Sustainable High-Strength Proppants Derived from Waste Glass via Flame Spheroidization: Performance Evaluation and Fracture Conductivity Analysis.
Article in ACS omega, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hydraulic fracturing serves as an essential technology for the development of tight oil and gas resources, which creates substantial market demand for proppants. Conventional deep-fracturing ceramic proppants face bauxite resource shortages, requiring economical and sustainable substitutes. Massive annually produced waste glass suffers from low recycling and induces environmental hazards. Herein, material from waste glass (MFWG) are fabricated via the flame spheroidization. The as-prepared materials deliver crush resistance and fracture conductivity on a par with commercial high-performance ceramic proppants. Microscopic observations verify that MFWG feature near-perfect sphericity and smooth surfaces, which enables dense particle packing inside propped fractures. Further theoretical analysis reveals that such surface-governed dense packing regulates fracture conductivity by reducing bulk porosity and optimizing the geometric morphology and interconnection of internal pore channels. Overall, this work provides a sustainable, high-performance alternative that addresses both waste valorization and resource security.
