Mechanistic Insights Into Sustainable Catalytic Pyrolysis of Biomass‐Derived Ferulic Acid: The Role of Alumina Regeneration

open access: yesChemistry – A European Journal, EarlyView.
Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

Readily Accessible bTurea‐Derived Nitroxide Polarizing Agents for Dynamic Nuclear Polarization: bcTCOOKs and bcTmols

open access: yesChemistry – A European Journal, EarlyView.
Two families of bTurea‐derived biradicals, bcTmols and bcTCOOKs, were prepared as polarizing agents for dynamic nuclear polarization (DNP)‐enhanced NMR through short and efficient synthetic routes. The best‐performing biradical, bcTCOOK‐M2, containing two methyl groups on the urea bridge, provided signal enhancements of up to ∼220 at 14.1 T and 100 K ...

Experimental methods in chemical engineering: The scientific method versus engineering design methodology

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Engineering graduate students confuse the scientific method and problem solving when presenting their pre‐doctoral exams and theses: Science discourse adopts question and hypotheses to assert and establish a study's rationale, while it is problem and objectives in engineering design.

Perspectives in biomedicine: Superfoods and antioxidant power classification

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The market value of natural food antioxidants will double to 8 billion USD by 2033, driven by a global consumer demand for ‘clean label’ products and proactive wellness solutions. However, the industrial application and health labelling (commercial brands) of these compounds remain severely constrained by inconsistent analytical methods.

Irregular visits in longitudinal studies: Comparing inverse intensity of visit weighting and imputation in a causal analysis of antidepressant therapeutic treatment

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Irregular observation times are common in longitudinal observational studies and can affect causal inferences. We use data from electronic health records of Kaiser Permanente Washington patients in the United States who initiated an antidepressant medication between 2008 and 2018, with a confirming diagnosis of depression. We are interested in

Does ESG Uncertainty Matter for Renewable and Nonrenewable Energy Consumption? Policy Implications in the Context of SDG 7 and SDG 13

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT In the discourse on environmental sustainability and energy security, energy management is an inevitable policy issue that requires research‐based solutions. Based on this, the present study contributes by examining the impact of environmental, social, and governance (ESG) uncertainty on energy consumption patterns in the USA from 2002 to 2024.

AI‐Enhanced Laser Manufacturing: A Social Life Cycle Perspective From the White Goods Industry

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainable manufacturing transitions require companies to demonstrate not only environmental and economic benefits, but also measurable advances in corporate social responsibility (CSR). Therefore, we propose using a guideline‐based Social Life Cycle Assessment (S‐LCA) aligned with UNEP (2020) and ISO 14075 (2024) to evaluate the social ...
