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

open access: yesAsia-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 ...

Enhancing the Performance of Aqueous Lithium‐Ion Batteries via N‐Methylpyrrolidone Additive

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Aqueous lithium‐ion batteries (ALIBs) have garnered significant attention in the field of energy storage due to their inherent safety. However, their practical application is severely constrained by a narrow electrochemical window and electrolyte crystallization at low temperatures.

Evaluation and Optimization of COD Removal Performance for a Domestic Wastewater Treatment Plant by Response Surface Methodology: The Case of Van Muradiye

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, the performance of the Van Muradiye Domestic Wastewater Treatment Plant was evaluated with Response Surface Methodology (RSM). The effects of pH, conductivity, dissolved oxygen (DO), and suspended solids (SS) on the chemical oxygen demand (COD) removal efficiency were evaluated using samples collected from the plant's inlet and ...

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

open access: yesJournal 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.

Morphological variation of the conus arteriosus in Chondrichthyes: Implications for ecology and evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract Cartilaginous fish have diverse morphological traits that are essential for understanding their evolutionary history and ecological adaptations. However, the conus arteriosus and its valves, key components of the heart and blood circulation, have been underexplored in phylogenetic and ecomorphological contexts.
