Constructing Enzyme‐Inspired Multisite Synergistic Catalyst for Promoting CO2 Electroreduction to Ethylene at pH Universal Condition

Carbon Energy, EarlyView.
A rational synthesis strategy was developed to construct enzyme‐inspired Cu‐AM catalysts with well‐defined multisite architectures. This catalytic system enables highly selective electrochemical CO2 reduction to C2H4 under pH‐universal conditions, delivering exceptional Faradaic efficiencies across acidic, neutral, and alkaline electrolytes.

Triptycene‐Based Tripodal Molecular Platforms: A Comparative Study of Photoswitchable Langmuir–Blodgett Films on Metallic and Nonmetallic Surfaces

Chemistry – A European Journal, EarlyView.
A modular triptycene‐based platform enables the preparation of Langmuir–Blodgett monolayers of structurally diverse molecular photoswitches on quartz and gold. Surface‐sensitive characterization and optical spectroscopy demonstrate that the intrinsic switching behavior is retained after surface immobilization. ABSTRACT Photoswitchable molecular systems

An Analytical Design Model of a Vacuum Pressure Swing Adsorption Process for Biogas Upgrading

Chemie Ingenieur Technik, EarlyView.
A steady‐state model was developed for a vacuum pressure swing adsorption (VPSA) process comprising adsorption, depressurization, and evacuation steps. The resulting analytical plant design model provides the optimal adsorber height required to achieve a target product purity with maximum bed utilization.

Application of artificial neural network and general machine learning modelling on CO2 adsorption in moisture equilibrated South African high and medium rank coals

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.

Experimental methods in chemical engineering: Cyclic voltammetry—CV

The Canadian Journal of Chemical Engineering, EarlyView.
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 ...

Photometric Diagnostic of the Sheath Dynamics and Electron Density Trends in Single and Dual Frequency CCRF Argon Plasmas

Contributions to Plasma Physics, EarlyView.
ABSTRACT A methodological study is presented on a noninvasive photometric diagnostic for determining trends in electron density and sheath dynamics in single (1f) and a dual (2f) radio frequency capacitively coupled (CCRF) argon plasmas. The 1f discharges are operated at 13.56 and 27.12 MHz, respectively, while the 2f discharge is driven by both ...
