Ammonia is not only one of the most produced chemicals worldwide for fertilizer, but also a real carbon-neutral liquid fuel (CNLF), which is important for renewable energy storage and transportation. The well-known traditional Haber-Bosch (HB) process annually generates more than 120 million metric tons of ammonia for fertilizer, with about ~1.0% of the world’s annual energy consumpti ...

This proposal aims to develop a new, compact reactor for production of ammonia from air and water with renewable electricity. The conversion is carried out in a solid-state alkaline electrochemical cell at temperatures below 200oC and pressures below 10bar. Water vapor and N2 gas are fed into cathode side of the cell to form ammonia and hydroxide ions. As ammonia is produced from the cathode, the ...

There is growing interest in the use of ammonia as a clean alternative to fossil fuels. Ammonia belongs to a group of energy-dense liquid fuels that are much easier to store and transport than hydrogen. As ammonia decomposes to hydrogen through in a single reaction step and neither carbon oxide nor sulfur is involved in the product stream, ammonia is one of the most promising carbon neutral liquid ...

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 ...
