High strength, oxidation resistant refractory alloys are difficult to fabricate for commercial use in extreme environments.
Commercial closed-cell insulation foam boards reduce their thermal resistivity by up to 30% due to gas diffusion in and out of foam cells.
Most plastic is discarded after a single use, with about 76 percent of plastic waste discarded into landfills annually. The current practice is wasting feedstock resources, energy, and carbon used for their production.
Technetium is a radioactive isotope that is a byproduct of nuclear processing; there are currently limited mechanisms to capture technetium when uranium is recycled, hindering the efficient recycling of spent nuclear fuel.
Adhesives for metal parts typically are liquid-based which require complex processing. This technology is a hot melt adhesive that is mixed and applied in a solid form and after the heating and cooling cycle creates strong bonds with the substrates in a matter of seconds.
High and ultra-high vacuum applications require seals that do not allow leaks. O-rings can break down over time, due to aging and exposure to radiation. Metallic seals can damage sealing surfaces, making replacement of the original seal very difficult.
The co-processing of cathode and composite electrolyte for solid state polymer batteries has been developed. A traditional uncalendared cathode of e.g.
The first wall and blanket of a fusion energy reactor must maintain structural integrity and performance over long operational periods under neutron irradiation and minimize long-lived radioactive waste.
