protect substrate material against the corrosive environment in the hot section parts ...

Metrology is a multi-billion dollar industry that is an indispensable part of science and manufacturing. A variety of techniques including interferometric microscopes, scanning electron microscopes (SEM), X-ray, and atomic force microscopes (AFM) are used in X-ray mirror manufacturing. The performance of any tool directly depends on the ability to characterize and tune it ...

Organic chemicals comprise the dominant fraction of particulates found in atmospheric aerosols, and the largest proportions of these are secondary products formed in the atmosphere from oxidation of volatile organic compounds. Often these chemical transformations result from complex pathways involving species from different sources. To understand these processes, we need to be able to trace the ...

Managing the flow of water, nutrients, and contaminants in watersheds is vital to addressing pressing issues related to water scarcity, access to clean drinking water, energy production, resilience to natural and anthropogenic perturbations, and ecological restoration. Decisions about the management of watersheds critically depend on the accuracy with which the flow of water and chemicals through ...

The objective of the proposed project is to develop the next generation of the low cost, high energy and high power solid state rechargeable lithium battery using a low cost enabling solid state electrolyte and protected lithium metal electrode developed by University of California in San Diego for use in the plug-in hybrid vehicle and electric vehicle. The advantages of the proposed solid state ...

A major problem with nuclear fission reactors is the welding of components of dissimilar metals, where the filler is usually of an additional metal alloy that is not necessarily the same as the two parts to be joined. Welding of metals will often have a heat affected zone (HAZ) and a thermo- mechanically affected zone (TMAZ), which need to be post-weld heat treated to minimize precipitation or seg ...

In order to make large scale commercial production of microalgae based commodity food and fuel products, significant strides in algal productivity need to be achieved. With current regulatory guidelines, large scale outdoor cultivation of microalgae for these products restricts the use of transgenic algal strains, which in the laboratory thus far have been the primary strategy taken to effectively ...
