The feasibility of fusion as a practical energy source needs to be improved significantly by removing some of the restrictions that low-temperature superconductors put on the fusion magnet systems. One method to simplify the magnet system is by using high-temperature superconductors that allow for more compact magnet systems with higher performance and much larger temperature margins. The compact, ...

The simulation of magnetically confined plasmas requires consideration of multiple overlapping scales. Continuum models address reactor scale behaviors, while particle methods capture fine scale behavior. The complex combination of physics and reactor geometry results in simulations involving massive calculations and data sets, which can only be executed on parallel computers. Thus, there is a cri ...

Cellulose nanofibrils represent a natural, sustainable source of nanofibers that can be used as reinforcing additives. Unfortunately, the hydrophilic surface properties of the cellulose nanofibrils make it difficult for them to be incorporated into hydrophobic polymer matrices of common manufacturing plastics to form fiber reinforced composites. TDA is developing technology that can be used to mod ...

A recent experiment at the DIII-D tokamak has pioneered an innovative and potentially critical actuator for burning plasmas: helicon wave current drive. Steady-state profile maintenance in future burning plasma experiments will require efficient and economically viable sources of off-axis current drive. Promising indications that helicon current drive can fill this need led to the establishment of ...

OLED lighting panels have been available commercially for several years, with relatively slow adoption into commercial and consumer fixtures in the US. This project addresses both channels through the commercialization of an ultra-thin, bendable, high-efficacy OLED light engine in which a panel and driver are engineered together in one low-cost, easy-to-use package. The most significant benefit of ...

Laser plasma accelerators (LPA) enabled by the Tm laser driver to be developed by this project offer much reduced size and cost compared to conventional accelerators of the same energy. This would drastically cut the cost of highenergy particle research on collider-based facilities and advanced light sources. Planned conventional accelerators (e.g., for the proposed International Linear Collider) ...

Nano materials have a wide range of applications, ranging from drug delivery in medical applications to new composite materials in aerospace applications. Experimental data on nanoparticle growth exists, but numerical simulations are needed to understand the underlying physical mechanisms and to enable better prediction of nanomaterial production. The numerical models of plasma assisted production ...

The Department of Energy is soliciting an emergency hydrogen refueler for an individual consumer fuel cell vehicle. With sparse hydrogen filling stations at present, operators of fuel cell powered vehicles can experience range anxiety lessening the appeal of these vehicles. Skyhaven Systems, LLC is developing an emergency hydrogen refueler that can be stored in the vehicle trunk and used by the co ...

Seawater contains about 3 parts per billion of uranium. With a total ocean volume of approximately 1.3109 km3, there is at least 4.5 billion tons of uranium in seawater which is about 1000 times the amount of uranium known to exist in terrestrial ores. Mining uranium from seawater is economically feasibility if an efficient, reusable and low-cost adsorbent could be developed. In the past year, ...

The Industrial Internet of Things (IoT) is growing rapidly and is creating the need for a more decentralized and secure way to integrate (IoT) devices into Smartgrid and power plant control system infrastructure. With an estimated 212 Billion sensor-enabled IoT devices to be deployed by 20201, these internet-connected devices will need to be managed differently than the current centralized approac ...
