Hydrogen donor‐assisted visbreaking of Canadian oil sands bitumen

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract High‐viscosity Canadian oil sands bitumen requires processing for efficient transportation and refining. Partial upgrading technologies, primarily based on thermal processing, can effectively reduce, or even eliminate, the use of costly diluent, increase bitumen quality and market value, potentially decrease greenhouse gas (GHG) emissions, and

Water‐based drilling fluids formulated with mature fine tailings

open access: yesThe 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.

Readiness and Maturity for a Smart Circular Economy to Enhance Sustainability Performance: A Multidimensional Framework for the Hospitality Sector

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Research on readiness and maturity for the smart circular economy (SCE) remains fragmented, especially in the hospitality sector. This study develops a multidimensional framework that integrates the principles of the circular economy, Industry 4.0, and sustainability performance in the context of tourist accommodations.

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

Base‐Free Nickel‐Catalyzed Three‐Component Coupling of Aldehydes, Butadiene, and Malonate Derivatives: Toward Sustainable Synthesis of Highly Functionalized Molecules

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A nickel‐catalyzed three‐component reaction between arylaldehydes, butadiene, and malonates is developed yielding high functionalized homoallylic alcohols in a single step. No additional base is required and the reaction shows broad substrates compatibility with yields up to 96% and an exclusive selectivity toward the linear E‐isomer.

Instrumental activities of daily living in older adults with epilepsy: A cross‐sectional and longitudinal multicenter study

open access: yesEpilepsia, EarlyView.
Abstract Objective Instrumental activities of daily living (IADLs) represent a critical but understudied measure of day‐to‐day function in people with epilepsy (PWE). In the multicenter Brain Aging and Cognition in Epilepsy (BrACE) study of PWE ≥55 years of age, we examined the proportion, clinical correlates, epilepsy‐related predictors, and ...

Abnormal functional connectivity patterns in temporal lobe epilepsy—An international ENIGMA‐epilepsy study

open access: yesEpilepsia Open, EarlyView.
Abstract Objectives Temporal lobe epilepsy (TLE) impacts multiple brain networks. Aberrant functional connectivity has been demonstrated in resting‐state networks (RSNs) that mediate higher brain functions in TLE. This study aimed to identify the reproducible patterns of altered functional connectivity in TLE in a large, international cohort through ...

Genomic Insights Into Spatiotemporal Dynamics of Acquired Azithromycin Resistance Genes in Salmonella Strains Worldwide

open access: yesFood Safety and Health, EarlyView.
ABSTRACT Azithromycin has been used for clinical invasive infections caused by fluoroquinolone‐ and third‐generation cephalosporin‐resistant Salmonella, and mass drug administration with azithromycin has been used to reduce under‐5 mortality in children in some countries.
