A study on chemical stabilization of Oil Sands Mature Fine Tailings
… difficult and time-consuming. In this thesis, chemical stabilization of MFT is investigated in an experimental program. Portland cement (PC) and two liquid-based silicate grouts (NS and AAAS) are used for stabilization of MFT. The effectiveness of these stabilizers at different dosages and …

The performance of cross-linked acellular arterial scaffolds as vascular grafts; pre-clinical testing in direct and isolation loop circulatory models
… calcify after implantation. We hypothesized that chemical stabilization of acellular xenogenic arteries would generate off-the-shelf grafts resistant to thrombosis, dilatation and calcification. To test this hypothesis, we decellularized porcine renal arteries, stabilized elastin with pentagalloyl …

Development of Carbon-Based, Controlled-Release Soil Ameliorants Through Chemical Pathways
… controlled-release fertilizers (CBCRFs) through chemical carbonization followed by nutrient impregnation. The process involved treating lignocellulosic biomass with 93% sulfuric acid to produce a stable carbon matrix, subsequently neutralized with anhydrous ammonia to incorporate nitrogen. In …

Sustainable advancements in rural infrastructure: Enhancing gravel road performance, stabilization, and intelligent monitoring
… context that combines predictive modeling, chemical stabilization, and a framework proposing an AI-driven monitoring approach to enhance gravel road performance and longevity.The first study establishes a predictive model for dust generation, correlating vehicle speed (25–50 mph) and surface …

Chemical Controls on the Formation of Amorphous and Crystalline Calcium Phosphates
… brushite shortly after reagent mixing, without chemical stabilization. This method was used in the second project to examine how the initial Ca/P affects ACP structure and transformation. Our results identify the first structural differences in types of ACP, controlled by the initial Ca/P. At …

Synergistic and Environmental Benefits of Using Cement Kiln Dust With Slag and Fly Ash in Cemented Paste Tailings
… through the hardened matrices. Meticulous geochemical characterization of cemented paste tailings formulations is imperative, particularly when binders replace the traditional Portland cement. The leaching behavior of metals in cemented paste tailings formulations was studied using field …

Stabilised decellularised vascular grafts in an ovine carotid model
… investigated as alternative conduits, but this chemical treatment results in degradation of the extracellular matrix. Chemical stabilization of elastin with penta-galloyl glucose (PGG) combined with collagen stabilisation during covalent heparinisation was previously investigated by our group in …

Cement Stabilization of Aggregate Base Materials Blended with Reclaimed Asphalt Pavement
The purpose of this research was to investigate the effects of reclaimed asphalt pavement (RAP) content and cement content on the strength and durability of recycled aggregate base materials. Specifically, the unconfined compressive strength (UCS) and final dielectric value in the Tube Suction Test …
