Curvature Determination of Spinodal Interface in a Condensed Matter System
Abstract
Laser scanning confocal microscopy has been used to study the time evolution of a three dimensional spatially bicontinuous structure of a phase-separated polymer blend undergoing the late stage of spinodal decomposition, as a model example of condensed matter systems. Both the mean and Gaussian curvatures of the interface between two coexisting phases have been directly measured for the first time from the reconstructed 3D image. The Gaussian curvature is negative, clearly demonstrating that the interface of the bicontinuous structure is anticlastic, while the mean curvature is close to zero. Self-similar growth of the structure is inferred from the time evolution of the average radius of curvature of the interface.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
