Comparative Profiles of Lipophilic Nutrients and In Vitro Antioxidant Activity in Commercial Arabica and Robusta Green Coffee Beans

Journal of the American Oil Chemists' Society, EarlyView.
Integrated compositional profiling of ten commercial green coffee lots showed higher mean total phenolic content, DPPH radical‐scavenging activity, β‐carotene, and total phytosterols in Robusta‐labeled lots, whereas Arabica‐labeled lots showed higher mean total tocopherols and total measured fatty acids.

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Hybrid Inertial–Centrifugal Gas–Liquid Separator: CFD‐Driven Optimization Using Coupled Discrete Phase and Wall‐Film Modeling With Response Surface Methodology

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Efficient removal of liquid aerosols from compressed gas streams is essential in chemical and energy processes. Conventional separators relying on a single mechanism (inertial or centrifugal) struggle to capture both fine and coarse droplets simultaneously.

Electrokinetic Stabilization of Formation Fines Using Surface Modified Polymer Silica Nanocomposites During Low Salinity Water Flooding for Enhanced Oil Recovery

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Fines migration induced by low salinity water flooding severely impairs reservoir permeability and injectivity presenting a critical challenge in enhanced oil recovery. This study aims to synthesize and evaluate a surface‐modified polymer‐silica nanocomposite to mitigate clay mobilization and preserve the hydrodynamic capacity of porous media.

Advancing Environmental Sustainability: The Role of Artificial Intelligence in Monitoring, Predicting, and Controlling Sulfur Dioxide Emissions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Air pollution from sulfur dioxide (SO2) emissions poses significant threats to environmental sustainability, public health, and climate change efforts. Despite advances in monitoring and regulatory frameworks, traditional methods often fall short in accuracy, scalability, and efficiency.

Ice‐Droplet and Damaged Elastomer Interfaces: A Closer Look at Contact and Morphology of Anti‐Icing Coatings Using Cryo‐FIB‐SEM

Journal of Applied Polymer Science, EarlyView.
Cryo‐FIB‐SEM is used to mill and image the interfaces of ice droplets frozen on PDMS coatings damaged by abrasion and cutting. Both high‐ and low‐real contact areas are revealed for the first time, with interpenetration dependent on the shape of asperities on the damaged surface.

Polyurethane Foams From a Triblock Copolymer Polyol With CO2‐Derived, High‐Tg Polycarbonate Segments

Journal of Applied Polymer Science, EarlyView.
Polyurethane foam (PUF) properties are tuned by incorporating polyol with 0–15 wt% CO2‐derived poly(cyclohexene carbonate) (PCHC) segments (Tg = 104°C). Network PUFs are synthesized using CO2‐derived triblock copolymer polyol with PCHC hard segments and a polycaprolactone soft segment.

Barrier Properties and Crystalline Structure of Biowax‐Containing Water‐Based Polymer Dispersions Under Different Processing Conditions

Journal of Applied Polymer Science, EarlyView.
This study investigates the nanoscale structures of biowax materials using the wide‐angle x‐ray scattering method. The biowaxes are combined with water‐based polymer dispersions to create barrier coatings for fiber‐based food packaging materials.
