Microwave‐assisted catalytic pyrolysis of textile wastes: Synergistic effects and product characteristics

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study examines the microwave‐assisted catalytic pyrolysis (MACP) of individual and blended textiles (cotton, polyester, nylon 6) using ZnO and a ZnO/natural zeolite catalyst. In a custom‐built microwave reactor operated at 500°C, 1 kW power, and a 15‐min residence time, textile wastes were pyrolyzed.

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

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

Binder-jet printing and pressure-controlled infiltration for fabrication of high-temperature, low-dead-volume microfluidic interfaces

open access: yesAdditive Manufacturing Letters
Interfacing is a consistent weak point in the manufacturing of microscale gas chromatography columns. Current techniques for interfacing with microfluidic systems often degrade under high temperatures and thermal cycling and suffer from dead volumes.

Non‐Invasive Estimation of Systemic Drug Exposure Using Exhaled Breath Metabolomics in Humans: A Translational Proof‐of‐Concept Study

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Accurate assessment of systemic drug exposure in humans remains challenging, as conventional approaches rely on intermittent blood sampling and laboratory‐based assays that are invasive and provide limited temporal resolution. Exhaled breath contains volatile and semi‐volatile compounds arising from drug metabolism and downstream biological processes ...
