Colloidal perovskite quantum dots (QDs) or nanocrystals (NCs) with structure of CsPbX3 (X = Cl, Br, I) are promising materials as down-converting phosphors due to their high quantum yield up to >90%, extremely narrow emission band ~15-30 nm, and tunable emission wavelengths of ~410−700 nm via size or composition control. Compared to other QD materials, the optical and electronic properties of pe ...

By 2025, 1.8 billion people will be living in places with severe water scarcity and two-thirds of the global population will encounter some degree of water stress. If warming continues at the current pace, by 2030 half of the world’s population will experience severe water stress (Runte 2016). The demands are strong; the restraints, on the other hand, come from (1) high capital investment for eq ...

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 ...

Currently the chemical composition of atmospheric particulate matter is measured either by off-line analyses of time-integrated filter samples, or by in-situ instruments requiring near-constant operator oversight. These measurement approaches result in sparse or limited data coverage. Despite the critical role of composition on the health and environmental impacts of particulate matter, there exis ...

Accurate simulation of nuclear power plant behavior is necessary for both engineering and training applications. An engineering grade simulator, used for design, safety analysis and operations, is characterized by high fidelity, computational power, lack of real-time capability, and user non-interactive environment. By contrast, a training grade simulator, used for operator training and education, ...

Sn-doped In2O3 (ITO) is the industry standard and most widely used transparent conducting electrode (TCE) because of its good electrical and optical properties. However, ITO has a number of disadvantages: ITO is not a suitable TCE for next-generation, high-efficiency, flexible OLEDs, because of its inappropriate work function, difficulty in creating desired patterns, low stability, delaminantion d ...

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 ...

Establish means and methods to perform comprehensive mechanical characterization using miniature tensile specimens for highly irradiated materials. The solution should aid in dramatic reduction of irradiated material waste and provide feasibility for easy incorporation and remote operation within hot cell environments. Based on previous research, an Advanced Mechanical Test (AMT) test bed incorpor ...

Increased productivity of wind turbines and wind plants requires a better understanding of the unsteady blade aerodynamics.This understanding could lead to improved energy capture and reduced blade loading and to a better understanding of wake development and propagation that promises to increase the overall production of a wind plant. Unsteady pressure measurements on the surface of the blades of ...

"The next generation of very high field accelerator magnets (20 T or more) are expected to be made with high-temperature superconductors (HTS) along with conventional low-temperature superconductors (LTS) to reduce cost. The operation and protection of these magnets becomes very challenging particularly if the HTS coils are made with the tapes and operate at a much lower current than the LTS coils ...
