This materials paper makes bismuth selenide nanosheets, evaporates them into thin films, and measures their thermoelectric properties for a small prototype generator. It contains no exposure or toxicity information for bismuth.
Key numbers
This paper reports no numerical findings relevant to bismuth exposure.
Methods (brief)
Hot-injection synthesis, vacuum thermal evaporation onto glass, post-fabrication heating, and measurement of conductivity and Seebeck coefficient (abstract).
Evidence fitness
This is a materials or analytical chemistry paper in which bismuth is a component of an engineered material. It does not support dietary exposure or toxicity claims for bismuth, and no bismuth was measured in food, water, feed, soil or human or animal tissue.
Limitations
Not relevant to food or health.
