Auto-segmentation technique for SEM images using machine learning: Asphaltene deposition case study.

Enormous efforts have been attempted to replace the subjective human analysis of digital images by automated computational methods such as image processing and computer vision. The image processing methods (i.e.

Structure of Asphaltenes during Precipitation Investigated by Ultra-Small-Angle X-ray Scattering.

Time-resolved size and structure measurements of asphaltenes while in the process of precipitating were monitored for the first time using ultra-small-angle X-ray scattering. The results revealed that asphaltenes precipitating from a heptane-toluene mixture demonstrate a hierarchical structure of an asphaltene-rich phase (e.g.
