Regioisomerism Rewires Optical and Ion Recognition Properties in Azulenylsumanenes—Curved Non‐Alternant π‐Systems

Chemistry – A European Journal, EarlyView.
Regioisomerism rewires orbital topology and electronic polarity in curved non‐alternant π‐systems, switching both optical response and alkali metal ion recognition from Na+ to Rb+ selectivity. ABSTRACT Herein, we explore the fundamental concept of combining the molecular curvature of a molecular fragment of buckminsterfullerene with the pronounced ...

From Potentiostatic to Galvanostatic Control in Pulsed Electrochemical CO2 Reduction to Ethylene

Chemie Ingenieur Technik, EarlyView.
A two‐gap flow cell with three‐electrode configuration bridges the gap between H‐cells and industrial zero‐gap electrolyzers. Using ethylene‐selective CO2 reduction on copper as a model reaction, galvanostatic operation shows greater stability than potentiostatic control, whereas charge‐controlled pulsed protocols enable C2H4 selectivity under ...

Impacts of refining Canadian partially upgraded bitumen: Fluid catalytic cracking

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract In this study, we examine the fluid catalytic cracking (FCC) performance of vacuum gas oil (VGO) from partially upgraded bitumen (PUB), a novel refinery feedstock from Canadian bitumen. FCC experiments were conducted in a lab‐scale FCC unit with VGOs from two different PUBs prepared using thermal cracking and solvent deasphalting, along with ...

Role of Lewis centres on ethanol dehydrogenation over the Cu‐Cr/γ‐Al2O3 system

The Canadian Journal of Chemical Engineering, EarlyView.
Cu–Cr interactions on alumina enhance Lewis acid site density, boosting selectivity towards ethanol dehydrogenation products. Soft coke formation on copper and Cu–Cr sites drives deactivation, shifting the reaction towards unwanted dehydration products.

To FID or not to FID: Applying GANs for MRI Image Generation in HPC

Abstract With the rapid growth of Deep Learning models and neural networks, the medical data available for training – which is already significantly less than other types of data – is becoming scarce. For that purpose, Generative Adversarial Networks (GANs) have received increased attention due to their ability to ...

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

The 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 ...

Prevalence of functional iron deficiency in patients with malignancies and its impact on fatigue-specific quality of life

ESMO Real World Data and Digital Oncology
Background: Functional iron deficiency (FID) as defined by the European Society for Medical Oncology (ESMO) occurs in patients with malignant neoplasms and might be a target to improve fatigue-specific quality of life (QoL). The prevalence of FID in that
