The exclusion zone grows over time in a way that matches what would be expected from diffusion processes, supporting the theory that concentration differences drive this phenomenon.
Scientific Claim
The growth of the exclusion zone with time follows a power law with an exponent of approximately 0.6, which is consistent with diffusion-driven processes as predicted by diffusiophoresis theory.

Assessment Explanation
The study reports a specific quantitative observation (exponent of 0.6) from Huszár et al., which is a factual statement about experimental findings.
Source Excerpt
“Huszár et al. note that the growth of the exclusion zone with times follows a power law with an exponent of 0.6, very close to the exponent of 0.5 expected for a diffusion-driven process.”
Evidence from Studies
Supporting Evidence (1)
The study reports that Huszár et al. observed the growth of the EZ follows a power law with exponent 0.6, which is close to the 0.5 expected for diffusion-driven processes, supporting diffusiophoresis theory.
