Muon imaging of hydrotreatment reactors

open access: yesJournal of Applied Physics
This study presents the design and simulation-based validation of a muon imaging system tailored for potential applications in industrial hydrotreatment units. The system is built around a two-panel plastic scintillator hodoscope, equipped with silicon photomultipliers and readout via a CAEN FERS-A5202 acquisition system.

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

SuFEx‐Enabled Reprogramming of Flavonoids for Selective α‐Glucosidase Covalent Inhibition

open access: yesAdvanced Science, Volume 13, Issue 47, 24 August 2026.
Selective inhibition of intestinal α‐glucosidase remains limited by poor enzyme specificity and off‐target metabolic effects. Here, SuFEx click chemistry is used to reprogram natural flavonoids into covalent inhibitors with enhanced α‐glucosidase selectivity and controlled reactivity. This strategy enables effective regulation of carbohydrate digestion

Pollutants Transformation During the Regeneration Process of Fluid Catalytic Cracking Catalysts

open access: yesAngewandte Chemie, Volume 137, Issue 52, December 22, 2025.
Fluid catalytic cracking is the main pollutant source in crude oil refineries due to spent catalyst regeneration. In this work, flue gas pollutants are monitored and coke deposits are identified. Operando and in situ spectroscopy are developed to explore coke species evolution, coupled with online gas infrared spectroscopy to detect pollutant formation.

Life cycle assessment of biodiesel synthesis from waste cooking oil using bifunctional heterogeneous catalyst

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1882-1894, July/August 2026.
Abstract The development of renewable energy sources is important in order to achieve the United Nations Sustainable Development Goals (SDGs). Waste cooking oil (WCO) is a promising feedstock for biodiesel production through transesterification. Heterogeneous bifunctional catalysts offer a sustainable alternative to conventional homogeneous bases such ...
