You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: In earlier work , Duff et al . 18 formed U(VI)-containing hematite via a coprecipitation method at pH 11 and interpreted their EXAFS as showing incorporation of uranium into the crystal structure , with an oxygen coordination of approximately 4 at radial distances of 2.19 Å ( N = 1.4 ± 15 % ) and 2.36 Å ( N = 2.1 ± 20 % ) , with a single Fe atom ( N = 1.12 ± 25 % ) at a distance of 3.19 Å. The implication is that uranium was incorporated into hematite with the loss of the axial UO bonds . Latterly , it has been suggested that the Duff model had an unexpectedly low UO coordination , suggesting that not all of the UO bond distances were fully resolved from the EXAFS . 20 The same approach to uranium incorporation into hematite was followed by Ilton et al . 19 who reported a similar uranium environment to Duff et al . 18 Our EXAFS data analysis showed that these models are incorrect and that U(VI ) is fully coordinated by 6 oxygens within a distorted octahedral site in the hematite structure .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
