US nuclear fusion breakthrough: Solid materials found to elevate low-energy reaction rates

Researchers at UC Davis and Lawrence Berkeley National Laboratory found that titanium and palladium foils loaded with deuterium can greatly boost low-energy fusion rates.

The enhancement can reach about 10^18 times the rate seen without surrounding metal, then levels off below expected thresholds.

The result suggests solid host materials can be engineered to influence fusion reactions, improving neutron source design and fusion-material models.

The work also highlights the role of electron shielding and AI-based modeling tools such as DuctGPT in understanding these effects.
