The composition of atmospheric particulate matter (“aerosols”) strongly influences health and environmental impacts, but there exist few time-resolved, long-term records of particle-phase chemical composition due to lack of appropriate monitoring tools. Needed is an instrument that is robust, easy-to-operate, with automated calibrations and data reduction, to provide operationally-inexpensive ...

"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 ...

To increase the utilization of electric vehicles, the US Department of Energy is seeking to reduce the cost of electric vehicle batteries to less than $125/kWh by 2022. To achieve this goal, the costs of cathode materials, which account for approximately 30% of the cost of vehicle batteries, must be reduced significantly. To address the challenge of lowering the costs of advanced lithium battery c ...

The feasibility for fusion as a practical energy source needs to be enhanced significantly by removing some of the restrictions that low-temperature superconductors put on the fusion magnet systems. This can be done by using high-temperature superconductors, allowing for much larger temperature margins, a higher magnet performance and less mechanical degradation during operation. There are curren ...

Bright coherent light sources in the soft x-ray region of the spectrum are useful for a variety of applications of interest to DOE in the basic sciences, nanoscience and biology, and for technological applications. At Free-Electron Laser Facilities, peak power output of the x-ray pulses is enhanced by using a mid-infrared laser pulse instead of a near-infrared pulse. The current front end for mid- ...
