Pharmaceuticals Made with Hydrogen: A Sustainable and Efficient Approach Using Flow Synthesis

open access: yesChemistry – A European Journal, EarlyView.
We demonstrate a sustainable strategy for pharmaceutical manufacturing by combining hydrogen, heterogeneous catalysis, and continuous flow synthesis. The development of novel catalysts and their application in a multi‐step synthesis of donepezil enabled a highly productive process with no intermediate purification.

Controlled Formation and Unusual Reactivity of Cyanohexatriyne (HC7N), a Synthetically Challenging Interstellar Cyanopolyyne

open access: yesChemistry – A European Journal, EarlyView.
First controlled formation of cyanohexatriyne (HC7N) is achieved using a cobalt–alkyne masking strategy that overcomes the intrinsic instability of nitrile‐substituted polyynes. The approach enables spectroscopic validation of HC7N and reveals its pronounced electrophilicity through a selective conjugate addition with diethylamine.

Release of multicomponent pheromones from porous fibres

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Surface engineering empowers a polymer exclusion net to serve dual functions: physical exclusion and pheromonal release, allowing for pest control in agricultural crops. In previous work, a net woven from porous fibres releasing simple, single‐component alarm pheromones showed promising results in field tests.

Bayesian inverse ensemble forecasting for COVID‐19

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Variations in strains of COVID‐19 have a significant impact on the rate of surges and on the accuracy of forecasts of the epidemic dynamics. The primary goal for this article is to quantify the effects of varying strains of COVID‐19 on ensemble forecasts of individual “surges.” By modelling the disease dynamics with an SIR model, we solve the ...

Digital Product Passports in Fashion: A Strategic Framework for Implementation

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study investigates the role of the Digital Product Passport (DPP) in promoting transparency, traceability, and sustainability within the fashion industry. As the fashion sector faces significant environmental and social challenges, including resource depletion, pollution, and unethical labor practices, the DPP offers a potential solution ...

Sustainability Assessment of Micro, Small, and Medium Enterprises: A Systematic Review and Hybrid Architecture for Credible, Salient, and Legitimate Knowledge Governance

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainability assessment advances corporate social responsibility toward inclusive development. Widely recognized approaches prove inadequate for micro, small, and medium enterprises (MSMEs), resulting in fragmented proliferation that hinders cumulative knowledge.
