Tall towers and foundations for modern offshore and land-based wind turbines are too large to transport over roads or rail due to their extremely large dimensions. Existing “one-off” on-site construction methods are too expensive, and are too slow for manufacturing foundations and towers in the large numbers needed, especially for offshore components manufactured in ports with limited lay-down ...

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 ...

Quantifying atmospheric aerosol, clouds and precipitation processes are critical needs for understanding and interpreting Earth’s changing energy budget, is a DOE objective, and is of broader benefit to the public. Specifically, the formation of ice in the atmosphere depends on the nature and abundance of ice nucleating particles, and has major implications for precipitation and cloud interactio ...

The problem being addressed is the development of high intensity ultrashort pulse lasers, in recognition that today’s ultra-high intensity lasers are limited to repetition rates of < 10 Hz. Technical solutions are sought to enable the generation of high energy (joule-level) laser pulses that can be focused to highly relativistic intensity at high repetition rates (100-1000 Hz). The proposed proj ...

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 ...

Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is crucial to detect proliferation of nuclear material. Critical challenges include: (a) high sensitivity detection of signature emissions from radioactive isotopes, and (b) cost-effectiveness for deployment of sensor networks across large storage facil ...

Hypersonic missile defense systems are being designed to reach global threats. During flight, external surfaces are predicted to reach temperatures in excess of 2200C. As a result, innovative, high performance thermal protection systems (TPS) are of great demand. Among ultra-high temperature ceramics (UHTC), it is well known that ZrB2- and HfB2-based materials have high melting temperatures and ...

Separations often account for a majority of process costs. This is because all traditional separation processes have inherent weaknesses that prevent the system from achieving perfect (or even near perfect in many instances) selectivity. These weaknesses result in large recycle streams and require multiple separation units in concert in order to produce a product clean enough for use or sale. An a ...

Electrons play a very key role in plasma chemistry and dynamics of low temperature plasmas. Improved capability for measuring electron number density, ne, and electron energy distribution function, EEDF, in weakly ionized low temperature plasmas would benefit both fundamental study and application areas. For example, the capability would directly benefit emerging research targeted at modifying and ...

Development of Li-ion conducting membranes capable of supporting Li-metal anode to enable high- performance Li-metal batteries (LiMB) is a priority for the Department of Energy (DOE). State-of- the-art membranes used for Li-ion batteries (LiB) are not suitable for LiMB and have a number of disadvantages including poor cycling performance, low Li-ion conductivity, and electrochemical stability with ...
