From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp

Journal of Applied Polymer Science, Volume 143, Issue 16, April 20, 2026.
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

Intelligent online process fault diagnosis through integrating Andrews function, autoencoder, and neural networks

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 2033-2054, April 2026.
Abstract This paper proposes an online process fault diagnosis scheme that integrates principal component analysis, Andrews function, autoencoder, and multilayer feedforward neural network to enhance the fault diagnosis performance. Useful features are extracted from the online monitoring data by using Andrews function (also known as Andrews plot).

Unveiling the Anticancer Properties of New Synthesized Alkoxy‐ and Methyl Thio‐Chalcone Derivatives

Natural Sciences, Volume 6, Issue 2, April 2026.
ABSTRACT Breast and cervical cancers are a serious problem and the leading cause of death in women in this decade. Chalcone is a promising compound with great potential for anticancer use. In this work, we synthesized six chalcone derivatives with alkoxy‐ and methylthio‐substituents through Claisen–Schmidt condensation at room temperature.

Exploring Transfer Learning's Impact on the Explainability of Deep Learning Models for Wastewater Treatment Plants' Biogas Production

Expert Systems, Volume 43, Issue 4, April 2026.
ABSTRACT The growing reliance on fossil fuels for energy generation has raised concerns about their significant contribution to global warming and the associated risks of supply instability. Anaerobic Digestion (AD) within Wastewater Treatment Plants (WWTPs) offers a renewable alternative by producing biogas, while effective operational optimisation ...

An Efficient PdPt/rGO Catalyst for Hydrogen Electrolysis in Acidic Medium: Structure‐Activity Relationships and CO‐Tolerance

ChemElectroChem, Volume 13, Issue 6, 17 March 2026.
PdPt alloys supported on reduced graphene oxide exhibit enhanced hydrogen oxidation and evolution activity in acidic media. Minimal Pt incorporation into Pd tunes the d‐band center and weakens hydrogen and CO binding, delivering superior activity and CO tolerance.

CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

Advanced Functional Materials, Volume 36, Issue 18, 2 March 2026.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...
