Electrocatalytic Methanol Oxidation in a Gas‐Phase Electrolyzer: Formaldehyde versus Dimethoxymethane Formation

ChemElectroChem, Volume 13, Issue 11, 3 June 2026.
A gas‐phase electrolyzer with a Pt‐impregnated Nafion membrane anode was used for selectively oxidizing methanol to formaldehyde (FA) with low water content. However, maintaining the cell temperature at 100 °C for extended periods led to membrane dehydration and low water content in the effluent, causing most FA to react with methanol to form ...

Evaporation of Microdroplets of Azeotropic Liquids [PDF]

The Journal of Physical Chemistry B, 2000
This work reports data showing the evolution of contact angle with time for mixtures of water and 1-propanol at room temperature on poly(methyl methacrylate) (PMMA). The composition range investigated spans the azeotropic composition, thus encompassing systems containing excess water and excess 1-propanol.

Molecularly Bridged Heterointerface Engineering: Designing Transparent, Wear‐Resistant, Hard yet Flexible Optoelectronic Protective Film

Advanced Science, Volume 13, Issue 31, 4 June 2026.
A molecular‐bridging heterogeneous interface engineering strategy is introduced to combine a polyhedral oligomeric silsesquioxane (POSS)‐based hard coating with a colorless polyimide (CPI)‐based flexible layer. The robust heterogeneous interface endows the integrated system with the superior properties of both layers and their synergistic ...

Advances in Systems Engineering of Carbon Dioxide Electroreduction

Carbon and Hydrogen, Volume 28, Issue 2, Page 150-171, June 2026.
Industrializing CO2 electroreduction hinges on holistic systemic synergy and optimization of all process segments rather than isolated catalytic breakthroughs; Process simulation is a core enabler to build a complete capture–conversion–product industrial chain, positioning CO2RR as a key technology for carbon neutrality.

Stabilization of Pd Active Sites by Defective NaY Zeolite Framework for Enhanced Stability in Dimethyl Carbonate Synthesis

EcoEnergy, Volume 4, Issue 3, June 2026.
A tailored‐defect strategy employing sequential high‐temperature calcination and acetylacetone treatment was developed to generate framework defects in NaY zeolite while preventing the formation of strong acid sites. These defects facilitate electron transfer from Pd to the zeolite framework and stabilize the Pd2+ active sites, thereby conferring ...

Determination of vapour–liquid equilibria diagram structure of five-component monoazeotropic system

Тонкие химические технологии, 2014
In this paper algorithm of determination of vapour-liquid equilibria diagram structure for five-component system with and without five-component azeotrope was described. This algorithm allows determining existence, sign of Poincare index and type of five-

A trust‐region funnel algorithm for gray‐box optimization

AIChE Journal, Volume 72, Issue 5, May 2026.
Abstract Gray‐box optimization, where parts of optimization problems are represented by algebraic models while others are treated as black‐box models lacking analytic derivatives, remains a challenge. Trust‐region (TR) methods provide a robust framework for gray‐box problems through local reduced models (RMs) for black‐box components, but they are ...

Energy‐Efficient and Sustainable Design Optimization for Ternary Mixture Separation: A Comparative Analysis of Sequential Iterative Optimization and Non‐Dominated Sorting Genetic Algorithm II

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT This study presents a comparative analysis of two optimization approaches: Sequential Iterative Optimization (SIO) and Non‐dominated Sorting Genetic Algorithm II (NSGA‐II) applied to the separation of ternary mixtures (1‐butanol, isobutanol, and 2‐butanol) using Dual‐Column Distillation (DCD) and Dividing‐Wall Column (DWC) processes.
