Abstract
Surface quality is key for any adsorbent to have an effective adsorption. Because analyzing an adsorbent can be costly, we established an imagery protocol to determine adsorption robustly yet simply. To validate our hypothesis of whether stereomicroscopy, superpixel segmentation and fractal theory consist of an exceptional merger for high-throughput predictive analytics, we developed carbon-capturing biointerfaces by pelletizing hydrochars of sugarcane bagasse, pinewood sawdust, peanut pod hull, wheat straw, and peaty compost. The apochromatic stereomicroscopy captured outstanding micrographs of biointerfaces. Hence, it enabled the segmenting algorithm to distinguish between rough and smooth microstructural stresses by chromatic similarity and topological proximity. The box-counting algorithm then adequately determined the fractal dimension of microcracks, merely as a result of processing segments of the image, without any computational unfeasibility. The larger the fractal pattern, the more loss of functional gas-binding sites, namely N and S, and thus the potential sorption significantly decreases from 10.85 to 7.20 mmol CO2 g−1 at sigmoid Gompertz function. Our insights into analyzing fractal carbon-capturing biointerfaces provide forward knowledge of particular relevance to progress in the field’s prominence in bringing high-throughput methods into implementation to study adsorption towards upgrading carbon capture and storage (CCS) and carbon capture and utilization (CCU).

The IPPC’s experts estimate the Earth's surface temperature at 2 ◦ C above the preindustrial baseline (1850–1900) by 2100
The SLIC algorithm segmented the micrographs into k-connected superpixels merely as a result of processing low-intensity regions in the image by color similarity and topological proximity
The outputs of BCM are accurate inputs to describe on sigmoid Gompertz function the dynamics between fractality and adsorbent’s overall quality
Summary
The IPPC’s experts estimate the Earth's surface temperature at 2 ◦ C above the preindustrial baseline (1850–1900) by 2100. The literature focuses on absorption [2,3,4], adsorption, cryogenic distillation [5], and separation [6]. The adsorption works on the simplest physical principles of capturing and binding an adsorbate in pores and functional sites on the surface of the material [7]. Adsorption, relative to absorption on amine-containing solutions, is not energy-intensive and other immediate advantages refer to compactness and conservation of space, and a wider range of suitable scaffoldings and powders to assemble resilient sorbents [8]. The application of carbon-capturing materials is common in coal-firing and gas-firing power stations across the USA, UK and European Union. They can potentially prevent the industry from emitting about 10,000.00 Mt
