Correction to “Slip Opacity and Fast Osmotic Transport of Hydrophobes at Aqueous Interfaces with Two-Dimensional Materials”

Abstract

In the discussion of the results presented in Figure 4c of the originally published article, an error was introduced in describing the range of the diffusio-osmotic coefficient. Specifically, the following sentence incorrectly states the range as −450 μm²/s to +450 μm²/s, whereas the correct range is −4900 μm²/s to +5300 μm²/s, as shown in Figure 4c: “Notably, graphene-coated systems exhibit the largest variation in diffusio-osmotic mobility, ranging from approximately −450 μm²/s for bilayer graphene with r = 2.25 Å to around 450 μm²/s for single-layer graphene with r = 1.5 Å”. For all systems except those where graphene is in direct contact with water (i.e., the top two-dimensional material) D_DO falls in a range between −1000 μm²/s and +1000 μm²/s. For systems where graphene is the top material instead, D_DO can reach values approximately between −5000 μm²/s and +5000 μm²/s, depending on the size of the hydrophobic solute, further stressing the influence of the large slip-length of graphene on D_DO, as opposed to systems where hBN or MoS₂ are the top materials. In the original article, we discuss our numerical results in the broader context of diffusio-osmotic transport experiments on other systems, in particular on silica which can be considered a model system for studies of diffusio-osmosis. For example, the range of values of D_DO reported in ref (1) (D_DO = −230 μm²/s) and ref (2) (D_DO = 200–800 μm²/s) is narrower than those on graphene-covered surfaces that we have investigated, highlighting the impact of slippage on diffusio-osmotic transport on graphene as opposed to a nonslipping surface such as silica. The conclusion of the manuscript regarding the influence of hydrophobes’ size and of the slip length on diffusio-osmotic transport is not altered by this correction, in fact we recognize that the slip-induced amplification of D_DO is more pronounced than what we have discussed previously. We apologize for the error and any confusion it may have caused. This article references 2 other publications. This article has not yet been cited by other publications.
