Immobilization of cadmium and zinc in soil by Al-montmorillonite and gravel sludge
, 1998 We investigated the potential of montmorillonite, Al‐montmorillonite and gravel sludge to immobilize polluting heavy metals in agricultural soil. Batch experiments showed that both Al‐montmorillonite and montmorillonite immobilized zinc and cadmium. Zinc

Water‐based drilling fluids formulated with mature fine tailings
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Mature fine tailings (MFT) are persistent, highly stable colloidal suspensions generated as byproducts of bitumen extraction from oil sands. Given their environmental risks, identifying viable applications for MFT could reduce their accumulation while offsetting natural resource use.

Deep Underground Science and Engineering, EarlyView.Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of
