Waders in a sea of debris: a global overview

Biological Reviews, EarlyView.
ABSTRACT The impact of plastic pollution on ecosystems and marine fauna is well documented, although research into its effects on waders (also known as shorebirds) remains limited. Given that waders are exposed to coastal marine litter, this exposure could be a significant factor in the decline of their populations. This study aims to assess the global

Natural South African iron‐rich sand as a functional catalyst in hybrid photocatalytic wet peroxide oxidation technology for the degradation of methyl orange dye pollutant

The Canadian Journal of Chemical Engineering, EarlyView.
This research explored South African iron‐rich sand (SAIRS) as a natural catalyst for light‐mediated wet peroxide oxidation of methyl orange dye in wastewater and at an optimized of conditions of 3500 mg/L catalyst dose, 6 mM H2O2, and pH 2.5, SAIRS achieved 94% methyl orange degradation within 90 min under visible light.

Safety soft sensor development for pilot‐scale ilmenite electric arc furnace using long short‐term memory‐based architecture

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Ilmenite electric arc furnaces (EAFs) are used for smelting titanium‐iron oxide ore at high temperatures generated by electrical arcs to produce titanium slag and pig iron. As these units are pushed to their limits, ensuring safe and reliable operation becomes challenging.

Temperature‐dependent shear behavior and constitutive model of the rock–concrete interface

Deep Underground Science and Engineering, EarlyView.
Shear tests were conducted to investigate the temperature‐dependent shear behavior of the rock–concrete interface, highlighting the interaction between the surrounding rock and the lining during tunnel fires. Under experimental conditions, concrete exhibited greater temperature sensitivity than rock, with the shear fracture surface transitioning from ...
