Experimental methods in chemical engineering: Cyclic voltammetry—CV

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5776-5827, November 2026.
Abstract Cyclic voltammetry (CV) is a foundational electroanalytical technique for investigating redox behaviour and evaluating material performance across fields such as molecular electrochemistry, electrocatalysis, sensing, and energy storage. Despite its widespread use, a gap remains between formal electrochemical theory and the practical data ...

The Transformational STEM Consciousness Scale: A QuantCrit Measure of a Liberatory STEM Outcome

open access: yesScience Education, Volume 110, Issue 6, Page 1654-1672, November 2026.
ABSTRACT Guided by QuantCrit, we introduce and validate the Transformational STEM Consciousness (TSC) scale, which fuses students' motivation to pursue racial and social justice through STEM with a critique of STEM's historic complicity in inequity. Surveying 255 undergraduate and graduate students in 18 justice‐integrated STEM courses across 11 US ...

Photosensitizing Au(I) Catalysis With Coumarins

open access: yesChemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐

One‐Shot Pd(II)‐Catalyzed Multiple C–H Activation Enables Modular Construction of Fluorenylidene Oxindole‐Based Multi(Polycyclic) Aromatic Enes

open access: yesChemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
A one‐shot Pd(II)‐catalyzed C─H activation strategy enables the rapid conversion of simple linear propiolamides into structurally diverse mono‐, di‐, and tri‐olefin‐bridged MPAEs. This cascade process orchestrates up to six sequential C–H activations in a single operation, providing streamlined access to highly conjugated architectures.
