Geochemical and microbiological variability of aerobic and anaerobic sediments along a bifurcated sulphate‐saturated brine spring in western Canada

The Depositional Record, Volume 10, Issue 5, Page 637-669, November 2024.
A tufa mound developed in north‐east Alberta is characterised by an unusual emplacement of a gypsum caprock. This two‐tiered architecture resulted from the bicarbonate‐saturated groundwater flow along Upper Devonian limestone being redirected deeper and encountering the halite–anhydrite dissolution trend within the underlying Prairie Evaporite ...

Insight into the critical evaluation indicators for fatigue performance recovery of rejuvenated bitumen under different rejuvenation conditions

International Journal of Fatigue, 2023
This study aims to propose critical fatigue indicators for evaluating the restoration effectiveness of various rejuvenators on the fatigue performance of aged bitumen. The influence factors of rejuvenator type/dosage and aging degree of bitumen are involved, and different fatigue parameters from linear viscoelastic (LVE), linear amplitude sweep (LAS ...

Feasibility of using phytoremediation biomass for sustainable biofuel production via thermochemical conversion

Biofuels, Bioproducts and Biorefining, Volume 18, Issue 4, Page 1010-1026, July/August 2024.
Abstract This study explores a novel approach that combines soil recovery with biofuel production, presenting a strategy that addresses the increasing demand for biofuels while sidestepping the food–fuel debate. It also introduces an innovative method for recovering heavy metals from soils through their translocation into the solid product of the ...
